Street Racing & Kill Stories - supra onwer laying down the law

i hate those cars but this one is actually fast

Supra seems to dominate from those roll races. Did not see this coming, feels like watching Dexter season 4 finale all over again haha

Oh and daytime vids FTW!

Supra seems to dominate from those roll races. Did not see this coming

Really???

As far as I knew supras preferred roll racing cuz thats where they shine.

And YES daytime Vids FTMFW!

Nice job! Those damned Supras are still around and taking names. Just not so easy for them to rule the roost like they used to though! LSx's in most cases are there 'Huckleberry'.

Hey bad_408: Right here is his sarcasm: <--------------------->













And right here is the top of your head: <-------------------------->

His sarcasm flyover must have cleared you by at least 27k feet. :)

So who didnt see the nitrous bottle in the back of the camera car in the last 3 seconds? lol single turbo plus nitrous i bet that things nasty.

Yea it seemed like it was a tick faster than that ROE supercharged rt10 viper....


stock gen2 rt10 viper=405 rwhp and 12.1 at 119 mph

ROE supercharged gen2 rt10 viper=570-600 rwhp and 10.9 at 130 mph

pretty impressive Supra

What I would do to have the money to ruin a supra owners day :nod:

There is plenty of faster cars all over. Just so happens at this meet we only see him beating people. Who knows since he is the one showing the video he might have lost to some but just didn't post them. Even if he didn't lose thats not to say that he cant. They aren't God's engine or anything. Just seem to attract people with shit tons of money. Every time ya see one of the fast ones selling its always 50k+. They put a ton of money into them. There is alot of people on here that have done the same that would ruin his day.
Looking at how he beat that viper I'd doubt he is in the 9's with the setup he was running there. I dunno if he was on kill mode there so I cant say if there is more in that supra but...

I'm confused man... is that NOT your Viper in the video? The one in the vid doesn't have a slotted hood from what I can tell, it looks to be a bit older than yours. I thought you had a 2003 viper srt10.. but your pic makes your hood look like the gen 4 one. What's the deal??! :eek2::eek2:

thats not my viper...I had a red one like that before though...

That supra probally runs high 11's or low 12's at 130-133 mph...But in these races that dosent matter..In these roill races it pulls like a solid 10 second car..

Those cars are laggy...

car might pull a 8.5 1/8 at 90 mph and then end up running a 11.8 at 130 mph..The back 1/2 for them is crazy fast...

Thanks for clearing that up lol. What year is your viper though?

The problem with Supra's is getting them to launch from a dig. Once that's address and figured out they are just as fast. Lag isn't a problem anymore with proper single setups. QSVs or other options. That supra wasn't that impressive not sure what mods he has or turbo he's running.

Running on the highway is where the supra will always shine. Not much has a chance.

If any of you are in the Chicago area we go out every weekend pretty much. Most of the GM guys that come out won't play with our supras though... They get all butt hurt after they lose.

^^^^:zzz:

hes on the bottle too

damn thats fast and yes daytime vids for the motherfuckin win!!!

My vipers a 2003...

And yes that was a impressive supra. ive raced more of them than i can count..As well my friend had a Roe supercharged 1997 Viper that trapped 127-130 mph in the 1/4 mile and no supra was touching him..

the roe supercharger plus nos that viper went 9.9 at 140..I think on just the supercharger it went high 10's at 130...

the supras ive ran despite haveing big power wernt really that fast untill the 700 rwhp mark...

400 rwhp..slow

500 rwhp..ugh...

600 rwhp...good run for the Viper

700 rwhp..then they start getting fast........


heres my viper at 475 rwhp against a 6xx rwhp GTR...
http://www.youtube.com/watch?v=S-SkEvxjmuU


heres a 6xx rwhp supra against the same 6xx rwp GTR...
http://www.youtube.com/watch?v=a5XoPMbyATo


I raced this supra 5-6 times and smoked it pretty easily in the 1/4 mile


heres my 450 rwhp viper against a 600 rwhp supra
http://www.youtube.com/watch?v=h2rBiMEyI84


To me they start getting fast at 700 rwhp...My buddies 700 rwhp supra was able to tie me in the 1/4 mile and walk away from a roll...

another guys 700 rwhp supra was able to walk away from my 450 rwhp viper..


But the 600 rwhp or less ones dont seem that fast to me..

im thinking the supra in this vid was 700-800 rwhp to run with that supercharged Viper

Every big single turbo supra, or other small displacement big turbo car, would be greatly benefitted by a quick spool valve and anti lag for the more hardcore.

As is the lag makes 600whp supras close runs to your viper, which has instant power with 8.4L and no turbo.

that yellow viper sure could have used a better driver but im still pretty sure he would have got pulled

What the hell was up with that porn music in the first video lol?

At the 30 second mark I busted out laughing hahaha....

At the 30 second mark I busted out laughing hahaha....

You stole my post. Very 1989 porn music in that first video...:corn:

Back in the mid 2000's their was a guy that would show up to a few F-body dyno gatherings with a red 750+hp TT Supra. Back then I never knew those cars could make that much horsepower. He'd come out on top nearly every time at the end of the those sessions as the king of horsepower over some stout stroked, blown, n/a nos LS1's. Love them or hate em you gotta respect some of them if they're still on the road!

750 is nonthing....Those things can get up around 1500 rwhp!

Very 1989 porn music in that first video...:corn:

your sure it was 1989, on the dot?? lol

your sure it was 1989, on the dot?? lol

Oh I'm too sure...not one month past.

:lol:

Cool
I am a Supra owner that loves races from a dig!!!

Supra's Making The Import Kids Cream In There Pants Since 1993 (Mark IV)!

When it comes to 180mph+ roll on's it hard to run down a GT47+ Supra thats built right. The drag coefficient on an Fbody is just not as good as the Supra, and their heads in stock form outflow most of our high dollar heads. Their transmission is better and the ride at those speeds is much more stable. They cost a fortune though to make 1200-1500rwhp, and they break quite frequently at those levels as well. You can easily maintain an exotic for the same price as a high end built Supra. The best thing GM has made to run one down would be a well built turbocharged, LSx blocked, C5/6 Vette. You would want the standard C5/6 as it has a Drag C/O that is very close to the supra if not a little better, and with the LSx you can up the boost to run one down.

... and their heads in stock form outflow most of our high dollar heads

No.

CNC Ported Stage 3 GM L92 (http://www.livernoismotorsports.com/product.phtml?p=1536) Cylinder Heads from Livernois
Intake Flow Rate 360 CFM
Exhaust Flow Rate 245 CFM (275 CFM w/ 1 3/4" Pipe)
(couldn't find a graph, but you get the point).

None of those AFR heads are even ported yet (quite affordable both before and after porting as well).

:gtfo:

Not just drag coefficient, frontal area. The Supra has a decent frontal area though.
Honestly though, drag area isn't a huge deal from a roll until over 150mph and most don't race that high.

Even then, it isn't a factor that more power can't solve.
For example, a Ford GT has a poor drag area, but still has the record for standing mile at 26Xmph (somewhere around that).

Exactly, and the supra holds the FR record for the standing mile with a high 25x.

No.

Ok, so lets go with the big boy 245cc heads you have posted above. Lets assume at least 7L of displacement (427). Then you take that little 3L from the Supra and its 183 cubes. The dyno record for a stock block/untouched head Supra is 1044RWHP. To make that number pertain to this conversation you would take the massive 427 and divide it by 183 and get 2.3333333333repeating. You take that number and multiply it by 1044 and you get 2436. So how many 245cc headed street cars you know of are pushing nearly 3000hp at the flywheel?

427/183=2.3333x1044=2436x.20=487.2+2436=2923.2 That would be the math at 20% power loss.

A 245cc head may have more CFM capability than the Supra head, but it doesn't have more velocity with all things equal. If the stock head of a Supra can push 1044rwhp and not bottleneck on 3L why can't the 245cc headed 427 push 2923rwhp at the same levels? Velocity over CFM any day in turbo applications.

Most may not race that high, but "most" don't have 200+mph standing mile street cars either. If you hit up TX2k11 you need to bring a 145+mph quarter mile car if you want to even stay in sight at times with the big swingers down there. As for frontal area, I left it out to keep it simple. The Viper has a large frontal area and it hits its wall around 200 or so. After that it has to use all of its literage to put up big numbers to pull on. Supra has a nicely balanced shape and shows it out there. Ford GT seems to be moving to the front of pack as it has a small frontal area and better than average aero for the event. Your correct about the Ford GT. The mph was 266.9 just so you know. Heffner ran it.

Exactly, and the supra holds the FR record for the standing mile with a high 25x.

Actually it is a Ford GT at 266.9mph as stated above.

He said FR record, as in Front engine Rear wheel drive.

As for the heads, there are several stock LSX headed cars with over 1000hp.
As you know, it's more about air flow and velocity than it is displacement.
If you're primary argument is head flow, then displacement is irrelevant.

Oh yeah, and two heads flow better than one.:P

Also quite frankly, you said head flow. That's the only issue I had with your post, and you built a straw man argument to knock down after your original statement got shot out of the sky. Ricer math is frowned upon here at LS1tech.

I didn't post any ricer math so leave the insults at the door. I simply showed you what the efficiency rate of the heads allow for when each is placed in direct and equal competition with one another. If a Viper head had the same volumetric efficiency as say a Type R head we would see a large amount of 2000hp Vipers running around, but it doesn't. Volumetric efficiency will never be ricer math. It is however scientific fact. Nothing wrong with that. I respect engineering. I 'm not very brand loyal as I look to whats out there, not always to what I own. I didn't see a straw man argument, I see an example of what a 2JZ head can do in stock form and what a 245cc head can do on the correct motor. You are very right in statements about which head has more volume and that two heads can flow better than one. But your missing the context of what those heads are designed to bolt to, which seemed obvious to me, but perhaps I should have elaborated on since that basic conceptualized idea is lost here. If the head is not the limitation of a 7.0L 245cc headed LSx motor, then what is? Those heads have a whole lot of volume obviously, but they need a 7.0L or larger displacement block to push the air through. Displacement is extremely important when determining what a head can do. You see larger CFM's on bench flow tests, but the numbers are irrelevant without the basic essentials the heads are built for. To much flow on a certain engine and you can't hold boost and to little on another and you end up with a bottleneck. The big 245cc heads need the extra displacement of the 7.0L to create the velocity needed for these heads to work properly. The Grand Canyon has an incredible amount of volume, but it has little velocity compared to say a jet engine. To make that relevant if you take the mass of air at any given point that passes between two points in the Grand Canyon and place that number againest a jet engine that is 2.3x smaller than the Grand Canyon pushing air at the same points, in theory they should both push the same amount of volume through. So which one is more efficient? The smaller jet engine as it can push the same volume through with less size. The 2JZ head has a higher volumetric efficiency than the 245cc head. The 245cc head has more volume than the 2JZ head. The more volumetric efficiency a head has the higher it can rev to. A stock 2JZ head will hit 9000rpms, with valve springs being its limitations, not flow. How many V8's you know of can achieve that? We can just choose to disagree.

Correct me if I'm wrong, but you said: "their heads in stock form outflow most of our high dollar heads." You weren't arguing volumetric efficiency, you only addressed flow capability. There are stock LSX heads that flow better than a stock 2JZ head.

You wanna look at a head with serious flow potential, look no further than ported Cobra B heads. Not C, B as in boy. They're efficient and flow well enough to power a car with a 4.6l to times quicker and faster than any 2JZ powered car.

I'm sure you had something important to say, but I didn't read it. Actually I lied, I read the first sentence, laughed, and then stopped reading. No insults anywhere in my post :thumb:

Here you go.
http://lmgtfy.com/?q=strawman+argument

You tried to say 2JZ heads flow better stock, better even than LSx high dollar heads

I posted information on the contrary

:Brace for Strawman:

Switch topic to volumetric efficiency (not something we were talking about...well, at least I wasn't lol). And back up with maths. It's very easy to beat up an argument that we weren't having in the first place haha

The head I care about is when it comes from the female brand..give it a rest..Everyone knows any LS1 vehicle is better than a supra..Even I would roll a lowly 2004 GTO before a supra..

Supras braker like their is no tomorrow.The guys usually have a boost leak or are on their third engine ect...The LS1's with an agressive head/cam set up are reliable 10 second cars
