I found the vid of my 1999 intake and no cats 430 rwhp Viper against the 408 ci 480 rwhp ws6..

like i said the 390-440 rwhp H/C fbodies ive raced were never a problem what so ever...And as you can see even this 480 rwhp/460 TQ 408 ci ws6 had it's hands full...


http://www.streetfire.net/video/bird...-st_101284.htm


in comparison when i raced a stock Z06 with this same 430 rwhp 99 Viper he pulled 2-3 carsd every time..

Fbodies have quite a bit of weight at 3500 plus pounds...And at only low 400's for TQ with H/C they have a hard time matching the 3380 plus pound Vipers..

And then compared to the Z06's 3100 plus pounds..WOW..just an uphill battle..


This is all from a roll though..At the drag strip the fbody just does insanely well...especially the stalled h/C autos...

Anybody else find it funny how not a single LS2 has breached the 500rwhp mark yet, even with fully ported L92 heads, yet dozens of LS1 guys claim to be 450+rwhp with ported LS2 heads? Is it just me, am I missing something?

Now these runs where based off the runs I've had against my cousins car with the exception of one other race. I am willing to prove my point on video from a dig and from a roll. I am in the process of replacing my tranny at the moment but once it is finished if any one in the New Orleans area wants to race a H/C/I 3600lbs Z28 A3 with there bone stock C6Z06 we can get it on video. I know my car isn't the badest car on earth but I also know what it is capable of.

no ones doubting the 1/4 mile stuff bro...it's just street and roll raceing ( that this section is pretty much dedicated to) that we are talking about...

lets say your H/C/I auto Fbody can trapp 122 in the 1/4 mile..On an auto Fbody this would be good for low 11's all day long and you will destroy Z06's vipers GTR's and even run neck to neck with ZR1's..

But from a roll the only car you would have a chance against is the stock 96-99 Vipers and maybe the 2003-2006 Viper..And GTR

the C6Z06...08 Viper...ZR1 will all just walk away above 120 mph...

i mean honestly when you really think about it...does it really matter though..
ive seen enough vids to know that from 0-100 mph a Z06 and 08 viper and ZR1 are all dead even..sure from 120-150 the Viper will put 2-3 cars on the Z06 and from 120-150 the ZR1 will put 2-3 cars on the Viper...

But from 0-100 they would all be a tie....most of us dont exceed 100 mph very often..

So in this case your car can probally match them from 0-100 mph...

So I guess I see what you are saying..be interesting to see what yours can do once you get the trannie back in

Whats a stock viper trap?

you know a stock C6 Z06 traps 125-127 bone stock... some even did 128/129/and 130 Z06s stock run low 11s with good driver even on the stock runcrap tires. best stock ET was a 10.9@128 and stock with the exception of drag radials, 10.7@129!! the key is "Good Driver"

at you guys talking Rwhp... I make 370Rwhp and knocking on 10s doors, the number means nothing if the combo doesn't work. You can have a "low" Rwhp car setup right and run good.
From a roll..... It would take a perfectly set up fbody M6 with weight taken out to beat/be even with one IMO... You have to think, they trap mid 120s or so... Not to mention that 427 doesn't lose steam up top.

12.8 is that his best run!!!? I ran 12.5@118 bone stock with shitty 60ft (2.2) and easy shifting at a 7000+ DA ..... again key is good driver and practice!!

and just so that you know, this was my first time ever to go to a drag strip and it was less than a week since I got the car!! and only did three runs as the car was running lean and my coolant water was leaking.... best trap speed that day was 119 I believe, and best 60ft was a 2.0X, but as you can see in the vid lost it on sec gear. so I decided on my last run to easy shift! I should have lowered my tire pressure to 20 or 18... but again i was still new in that car and didn't know I will only do three runs

Like I said man, from a 40mph hit I would pull about a car to a car in a half on him. He would stop my pull by 80-90mph and slowly start to come around me at about 120mph. This is not hear say. This is what happened. Like I said before, as soon as I get my new transmission installed I will gladly run a stock C6 Z06 vette to prove my point.

Where the hell are you getting your info? There are more 500rwhp LS2's than there are 500rwhp LS1's.

For the OP, ask align_c5. He was putting down 495 rwhp in his c5, and kept getting beat by a stock Z06 from rolls.

Basically it comes down to a driver's race.. are they willing to shift their vette where it needs to be and not short shifting?

I totally understand, I was just saying facts. im not saying you did or you didn't beat that guy... as street racing has many factors....... I dont care what people say, but any car that beats a Z06 is a fast car! very nice man, hope you get your tranny back in and find a stock z06 that will play

There is nothing wrong with the tranny in the car now except for the fact that it is a 4L60E and it lags through every shift!! LOL I am in the process of swapping it out for a th350 and installing my suspension. We are expecting to pick up 2-3 tenths and 2-4 mph swapping to this tranny. So that would put me at 125-127mph. I am also building a 402ci LS2 hoping to run 135+mph on the motor and close to 140+ on the spray.

my buddy put down 480whp on his LS2 GTO with a street setup and safe tune....

he was able to hit 500+whp, but drive-ability was more important for him. and many c6s did hit 500+whp

That would be FUN FAST CAR

Oh really? I got most of my info from the L92 headswap post on LS1GTO.com
http://www.ls1gto.com/forums/showthread.php?t=286447

The only guy who supposedly broke 500rwhp was Ed at Virginia Speed: his clutch went out on the dyno but he claimed to make over 500rwhp before it gave up the ghost. He was going to post it up to take the top spot on the L92 head swap boards after he replaced the clutch and re-ran it. He never came back though, so I'm thinking he couldnt replicate it.

Also VAS at Complete Street tried and failed: So did the guys at Texas Speed, and even Formato's shop had a hand at the list: all either built customer cars aimed at taking top spot on the list, or built there own to do it. Still nothing higher than this:
PhillyGoat 486/435 M6 232/238 .595/.605 114

Requirements to be on the list is a stock bottom end. Thats it.

I've heard of guys with AFR 235's ported out and a nicely match big bumpstick hitting 500+rwhp, but if I didn't see the dyno graph, and it was a "so and so has 5xxrwhp..." thing.

Not saying it aint true though! What the hell do I know, I'm just a bolton noob: So where do I find these LS3/L92 headed LS2 guys to learn what combo worked for them?

I dont really want to get into this... but ive seen some people over the corvette forum claiming 500whp on LS2 c6s with heads/cam/intake/ and boltons

and when I said many c6s I kinda meant all LS2 and LS3 c6s probably forgot we were talking about LS2s only lol but again ive seen some people claiming 500whp! and ive seen some around 480whp with stock intake so with a 102 fast, they will probably hit that 500+whp but again its all about the tune and combo!!

for me dyno numbers dont really matter that much and they are not really that accurate!

Thanks for the info. Goal for my car is to trap 120-124.

480rwhp is pretty outstanding for 2.5 heads. Thing sounds mean as all hell!
