let me just clarify so we are all on the same page here a good number is 400, a great number is 450, a "magical" number is anything over 500. That said can we hold you to great and magical right now?

Edit: actually if i buy this thing in the inter cooled race trim i expect magical to godly out of the box

400whp is a good DD number, but i'd hope the TQ numbers are almost even, if the power was around 450, i'd be ok with seeing TQ around 350-375

Kyle,

You mention that 2 things worth doing to the car that will prep it for a supercharger are the clutch/flywheel replacement and a cat-back exhaust upgrade to a 2.5". I was wondering about the cats themselves - worth replacing? You also mention not to do exhaust headers - which I understand means that a full exhaust is not necessary (as of right now). Are high flow cats unnecessary? Thanks for your advice.

Kevin

The Tq numbers will prob be about 350, I can't see this thing making 375tq, that's almost 100 more then a car with full bolt-ons. It would def be nice tho...

When we do our testing it will be with the standard cats and exhaust manifolds. I'm sure we will develop the tune further with the headers and high flows but to start with we won't have that informaiton immediately available which is why we are recommending that no one modify those parts just yet.

Keep in mind if you plan on purchasing the CARB legal supercharger then replacing the cats could and most likely will cause the car to fail inspection.

Kyle, any new info on the kit? Are there any pics of it installed in a 370Z, or not yet? I know Stillen is going to release info in march, but the S/C threads have been quiet lately & it'd be nice to get some new info. Thanks

All of our development is being done on the automatic G coupe that we have. We will be switching the kit over to the manual gearbox Z in a few weeks or so. The only differences between the two kits will be slightly better power out of the Z due to the manual gearbox and lighter wheels and a few mounting brackets. Everything else will be the same so pricing will be equal.

I dont know if this was covered yet, are you doing the testing with the Stillen exhaust or stock?

Kyle,

Thanks for your response. I plan on keeping the car CARB legal - good for the future of everyone so I'll just evaluate cat-back exhausts.

Cheers,
Kevin

Why not get a HFC or test pipe and do the swap come emissions time?

Kyle: don't know when you said you were leaving town but can you tell us what different set-up's you plan on trying when doing all of this testing... I am just wondering if you are going to be using any stillen parts? I guess the big thing for me is if I am going to be able to use any of the crap that I have bought and installed on my car or if I am going to have to sell it all when/if I get the S/C....
