I am installing a megan racing intercooler 12x24x3 for the core. now its a 3 inch outlet on both sides. does anyone see a problem running 2.5 inch intercooler piping for this at all? how much would this affect the flow or possible pressure drop? If anyone could help me out i would really appreciate it. thanks

2.5 is too small....2.75 is OEM

 

2.75 is really the smallest you would want to use. I noticed a big difference between 2.5 and 2.75 inch end tank piping. At my high boost settings, my air fuel ratios changed from 10.9 to around 12.1. Of course this is at 25 pounds of boost. Thank god i had my water/meth injection on and race gas.

 

yeah i know 2.75 is OEM, it just seems that no one seems to carry 2.75 in around here? anyone have any ideas?
