I have 548 rwhp twin turbo setup and from a dig my fathers lingenfelter supercharged z06 running 575 rwhp pulls away from me and i cant catch him mostly because we run out of track or road when we turning 150mph but if we take off at 60 i run him down every time. His car has gobs of torgue at the bottom end of the rpm range but once im reved up that z comes alive.

I always wished for taller gearing in my STi. When you have boost, you don't want to get out of it with a gear shift. With that car I had to shift from first to 5th gear in about 8 seconds under WOT. Pain in the ***.

id like to swap down to the 3.3 pumpkin but i dont know if i want to deal with the SRM problems
|
3.3 would be nice.
|
Its definitely doable, and losing the SRM isnt making a sacrifice versus other cars, but it is one of the cool features that currently only the 370z has, I would prefer to keep it. But shifting out of first at 42mph is sort of low for a 500+ rwhp car. the 3.3 would bring it to 48mph i think, which isnt even a huge difference, but if we raised the RPM to 8000, that would get us to 51mph... which is totally reasonable and doesnt cost us more torque in each gear like a further drop in rear end ratio would.
i wonder if anyone is revving these VHR heads to 8000 yet to see how they hold up? |
I don't think they are FI'ed but there are atleast two that have rised the rev limiter to 8k. One in japan and one in the states.
|
that sounds like a good idea. raise the red line would be pretty sick all in itself.
|
Yeah, SRM is one of the reasons I am insisting on the sports package. As much as I do enjoy heel-toeing, I am not at a pro level. I still like to row the gearbox so I'm hoping SRM will let me do that at the track a bit more efficiently.

^^ you will love SRM. I drive heel toe by instinct after all these years, so it actually takes a quick adjustment in the 370z to stop trying to do it yourself. But the SRM is obvously 100% accurate so its extremely smooth and nice... for example... say you are coasting in neutral.. if you push down the clutch pedal, SRM activates... put the car in a gear without letting off the clutch and keep coasting, you will find that SRM is just sitting there holding the RPM waiting for you. When you finally release the clutch, the RPM is so dead on that you literally do not even feel that you let the clutch up, you just feel the car start to engine brake. its great.
LOL you also have to get used to not wobbling the shifter back and forth when coasting up to a light... if you do that you look like an ******* (especially with a loud exhaust), because the SRM is trying to anticipate your gear selection and the RPMs are flying back and forth all over! |

BTW i just wanted to add that when i said 8000rpm would get us to 51mph, i meant if COMBINED with the 3.3 final drive from an automatic 350z. With stock final drive, 8000rpm would take us to just 45mph.
