Ghost-Sky Wish you all the luck with you engine swap, it is really cool. I wish I had that knowledge. My dream would be an all aluminum 3.8 V6 with twin turbos.

roust84 I don't know how to embed youtube videos on the forums here but here is a video of a dyno pull and one of the idle just for fun.

Elff That Dyno run looks really good and your numbers are on par.
For example The Dodge Challenger 392 HEMI® V8 engine has 485 horsepower, 475 pound-feet of torque.

roust84 Better late then never. Finally got it to the dyno.
This is the second iteration of the build, after I blew up my first trans and gave up on the MSD I was using originally.
Currently running Holley Dominator ECU.
I am not sure what is going on with the HP numbers. I would have expected it to climb another 40-60 points over the torque numbers, but that didn't happen. MAP load was slowly trailing off, so possibly exhaust or intake restriction. I'm over it for now, so this is how it shall be for the time being.

It did and it was. The 3800 in the Buick GNX (and Buick Regal T-type...and the 1985 Pontiac Trans Am Turbo...both of which are just as powerful but receive far less recognition) was the 3800 Series I. The Supercharged version in the 3800 Series II and Series III are direct descendants of that engine.

Sadly, the Series I is very different than the Series II and III and many of the aftermarket parts they make for the Series I (like heads) will not work on the later engiens.

We would have got a lot more out of it had I had the time and money to finish it right.

Hell, at that point bring the intake right off the back and put a big old butterfly throttle body up there!

In 1995, I had a 1990 Olds Toronado Trofeo (like the one below) with a stock 3800 V6. I purchased a 3800 series 2 supercharged motor with 34k on it at the local bone yard for $1500.00. I paid a repair shop $300.00 to swap motors and an auto electrician $500.00 to wire it and adjust the timing. That car was/felt really fast.

Well, I cut out the bump and welded a 1/8" thick plate back in its place. I hope it'll be enough clearance.

roust84 Helios,

I believe it was part number 12635649. It should be the pulley for the CTS-V
