Well, first thing I did today when i got home from work was a test drive. Bypassing the intercooler allowed the setup to hit about7-8lbs, i was easy on it...
So now the next question is; what is wrong with my intercooler setup? The IC is a 24"x3" core with 3" outlets.
What do you guys suggest I run or do with this ic?
Thanks again,
Z

Ill recheck the IC for leaks as well as the whole system this weekend. I have done it once before and didnt have a leak until about 1 bar, coupler popped off.
Could I put a smaller pulley on to compensate for the 5 lbs i lose?

You have to have a problem for it to be losing that much boost through the intercooler. I would find the problem and not try to spin the blower harder to make up for it. I doubt you could anyway, as the leak or restriction (could be a rag in there) would most likely become worse. Bob

Ya, the benefit is that I know this cam is correct for boost.
I didnt have any luck with the intercooler today. I pressurized the system today to 20 lbs and didnt have any leaks. I test drove the car again and was hitting 3-4 lbs of boost.
Should I look for a higher quality IC that has a known, lower pressure drop? Should I run a smaller IC than what I currently have, 12x24x3? This intercooler was bought from ebay back a few years ago and i really dont recall what the pressure drop was...

First off you'll pick up power with the Brute speed cam over the ZO6 cam. I went from a aftermarket cam (forget specs I think it was 230/233) to a zo6 cam and lost over 30 rwhp. Try to do a flow test. It sounds like it holds pressure but doesnt flow. I'd pull the I/C off and check inside for a rag or something as said before. The problem ovbiously is in the intercooler. I run a 24x12x3 and I dont have any problems so its not the size.

Back for more guys... A buddy of mine let me borrow his brand new Precision intercooler that is 24x11x3 (almost the same) to see if that would fix the boost issue. No luck there either, it feels a little more peppy but it only gets about 4lbs which is about the same as my off brand ic.
So does this mean i need a smaller ic? Remember, deleting the IC out of my system achieved 8-9lbs but with it kills the boost.
BTW, i ordered t-bolt clamps so those will be here on Friday i hope. I dont think that is the prob though but its worth a shot.
This is getting frustrating!

What's the pressure drop across those intercoolers? Can you tap a boost gauge into the coupler at the inlet of the intercooler to find out how much pressure it is building? That will tell you how much you're actually losing through the IC. Could just be that with as slow as the supercharger is spinning with your 6 rib setup it just can't force enough air through.

ill have to try to rig something up for a boost gage reference on it ic pipes.
I have also checked the system with and without the bypass valve, disconnected, and also replaced with just a 3" bend...

Wanted to bring this thread back up to update. I found that issue was my front mount intercooler. while my IC core measured 24x12x3 it didnt flow a very high CFM through the horizontal unit which they are known for, it was only 750 cfm.
I ended up buying a vertical flow intercooler which flows almost 1500 CFM which is double the horizontal and will sufficiently flow the D1SC. The core measurements off hand are 25x6x3.5...

Yeah, I forgot that part I guess. I havent gone WOT in the upper rpm's because I need to get it tunned since ive swapped from the turbo setup.
rolling onto the throttle I did achieve about 7 lbs, my gauge is measured in bar and I hit .5 bar. I do think I will see a little above 7 lbs once I let the rpm's increase...Now I need to clean up my IC piping and remove some silicone bends before the tune.
