I agree, I am incredibly interested in the kraftwerksusa JRSC setup.... the numbers on the s2k are really nice, and the numbers for the fit are o.k. With the flash pro possibly working for the 09 and up, the rotrex units seems very doable.
i would buy it but im Building this Engine i got out of a car at work its a k24a4 im going to do it all piston rods, and valve springs and cams, kpro and after i will put the supercharger on i just want 340-350whp and drive it to work
Why a K24a4?

Do you have other supercharging experience in whence to compare this to?
What is response like?
How high can the boost be set to?
BOV needed?
I need to know!!
I have the Rotrex in the EP. Boost can't really be set. It is determined by flow and the impeller speed. Right now I see the max boost of 15 psi at about 7000 rpm. There is no whine like the roots blower. Nor does it have that instant kick. Its also different from a turbo. There is no lag and that sudden boost of power. The rotrex just pulls as you go higher in the rev range. If it wasn't for the max impeller speed. It would go higher. But with the advent of a two speed system. Its unlike any other. Basically. You step on a gas and the power increases from low to high rpm. No traction problems. And no boost creep to deal with. Also no tapping into the oil pan.
got it out of a car at work but the block is no good so yea just going to keep the head and some more part off it and call it a day so am just going to buy a k24a2 and build it
