Is it worth porting a HDI head
#8
I found when playing around with Meth before (not the crystal kind) that even when I had really low intake temps of 20C (without an intercooler) and lots of boost, it still wasn't as good as an inter cooler. We came to the conclusion that the water must just evaporate and take up space that could otherwise be air.

Have you put a probe in to your intake to see what kind of inlet temperatures you're getting? Meths could be good but not too much in my opinion. I had them with an intercooler too, and on a dyno it added about 3 BHP across the whole range. Not really worth the money to me, depends what setup you have though.
