how much rwhp would it take in a '99 ws6 6speed to beat a 02 zo6? everything being equal except for horsepower and weight.

FLYNLO

I think that is an interesting question. How much HP does it take to get a trapspeed around 115mph or so(with a 6sp)? Sorry to answer your question with a question but it may be another way to look at it. I honestly don't think it would take much more RWHP on an F-body than what the ZO6 has. There is a fellow member here who has a 370rwhp SS that we have been trying to get together and race just for a comparo. Hasn't happened yet. Will let ya know if it does. I think it should be very close.

friend of mine has gone mid 112's with just a lid and catback 02 m6 z. only weight reduction being jack and spare. im sure with headers hed be at 115 or more. id imagine 350rwhp with more traction than the z06 would probably be enough depending on how long the race is (aerodynamics being better for the vette) and how good the z06 driver is.

Most '02 Z06's I've seen trap right around 112-114 mph and most M6 F-bodies I've seen trap around 105-107 mph. So I'm estimating it takes a f-body around an extra 50-60 rwhp to hit the same mph as the Z06, if the f-body is not lightened or has different gearing.

FLYNLO

LEO, not disagreeing with anything else in your post but even the lame *** magazine drivers are getting a solid 114-115 out of a ZO6(my lame *** driving included). And with traction(tires), the ZO6 is in the 11s(assuming a fairly decent driver).

I am about 2-3mph slower if not lower than that in my 00 Hardtop with B&Bs, but then again I got one of them factory freaks.

I dont know if you're a budget guy like myself, but for 5bills you could get an easy to install 100 dry shot, that should be enough not to need to worry, figger your still 30k behind but have a faster car, lol

BayouVette

Everyone is talkin about trap speeds.. The Z06 gearing and tranny launches hard. They get to those trap speeds a lot faster because of the takeoff. I dont think judging it by trap speed is a good comparison. I could def. be wrong though..

NIRVANA

BayouVette, you're definitely not wrong. Asking how much RWHP needed isn't the right question to be asking. The question is: What can I do to get my F-body through the quarter mile in about 12.5 seconds? The reason it's a bad question is because you can do many things to an F-body that would have no effect on horsepower, but would drastically lower your e.t.'s. For instance you could install a better shifter (if manual), sticky tires, smaller gear, etc. and probably hang with a Z06. Hope this helps.

FLYNLO

All good points, Adam. I almost included ET in my answer but that isn't really an indication of power.....usually trap speed is a good indicator. For example, a Bolt on A4 LS1(maybe in the 330rwhp range) with stall and gears is possible good for a mid 12s slip.....but the trapspeed would probably be around 107ish....meaning he gained everything on the launch. This same car fom a roll would get smoked by a ZO6. SO therein lies another question....how do you like to race and how are you trying to beat the ZO6 in question?
Just a little FYI...ZO6 ain't all that easy to launch as had been said a few times. My best is a 1.95 which yielded my best time. There are people that are well into the 1.8xs but that is about where it will end for the stock tires. Then there is J-rod with a basically stock car(zip tie mod only) on ET streets doing 1.5x and 11.5xx....the dude can drive.

Adam, read what i wrote..."everything being equal"...i heard of zo6's running 11.6-11.7 on drag radials and a cold air induction setup. NO GEARS. both cars right off the showroom floor, how much more RWHP is the T/A gonna need to hang with the z06. the T/A is a 6 speed= no stall convertor.

VTtransam

In an M6:

Get all the bolt ons including headers, etc... That should put you around 355rwhp?? in a fbody.

Z06's dyno right around 350+rwhp stock correct? Toss a small cam in your fbody for about 375rwhp, maybe some 3.73's and You should best a stock Z06 pretty consistantly. Fbodies have a huge weight disadvantage compared to a Z06.

Or you could pass on the small cam, not eat for a week, and make sure the Z06 has a 300 pounder riding shotgun, that should be pretty close.

Either way you go about it, those Z06's are sweet. Damn all of you that own one!!

I see. I guess I misunderstood what you were saying. I guess in order to answer that, somebody who has a TA with a 6 speed (with only HP adding mods) that has beaten a stock Z06 would have to reply and tell us their dyno #'s.

only one mod I would say CAM!
I would murder z06's with bolt ons and a 100 shot. But with bolt on and a cam I had the numbers below and pulled a 02 z06 a while back by 1-2 cars from 1-3 gear

I agree with wicked.
Z06's are very quick cars right out of the showroom, and as FLYNLO said the race depends alot on the driver of the Z06.

I also agree that the question is a bad question. There are way too many varibles to consider when racing a car that is much lighter, has a completely different rear setup, and is also much more aerodynamic.

Personally, I would say that you would need to bring an M6 car up to the 375-400rw hp range in order to consistantly beat a stock Z06. The reason why I guestimate alittle higher then the others is due to the fact that most Z06's stock put down around 360 rw, and then are much lighter and more aerodynamic.
Also as it has been said by others, a stock Z06 can run anywhere from mid-high 11's, to mid-high 12's. If you race the driver thats putting down high 12's, you wont need much more hp then you currently have. However, if you find the excellent driver that can push that car to high 11's, you will need at least 380 rw to get you to run even with him. Add 20 or so rwhp just to be on the safe side, which puts you around 400rw.

Head/cam .... cam and nitrous ... full bolt ons and big cam. Any of these would be quick ways to get to 400 hp, and not have any problems with the Z06.

In theory, 100lbs = 10 rwhp. So if a specific ZO6 has ~250lb weight advantage then you need to be putting out ~ 25rwhp MORE than that ZO6 to compare. If your average stock ZO6 makes 355 rwhp, then you need to be making 380rwhp minimum to match trap speeds. Again, this is just the dreaded "everything else being equal" argument so your results may vary, but it should be reasonably close.

Do you concur? Yes I concur.
Do you also concur doctor? I concur.

Then let it be written.

OK, I have 2000 M6 with the mods listed below. I dynoed at 365 rwhp and 372rwtq. My car is at full weight (I weigh 165). I raced a Z06 on the highway from 70 to about 130. (I dropped it to third gear at 70) I got ahead of him...


How much torque do they put down?

Some stock Z06 dynoes:

Wow, I have never seen a Z06 dyno that low, all the ones I have seen were in the 345+ range.

Those torque numbers are really low also.
