Hah! You guys are too much.

So I got it out for a test drive last night, from the garage straight across town 40mins to my apartment.. runs nice with no leaks or detrimental issues! The wastegates appear to be limiting boost down to 0-1psi up to 4500rpm which is the highest I revved it.. I really just babied it and tried to get a good learn on the base tune for idle up to 3500rpm during part throttle cruising.

The alternator pulley squeals like a pig some of the time it's under load, but not always. The spring tensioner is just dancing all over the place when this happens, so I'm going to try a solid/adjustable tensioner and see how that helps it. I knew this was a risk going into the alternator relocation design, but was hoping it just wouldn't manifest itself.... we'll see how the solid tensioner improves things.

I realized that I've never really uploaded any interior pics, and it was nice and sunny today so I thought I'd snap a few.

I'm still using the stock F-body T56 shifter as I continue modifying and tweaking the McLeod short shift unit.

Briefly in other news, I finally went back and looked at my log from the initial drive home.. it's very interesting that ambient temperature was in the low-60's Fahrenheit, and compressor-output air temp ranged from low-80's up to 115*F.. yet the IAT at the throttlebody was always hovering between 64-69*F. Very interesting how consistent the IAT was, as I know the ambient was pretty cool and I wasn't getting close to boost, but it's nice to see an indication of a pretty efficient intercooler, from those numbers barely varying... hopefully there's lots of thermal capacity left once I get into boost during the summertime!
