Awesome stuff. Had to let the front page in on it too...

His pulley setup was a 195 crank and 74mm fixed
Not a 77mm
Apparently a turbo setup is on the drawing boards

i've been running with this supercharger from 1 year with 2 bars boost 30psi on my 3.2 v6 engine with 175mm pulley, u need bigger map sensor 2 bars instead of stock 1.5bar, u can use the MB diesel sensor same type as stock plus a programmable voltage calibrator to map the output of the map sensor like the stock one, also u need bigger injectors.

No, 2 bar map sensor with split second voltage calibrator, to foul the ecu, the ecu think i am still using stock map sensor, u calibrate for altitude when ignition on, then for idle, those 2 things are to start from, u read voltage on stock map when ignition on then on idle, after that u calibrate same voltage for bigger map sensor, u need bigger injectors because on high rpm/boost now u are reading lower voltage then stock.
remember i am using stock c32 ecu, but i think is similar to 55k ME 2.8.1 amg both.

I owned an LS2 GTO. That wasn't a car that got walked very often. I'm sure the poor GTO guy steers clear of E's in general after that smack down.
Then again the Goat still had an engine the next day.

This^^^^^
22 psi with our factory blower is insane..........like I didn't think it could be done kinda of insane. I have a simular pulley set up and I'm only pushing 16-17psi (map clamped) with cams, high flow heads and MBH headers. Not to mention true 3" exhaust with no cats and dumps before the mufflers.
Maybe he has factory headers and stock exhaust? That's a lot of pressure.....

I'd think that the blower would heat soak badly too with that much boost, unless these have Really efficient intercoolers. I'd like to see his logs too to see what his IAT's were at, not too mention timing and stuff like that too.
I do know a couple of things though, that I've found that a car runs at its best right before the engine is going to blow up (found that out from both mine and some buddies past experiences) and that his car was Freakin' quick!
It looked like he was launched out of one BIG slingshot! It was a BEAST!
Thanks for the video and I wish that they'd have kept the vid running longer to hear what else was said by the Guys in the Goat. It made me crack up!
