how good are these intakes under boost?? have seen alot of ported tbss intakes open under boost

 

We haven't tested boost applications on the radical ported truck manifolds, yet. Until it's tested, we don't recommend using it in a boosted application. Our radical ported car manifolds stand up just fine, but they're a much different manifold.

 

Yes, same here.

 

Good suggestion. We will keep that in mind as we persue getting flow numbers.

 

interested in seeing how it would hold up on a boosted application. around 14-15psi. any idea on hp increase for boost?

 

We'll let you know once it has been tested on a boosted application.

Thought I'd pass this note along that came from a recent customer that had us Radical Port his L92 truck manifold:

“It’s installed and truck runs really well, much better on the top end than before and hasn’t been tuned yet. I can only relate to you by seat of the pants feeling. The truck now breaks the tires loose shifting from 3rd to 4th. Damp pavement, I Know, but never did this before; (we are talking 90 mph). As soon as I send Justin the log and we retune I will let you know. I am really impressed by what you have accomplished for me.”
