The large pressure drop offsets the better cooling with higher turbo drive pressure. Its a balancing act; high flow, high cooling or a little of both. A free flowing intercooler that doesn't cool very well is better choice than a very restrictive one that gets the temperature near ambient.
Quote:Any vehicle which could fit it could use the Isuzu NPR intercooler instead which is about the same size/shape as the Volvo with much less flow restriction.Or pretty much any core if such a large amount of space is available. The only marks in the Volvo favor are its cheapness and common availability.
Quote:Stock boost is set even lower than that (5-6 psi) but the stock intercooler still seems to work well with it raised to ~15psi.Yes, I understand there is even a factory "overboost kit" that allows 13psi for a limited time.
