Just can't decide
 

I'm running E85 with a HKS L Spec exhaust, front pipe and EL headers, among other modifications but I just can't decide between a HKS v2 Supercharger or the Sprintex 210 Plus Supercharger (Intercooled).

I realise that the HKS will grant me more power, but the Sprintex comes with that oh so sweet whine.

What do you guys think? Sacrifice some power for the whine, or sacrifice the whine for the power.

The price difference ends up being about $100, so the money is not a concern.

Go with a Rotrex kit. No sense in wasting money on the HKS name.

Different animals altogether, the HKS (and the Rotrex) are centrifugal compressors. They make more peak power and might be better for a track car/race car, the innovate may be better for mostly street driven cars. The innovate has a broader torque curve and a bit less power (plus the cool whine). Street acceleration between a well tuned innovate kit and a well tuned centrifugal kit, probably not much difference overall (innovate pulls lower, centrifugal pulls up top). They're both lots of fun, just different characteristics.

When I was making my decision, the cooling properties of the Innovate kit are what made me go with Rotrex. Sure the whine is awesome and the low power band are real fun for street driving, but some of the temps were real high with the kit. I was real close to pulling the trigger on it though.

I would look that the Kraftworks and Jackson Racing kits which both utilize a rotrex blower. @Vex

I can't wait for some asshole to jump in here to tell you that you need to use google for your research

With a full exhaust you are not going to hear the whine too much when in the car.

You should use Australian Google for your research OP. I would go with the HKS Rotrex Supercharger.
