intercooler pipe to inlet/outlet, How does it effect? Options

[urbandork]

On my turbo set up im running 2" pipe.

The intercooler im looking at has a 2.5 inlet/outlet.

My question is what effects will i see by running an intercooler with larger inlet/outlets then the pipe that im running.

Should i see a big diffrence and if so in what presure drops, lag, ect, or will it not really matter.

why not just change out ur piping so its correct. unless you already bought it.

only thing i could see happening is less air flow but not by much. i really dont see it causing any problems.

Yup already started to buy 2 inch pipe.

But if i shouldnt run into n e pressure loss or super lots of lag then ill just hook the 2 inch pipe up to the 2.5 inch intercooler inlet/outlets.

In my intro to aerospace class we studied airflow and stuff. And the way i see it as long as the inlet and outlet are the same size then the airflow rate should remain the same.

This is the idea behind intercoolers with different size inlets and outlets.

the only thing i could see happening is the outlet side when the air comes form 2.25 to 2. but its such a small amount i dont see it effecting/affecting much.

coolios.

yea that wont hurt ya...and DONT go to the bigger piping, that will only increse lag.

I'm running 2.5 piping with 3" inlet outlet on my IC.

Its medium size, but its also for a 3sgte too, not a 5sfe.

just get the correct size reducers to got from 2.5-2in and youll be fine.
