I have been looking at buying Pineapple Racing's 6 port sleeves. Do these yield much of a horsepower gain? Are they worth it?

Thanks

 

I actually just asked Pineapple Racing that on the phone yesterday. Now I know they are trying to sell their stuff, but he claims 5-8 hp increase. I think that is reasonable to assume and I beleive him. I'm going to reserve mine now. His stock got sold quick last time.

Q: So are they worth it for $49? Can fish swim?

A: Yes!!

 

Made a such a big difference, it was NOTICABLE
