Performer RPM intake?

[ssba]

ok, but will the CH4B (RB Block ) be every bit as good as the DP4B (B block) that was tested in the article above? The runner length and other things will be a little different..? I got to make a decision..I guess i should have asked whats the best performing RB intake out there minus the performer RPM or anything else that tall..

You will like the ch4b. It is my favorite dual plane. I went to the rpm when they first came out reading all the magazine Hipe. Waste of money.
The best bang for the buck is the ch4b, tm7 and Weiand tunnel ram depending on your design needs. I have tried nearly all of the manifolds made and those three I won't let go of. They have you covered for most any sensibly priced engine build
All of these manifolds perform great and can be bought right.
I had the rpm on my car for less than a week and got rid of it due to being disappointed with no improvement over the older designs I already had.
If you don't have a manifold now and you want the newer
design its not that its bad but to take off a older manifold
expecting gains is a real let down. And to add to the insult
you just paid triple for no noticable extra power. That was my experience.

will the CH4B take a thermoquad without any adaptors?

I haven't tryed a TQ on the ch4b myself but it looks like
It could be opened up on the secondary side some if needed.
