HKS GT Charger and TT planned by HKS

CCCLXXZ

Great question,

I didn't intend to make it seem as though power gains were not the goal, but wanted to reference that historically on the 350z the HKS system provided gains of 70-100 whp if my memory serves me correct. Compared to other FI options that were offered for the VQ, this fell into the average spectrum.

While some members on the board may be looking for the biggest and best bang for the buck regarding modifications and power, my goal is to incorporate unique and well engineered products to create a balanced and well appointed 370z. A calculated combination that I look forward to execute and more importantly enjoy.

The HKS GT system fits the bill, and I am eager to see how the more recently design HKS charger compares to the outsourced rotrex unit used in the past.

What else is important? How about reliability.

What else matters? it says HKS which is almost as baller as the word Porsche hell I'd pay 4 times as much for it(sarcasm).

Reliability, power delivery, drivabilty. It's probably going to be another High RPM, boost building, centrifugal Heat pump like always. I'd go twin screw(not roots) because I need torque and low-end to pull out of a corner instead of balls out top end power that isn't as usable unless you're a dyno queen.

I'm gunna have to agree with you. I'm going to go with the Twins as well.
Low-mid End power seems more useful on the track as well.

Twin Turbo is nice but I'm not really a turbo guy. They make great power and it feels like the car is gonna take off, but I hate "hitting Boost." I'm talking A Lysholm style twin screw supercharger that looks like a roots blower but the rotors are conical and in a male female relationship that positively compresses the air in side the case of the blower. You "hit Boost" as soon as you put the pedal to the floor and it's at peak right away, there is no boost curve. HUGE torque gains and effectively it's like putting a V12 in your car. It has advantages over a roots setup because the rotors are more efficient so the air charge is cooler and it take less power to drive the supercharger. It also doesn't taper off towards redline like a roots blower does and a whipple 140ax 2.3L blower is capable of pushing 600hp worth of air, with units up over 4Liters available. Of course no one makes a kit with one of these compressors currently so you would have to make it yourself, good thing I happen to be a machinist huh? oh and the whipple i mentioned costs about 2,400 for just the compressor.

That doesn't sound too good. Sounds like a spin-fest.
