Anytime you force air into an engine, it sure will, should sound awesome

Sam,

couple of questions,

1. Will you be going for CARB approval on the stage 1 or any of the kits?
2. Will you be including an oil cooler with any of the kits? I"m assuming that this will be a must have.
3. Any thought on how the intercooler will block air flow to the radiator effecting engine temps, especially in stop and go traffic?

Thanks for all the updates, great work!!

A S/C shouldn't heat the air as much as a TT setup would, so an intercooler shouldn't have to work "that" hard in stop/go. At least, that's my thought.

G37Sam

However, not in a TT's case, the energy in the exhaust gasses is used to push a turbine which leaves little to be dissipated as sound. So the exhaust tone will be quieter than even an NA setup with that same exhaust. The engine itself though will definitely become louder as it is combusting more air & fuel

Boost is boost, the rotrex charger is nothing but a compressor like that on a turbo powered by the engine's crank shaft rather than a turbine. The same heat will be generated in either cases at the same boost pressure to an extent. That's why an intercooler was utilized.

Nice work Sam. Now all we have to do is mount the tranny , and oil cooler, for the 370.
Plus where did you mount the SC oil cooler? i see now why this profect takes a long time to complete.

Your best customer in Canada

Nice work Sam. Its going to be a tough decission between this kit and th Stillen. I really like the compressor GTM is using over the Vortec unit that Stillen is going to use.

My question is this? (forgive me if this has already been asked, this thread is huge) What are you going to use for engine Management? A computer flash or an actual engine management module? Next question is, will an engine oil cooler be part of the kit? (I really think this important)

BTW: the piping you have done is really clean! Under the hood my car will look the same as it does now with the G3 intake.

These are exciting times arent they??

I wasn't aware Stillen had announced they are now using a Vortec unit?

2fast4thelaw

Yep. Thier twin screw unit just wont work with the DTBs and they wanted a solution that didnt require an aftermarket hood. Thier unit will base around a Vortech unit that they modify and a water to air intercooler and hand held engine management system. They are definitly taking supercharging a whole new direction for them with the 370Z. All this is in the "Stillen Estimates" thread.

So far I am sold on the Rotrex compressor unit and I am excited to see the results of this GTM supercharger kit.

best bang for your buck is a terribly bold statement considering i can pick up 100hp for 800 dolars so fi this kit gets me 200 hp i will pay no more than 1500 lol

JB-370z

cant wait to see some numbers maybe next week

So will there be stage upgrade kits to get even more power if we feel we need more power down the road with the sc setup? I really want 500hp, and in order for me to buy this kit I need to know if it will be possible. I know we wont know any numbers untill its tuned but what do the sc guys usally do when 390-450 hp is not enough??? And nitrous is out of the question! Pulley upgrades and more fuel?? Also would lower compression pistons and new cam camshafts help or is this only with turbo??

So what are the pros and cons between the Vortex and Rotrex?

I dont think Forced Induction is for this guy! 800 bucks wont even pay for just the install. Hes not going to pay more than 1500 for 200hp.....wow, if you said 15,000 I could understand that but, jeez. Spraying is not a very smart way to gain hp. Your car would fit in perfect on one of the sets of the fast and furious, press the little red button at just the right moment to win an illegal street race But what ever floats your boat but wrong thread to be in for now! Untill sc systems make it to $800 a pop no luck here.
