• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

supercharger find



^^That.

They were horrid blowers that required sub 2.8" pulleys from the factory to make power. They tossed those on the LSJ's and I guess it worked...but there was a ton of work done to them too before they reused them over 10 years later.

And the Rivvy, the Park Ave...basically anything with a pregen supercharged 3800 Series I...

L67 Supercharged

The Series I Supercharged engine went through many internal changes and the horsepower changed rapidly between the time it was introduced and the time that the Series II L67 was introduced. The M62 supercharger was manufactured by Eaton, exclusively for the GM 3800 engine. HP was rated at 205 for 1991-1993 engines (models vary), and 225 for 1994-1995 engines. The additional horsepower and strength was gained by using six bolt main bearing caps, a roller camshaft, semi forged bottom end, larger throttle body, roller rockers and epoxy coated supercharger rotors, improving efficiency. The 1994-1995 utilized a 2.85-inch (72.4 mm) pulley versus the 2.55-inch (64.8 mm) pulley used on the 91-93 supercharger.

Applications:

1991-1995:

* Buick Park Avenue Ultra

1992-1995:

* Oldsmobile Eighty-Eight LS, LSS
* Oldsmobile Ninety-Eight
* Pontiac Bonneville SLE, SSE & SSEi

1995 Only:

* Buick Riviera
 


been in a 95 ultra, not necessarily a slow boat.

Also consider the M62 used now is a Gen V blower, not a pre gen III or whatever was put on the car back then.
 
Yea they have the usual changes like the different intake design, better outlet, and the abradable coated rotors. They are not the same as the old ones. The only thing they share is flow rate.
