Default How much power can...?

How much power can a basically stock tpi intake support with a good bottom end, cam and heads? I know that this really chokes off the power. I am just wondering even if you get the bigger base and larger runners and maybe even port and match up the openings what kind of power one can expect the tpi to cut off at. Thanks

Under what caveats? NA? 350? stock heads? stock cam?

300 seems to be the cap.

You could conceivably pull out 400+ with the right cam choice

If you want to add a little top end breathing with stock base & runners consider the siamese base mod.

Here's an example of what was obtained from a modded L98
