sn-89 paxton intercooler?
Hi, I'm planning on making a few changes to my 383 while I have it apart. I found a complete paxton sn-89 unit, rebuilt, that I pciked up. According to the boost compression chart, I can run with either 6 psi or non-intercooled boost or 12-15 psi of intercooled boost at my target compression of 9.5:1. Compression was 10.75:1. Since I want to use my supercharger, and make it push some juice, the question is this...where should I go for an intercooler? I can fab things up...I just need to know if an intercooler is an option for me, and if so, where to look for more info. Thanks!
I also have to have some custom pistons made now, which is also why I need to know about the intercooler issue...I wouldn't trust HT383 PM rods and hyperutectic pistons to forgings under boost too much...also need to get some 30# injectors and upgrade to an MSD6 BTM

I would recommend buying a complete ATI procharger intercooler setup.
anyone have one of these for sale BTW? Im interested too.

dont bother. to get that much boost out of an sn89 is asking for trouble. Run it non-intercooled @6psi. By the way, you may or may not see 6 psi. On a built 383 I would imagine the blower would boost at 4#s

SN 89
I'm running a SN 89 on my 383 with great results. Max PSI with intercooler is 8. What's nice about this SC is you can buy a heat exchanger kit to keep the SC run cool. The SC can take a little more if the oil stays cool. Paradise Wheels will sale you an upgraded fan for $150.00 so it can handle more CFM for the 383. Don't forget to open up the intake, install bigger runners, good Hyd Lift SC Cam and a pair of good flowing heads with headers.
