Intercooler piping size?

510 Views 5 Replies 3 Participants Last post by  Steve Wood
The big Ford IC is coming along nicely.
I was planning to use 3" piping from the turbo to IC and the IC to the stock up pipe.
Will I have lag with this setup?
I am using the stock tyurbo at the moment, but plan on upgrading to a PT54 or equivalent.
Would I be better off using 2.5" pipe instead?
I am upgrading from the stock intercooler to a ported Ford IC......
Expertt advice needed before I finish the project!!!!

Tony Dequick says there is little to no loss with his larger pipes on the front mount IC's that he sells so I would have to think that yours are no different. Unless there are leaks in the hoses that connect the pipes.

At least that's the way I look at it.
Thanks for the reply......
I was hoping for that type of answer!
I guess I will try the 3" pipe, easy enough to change later if it doesn't work out.
I will post some pics hopefully once the Ford project is done.

Best I can tell from Tony's comments...either one works about the same...I would use the one that fits the best, I think...

Come on!
3" pipes would look way cooler! That's worth at least .5sec in the quater right?!

well, they look cooler...but I don't think anyone has shown any improvements...at least down to 10.0

and they get in the way of stuff sometimes...

but, I agree, they look cool!
