I have a P-1SC with 8 lb pulley. I called ATI today and they do make a 10 lb pulley which I am willing to buy, but I am in no mood to remove the head unit to swap the pulley. Are there any other ways to get more boost, if so, how much?
The reason I want more is with the head and cam I have I only see 6 lbs at the motor and I could use an extra two.

 

The only thing that may increase boost (other than a pulley change) is to improve the air intake tract with a solid intake tube (possibly moving the MAF to the pressurized side and going to a 4" intake tube) and a larger air filter.

It's really not that big of a deal to swap pullies. I'd be surprised if it took you 2 hours. I'd guess about 1 from start to finish.

Jack car up
disconnect air intake, outlet
remove belt
pull head unit
swap pullies
put it all back together

 

Nitrous?....

 

Bad 97, just pull the unit and swap the pulley..... Silly silly.

You could do 3 things: use a smaller engine, use a set of less flowing heads or use a smaller camshaft. Or you could change the pulleys and or maybe rev the engine higher.

 

Last time i did a pulley swap I didnt remove the head unit. But if you have to its only what....4 bolts.
