Hi I'm just wanting a second opinion on the sizing of my intercooler piping.
Basically from the turbo it is ~43mm internal to ~53mm external, then the intercooler is 68mm external, then the throttle body inlet is ~72mm internal - its a rubber flange type thing so a metal pipe will have to go inside it, its the wrong shape to have anything on the outside.
So out of the turbo it is into a 45 bend then down to two 90 bends, both of these are step ups, 51mm to 63mm and then 63mm to 70mm, then another 45 bend to bring it inline with the intercooler.
After the intercooler theres a 90 bend that goes from 70mm to 76mm and then two 45 bends to bring it inline with the throttle body, then there is a step down to 70mm for the throttle body.
I'm just wondering if I've gone down the right route having the step ups on each 90 bend? I was just thinking it would be a little less restrictive than a normal bend due to a slightly larger diameter.
Also the section after the intercooler where it goes up to 76mm then back down, is that a waste of time or not? I was just thinking again with a bigger diameter hose it would be slightly less restrictive for the bends but I'm thinking 76mm is too big.
I will be running 15-16 PSI in a 2L to give you an idea of flow, any help would be appreciated, cheers.
