Supercharger and intercoolers
 
There was a thread in the last week or so that had a couple clean supercharger and intercooler setups. I noticed that there was a setup that was supercharged but no intercooler. This got me wondering, can you run a Procharger/Vortech without an intercooler?

I can't find the thread to save my a$$...

My intake air temp gets up there WITH an intercooler..

Maybe with a big water/meth system or E85 you could get away without one...

Here's a datalog from a recent run.
I have the intercooler water coming off my crossover, so MAY be a bit cooler if I had a dedicated pickup.. ..
Lake was about 78 degrees IAT went from 118 to 151 in 55 seconds WOT 11 PSI.....

That's what I was thinking. I thought they created a lot of heat. Your running a decent amount of boost, I was wondering how hot the air gets in the in the 4-7psi range. Good looking setup you have their.

I ran 150* for years no issues.(without intercooler )
Intercooler dropped the temp 30*

I ran my boat for 5 years with non intercooled Vortech superchargers while I took care of my outdrive problems , Last year when I installed my intercoolers my boat gained 6mph , so I will say that you can run them without intercoolers but your performance will suffer .

How much boost was lost after intercooler was installed or did you pulley up?

Did you just add intercooler and gained 6mph or intercooler and pulley?

Did you run it on a dyno to see the HP gains?

ICDEDPPL 12-26-2018 11:58 AM

New pulleys. Same boost
If I recall, -3.17 underdriven before.
3.31 overdriven after


Did not run on dyno, saw no speed increase in boat .

I have zero experience with blowers, but I can tell you that given our nature to tinker, go for broke now and do all of your set up and rigging just once and live happily ever after. I’ve spent more weekends and money redoing what I thought was good enough for now.

From what ive read if you run a large blower with low boost the intercooler isn’t necessary, but soon enough you’ll want every mph available and rigging an intercooler later can be a pita.
