Re: I need a Project
The Berts product is well-made and well-machined. It will have to be matched to the user's exhaust manifold and flattened/decked (machined).
Enlarging one's own intake that is already mated to an exhaust should not be too big a task for a machinist with a boring bar and mill.
The bored enlargement needs to be carried up to the division point from updraft to sideways and the increased in area exists. As thin as the wall is, as deep as the transition is, a cutter on cast iron loses too much rigidity and a radius is unnecessary. Just boring the updraft tube to the transition is all that is required; at the top of the updaft portion, the volume increases 224%.
Send me your intake manifold and I will bore it out for you, if Berts can't.
D-n-t-S
