I have a 1999 with the 3800 engine. The owner's manual says the horsepower is 205 without the supercharger and 240 with the supercharger.
The Buick Riviera with supercharger should put out 240hp
by using a supercharger u get 30 to 40% more horse power than when compared to an engine with out a supercharger....
Add an aftermarket supercharger.
The power steering box is on the right side behind the motor close to the finder wall. Get a flash light and look behind the motor and don't try to reach it while the motor is hot.
240-260 horse power stock, supercharged. Buy a smaller pulley for supercharger add 30-60 horse power more.
what are you takling about? no such thing!
No
350
The belt drives the power steering, water pump, and other things.
I have been wondering the same thing, I have a 98 and I have been looking around the junkyard, the supercharger itself would only be $70, but I believe that there is an extra pulley on the Ultra that powers it. I have heard that the Buick tranny is not built to handle the supercharger and needs to be replaced about every 50k miles. Giving the car the extra power may cause other issues with valves, heat, and reducing engine life. I am going to look into this further by comparing the repair manuals, and hopefully try it out. Not only is a matter of the tranny being able to handle the power, but you do need the extra belt to power the supercharger. That would be the least of your worries. You would need to recalibrate (if not change) the fuel system to accommodate the increased air flow through the engine. Not worth the effort or cost.
One way to gain a significant amount of horsepower in the 3.8l is to add a supercharger. For example, the RIPP supercharger made for Wranglers with the 3.8l.
