Ok this car gets a very good 60ft..and they said it has around 450 rwhp which is possible with its trik flo heads, fast intake, the cam specs in the article. But how is it possible even with its 3188 raceweigth to trap 138mph and do 9s. ?This seems against all the laws of physics! I would seem to me it will require at around 700 engine to go 138mph in the 1/4. And this is stock bottom block no spray , no turbo or super. They even checked the bore and stroke in the article. How can this be possible. Are there any other similar modded vettes or f bodies running anything close to this mph with so little hardware?

Baffling..

Check out corvetteforum.com there a guy with screen name "robZ". Check him out. This is under the Z06 fastlist. I believe he got head/cam, gears. He might be on this site too. Not sure though.



9.985 @ 138.80--1.428 --robz

But, I don't think there are many of those cars. He's a really good driver.

There's an AMR cam only car over in the Eastern section (Demonicbird00) that has gone 10.99.
Car went from 98.11mph in the1/8 to 127.45mph in the 1/4
That's 2 cars outta there that I know of with big MPH differences from the 1/8 to the 1/4
Both stick cars.
They must be doing something right over at AMR

I think he has a killer setup and didn't come up with it overnight. He has that car hooked up for sure. Seen alot of people complaining that there is no way he can get 30+mph in the last 1/8 mile. Well I got 24mph in my last 1/8 and my car only had a CAI on it, 92.77 in the 1/8 and 117 in the 1/4.
I believe rob and what he has done. He said it is all in the keeping the motor in its power range. Anybody can spend money on heads and a cam. He tried lots of different setups and found the right setup.
Wierd how a bone stock C6Z can run high tens with et streets, then a car like rob's come along with more hp than that car, plus suspension mods, trans, etc. and pulls a high 9 and lots of people complain. He beat the ever livin snot out of that car going down the track. As in the video above. Don't forget about the video of a CAi and full exhaust mustang gt in the high 11's. Yea he beat the piss out of it, just like rob, but he did it.

forgot about that:
East coast DA'???

That alone is good for 4 tenths Some killer times on the east coast too!

Its all in the setup of the car and rob nailed it, big time! The article in GMHTP backs up rob and his car. Besides if I was him and owned my own shop i wouldn't tell everybody what is done to the car. That would just ruin what he has accomplished by every other shop out there use that setup.

I have talked to hiim on the phone before and he was very helpful with my questions about a clutch for my car and how to set it up.

He should be unbanned from this site. Weird this is something that somebody would be banned at the corvetteforum for.

Sounds like a two step to me. Like its building boost . Thought it might be rear mount turbo at first.
The article lists type of heads. the cam metnioned sounds pretty tame.The compression is listed at 11.5 likey from heads shaved as it says stock bottom end. They also say it makes 450 rwhp which sounds about right..trik flo heads, fast 90/90 tb and the mentioned pretty middle of the road cam.
So again if you forget the et and just crank in mph there is no way in hell a 450 rwhp car can do 138xx mph. Don't care if GOD HIMSELF was driving! Something don't add up.

I can see some crazy numbers if you go to like 15 to 1 compression, a stupid crazy solid roller cam, awesome heads then could see a stock displacement
ls1 making maybe 600rwhp and turn some 138mph times maybe..if it was light and this car is reasonably light.
Almost any buddy that is even approaching 138 mph on 346 is running all the bolt ons with big spray or FI.
Its really a simple question. How can 450rwhp do 138mph. Buddies m6 which ways maybe 400 pounds more does 11.8 best at 116 or so at 1600 ft track on et streets doing think it was 1.8 60fts. So sure he could be getting maybe 11.0 if he got the 60ft down to 1.4 but his mph isn't going to go up because of that. He has 420rwhp.Heads,cam,headers bolt ons.

I dont' care what something is still messed on that car..

I love Mustang dynos! :devil:

Weird everybody says that dyno's aren't true of what the car can do and to run it at the track and see what kind of numbers it puts down. Now we have this car and everybody is talking about how can a 450rwhp car run 138mph. :eyes: See some cars that get 450rwhp and run like shit and some that are insane. So this is the case with robs. My car with just a decent size cam put out 440rwhp, so i highly doubt that robs is only putting out just 10 more rwhp with a little bit smaller cam and a great set of heads. :chug:

I need to go and pick up this mag! Was following his write ups on his car since the beginning, since I wanted to do something similiar to his, but all it takes is $$$$$$ and that ran out.

Looks like some people have the money to throw into the car but have no idea or patience to set the car up right. I'm sure rob spent a decent amount of money but put tons of time into the car. Look at the end result.

MY99TAWS6
03-29-2009, 11:56 AM
mustang are not that much lower so even with 500rwhp which is really hard hard to get with a pretty mild cam ,decent heads, and 11.5 to 1 and headers. Still 500rwhp might give 125mph or so not nearly 140mph.

I guess have to side on the doubting thomases side. This car just makes no sense. Mph shows true hp the car is putting out better than et. A 1.4 60ft is awesome for et but don't do much for mph.

But the videos show the car running what it runs. So can't really explain it but it seems to transcend the laws of physics.

You may want to check out untuned C6Zs with DRs. They have trapped up to 129+ mph and have nowhere near 500 rwhp.
Obviously, you have your doubts and nothing will convince you otherwise; even a reputable publication. So you might as well stop :bang: because it will only frustrate you. However, stay tuned for more amazing feats.

Ok did some googilng and found this one..

CorvetteForum showing that Jamie Furman, driving a stock C6 Corvette Z06 with run flat tires got under 11 seconds, 10.98 to be exact at 129 mph at the Maryland International Raceway. The time was validated by an official at the track, setting the record for the fastest production vehicle! and not sure what alititude maryland was or the density air that day. Could be some more potential for more mph for sure there and quicker et. And of course that time was on runflats not even drag radials. And forgot would assume vettes gain some mph over fourth gens due to superior aerodynamics?

So assuming z06 c6 dyno around 400?? So I guess taking into acount some weight reduction and good density air/alititude and maybe a mustang dyno reading 10 % lower than dynojet looks more doable.

So then there should be quite a few 500rwhp c5 stock displacment cars that should be able to duplicate the mph of this car if not the et and 60ft. So what are the closest to this?

I guess was going from our track where the alt is 1600 and density air can be a lot worse most days. As said car club guy with SS pushing 420rwhp dyno can only manage about 118mph and weight is about 3600 raceweight. So quick figuring add another 4mph for weight form 3188 to 3600. Add another maybe 4 mph for alt or density air maybe even 6 tenths. So we now get like 128. And if it was mustang dyno then starting to make some sense.I want to see the dyno sheets though. From an independent shop.

Rob has been banned from here.. I'm guessing because shops like TSP are pissed that AMR is beating their gutted racecars by almost 4mph in the 1/4.

If TSP is going 134 MPH in +1700 D/A with an automatic and a large stall converter, and this C5 is going 138mph in -1700 D/A with a 6-speed, I'm pretty sure no one at TSP cares... The two cars are completely different in aerodynamics, drivetrain and setup, similar only in the fact that they both have stock 5.7L shortblocks.

Anything above 128mph with stock cubes and N/A is moving on pretty well, really anything above mid 120's is doing good. I am impressed with Robz's car and I believe the times. I have not seen the new GMHTP issue, but look forward to it just for this article.

Just to add a little to this, the corrected dyno numbers don't mean squat when racing at a below sea level density altitude. I hate to make the correlation, but it's like an N/A engine with a little bit of boost, some of the math savy guys might be able to give you better example. Same situation as to why stock LS1's run mid 14's at 7000 feet D/A when they run low 13's and 12's at sea level tracks.

Cartek has a heads and cam car (Alex's car) that dynoed just over 500 rwhp on Cartek's dynojet. It can be done. I don't know sh*t about a mustang dyno only that I know it usually reads lower hp #'s.
Robs vette is under 3200lbs and Cartek Alex's is heavier (don't quote me but I think it was just over 3300lbs).
Alex ran 10.3@ like 132mph at Etown, not Atco where the air is better and the track hooks better (those of us who have raced at both know the deal).
Rob had a great day condition (da) wise-has a sick clutch and trans, is more aerodynamic, is lighter and has alot more $$$ is his car than Alex has in his (Alex still has the stock brakes in his car). Alex runs taller 28" tires, which really eat up the mph, Rob runs 26's I want to say but they may have been 27's-no way they are 28's.
I personally was at the track on the night at Etown when Rob ran a 10.17 I beleive it was.
So if you want to compare the 2 cars I'm using as an example at the same track and similar conditions (I was there when Alex ran his best time as well) there is less than 2 tenths difference between the 2.
Also rob ran his time at a rental day, when you can really fine tune and hot lap the car for a better et and mph, Alex ran his best time on a t+t night at Etown.
Also both racers can really shift their ass off.

I don't see what's so unbeleivable when comparing the 2 cars.
Also another really important piece to mention in both these cars is that they both have great tuning. Tuning is key and to be honest-some people (shops) just can't tune as well as the guys that tuned these 2 cars.

Mark,
Actually Rob's pass was at a Test & Tune night at Atco. The air was decent but not optimal. We have another vid somewhere showing Rob writing his time in the dew on the top of his car. And you are correct about great driving & tuning producing great results. That is why AMR has produced the quickest stock bottom end N/A corvette out there as well as the quickest bolt-on only C5Z corvette.

ohhhhhh brandon I apologize, for some reason I thought you were an AMR car. So Fran did your set up. But my error kinda makes my point even more about the mph from the 1/8 to the 1/4 and how you and Robs cars accelerate very well between those points and how competent shops and skilled racers can get down the 1/4 in a hurry.

I thought Rob ran his best time at a rental :confused: , makes the pass even that much more impressive.

Great ET and MPH, I am impressed.

A corvette is very aerodynamic and the engine compartment is sealed up tight as well, very light weight clutch, efficient tranny, excellent driving and great engine combo makes for a impressive set-up.

I would bet it makes more than 450 to the wheels on a dynojet, if they are not making upwards in the 480+ range then there is more on the table with more tuning.
215 heads and that size cam should make 480+.

As for questioning their track numbers, I believe anything is possible, might be what is the norm but it can be done.

here goes that dead horse again, hehe
Alex as well as other members had issues and doubts about the setup, one issue I remember in particular was the vehicle raceweight (Alex had mentioned as well as others).
It was stated, I think by Rob, that this was a full weight vehicle. This was challenged on the boards and never settled at the time.
Robs raceweight is 3188lbs as stated in GMHTP yes?
Stock c5z06 curb weight (without fuel) is what, 3120lbs or so?
So unless Rob drove his car by remote control, or weighs 70lbs or so (he'd have to weigh less with fuel), this car is not full weight.
You can't blame Alex (or other members) for questioning a set up that doesn't make sense to them. This is LS1"TECH" , guys are going to ask questions and they are going to want answers that MAKE SENSE.
The issue of vehicle weight was a HUGE topic of conversation, along with other things back when.
I don't like alot of things Alex said during that time, I don't like some things you have said either, it's all unfortunate but I don't think Alex owes Rob or you guys an apology for the back and forth comments because you were all doing it and he certainly doesn't owe an apology for questioning a set up that didn't make sense at the time.

I'm sure for some reason Rob mispoke about the raceweight, car is defiantely not gutted out-looks great in and out. I've got to think that maybe he just didn't know the true weight of the vehicle at the time for whatever reason, etowns scale is always off.

Mark,

Never was it stated the car was a full weight vehicle, the very first post of the original thread states http://www.ls1tech.com/forums/10384969-post1.html The car is a street car with some minimal weight reduction.

A Bone Stock Z06 with 1/4 tank weighs 3080 no driver, where robs car with 1/4 tank was right about 3015 no driver. 65lb weight reduction is minimal in my book.

And mentioned again on post #6 about the brakes http://www.ls1tech.com/forums/10385217-post6.html I sometimes run with the passenger seat out, have a drag pack, and smaller front brakes that I purchased with the wheel package.

I've got to think that maybe he just didn't know the true weight of the vehicle at the time for whatever reason.

Thanks for helping me beat that horse, brother.:lol:

As I recall, a certain "someone" insisted that Rob's car weighed something significantly less than 3100 lbs and that he was not forthcoming on that. I don't see where the weight reported is anything out of the ordinary after one does the obvious weight reductions (passenger seat out of the car, lighter wheels, dumb bells removed from the trunk:D, etc).

research I did showed the stock c5 zo6 weight without fuel at 3117
http://www.z06-corvette.com/specs/engine-drivetrain.htm
Robs car without fuel is 102lbs lighter than that.
His car weighed 3015 with 1/4 tank? that's at least 3-4 gallons no?
conservately 5 lbs per gallon that's about 15lbs if not more.
Now you're looking at 117 lbs conservately.
Add that 117lbs and you're looking at a 10.1x pass.
shoot add just the 17lbs and you're at 10.0x
117lbs on a zo6 is a little more than "minimal" IMO but everyone is different, that's why words like "minimal" "estimated" "right about" " sometimes" "smaller" "mustang dyno" "street car" are all open to discussion. That's why you're supposed to DISCUSS them if you post them. lol :)

research I did showed the stock c5 zo6 weight without fuel at 3117
http://www.z06-corvette.com/specs/engine-drivetrain.htm
Robs car without fuel is 102lbs lighter than that.
His car weighed 3015 with 1/4 tank? that's at least 3-4 gallons no?
conservately 5 lbs per gallon that's about 15lbs if not more.
Now you're looking at 117 lbs conservately.
Add that 117lbs and you're looking at a 10.1x pass.
shoot add just the 17lbs and you're at 10.0x
117lbs on a zo6 is a little more than "minimal" IMO but everyone is different, that's why words like "minimal" "estimated" "right about" " sometimes" "smaller" "mustang dyno" "street car" are all open to discussion. That's why you're supposed to DISCUSS them if you post them. lol :)
see what I mean when I say it's the "tech" info that we are OBSESSED with,lol.
This was the main issue now known as the "Dead Horse". :jest:

Your research is wrong b/c that is the listed curb weight and NOT an un-fueled vehicle

curb weight 
–noun the weight of an automotive vehicle including fuel, coolant, and lubricants but excluding occupants and cargo. http://dictionary.reference.com/browse/curb+weight

Here are some fellow board members who have actually weighed their cars http://www.ls1tech.com/forums/corvette-performance/1032976-factory-weight-c5-z06.html

So basically all your other numbers above are not warranted, and besides... the fact is the car ran what the car ran.

I agree on the point that certain words lead to open interpretation, however Rob has always been forth coming and has provided more than enough proof with video's, timeslips, dyno graphs, and all weight reduction measures taken.

This particular dead horse along with others mentioned like Nitrous and/or a larger cube motor is only alive b/c of inaccuracies posted by others to try and make things not seem legit.

Dude...you are funny...I like that.:thumb:

I think there were a couple of your "camp" who suggested Rob's car weighed in the range of 2800 lbs. So, if we say 3100 for shits and giggles is a stock Z then we're talking ~300lbs = ~10% which = significant, as opposed to a 3% - 4% reduction (which is what his car might have)...not trivial either, but very different from 10%.

Remember..."a horse is a horse, of course of course"...can you finish it?:D

Ahhhhhhhh, so you're "minimal" weight reduction of 65lbs is accurate because I didn't consider the vehicle as fully fueled, cool I learned something new today. :cool:

Rob was forthcoming yes, until he got offended and clammed up. :)
I still disagree that the questions of "how" it was done was to make it seem illegitimate.
Then it escalated and got out of hand.
I get asked all the time if I run nitrous, I take it as a compliment, most guys I know would too. Want to look under my hood-go ahead, I don't run NT at the track. Knock yourself out.
When Rob and you guys wouldn't allow it-it really was an issue for alot of people.
Look at the car, weigh the car, hi 5's all around and everyone is happy.

Cartek had a similar thing like this happen. they got accused of running a stroker on a heads/cam car by a well known corvette racer we all know but I won't mention the name.
This guy was so adamant about it that Cartek invited him to the track one day, he witnessed the car run the #, followed the car back to Cartek where they tore it down right in front of him. He was a man and apologized publically and bought the boyz lunch.
I'm not saying everyone should tear the motor down for everybody who questions a set up and at the time Rob ran the # we did agree that a visual inspection and weight verification would be adequate, but you guys didn't agree so the problems came.

Columbus had to prove the Earth was round, Einstein had to prove his theory of relativaty and Rob had to prove his shit works like he said.
Unfortunately he waited for the March issue of GMHTP to prove it. ;)

This horse is soooo f*cking dead already.

I would like to see everyone take thier dresses off and stop acting like a bunch of girls and just get along and get back to racing and such.

what do you b*tches say? :jest:

No one believed the world was round either. They thought you'd fall off if you got to the end. You sound like one of those people.

He ripped off THREE 9sec passes, then they tore the engine down right there and went over the car with a fine tooth comb. Why are you having so much trouble believing this? He even has the bore and stroke pictures in the magazine!

The weight, power, or a combination of both has to be wrong in that article to run 138.

I read the article, and I recall the argument about how legit, or not legit the car is.

I do admit, that by the old trusted slide rule for a 3180 lb car to run 138 mph, you're talking about making over 625 hp at the crank.

I guess it's possible. I'd be more intrested in seeing the car show up and make some runs in july when it's 90 degrees outside and the da is in the 3000+ range. I think that would put all the doubt's to rest.

Uncorrected power is what you race at, 625hp is not unbelievable to me if we're talking flywheel hp. The stock shortblock can surprise you sometimes. ;)

Q for whomever works on this car:

What kind of vacuum pump and/or oiling system does this car have? Wet Sump, A.R.E. Dry Sump, etc?

What shocks? (may be mentioned somewhere)

Once again, congrats for a fast timeslip! I've worked on some big powered C5's a few years ago and they are not easy to get down the track.

I re-read that article two or three times already...I was amazed until I started thinking about f-bodies breaking 10's w/ H/C/I, here is my take:

Lets say your LS1 Trans Am has 450 rwhp...
Your race weight is 3600
You cut a 1.6 sixty
You squeak into the 10's and maybe run a 10.8 when it is dialed in.

Rob's car:
Race weight is 3188, there is 4 tenths (100 pounds per tenth, which I assume is actually more when running this fast, but for arguments sake)
He cuts a 1.41 sixty, there is 4 more (2 tenths down low=4 on the big end)
His setup is perfectly dialed and he leaves at 5800-6200 rpm (as per GMHTP)
He also has 4.10's and a softlok clutch (which they said helps on the back half but also helps him get out of the hole quicker, I don't know a lot about clutches)

There is two more tenths in setup and testing, plus his C/D is better than your f-body iirc.

Feel free to discuss, this is just my theory. :)

hey guys, I have been following this for awhile and at first it was hard to believe , but I just went a 9.92 @ 138 with my f-body. There is no way in the world I would have thought that it was possible to go that fast after seeing the car make 475 rwhp on fms dyno also @ 3100lbs. A well tuned motor and suspension makes alot of this possible. Turning potential energy into kenectic energy is the major part, putting power to the ground and keeping the motor in the sweet spot.:D

05-07-2009, 01:29 PM
Don't leave out the 500 pound weight difference either, as if DA and trans type were the only real differences..

if we're going to make comparisons, lets be fair now

Let's look at the math again, while we're being fair :)

3188lbs - 2865lbs = 323lbs

05-08-2009, 08:06 AM
The fastest H/C N/A C6 ZO6 Ran 9.8@139mph WITH 587RWHP and 3200lbs with driver if I'm not mistaken its really suprising that 470rwhp would run the same ET and MPH.


But none the less Rob's car is freakin mean and ran awesome times.

What transmission does it have ??? stock?? rebuild?? proshifted??

Looks like its leaving on a small shot to me but for a H/C car that mfer runs like a scalded dog.

EDIT: Something just crossed my mind. Sometimes in the ADRL, people get runs tossed for low hanging engine diapers. As you all know something hanging low trips the beams before the rear tires. But this generally only helps ET.

Carry on.

There's an AMR cam only car over in the Eastern section (Demonicbird00) that has gone 10.99.
Car went from 98.11mph in the1/8 to 127.45mph in the 1/4
That's 2 cars outta there that I know of with big MPH differences from the 1/8 to the 1/4
Both stick cars.
They must be doing something right over at AMR

here's a 3rd for you. best to date mph 1/8 99.71 1/4 126.91mph. 10.752et. hope we can squeeze another 2mph out. oh by the way another amr car. 435 rw through a a-4 3600 stall stock bottom

Yep, new 388ci all bore motor

We made 596rwhp 495rwtq on a Mustang dyno that reads 10-13.5% lower than a dynojet.
roller cam
tfs 245heads
4.10 gears
~104 octane

Peak power was climbing @ 8000 but the car will not go above that.
The stock PCM is shutting off the fuel. Have to look into that one some more to rev the motor out further.

First pass out we ran 9.64@143+ 1.39 60 ft

We have a few goals and met 2 of them on the first pass, which is just insane! 1st was just to beat our old times with the 346 H/C, 2nd was to beat the N/A corvette record held by our good friend Danny DBN with his 427 auto C5, and last goal is to take the C5 six speed record.
