Air charge temp after the outlet?

**Sponge** · 11-13-2009, 02:14 PM

Hello,

For those who have a air temp sensor after the supercharger, what the average temp you got? I presume it's not as hot as a turbo but I'm curious.

Thanks

Dylan

I am interested in that aswell.
It all depents on the amound of boost that is used.
Belgium, you live close by

Since your unit uses hot engine oil in it and no coolant or a intercooler you increase the air temperature a lot and would say that most turbo kits run much cooler inlet air then you will ever see. A VR4 usually with a good power pipe will read about 50 degrees over the ambient temperature. Since your engine oil is over 150 degrees and you pushing low CFM your heat soaking your air I would say 185 degrees average. This is the other reason you must set your timing back so much. Run a Water/Meth unit and combat the heat.

Thanks for the comment, my plan is to use first an intercooler and we shall see how cool is the air charge.

By the way, on turbo forum, a guy is running a Paxton 15psi on a Ford F150 and on the dyno the air charge never went over 128F without an intercooler...

For me, it's better to be safe than sorry especially when the intercooler costs less than $200...
