2002_TAWS6

Post is long but Please READ!

Ok Im planning on going with H/C setup. Heres what I had in mind:

Car: 2002 Trans Am WS6 6-spd

Mods:
-Stage 1.5 TEA heads
-Thunder racing cam: 224/224 .561/.561 114 LSA (STEALTHY CAM)
-KOOKs LT 1 3/4" headers with 3" ORY-pipe (NO CATS)
-Direct flow Air lid
-Corsa Exhaust (NO CUT OUTS)
-Spec 3 clutch
-Stock rear (lets just hope it will hold up or ill have to go for the 8.8 rear)
-Tuning ofcourse
-MTI Underdrive pulleys
-Spec 3 clutch and BILLET flywheel
-Nittos 275s (going on stock 9" wheel)
-LS6 intake manifold (dont forget we get those on 01-02s)
-everything else STOCK. No gears no suspension mods no nothing just the mods above.

This setup should dyno 420-430 rwhp and 400-409 rwtq. With quarter mile times in the very high 11s remember I said NITTO DRs 275 for the tires in the back. Tires in the front will be the stock 275 goodyears and all tires are going on stock 17" 02 WS6 wheels. This post is about these tires ONLY so dont mention anything else! )

With this setup would I be able to beat:

Car: 2002-2004 Corvette Z06
mods: Just nittos

Now I know Z06s run mid 12s in the 1/4 mile but I heard 11.9s or faster are definetly possible with 120mph trap speeds if they use Nittos as well!

How would my car (with mods on top) run with the Z06 listed above?

Please mention 1/4 mile comparison AND a 40mph roll all the way to 160mph!

Dont be biased on your responses as I want to know what to expect after a $6000 investment!

I had a similar post like this one early but I forgot to mention that the Z06 will be using a pair of nittos for the back as well!

I used to think 420-430 rwhp would be more than enough to beat a 360rwhp 02 Z06 but now that I heard how they run with nittos (just so we can both be fair) Im worried.

I also thought with that much power I would be able to beat a 01-02 Porsche 450hp (NOT RWHP) 911 turbo from a 40mph roll (all the way up to 160mph). Was I living in dreamland when I thought that? Or will I be living the dreamland with the future setup

Car will not visit the 1/4 mile track so often. I would be interested about the 40mph roll street race over the 1/4 mile numbers but if I know both it wouldnt hurt

help help help before I spend a lot of money and cry when I lose!

On the street, anything can happen. Track, it'll be up to traction.

I'd say it's more or less the driver's race.

I think it will def. come down to driver vs. driver. You have more power but the z06 is much lighter. Good luck man.

With weight reduction and just a cammed LS1 with your bolt on's I think you can beat a Zo6,but with out suspention upgrades and your mods,even with DR's I think you'll have a hard time hooking up. Just my experience, Good luck.

I hope your not talking about a stock 911 turbo. Cuz they didnt come with 450Hp, more like 415 or so. The GT2, has 456HP though. If its not stock, what did the guy do to it? Just curious, as those engines are hard to do much to, as Porsche already tweaked and tuned the hell out of them.

2002_TAWS6

new ones come 450 not at the rear wheels though

I think the general rule is that it takes an f'bod approximately 400 rwhp (somewhat on the safe side) to beat a stock Z06 from a dig. Since you both have nitto's, traction shouldn't be too much of an issue for either of you. I would say if your setup gets you over 400, you should take him with relative ease.
From a roll, you should take him pretty easy as the lower weight will not play as large of a part.

I'm not as sure with the porshe, as I have never raced a "new" one ... but I am sure it would be a very close race, that you could definately end up winning if your drive well.

Careful with Turbo Porches. Actually lined up with a GT2, results were pretty ugly

With a good driver a Z06 can run 12 ohs.I have done it in my 700 miles old 03(see sig). I think you would be at a disadvantage against a Z from a roll due to the top end charge of a LS6 and aerodynamics.A F-body has the advantage on the launch with the solid axle.Driver ability will determine the winner,should be close if they both can grab gears.

Now, Im not trying to be a dick or anything, but I was pretty sure that the turbos dont have 450HP. This is the actual porsche web-site, so, it is credible. Though, this is for the Newest model. Perhaps I didnt know about a 450HP version in 01-02? Though, I am 90% positive there wasnt.

well since the Z is in the 3200 lb range, you will have to factor it in. beyond that, it is drivers race, and who can grab traction at the line. that is all the race is going to come down too. good luck, but who cares about stealth!! J/K good luck with your setup. there is someone on here was it you 422 SS who is trying for the 11.9s with no mods, and you just hit like a 12.001 not to recently??

You gotta becareful with that as well. I know there is another Porche running around here with a turbo and sent it off to get upgrades. The guy is running mid 12's here. For reference I ran a 14.3 completely stock. The average DA in the summer runs between 7000-8000ft and the track has been GPS'd at 5380ft elevation. You can imagine thats pretty quick for our altitude.

There is an actual posse of these guys. They can afford the good stuff and soup them up to Damn old farts

That cam is the same one I've been looking at. I've been told that a setup similar to the one you are describing performs great on the street. I think from a stop you should be able to edge out the vette. Like they said though it's a pretty even matchup and you are going to have to rely on your driving skills. It would be especially close at the track after you do minor weight reduction. Most drivers out there arent good enough to cut 12.0s in a bone stock vette but there are quit a few I'm sure that can. Under ideal conditions it would be a very close race but on the street from a stop I think the fbody would have an advantage.

The reason it typically takes an f-body around 400+ rwhp to keep up with a Z06 is that they are much lighter and they have a different tranny with lower gears. I think the gearing equates to about a 3:90 rear differential.
There have been drivers with slicks running high 11s bone stock. The Z06 is stout bone stock, with some bolt ons they really get quick, and if you do cam and exhaust, they can easily dyno 420 rwhp without head work.
So you could beat a STOCK Z06 with your 420 rwhp car if you don't make any driving errors. Although gears would help ensure a victory, you would probably be buying a 12 bolt real soon. If you can drop weight, that would be a big help as well.

Z06 weighs 3020 I'm 240 = 3260 raceweight.Ya that was me with the 12.0.I think I could get a 11.8 stock with more practice and better weather.J-Rod has went something like 11.60 in Houston with a basically stock Z.I plan on H/C longtubes and 4.10s this winter to get in the 10's.

Wow 422 SS

Thats awesome. What did J-Rod do? Slicks and 6600rpm clutch drop?

What do full bolton ZO6's run?

By bolt on I mean

-LT's no CATS
-Vararam intake
-Ported TB
-Tuning
-4.10's
-Slicks/skinnies

from my understanding the first 3 gears are great for dragracing but the 4th gear spread actually bogs down the car a bit. Whats your take on that?

10.5 Dave

iTrader: (5)

I dumped at 6k.I didnt notice any hesitation after the 3/4 powershift.I only have maybe 25 passes in the car and havent driven a 6sp at the track in a year.I know I could run faster but up north the tracks are closed for the winter.If I was in the deep south in the winter I think a 11.7 is possible.

Vendetta

Yeah, tell me about it

BigBronco

thank you houston for being at sea level, and being open all year, or at least almost all year!! definately 11's are possible, and sorry with the weight, i though it was 3200 cause the weights i did see were with driver weighed inside. forgot about that!

2002_TAWS6

So I take it even after $6000 in those mods a stock 02 Z06 will still beat me from a roll?

If thats true it would truely suck since at some point of time i'd be 60rwhp OVER his rwhp. Weight cant really be the big factor here as 60rwhp over (even if that occasion would only be at an instant) should still make the f-body run quicker? Maybe its the gears? Maybe its the aerodynamics?

Whats wrong here cant seem to understand. At first I thought I had more hope from a roll as putting the power to the ground would be easier for me then doing that from the start??

MillaTK, the 911 turbo link you posted was like the Z28 version of the Camaro. Heres the SS version of the Porsche that you could get from the Porsche Dealership :

If I find the an official porsche website ill post the link. Im sure its out there though.
