[Full-Race Geoff]

here are some dynoplots showing our expected spool and peak power for our most popular 30R and 35R turbokits.

Please keep in mind these dynos used smaller cams, smaller intake manifold and *slightly* more restrictive turbokits than our new 06 Si setup, indicating our 06 Si kits will make even more power.

30R kit @ 20psi, small cams (you guys will be +20whp here)

35R kit @ 14psi and small type s cam + intake manifold (i expect your motors will make ~25whp more)


35R kit @ 24-25psi and small cams, small intake manifold, restrictive exhaust setup (i expect your motors + thermal will make ~40 more whp)

As promised, here are 2 cfd images i promised showing what causes boost creep:





here is a picture of why full-race manifolds dont creep (hint look at the top of the WG tube)




DISCUSS! have a wonderful and SAFE 4th gentlemen, ill be back for class next week!!



edit i didnt see this post until now and did not want to leave you hanging

sorry its hidden with cardboard it will be worth the wait, i promise. to drop a big hint, our exh manifold *might* be similar to this s2000 unit...
