did some serious porting to a stock TPI base?? I saw mention of him and it on this board a while back, so i need response from here too.
Where the runners attach to the manifold, he took that area and opened it up (kinda siamesed it) for a larger plenum area for the runners to feed from. Anyone knwo who or what im talkin about? i was wondering what the results were and such.

 

Transferring to TPI forum.

I believe your looking for Madmax.
I don't remember the exact results but there was probobly a loss in low end replaced by extended high end. He had some dyno numbers also, from a 305 I think.
