I wasn't sure what to call this thread to get attention. It may not anyway. I seem to be on the road less traveled.

My recent mounting of an H T/B to a ported A1 manifold, poses some interesting questions. All ports have been epoxied and smoothed, including the IACV. I no longer have an external MAP sensor either (not that it allows air in but I have zero vacuum hoses). The current set up required opening the butterfly and re-adjusting the TPS to match, in order to get enough air to idle.

I'm curious if anyone would have a suggestion on how big af a hole or holes to drill into the butterfly so I can leave it shut, or close to it, and not have to adjust the TPS as much. I'm thinking a pair of 1/8" holes to start with. I don't think that will be enough but obviously don't want to go too big.

I'm hoping the added air will show on the wideband and require more fuel pressure to be in the same zone. If it does, I know I'm making more power. Right?

How do you plan to run the car with no map sensor?

No more "external" MAP.  It's attached to the H T/B.

Ah!
