I believe the issue with the STG 1 blower was that it couldn't get up that high reliably because it flows less and because of the VVEL overlap issue. That's why, as Sam has pointed out, the STG 1 blower on a 350Z made more HP.

So much awesome, great work on getting the kit done as this is the best news I have seen yet! Time to get serious about building up the car mod piggy bank. :tiphat:


How much work is it to install the new poly engine mounts?
Not bad at all, Couple hours worth of work .

Looking forward to see how this kit performs with GT-R manifold and VVEL tuning. Not to mention an exhaust and HFC's, test pipes, or headers.

That is what I am saying, the efficiency range of the stage 1 is at its max. So trying to run a higher PSI or a lower PSI, on stage 2, is not a worthwhile test.

It can be done with the Stage 2 unit it would just need to have a bigger pulley to slow the unit down.

I do see you point now however, with both units using the same pulley now it doesnt make sense.

Which is also why Sam said the stage 2 does not need a smaller pulley as it did not show any increase in power, similar with the stage 1.
What part of "if possible" from my post above did you not understand?

I am looking into learning the 3.7's "potential" more and figured what you had posted above. But again a stage 2 @ 8psi would be a nice comparison.

Again, read the thread.
Not going to muddy up this thread.

I understand what your talking about Alberto Sam is the only one that can do that though.

Ugh! I stay off of the forums for 24 hours and I miss this thread. Andrew had to tell me about it. The "lower" power car Sam has is a G not a Z. He using a couple of cars for testing the Stage 2, mine being one of them. Went to GTM today. It's the home stretch for the S2!!!! Whew!! My patience was wearing thin (shut up Andrew!!), poor Sam for having to deal with me too. Sam thinks my car should be done within 2 weeks (again SHUT UP ANDREW!!!! :p). I'm using my ipad, so I'm not sure I can post pics from here. Any ideas, anyone?

Put the pics on a hosted site or up load them on your forum account. Then paste the code. Boom, Done.

Well you guys leave Sam alone so that he can finnish the SC for the 370z.
He needs to be left a lone so that he can finnish the kit.
That way I will get my SC and kick a GTR at the drag strip.
thanks

lol

if you beat a GTR it will be shock to us all. That would something worth seeing.

Right now a stock 2010 gtr runs the 1/4 in 11.75. My N/A 7 AT goes 12.42 with 309 rwhp. bump it to 470 rwhp and my car is light 3372 lb with me in it.
I can not wait till I race one.
" soon to be a GTR's worst night mare in the 1.4 mile."
Ask Sam about my car .
