Hi all,

Although I have a Rover, and not a Ford, I was wondering if anyone could please help me with this query.

I am wondering if I would be creating any problems, flow wise, by using 2" ID pipework instead of 2.5" for the pipework run between turbo and throttle body. The car will be making circa 220bhp with a T28 (200SX) turbo, with 2x 2WD Cosworth intercoolers welded together to give a dual pass front mount.

Will 2" pipework flow enough for my requirements, or is it definitely necessary to use 2.5"? I'm not convinced the 'bigger is always better' argument applies here, if 2" is good enough. I already have the whole run in 2" ready to go on the car but need to know if I need to go to the expense of upgrading the whole lot to 2.5".

Thanks for the help.

Jim
