Im looking for 1 that will work well with a built motor and give me the most boost,,,, who makes those?
Well, there are lots of options: Roots, Lysholm TS, the centrifugals. "The most boost" is not always what you want. Can you explain your engine setup in more detail or is this still in the "fantasy build" stage?

I have the complete 08 civic si (z3) motor, trans, rbc, also have a 07 accord bottom end. Ordering some je 9.01 compression pistons and brian crower rods. now i have always wanted boost but a supercharger looks clean and im just torn in the middle of which way to go.:confused:


so way past the fantasy part, main goal is spirited daily driving thats reliable.

Well, since you are using low-compression pistons, a centrifugal blower would make the most of that. You can search here for the Kraftwerks kit thread. That is what I would do. Good luck.

9,0:1 is for turbos, I would recommend 10,2-10,5 :1 if your going for a Rotrex/Kraftwerks or a lysholm TS.

I agree with that. I guess my point was that if he chooses low-compression pistons, then the motor will want a lot of boost and a centrifugal will do that best. I run about 11.5:1 compression with the M62 and think that's where the Roots-based units want to be.

psi for psi... I got you all beat!!

I have a pre-production KraftWerks Super Charger Kit using the smaller of the two blowers and a 110mm pulley (7psi @ 8500 rpm) and the car makes 327hp and 210 lb. ft. Tq. The only part not stock on my K20A2 is the RBC intake manifold.

300WHP with CT-Eng is possible, I'm making 294 WHP with a 3" pulley with a very sh!t tune... properly tuned it should be around 310WHP, drop in some IPS cams and you'll be seeing 330~340 WHP with a full exhaust system.

I'd interested in seeing what the power delivery looks like.
