I know the new one is better but my how much horsepowers?

I'm debating on spending the extra dollars to get the new one or just get the oldler one.

My mods r in sig.. What would I be looking at in power with new vs old.. I would get a cluch, injectors , n FMIC also

 

the new 80mm housing minimizes surging but i dont be leave that it makes much more power?!

 

There is a thread on here comparing the 2, the 80mm housing does not make any more power over the 64mm housing. It just helps with efficiency at low boost.

Found the thread.

I am not aware of any back to back testing on cover swaps only.

 

does not make any more power why do people think that

 

maybe the only improvement would be if you went from a 2.5" intake to a 3" intake in the process?

 

i dont know you tell me you have the 80mm lol i have the 64mm and mine is not in use yours is . why not try it doubt it seriously if that was the case fp would have discontinued the 64mm

 

I swaped out covers from the 64mm to the 80mm. I did not feel any power gains. It made the car feel smoother and more reponsive. When I boost to 30psi it does not surge anymore. It simply hits and holds. I love the sound as well. The cover is only about 200 dollars and as long as the turbo is out it is not hard to swap covers.

 

great stuff everyone! thanks for the help!

 

Did you do the swap at home?

 

yea curious about cost of swap and install? I would assume you could get a 80mm housing from fp to put onto your existing turbo?
