hi id appreciate any info on which intercooler is most efficent for a s1 currently mine has a radtec item fitted which peaks at 17psi and holds 14, but i was thinking a grs large intercooler may work better and allow me to run a bit more boost id appreciate all the info or experiences people have had with these items before i go and spend a wedge on a new one thanks in advance

 

nothing wrong with the radtech cooler (if that's the front mount you mean?) even if you want the boost increased!

don't waste your money and spend it on the engine!

 

GRS make a very niceeeeeeee front mount for the S1.
