Maximum horsepower for TPI
What is the maximum horsepower that can be supported by the stock TPI system? I have read several threads concerning changes to minirams & big mouth manifolds. I want to keep my stock appearance, but add a little more power. Thank you for your input.

About 400 is the limit, a link to Joe90's page is on my website.
Thats about as far as you can go with the original-looking intake system.

I might get easily another 3-50 Hp if i switched from Tpi to SR or Miniram with that cam and Head package i have.

My guess is 50hp with either intake. With your cam and heads that intake is KILLING you. I switched from a bigmouth, Lg tubes to a Mini and that is about what I picked up with a 219 and TFS heads.

That along with Accel not having SRs for sale this summer is what led me to a Mini. I am very happy with it so far. Next year with a new gear I will be even more happy with it.
It's a great intake to work with and 350 rwtq isn't exactly like it lost much tq compared to my 354tq with my bigmouth setup. Thing pulls great to 6200.
