BTW a stock 911turbo will pull on a stock viper. (not the new ones) the old gts & rt-10

A first gen viper but not a second gen or third gen.

Your intelligence and skillfull analysis are represented well by your spelling and punctuation :D

Why do you say that I suck at launching? Only an idiot would say something like that. You don't know anything about me. For all you know, I could be a professional race driver ........ which was not far from the truth a few years ago.

You should be more carefull what you write. No one will know how dumb you are until you show them.

BTW, in case you have not figured it out, this thread isn't about how you or I drive ;)

if the turbo 1st gens down here put a hurting on vipers and supras...im sure you can hold your own .

I'm not sure about the 993 turbo as I have no experience with them, but have had three lightly modified FDs and know four people with 996 tts both stock and modified as well as another with a Carrara GT.

In my experience if you manage to get a 996 tt Porsche owner to race you'll probably not have a hard time beating up on the type of driver which bogs a launch, shifts slow, and at too low of an RPM, but if you find a guy that can drive you're going to need some mods on an FD to beat the Porsche. Given alike drivers a 300ish wheel HP FD is about the same as a stock manual coupe 996 tt between 40 and 90 mph. Below that and above you're going to loose. You'll do best against the the slowest 996 tts which are triptronic(auto) Cabriolets(convertible) with a passenger and full tank of gas. The Porsche will be a good 4000 lbs and about as quick as a medium skill driver with a manual FD with cat back and down pipe.

A stock 996 tt driven to its potential is quicker than the highest modified 996 tt driven poorly.

The non-turbo Carrara GT is faster than the FD just about any way you look at it unless you're driving around with a three rotor and drag radials.

just for intrest sake what is the O-60 time for a 911TT or 966TT< what ever it is that your wanting to race? I have a friend who got his stock FD to do 0-60 in 5's and another friend with a moded FD with power FC and stock twins puching 15psi boost did 4.9's with a slipping clutch. This is just for interest sake here guys. I dont know shit about porche cars, Just want to learn. So would greatly apreciate the info on the car.

0 - 60 testing is expressed in two different ways. Testing is either done with a rollout or zero rollout. Generally if a rollout is used for testing it is around 12 inches before the time starts. The rollout would related to a shallow stage at the drag strip. It's good for a time discount of a couple tenths of a second. You'll notice in magazines some times seem better than what's expressed in another magazine. Most often it's because the lower time used a rollout. It seems to be the case that the popular method for 0 - X speed testing is with rollout. Assorted manufactures publish their data in both ways depending on who it is.

For high RPM launch with a good non-bog launch zero rollout 996 tt times are in the low 4 second range if done close to perfectly. A good driver might do ten runs and have three or four good passes. With rollout they are in the high 3s. The larger turbo 996 tts bog easier at launch and are quite difficult to get rolling. The X50 and S model stock 996tts have larger turbos than the base 996tt. Base 996tts with small turbos and computer flashes seem to have really good launches because of their quick spooling turbos. All this said It's not uncommon for an average driver to have 5+ second 0 - 60 times in any type of 996tt.

You're not likely to get a good 0 - 60 time in an FD if you have larger wheels with minimal sidewall street tires. Wheel hop sucks up time by requiring throttle modulation. A lightly modified FD is in the low 4 second range for a good pass having decent traction and minimal wheel hop. Most people are going to see 5 seconds and probably worse if you have a single turbo and street tires.

A stock FD on original wheels with original good condition Bridgestone S01 tires was capable of high 4s for the 0 - 60 with zero rollout.

Ofcourse he knew he was racing, that was the whole reason that we went out that night.

Hey thanks Greg. That was really good info. I dont have stock rims but i do have the stock tyre size of 17"x255/40 and 17"-235/45 and I dont get whell hop just spin. My best time with a Gtech was 6.2 its hard to find the right rpm to not spin to much and not bog. My car is still standard engine. Anyway thanks for the info. O and my view on this race, If you really want to know just race him from both aspects, rolling and stand still. Hey if you loose well then you learnt something. If you win even better. Cheers guys.

the porsche 911 turbo ill pull on these

a GT2 will pull on all these vipers & that fd of yours :bigthumb:

I love Porsche. Solely for the Carrera GT.

My god they hit the nail on the head with that car.

I dont know about that, go back a few pages....FD owned that GT2(again, i'm assuming thats the one with the turbo and not the GT3 n/a). It sounded real badass so it at least had aftermarket exhaust and who knows what else. FD in front from about 60 to 160...WHAT

Again, just go ahead and race this guy!!!

Wrong. I have a friend who owns BOTH and the Porsche isn't faster than his 2nd gen Viper.





Wrong again Bucky, not my fd.

Read this and that GT2 was modified and running over 500 hp. I also run 17/18 psi.

sheet or BS.

Whats so incredible about stock turbos pulling to 8k???? Mine do and theyre smokey...
If you what you really mean is the engine making peak power at 8k then thats a bit different. Most FDs with stock ports make peak hp @ 6500 rpms. With port work the peak hp goes up by about 500-1000 rpms. I dont think we can carry a flat curve to 8k though. In any case, just cause its German doesnt mean its the fastest thing out there...specially if you keep it stock or close to it.

Muhahaha! Yup, I need a rematch with him now that my car is tuned & running a little more boost (heck, I'll run him in the SLK!).

See ya,

I have raced four turbo 911s. The first was in a bone stock FD and he pulled on me hard although my friend with a 60-1 stayed right next to him. When we got to 145 he let off because he got scared so it doesn't count from then and basically he beat the crap out of me already. I also got smoked by 20 cars racing one in a stock automatic RX-8. I raced one in my T-78 FD while breaking in, I was on 10 psi (straight wastegate, 330 rwhp) a full tank of gas and a passenger. I was shifting at 7k for the sake of the motor and the guy beat me by 1 car (although it was a good race and he was shocked). Then I rolled one from a red light in the night time on 13 psi, I had a passenger and he didn't I beat the living crap out of him shifting at 8.5k. It was a newer twin turbo. I think 350 rwhp can give them a hell of a run no matter how good the driver is.

dont have scanner. give me a break. if u tune your car to 10.8 -11.0 then lean it alittle more near readline to 11.2-11.4 or so your power wont drop off far from peak.

If not the turbos, it could be just the engine pulling very good at 8k. Bone stock power does drop off at 7k but that improves considerably with only exhaust. Give the guy a break. My power drops off at 5k. hehe..,

agreeed!

for what it's worth. This is G-tech data.

This is testing for a stock 2003 996tt X50 and properly running FD with properly modified stock air box, down pipe, resonating mid pipe, HKS Carbon ti cat back, Power FC tuned to 11-12 psi, Supra fuel pump, light weight batery, low fuel, 19,000 original miles on stock engine, original turbos.

The below display is a Gs page display within a range of around 40 mph to 100 mph for a 996 tt X50, 996 tt with computer flash, lightly modified FD with stock turbos and engine and a stock 2003 Z06 Corvette

my bro did this race once... they were pretty close head to head almost all the way but at the end his fd won... the guy driving the porsche was an old guy and he came up to us and said... "DAMN, that shit is really fast!!!, I almost crapped my pants out there,"

The porsche was brand new and he had never raced it like that before....

911 tt awd weight 3800 lbs there pigs you have a great chance of winning

you'll loose from a stop & go (you wont catch up in time) but youll win from a roll (by half a car length depending on how far you go)

Where do you guys come up with this garbage?

The RX-7 would crush him from a stop or a roll.
