UPDATE: Over the weekend, I had the chance to re-dyno the caddy after the intercooler install. I felt things went pretty well. On the first two runs, I ran it exactly as I did on the previous dyno session (15 psi..."daily tune"), so the only change was the intercooler.
I ended up with 95.6 hp at 4425 rpm and 135 ft/lbs of torque. I was pretty satisfied... overall a gain of almost 12 hp and 15 ft/lbs at the wheels just by adding the IC. I'd say it's doing its job. The curves are similar but the top end is definitely stronger.
On the last run, I turned up the boost to just over 17psi and turned the fuel up just a bit. That last run netted just
over 100 hp and 141 ft/lbs of torque at the wheels. Overall, that's a gain of 16hp and 20 ft/lbs of torque over the previous setup with a little tweaking plus the intercooler.
I was pleasantly surprised at the torque number. Figuring in the drivetrain loss, it's possible that it's putting out close to 160 ft/lbs of torque at the crank. Good progress. Next step is to pony up for a Giles pump...
Wow!! Very nice numbers. I hope someday my engine will make that kind of power.
I guess I need to get it running first though. Does anyone have a Jetta TD exhaust manifold for sale? Puh-leeez?

Impressive! Looks like the IC was well worth the effort. Thank you for posting the results.
makes me antsy in my pantsy even more as i want to install mine...how big is yer intercooler?
BTW, a friend of mine says that your intercooler is from a Starion, not a Saab. He has one just like it.

Not sure if you're referring to me or not, but mine is indeed a Starion intercooler. I've been saying that since the beginning of the project.

Check here for details... It's pretty good sized for the application. Fits well and should provide plenty of cooling.

Sorry, I misread your earlier post where you were talking about someone ELSE'S intercooler. :oops:
