After dealing with so many other supercharger system over the years. belt issues was always a problem with a lot of them. So we went to extreme masseurs in our design strategy to make sure that belt slippage and brake wont happened. Our system have about 80 % belt rap around the pulley which is really unheard of. So to this day I"m happy to report there has been ZERO problems with our belt set up .

With right combination of SC housing and pulley I think it will

For street use (including spirited driving on country roads), Stage 1 would be plenty for me. I also like that the boost is only 8 psi. Does that boost level pretty much hold across the rev-range and power/torque bands?

All the way to red line rock solid.

Sam...what are your thoughts on this kind of tune holding up on the auto tranny? That would be amazing IMO if it could work out well....

I know that its the same 7AT that is also in the 390hp FX50...

shumby · 02-28-2010, 12:18 PM

and the 420- m56 so the tranny will hold

shumby · 02-28-2010, 12:22 PM

Now this is stuff I like to hear!

LiquidZ · 02-28-2010, 02:29 PM

Sam, sorry if this has already been covered, but why are your running with no air filters?

370z4Steve · 02-28-2010, 02:38 PM

if thats with full stock exhaust system its like close to 500 HP and400 FT/LB @the crank ...

going for that CARB Cert eh SAM ?

Now, with the older VQ's, 8 psi was just about right to keep a nice level of reliability on a daily driver with stock internals on pump gas. I wonder what's a good amount for our newer VQ37's?

Well the newer VQs have a stronger set of internals so at least we know we can run what the older VQs did safely and 8psi isn't too shabby.

We do run higher compression ratio than the VQ35, though.

Oh really, wasn't aware of that

Not to be desparaging against any one vendor, but barring any wires that will no longer be there, which engine bay would you rather have? Yes, this is a rhetorical question.
