TTE Intercooler Piping
TTE Intercooler Piping
Small pipes 2" are fine for low boost applications.
The intercooler kit I gave to Pat was on my old almera running 270bhp low boost 330bhp on high boost. Any more than that it was getting heat soak and became insufficient. Plus being smaller pipework it boosted quicker.
2.5" cooler piping just allows a larger amount of air to pass freely and quicker. I changed out to 2.5" towards the end... But I went to a twin pass intercooler so I could shorten the run to the cooler. This way I didn't get any lag after the change. Instant boost
I hope this helps
