the cheatr can will NOT sound 100% stock, it will have some lope that anyone will detect. I've done the exact same thing you are wanting to do and my car runs quite well despite almost being 3500# now (due to dynamat). I have an 00 C5 Vert w/ z06 manifolds, h pipe and a 2000 cat back. Car is dead silent but at idle is has a very slight lope to it you can and will notice. I tried to up the idle some to 900 and it just sounds like the car is racing a bit and people will suspect something. My car looks 100% stock and is well into the 11s w/ an ls1 intake still and ls6 exhaust manifolds (Same as ls1 anyway)

hmm, sounds like maybe the only choice is an LPE GT2-3. I'm pretty sure that has no lope to it.

**** it, LPEGT2-3, 125 Dry shot. Bring the cobras Should run 130mph in the quarter.

Sounds like a plan, just keep in mind that GT2-3 will only gain you about 10rwhp on your 02 Z06. Even Ed @ LPE said this, so it might not be worth the expense if you are going to do N20 anyway. If you are buying new and having a shop doing the install, not sure if you could justify the expense for 10hp, but if you will do the work yourself, maybe its worth it to you. Also, I heard someone say that the 02+ Z06 cams like N20....not sure why, but thats what I heard...

Jessel roller rockers will go along way towards keeping the valve train noise down and will allow you to turn more rpms.

A Vararam and 315 BFGs got my time below, and self tuned. Blows away all the Cobras around hear. Then if someone has a highly modded Kenne Bell Cobra or something similar, it's time for one stage, two stages or throw the thrid stage of n2o in the mix. Stock cobras are slugs compared to the Z06, so maybe some more seat time is all you need. If your going up against a highly modded Cobra, why can't you be modded. You cheat someone on purpose in my area and you'll get what's coming to ya, for sure. If you have to cheat, stay the hell home with your mother.

Hey Robert, I just bought a Vararam for my 01' Z. Did you have to get the car tuned after adding the vram? What type of gains did the Vram give you? Also, when you say 315's do you use 17's at the track, or is that 315's on the stock Z06 18's? What are they like 315/30's??

PS-I am "kbreese" over on the corvette forum.

No in the beginning I just let the computer do a relearn. Your long term fuel trims can compansate upto about 25% lean or rich. But for ultimate performance you will need to tune your ltft and MAF. The reason being is with the Vararam you'll see postive ltft, meaning computer is adding fuel for a lean condition (Vararam is flowing more air) which is ok, computer is taking car of it, except when going WOT. At wot the computer freezes positive ltft (say 10/15%) and adds this additional fuel to your WOT Power Enrichment Multipier, so you end up running pretty rich at full throttle only, killing some power. If your ltft is in the neg percent they are dropped at wot. This is why when tunning ltft we try to get them in the neg area a bit, then thay have no effect on wot performance. the gains are the time in my sig for stock CAI/DR after a self tune.
I run the 315 30 18 BFG on stock Z06 10.5 wheels, new style. Old style you can get in 315 35 17 and tread compound is similar.

So even after the computer relearns the addition of the vram, it will still run very rich at WOT? So essentially the car could actually run slower with the addition of the vram and not getting a tune, ever after the computer relearns?

Where I am at is I have a vram right now, and plan on getting LT's eventually but not sure when that will be. Might not be till spring. I don't want to pay for a dyno tune until I get the LT's on, b/c I don't want to pay twice. So I am wondering if its even worth it to put the vram on now.

get gears and nittos.. they will impove your 1/4 more than the above mods.

No it won't run slower, you will see gains, however, for optimum performance a re-tune is in order. yes, it will be a little richer at wot throttle, but gains will be there. I would put it on and then wait for LT for a dyno tune. Some see lean codes at first, but just reset, and after 100/200 miles computer will make adjustments as far as it can. I never threw a code, mostly it seems to be the '04's which came wwith a slightly leaner tune than previous years.

I'm going to make my firebird a sleeper with Nitro Dave's "Money Maker." Maybe, if you don't mind a hidden direct port nitrous system, you'll do the same?

P.S. I have no idea how I found this thread.

I have done many bone stock Zo6's with a small dry shot of gas (125hp) and 275/40/17 ET Streets on Z06 Front rims sleeper and this is how you do it Stock they ran 12.2 and made 354 rwhp flip the switch and you have 454 rwhp 11.10 @126 1.7 60"... I have made a lot money on these Vettes. Look, sound and run bone stock ha ha flip the switch and take the money!
