This is a stage 1 kit.

I guess when you put "up to" before it, you can write whatever you want. Shouldve just said "Up to 600" with supporting nitrous.

Anyway, what PSI were you hitting on these runs?

I'm not too surprised, I thought it would be close with both units at 8psi. Looks pretty good for having no exhaust. I'd expect that with exhaust you'd be around where I am.

Nice numbers though. Congrats on getting rid of the flutter too. Enjoy the car.

Oh and HALLELUJAH!!!!!!!!!!!!!

You know what man for real, Go some where else. Why must you bash everything that comes out except something you own or unless it comes from stillen. It is getting old, why don't you go make a bashing thread. There is no reason to turn every GTM thread and stillen SC thread into a bash.

ohhh frank.... lol

Since that was stage 1, wonder what stage 2 will handle with minor upgrades

Maintaing boost press has nothing to do with head unit (the supercharger) this is a 100% accurate information and here is why..

With the same Supercharger same pulley size that we are making 8 psi with on a VQ37VHR and making roughly 410-420 rwhp, take same setup configuration and install it on a VQ35HR engine and you will make 14 psi and roughly 475 to 487 RWHP ( we have done it ). Why ?

One engine has VVEL and the other does not.

Our stage 1 supercharger kit is sized perfectly to this engine and that is why we are getting the great torque curve and power that we are getting, Now if you ask me how can we increase the boost pressure on a stage 1 ...simple answer control The VVEL witch we are about to do that here shortly.

We just started the testing phase.

So Sam let me understand this, you are saying you have control of the VVEL

Not trying to de-rail but this is huge news

We have the tools in place and we just begun the testing phase .

I'm not sure if you're familiar with mathematics or not, but he is very clearly making 500hp. We advertise our supercharger as brake horsepower (aka at the flywheel) due to the wide variation in chassis dynos. You see, the OP posted some very useful information that you chose to ignore...namely, his stock dyno graphs on the same dyno.

So, this is where 5th grade level math comes into play...ready?

The OP made 278 whp (that's the average of the four runs posted) with his stock car. Assuming that his car was making the Nissan advertised 332bhp we can divide 278 by 332 to find out that 84% of the power is making its way to the wheels (according to the dynojet).

Now, let's take the average of the four supercharged runs which is 417whp. Now we can divide that number by 84% and guess what we get?

An average of 498 crank horsepower. Sure, 2hp less than our advertised 500bhp, but as you can see from the four runs, it is well with the standard deviation from pull to pull.

No nitrous required for our supercharger kit to make the advertised horsepower...also, no cats were harmed during testing.

Thanks for the clarification GTM!

Finally someone to work on teh VVEL. Cant wait.

Q8y_drifter · 12-13-2010, 09:32 PM

This is awesome!

Thanks Fezzik for posting up the dyno graphs.

Bro, you know very well those numbers are flywheel hp, not wheel hp. Why you trying to spread lies/talk sh*t?

Nixlimited · 12-13-2010, 09:44 PM

Great numbers guys! Is this on a CARB legal kit?

Also, why is there less torque with the s/c below 2750 rpms? Is there that much parasitic loss?

Lower than what? Stock, because is has more than stock from those dyno graphs the whole time.

I'm talking about Torque. It's very clearly lower initially, particularly below 2500 rpms.
