...someone please write something up on this, didn't find clear stuff on search.

I'm wondering myself about my spearco 27x6.5x3 ....is that kinda small to push over 400hp? Seems like it could be bigger even at 300whp.



ALSO im curious about people's thoughts on intake pipe size and length when it comes to turbo cars.

I've found no pipe at all to be best for sport bike turbo but they don't suffer from heat soak since everything is exposed to open air. 2.5" limiting under 400hp?
