Impressive results on a mustang dyno! Congrats

Looks good. I would removed the cats and throw on a ud pulley to hit 450.

Very nice! Just a little info about dynos though...I made 10 more hp on a mustang dyno over a dynojet dyno lol

Very nice. As long as you're happy with it, then numbers are just that, numbers.

True because on a Mustang dyno you can make the numbers change based on the calibration.

Impressive numbers on MDyno congrats.
put a cutout on that thing I bet it will gain 8-12rwhp.

Nice numbers. Im looking at getting the same heads. What are the rest of the drivetrain details? auto/stick rear/gears? Thanks

You think he'd pick up that much with a cutout? I guess you're probably right since he's running a y-pipe setup. Let's just say for instance he had true duals. How much do you think would be picked up if he ditched the duals and put two bullets off the collectors?

My car picked up a ton when I switched to true duals. I switched headers from slp to kooks at the same time and it picked up almost 50hp and 50ft/lbs. Does it seem like the torque is low for that setup or is it just because of the mustang dyno?

From my understanding and what I've seen the MS3 doesn't make a lot of torque. But I could be wrong.

the MS3 makes plenty of TQ .... It just so happens that the TQ peak is WAAAY up in the rpm range and a little light downstairs.

Anyone else running this combo?? I just bought the PRC 225cc "as cast" heads with the ms3 cam also... my main diffrence is im running a ls6 intake and am going to be going through a stalled th400... I would love to see some track times with this setup

MikeWS6

Not really sure it will gain that much since hes running a straight pipe setup. I couldnt be wrong though..

Csnell3732

Any more updates with this setup?? Just got my ms3 and prc 225 heads car running waiting to be tuned!😀
