FD vs C5 Corvette Z06
 

My '93 RX7 has a stock powertrain with the M2 Stage 3 upgrades (Large SMIC, Downpipe, remapped ECU, High Flow Cat, RB Duals, M2 Intake) and I run stock boost (10psi).

A couple times at track days (road courses, not drag)I noticed that my FD seems dead even with Z06s as far as acceleration in the straights. It kinda surprises me and some of my friends that I told.

Last night I encountered a Z06 on an empty section of the freeway. Usually I never race on the street but I was dying of curiousity to verify my track results. Plus you could tell the guy really wanted to race. So we did a run from about 90mph to 140mph. Fourth gear for me the whole time.

We were DEAD even. Side by side the whole time... maybe moving two or three feet back and forth at various points. Then we slowed down and we gave eachother a thumbs up before his exit. I think he was a bit surprised I kept up.

Anyway... I was surprised that the lighter weight of my FD was enough to counter the Z06s horsepower advantage.

Love my FD!

Good Kill, sounds like a fun race. Do you know if it was the older 385hp Z06 or the later model 405hp.. Just curious because the 405hp cars are noticably faster than the 385 cars.

hm, i wouldnt have expected you to stay even with him. Nothing against your car, just that its a zo6.

maybe it was the 385 hp Z06?


EDIT: as stated above

nice

Them Z06s are some bad MOFOs.

nice. kinda hard to believe, but i do.. also impressive since you're only at stock boost levels (10psi).

always been curious to how my car would compare to a c5 or z06. having similar mods than you, minus the hf cat, but running about 11psi, i should maybe be close to the speed of a z06.

I had no idea which model Z06 it was... could have been the 385hp or the 405hp version.

I have a feeling the nice torque of the Z06's V8 might mean I'd get smoked from a standing start though... who knows.

Prolly a 385 z06 with a bad driver. The 405 are not slow my any means. Not much heavier than the fd and very good gearing. Turn the boost up!

same results for me at the straights of vir...
im runnin 12psi with stock motor..turbos..intake.. ic....
full exhaust with pfc and pulllies at 2650lbs without driver...

Yeah my car weighs in at 2730lbs without driver so I have at least 400 or so pounds on the Z06.

Someone said he must have been a bad driver? How good of a driver do you have to be too keep your foot on the gas from 90mph to 140mph?

^^^ I was thinking the same thing, what he would've won the run if he hadn't answered his cell phone and drove into that tree?

John you should pony up for some dyno time, I'll bet your REW is running sweet.

EVERYONE knows a zo6 by either by the way the trunk is shaped (like a convertable but its a hard top), little air hole near back tire & the sticker near the front where our side marker yellow lights.


doesnt that sticker say how much hp it has??

Aside from the gear change, of course. 90-140 requires at least a 3-4 shift on a Z06.

That sounds about right to me. My friend has a '93 FD with intake, full exhaust, non sequential, FMIC, ECU, and has a weird boost problem where he starts at 8 lbs. and creeps up to 11. We did a couple races from a roll a month ago and he was right next to me. We raced a week ago and I pulled a car or two on him. I want him to get his boost problem fixed so I see how I stack up against the FD on 12 lbs. I drive an '02 Z06 btw.

thats funny! I wanna find a Z06 to see how my FD stacks up...lol
BTW, get it on vid and post it!
