Twin Turbo vs Supercharger
I have been looking at some after market stuff for the G35 coupe and was wondering if any one knows the difference in hp gained between the TT or supercharger??? Also what are the different pros and cons of each???
www.sgpracing.com
Greddy Turbo Kit: "Everyone this kit has already made 417 RWHP @ .75 bar of boost!!!"
Power Enterprises Turbo Kit: "420.6rwps @ 0.5kg/cm2"
www.procharger.com
ATI Procharger C2 Kit: "55-60% Increase in HP and Torque" ~370RWHP
www.stillen.com
Stillen Stage 3 S/C Kit: "In Stage 3 Trim, this Supercharger system will produce approximately 405 hp and 381 lb-ft of Torque."
Pros: They all give you more power.....
Cons: They all cost a boatload of money.....

It’s all in the way they make WHP.
I am biased for turbos for one reason. They, if every mod is equal and boost is equal, will ALWAYS make more WHP then a SC. WHY? For the simple fact that turbos use wasted energy to create WHP. So you really increase the efficiency of your motor.
A super charger takes 10-15% of the engines power to create boost.
And now there are two different Types of SC's
A roots type, which is a metal box with two screws that force air directly into the intake manifold, the Merc's and MANY Muscle cars run these.
Pros? They are INSTANT boost, so the torque is flatter then an 11-year-old girl.
Cons? They are not too well in high boost applications; they normally run 5-9PSI, which are MORE then enough for a Z. A lot of them are not intercooled and if they are they are air-water.
Then there is the Centrifugal Super charger. It is basically a turbo cut in half and turned by the crank again instead of exhaust gasses. They do not offer as much low end Torque as they build boost just like a turbo but do not give that turbo boost spike, they are limited to the crank speed, but have great top end abilities just like a turbo.
What I also do not like about SC's is the lack of wastegate, meaning that you have a pulley set to 9PSI, that’s it, 9PSI, and it gradually builds to that per RPM, while a turbo snaps up and gives you whatever boost it is set. Also, if you are in say Colorado, that 9PSI of boost is now 5PSI, while a Turbo will still hit 9PSI, because the wastegate (if set to 9PSI) will not open till 9 PSI.
The Supercharger kit for the Z is great, makes the engine like a Big V8, the turbos are obviously peakier and will have better top end for sure.
