That makes sense. It's just opposite of what I was thinking.
The fact that more air in with the bigger tb resulting in more rpm wasn't clear in my head.
But with a bigger tb=more rpm at the same tps then you would have lower line pressure at a higher rpm than you did before the tb swap.
Thanks!

 

This may not be the place but, Ion & Dan with all the tuning that you have done can you put on a TB to big and hurt performance or is like i posted above as long as the car is tuned youre fine

thx this is great info it was not out there before nor i could not find it

 

Yes, you can hurt performance if you put a (significantly) bigger TB than needed. The car will tend to bog down whenever you try to go WOT.

There's a formula here somewhere for figuring out how much air your engine needs and how much various TBs will flow.

 

Schurters LT1, you should check out www.kwfbody.com if you haven't already since your from KW.
