Intercooler Piping 2.5" or 3"????
As I work best intercooler piping, 3 inches or 2.5 inches???? At this time the turbine to the intercooler in 2.5 inches and 3 inches intercooler to trottle. The nozzles of the intercooler are 2.5 inches and 62mm trottle. 31X12X3 intercooler, presicion turbo 6262sp

Re: Intercooler Piping 2.5" or 3"????
My software can do the math for this, but like they said depends on the power goal... but also depends on the boost level
http://www.superchargerperformance.c...alculator-v2-3
The higher the boost level, the more compressed the air, the less id piping you need... flowing 500hp @ 0psi will require a larger pipe vs flowing 500hp @ 25psi
So what boost level / power level are we talking here ?

Re: Intercooler Piping 2.5" or 3"????
2.5" becuase a smaller pipe will force the same volume of air than a larger pipe but faster. Since it is not exhuast piping no need to worry about backpressure. Although to small a pipe will bottleneck large cfm. If the kit was designed to go 2.5 to intercooler and 3.0 from intercooler to throttle there was probably a specific reason, but you should avoid reducing the pipe size to the throttle. If you run 25+ psi like you want to, it would be better to increase turbo out to intercooler in.

Re: Intercooler Piping 2.5" or 3"????
The trade-off here is that 2.5" piping will fill faster (build boost quicker) and force the air to move at a higher velocity into the engine; however, at a point, 2.5" piping will add a lot more resistance to the air charge which does lower the power per psi that the turbo produces. If you look in the Forced Induction FAQ, there is a thread which outlines where and when you'll see friction losses due to overly small piping.
