back in 96 they made 240hp if im not mistaken but i dont know about the torque so i guess those #'* would make sense.

No, that * what I have at the tires, not the flywheel.

the pulley is the single best 'feel' mod you can do, but those numbers seem high. You should have started with 240/280 hp/tq.

Do you trust the dyno you were on?

That sounds about right if this is the same guy who has run the 1/4 in 14.0 @ 97 mph.

And yes the the 3.4" pulley will make some awesome power increase over stock. About 30 hp and 50 ft-lbs of torque over stock.

I have a 02 SSEI Bonne and I recently had it on a chasis dyno. With only a 3.4" pulley and no other mods, it makes 250hp and 330 lb/ft of torque at the tires. Has anyone heard of these numbers before with such simple mods?
No, because that is WAY high. The highest I have ever heard of with a 3.4 is 227hp and I think 305lb/ft. That dyno basically HAS to be off.

No, that sounds about 25-30hp HIGH of what it should be. That is more than 300 crank horsepower, and over 400lb/ft crank torque. That dyno is definately off. Yeah the pulley gains about 30hp, but that is CRANK HP, not wheel. Stock HP at the wheels should be between 190 and 200, usually around like 192-195, and torque is usually somewhere in the 250 range (GM underrates torque horribly) at the wheels. So then add in the 30hp for the pulley, that would be about 25 wheel hp, assuming all conditions are perfect and the car is getting no kr, and if it was a high horsepower engine to start with and was making 200 @ the wheels, add the maximum of 25 for the pulley, and you are at 225hp @ the wheels, which is 2hp shy of the HIGHEST 3.4 Pulley only dyno I have ever seen.

That is what I am saying, I am pretty sure that dyno is off quite a little bit, maybe that car is just a freak, but I highly doubt it is even possible for it to be that much of a freak. I don't think our SSEi would even pull those kind of numbers on the dyno.

Did a 2nd pull on dyno and car pulled 238 hp 301 lb/ft. The torque sounds more correct according to you guys, but the power is still well up.

Those numbers are closer. The torque is probably about right on, but the horsepower is still a little high. It is possible that it is that high, but I would go to another dyno and get the numbers verified.
