I mean with 400+whp, not stock. Stock, I really liked the gearing, but then, I am used to American cars which are traditionally geared taller.

even for a 400whp vehicle i still feel the gearing is bit too tall for my liking. you should try a 400whp sti or evo

it only takes a blink of an eye to run out of 8000rpm in 3rd...

however, american cars do have very very tall gearing. i can see why you are aren't used to it.

All that shifting slows you down. I don't like it.

cant really agree with you there.

greddy tt, osg clutch, greddy exhaust. fuel pump and injectors. reflash. volks and re11's.

have yet to run into a vette that can pull away. there was one decently modified c6 z06 that seemed dead even from many pulls. but a stock one doesnt stand a chance.

there is nothing about the vette that gives it much a traction advantage at all... the transmission is mounted a couple feet back, thats it. Otherwise its all in setup. Most 370z owners will have insanely stiff coilovers at the very least, limiting weight transfer to almost nothing. most of them will use those coilovers to slam the car to the ground and have far too much negative camber and ride on half the tire.

but if setup correctly and using some good 305 or 335 tires, i cant imagine anything about a modern corvette that is going to give it any more traction for the power.

and if we are just talking about taking down a base model vette with typical bolt ons... thats not even a challenge for a TT'd 370z... i imagine i could turn off the boost controller and run my wastegate springs 5.5psi and have no trouble with one of those. the only stock or bolt on vette that is going to beat up on a TT 370z is a ZR1

I have yet to see/hear of a TT 370Z on street tires that can go WOT in first gear without plastering the pavement with rubber.

What makes you think that a vette with the same power, using the same tires with the same alignment specs and similar spring rates and shock dampening is going to hook up in first? It's not. Don't tell me a bolt on c6 z06 can't spin tire in first without dumping the clutch. If your vette can't... Might want to take it in for some warranty work

It can if you stab the throttle, but I can roll into it from a 5mph roll and be WOT and it holds just fine.

Ya the gearing feels very tall to me as well, but I'm also only running a lightly Modded Z.

ImPoConVo loves talking out of his azz. Don't pay him much attention and he'll go away...well hopefully.

Cheese with that?

phunk · 10-27-2011, 11:27 PM

Nobody is going to put 500 to the ground in first unless they are serious about doing that and willing to sacrifice in other departments. The Z doesn't attract drag racers so it's very rare someone that owns one is dedicated to setting the car up for that and willing to let go of their 19" wheels and coilovers that might as well be solid bars and ridiculous alignment specs. But if someone was in the drag racing mindset when making their decisions for all of the car and not just the making HP part, there is nothing stopping a Z from putting power down any more than a vette. Especially with a 370 since they can fit 335 tires without cutting just like cars meant to make power do

Very cool that the 370 can take that much tire. Ford could learn a thing or two about designing the next gen mustang from that. Other than rims, anything need to be done for the 370 to accept the rubber?

I'll let you know in spring. The best I can say is that my 305s fit with a bit of room on the inside, then I spaced them out another 15mm. I am very confident nothing will have to be done with the right offset for the camber setting. But others have already done it

Nice. I am curious how well it hooks up on street tires, if the short wheel-base will allow for more rapid weight transfer, etc.

It's only 5" shorter. Again, weight transfer is all in the setup, it won't improve unless I go soft on the suspension ... Which I don't think I'll need to for stock bottom end power levels
