Kraftwerks Supercharger Unit
 
Want to make 450hp on an K20a dc5 motor should I use a C30 or C38 blower. Running E85 gas.

C38.

C30 will max at about 435bhp

Thank you I guess C38 it is.

Going to be using a 100mm blower pulley. 8300 rpm redline. Does this seem ok.

Just be aware that the C38 series Rotrex units tend to shear off the turbine shaft if you hit the rev limiter too often. And you will :-) Honda engines were very susceptible to this due to their high reving nature and power delivery.
The C30-94 does not have this issue. And it will still spin FWD tyres.
Id consider the new C38R unit which is supposed to be a better design.

In either case, it will be a blast.

Thank you Lotus I am considering putting in a shift light so I shift before hitting the limiter.
