The computer will take care of KR automatically. Remember that GM won't set these things up right on the edge of heat performance. There'* a safety margin built in. You just use some of that margin. The smaller pulley on the 92/93 (2.25") has been dyno'd to 20 hp. I don't know if that'* at the wheels or flyweel. The main point is that you want to give it the best airflow possible....custom intake, open the exhaust, and do some heat prevention. 180 stat and extra trans cooler, ventilate your sc or intake cover (my sc runs an average of 8 cooler now), and anything else. This can make all the difference. Yes, you do develop more heat. But not enough to keep you from gaining 20 hp.

Default What if...

I have a 1992 Bonneville SSEi with about 146,000 miles on it. If I were to change my pulley to get more HP, would I seriously be screwing up my engine? And if I were, what could happen?

Stef, anything you do to your car can have a bad effect. It all depends on how it'* running right now. Any one of our cars could die tomorrow. Even with low miles. The 3800 has a reputation for toughness, so with this car, more than any other, if you use reasonable mods, and take safety precautions (like preventing heat buildup) you're generally ok. The smaller pulley would only add more stress when you're really getting on it hard. Normal everyday driving would be fine. Save it for that 'special' occasion. I firmly believe that if you take the right precautions to shed some extra heat, you can offset the extra heat the SC develops with a smaller pulley.

Heat is the #1 killer. And we know how to take care of some of that. It can be managed.
