Saleen S281 blower questions

[mechanicboy]

My friends stepson has a 2000 GT with a blower that he says is an S281 Blower that he wanted me to change the spark plugs on. I didn't change the plugs because the engine has just been been driven and it was too hot with the blower neck in the way. Anyway, he was complaining of it feeling like stock when I noticed that it had a Steeda crank pulley that looked stock. What can you tell me about this blower and should he swap to the stock crank or get a smaller blower pulley(I told him stock crank pulley but I want to double check).

Thanks.

Depends on which gen blower it is. Does it look like a small eaton? Or more like a whipple?

More like a eaton with the ridges.

They used the M90 Eaton if I recall correctly. You can't push them that hard before they blow nothing but heat. Swap the plugs, and fuel filter. Then figure out what pulley it has and go from there.
