Hi all,
I'm starting a build for limited class racing (boat). Basically stock rules.
Cant find any more pre pollution heads that haven't been run through the system so many times that we can make a decent head out of AND stay within the rules (no chamber mods etc)
Are pollution heads with the EGR passage in the center two exhaust port any good?
The EGR passage is opposite the short turn in the ex port. Will this hinder flow if the passage is blocked at the other end by the inlet manifold.( will it create enough of a stagnant effect to be negligible)?
I can flow test but only have a 110, will 10" be enough to get a worthy indication?
Cheers
Nick
