So are you guys running a 112 or a 122? What pully are you using and what boost are you getting out of it?
For the 122 people, did you need to get forged internals to pull it off?

George (1bdasvt) and I are running the 112 with a Reichard 3.0 pulley....I'm right at 7 lbs of boost, I think George is 6.5 (he's running a blower cam). From what I've seen, the 122 will make 1 more lb of boost then the 112 (on the same pulley). The few 122 owners I've talked to are all running a stock bottom end. Believe it or not, you won't see big hp gains by installing headers with the maggie (you probably won't see any without a pulley change.....you would make about the same power at less boost). I was told this by Lingenfelter before I installed my headers and they were right. I only picked up 10 rwhp by adding headers and going from a 3.2" to a 3.0" pulley (maintaining the same boost). I did pick up 30 ft lbs of torque (just what the maggie needs LOL). I would still recommend headers though, the car does run better
and it helps to expel the exhaust faster.
BTW: I'm glad to see more maggie brothers on the forum...........me and George were getting lonely.

I'm running Kooks 1 3/4" "had the headers before the Maggie," I,m at 5,000' altitude with the 3.2 pulley and making 5.5 lbs. of boost. Thats according to my trusty Magnacharger boost gauge. Now the fuel pressure seems to stay right at 60 lbs. and never varies. I have only had the Maggie on for about week, but I'm lovin every minute of it. The tune is the canned tune from Callaway, so I'm sure there is some ground to be made up there.They definately are a tire shredder.
