Re: [DML] Intercooler



Don't have an intercooler on mine and don't want one. Water injection instead. How the hell often are your turbos in use? Mine come on when I'm passing or climbing a steep grade at elevation. 99% of the time it's a normally aspirated PRV.

Yes, I do (and did) see your point but even just by making sure the 
x-sec area of the turbo outlet is kept constant or put through a venturi 
if the throttle is larger, and keeping those sizes in the intercooler 
with a decent density of channels, you'll be hard pushed to make things 
worse. In other words, apply a bit of common sense (something which Nick 
clearly has) and you should be okay. If using a donor intercooler from a 
productio engine - how big is that engine, how high is the boost and 
what does it rev to - that'll put you in the right ballpark.

I was intersted to see your suggested reading matter trashed by several 
of the reviewers on Amazon. Put me off buying it :-)

Best Wishes
