With a m112, headers and a 3.0" pulley, you will see 6-7 lbs of boost and (around) 500 rwhp/ 500 rwtq. If you run the stock 3.4" pulley with headers, you will make less then 5 lbs of boost. From what I've seen and heard, I would not run smaller then a 3.0 on the Magnuson 112......if you want more boost or power, I would buy the M122. The new larger m122 will make more power, maybe a owner will post (there's very few out there).

No, you don't have to change the pulley. You will only see 4-5 lbs of boost if you run headers though.

I have a Maggie 122 with a comp cam and Dynatec 1 7/8 headers. We changed the 122s stock 3.6 pulley to a 3.2 pulley. It makes 7.5 lbs. of boost and 585 rwhp. The 122 is .800" longer so you will have to modify the rear cross member of a RK Sport hood to clear its extra length. The 122 is a full 2 liters so it does flow more air at lower temps. and in so doing produces more hp. I have had mine for over a year now and have had no problems with it other than I have no traction until 4th gear even with 345 PS2s. That said I would do it again this combo is so much fun to drive. It drives almost like a stock Corvette and gets great milage until you hit it then hold on because all hell breaks loose.
