Stock k20a3 w/ RBC mani + 65 or 70mm throttle body

[Andrew]

Has anyone here on ephatch tried the RBC mani + 65 or 70mm throttle body on a stock k20a3? I've been reading it up over on CRSX and it looks like some members were gaining 15-20 hp with these two mods. Just wondering if anyone knows more about it? Any input is greatly appreciated.

Cliffs:
1) k20a3 w/ RBC + 65 or 70mm throttle body
2) gains of 15-20hp?

you will lose power with an RBC

You will see a few minor gains up top but some drivibility issues. The RBC alone will account for a small amount of the low end loss but the oversized TB accounts for the majority. Now add in a stage 3 camshaft, Kpro, with just a maxbored TB and you will have a decent runner.

15-20whp gain???? a great work of fiction
