Preparation for the STILLEN supercharger

1slow370 · 03-10-2010, 09:58 AM

honsetly the kit is going to be about damn near maxed when you buy it from either company. a general rule of thumb for car with a drivetrain as sturdy as ours is to limit it by the psi no the horsepower. an 8 psi turbo kit and an 8psi supercharger kit place equal strain on the block. superchargers make less power because it requires hp to turn the supercharger either way 8psi of air with the same ignition advance is going to generate the same cylinder pressures. right now the highest i would take the stock motor is in the 7-10 range depending on how ballsy you are.

I think we could get away with 10 psi on a good 93oct tune. As far as being maxed out, I don't think the Stillen kit is near maxed out. As I understand it, they have enough room on that compressor to go well beyond the limit of our internals.

Anyone know what the max psi is for that blower?

22 psi for Si trim.

Woof, 10 psi, I can only imagine the excitement inside the cabin at full throttle

Figuring out the proper efficiency "range" of a Vortech supercharger takes a few things:

1) Volume of air you're trying to move
2) RPM that you're spinning the supercharger
3) Size of the engine you're trying to feed.

Basically, there might be a "sweet spot" of efficiency on the compressor map for the 370Z but it's going to be very different for an engine like a Charger SRT-8 however you can still use the same blower for each application.

One of the great things about the Vortech V3 supercharger is that it is a very efficient blower at over 70% efficiency.

I mean that it is maxed out in the sense that after purchase of said kit it is going to cost you like another 6grand to safely up the power. hell if you don't change your clutchand flywheel just buying one of those kits is already over the max the car will take. I like to work in terms of the package as a whole. I think 10 psi would be doable as a race tune but i shure as hell would pulley down to no more than 6-8 for regular use. 10 psi is def. meth injection territory to me. hell i'd think of putting meth on an n/a car just so i could run a nitro booster in it. i'd try to find the most oxygenated shyt i could find.

So, i have some questions here for Kyle&Josh@Stillen, are you going to send out the S/C kits with uni-chip or control box just like you did the the old 350z S/C?
Or are you planning to use Osiris UpRev reflash and tune?
Do you thing the UpRev is better than uni-chip for tuning?
And what made you go with that route for the tuning? (uni-chip vs uprev tuning).
