Stillen Supercharger estimates???

john370z

Vortech or Rotex???? Please tell me if I am right? Both offer little low end torque/hp. (which the 370z could use as much as it can get) Both kits for other cars like the Mustang cost around $5K? Both are good for long periods of use and will last many, many miles? Which is better?


So GTM is using the Rotex and Stillen using the Vortech.....Who do you go with??

First off, I completely see what you are referencing when you mention the Vortech units on Mustangs and Camaro's and Challenger's...However, the 370Z and G37 is VERY different than those cars.

For starters, the dual throttle body design has caused us to make some pretty drastic changes and that in itself has required a lot of creative engineering. One major difference between our supercharger system for the Z's and G's when compared to Vortech's supercharger system for the Mustang's and Camaro's is that we have had to design a new intake manifold. On most of the Vortech kits they are able to re-use the factory intake manifold which greatly reduces cost. Unfortunately on the Z and G, that was not a possibility.

I have 2 more questions for Kyle:

Will the newly designed intake still have the dual throttle bodies or are you modifiying to have just one?

Also will the air to water intercooler use its own water resovior or share it with the engine coolant?

Yea, to keep costs down and to simplify the process we have maintained the factory throttle bodies.

Yes, the coolant for the engine will seperate than the coolant for the supercharger.

I think the Z has good low end TQ in the first 3 gears and it climbs the rpm range quickly so the TQ should come in quickly. Where I find the Z lacking a bit is in the crusing range and then jumping on it. It doesnt pick up as good cuz your in a fairly low rpm (7AT anyways). So of course you have to jump down a gear or two to get it TQing good. So which type of SC would be best for this?
