How much power does the FD need to beat a stock 2002 Z06 through the quarter (et and trapspeed)?

They run low 12's @114mph.....so you'll need around 340ish to the wheels.....all the bolt on's running 13psi...and you'll bust his ****!

320 RWp good driver.340 for sure.

Johnny

Do we really need this to be a damn poll......come on

I'm very tempted to turn it into a normal thread

JoeD

that would be a good idea. the voting will just keep on sending it to the top everytime.

NickSimcheck

I agree with Johnny.

I raced my buddy that had a z06, and beat him no problems.

a friend of mine went 12.44 bone stock, that is pretty fast. I would say you need 340 or 360 with a good driver.

ttpowerd

hmm....340 would be a safe bet

Bucrx7

I'll say 340 with a good driver.

If you use ratio 405HP/3300lbs-assuming FD 2800lbs
HP wise @ 340, but the Vette has a lot of torque to get it in motion.

I believe the new Z06 weights just 3120lbs.

If you use the ratio "theory", the 2002 ZO6 is making 405HP at the crank ... guestimate about 370HP to the wheels ... then, the 2800-lb ReX would have to make about 330 RWHP just to match the ZO6. Now, since the ZO6 generates tons of low-end torque, it's gonna be a LOT quicker off the line. To beat a ZO6, I'm thinking more along the lines of 370-390 RWHP, which means you'll need to be making 400+ HP at the shaft.

If you do a search about making 400+ HP, you'll find that it's gonna take a lot of work (translation = $$$$$$$$$$) to make your FD pump out that much power. And BTW, the ZO6 is very adept at the twisties as well ... so, the whole cornering bit is out-to-lunch. From my limited experience, I still have a tough time with regular ol' LT1 Corvettes. A ZO6 would be no contest ... he wins.

Considering that I only have around 280rwhp and I beat a regular new vette, I figure between 320 and 335, at most, those vette arent as fast as what you think

jimlab

You beat a 3,300 lb. Corvette with 350 horsepower and an automatic transmission, more than likely.

My 2002 Z06 is 3,115 lbs., is making about 415 horsepower bone stock, right down to the GM paper intake filter. There is now at least one '02 Z06 into the 11s in completely stock form, and more than 15 into the 11s with just a cold air intake, all on stock Goodyear rubber. When was the last time you saw an RX-7 run an 11 without slicks? I still haven't.

A stock 2002 Z06 ran these times at Ennis on 2/11...

60' - 1.915
330 - 5.130
1/8 - 7.777
mph - 93.56
1000 - 10.055
1/4 - 11.992
mph - 114.73

60' - 1.852
330 - 5.055
1/8 - 7.709
mph - 93.32
1000 - 9.992
1/4 - 11.933
mph - 114.53

Jim, I'm not surprised at the 114mph, but I'm really surprised at the 11.9 et. Those Goodyears must be like slicks and that guy knew how to drag race. Amazing time. I would have expected maybe 12.3 at best.

That's pretty impressive, but judging by those trap speeds the guy was slipping the clutch and powershifting like crazy. Most RX-7s that I have seen in the high 11s are running close to 120 in the traps. I think its great that a stock car can be made to run 11s, but i wouldn't want to blow out my clutch and tranny in a few thousand miles in order to do so.

Peace

jimlab

That's true for the RX-7, but the Corvette's 115 mph trap speeds are typical for a naturally aspirated engine that has a more linear power curve.

A turbo car (or nitrous, for that matter) will accelerate radically at some point on the track. It may run a slower E.T. because it doesn't get off the line as quickly unless you're able to build boost on the line, but once the turbo(s) spool, it'll cover the last portion of the quarter very quickly and the result is a very high trap speed. I've seen a lot of RX-7s run 117-118 mph trap speeds. On 13.1-13.8 passes...

Believe what you want, but the transmission was in no danger. The clutch is stronger than an RX-7's, and the T56 6-speed transaxle will take far, far more punishment than an RX-7's 5-speed. Here's another Corvette with the same drivetrain, and you should be able to tell that he's not hammering his shifts...

Just suppose that you do modify your FD enough to beat up on a stock Z06.

How about a modded Z06? Isn't is more fair to race against a modded Z06? Who cares about fair anyway, right? It is all pointless anyway.

Add more money and know-how to car X and it will be faster than car Y (all else being equal).

Or why not make it interesting and do some dial-in dragging and see who the better drivers are?

artguy

the last time i was at the track the stock Z06 I saw ran a best 13.1 his previous numbers were 13.2 and a 13.3.

I still havent seen one run in the 11s.

I think you're missing the point. It's common knowledge that a stock Z06 is faster than a stock RX-7. And as far as modded vs. modded, well that MTI monster Z06 is prove enough that a modded Z06 is still faster than a modded RX-7.

Average market price for a say '93 RX-7 is about what ... $13K? Sticker for a 2002 Z06 is something like $49K? You do the math ...

I would love to own a new Z06. I simply don't have that kind of cash. However, it's not outside of my wallet to save up $10K to make my RX-7 faster than a stock Z06.

Johnny

Sorry closing Poll version....
you are still welcome to comment...

jimlab

Sounds like you watched a C5 or a poor driver, or both.

All of the "Z06" parts (wheels, red calipers, brake vents, fender badges) are available aftermarket, so you can make any Corvette into a "Z06".

And then of course, there are people who just can't drive, or who lack the experience to get a good time out of their car. The trap speed should be a good indicator of whether or not the car is legitimate, though. A true Z06 should post a 112-114+ mph trap speed regardless, unless the driver misses a shift.

Finally, there are two "versions". The 2001 cars have 20 less horsepower and 15 less ft. lbs. of torque (385/385 vs 405/400) than the 2002 models.

You hit the nail on the head, redrotorR1. The reason I started this thread is that I wanted to know what it would take to bring my humble RX-7 up to the performance level of a Z06. I have tremendous respect for the Z, and it is one of my dream cars. However, I will not be in a position to buy one until Fall at the very earliest, even if I chose to go with the Z.

In the meantime, it would be fun to mod my RX-7 so that it can run with the nastiest Vette ever. I just dropped a street ported, 3mm apex seal motor in my RX-7. It's still too fresh to dyno, but I'm hoping I can hit that 340rwhp number. My performance mods include Power FC (tuned by SR), intake, Y pipe, downpipe, midpipe, catback, PFS intercooler, 20B fuel pump, and pulleys. If that's not enough, maybe T78?

My car's pretty respectable in the corners too, with Koni Sports, PFS springs and anti-roll bars, Unobtanium bushings, and M2 trailing arms and toe links.

Once the motor is broken, I hope to be able put up a good fight against the Z06.

waltk88

jimlab, any run-ins with RX-7s in the Z06?
