All the bolt on's- +15rwhp and +15rwtq to 150rwhp and 175rwtq
Stroker(+15%)+cam(+7-8%)+head work(+7-8%)- 195rwhp and 245rwtq
Dynojet reads 10% HIGHER than Mustang Dyno.

Drivetrain loss-
AW4 4WD -29%
AW4 2WD -26%
5SP 4WD -24%
5SP 2WD -21%

awesome thread. I considered putting my jeep on the rollers, but it'd be hard to get a clean 3rd gear pull and honestly i'm leary of it going how many hundred mph 3rd tops out at. it has a funny wobble somewhere in the drivetrain noticeable only when going from a dead stop. i'm sure it'd chuck a ujoint or driveshaft on the dyno knowing my luck.

I always thought the AW4 was really ineffecient, especially compared to a manual. Interesting to see how most mild turbo setups make about the same as strokers

CobraMarty

Is that good or bad?

My son rode in Gradon's stroker 5sp 2wd and our M62 auto 2wd feels faster.

I would guess the blower motor makes better low end tq. not saying yours isn't, but torquey motors always feel fast(er).

Damn, I didnt really know the rwhp levels were so low, even on 6psi!!

Great thread though!! Looks like opening up the air path for the motor is a pretty worthwhile improvement.

Stock 190 crank HP / 230 crank TQ doesn't start with much out of the 4.0L
losing 25% due to the drivetrain on way to rear wheel power
