How much hp can i be lookin at doin this cause a full bridgeport on the 6 port engine is kinda pushing it cause of the closeness to the waterjacket. Just didn't know cause i have seen na street ports on some forums pullin 13's in the 1/4 mile with lots of mods, and i know people in puerto rico pull some crazy times with na's.

 

Very few people have done this, so I don't know if anyone can give any exact numbers. I would expect that combined with a standard streetport it should give a 30% power increase, but this is just an educated guess. I am doing this with my turbo-NA car, but that's a different story...
