MPIII power gains?

Has anyone with an MPIII actually attained anywhere near the claimed power gains ? On the MP site he shows a 10% od MPIII making 303 rwhp on a relatively stock longblock,stock intercooler and stock exhaust manifolds.Ive read about Kevin L. so Im more interested in the average SCer who has one.

Ive looked through a lot of the member car profiles and I havent seen any stock longblock cars making 300rwhp w/o an autorotor.

Im not trying to prevoke a flame war but Im trying to reconcile a disconnect between what Ive seen on the MP site and what Ive observed in the member car profiles.

I know that someone ran a 314 hp number with a cam and stock heads running 15% overdrive with a double intercooler and a tune.

Just went to Mpowers site and I'm guessing this is what your refering to?:


Below is a dyno chart showing a MPII and MPIII on a Ford Super Coupe with a stock intercooler, stock cam, and stock heads except the "hump" in the exhaust port removed, stock exhaust manifolds and a 3 1/2" exhaust pipe. The bottom line is the MPII running 10% overdrive. The middle line is the MPIII supercharger running 10% overdrive and the top line is MPIII running 15% overdrive. The bottom three lines are boost pressures, setup and tuned by Travis at Fast Specialties, 1-360-213-2781

Result summery:
MPIII @ 15% total OD (10% SC & 5% JS): 317 hp 373 torque, max boost 16 psi
MPIII @ 10% total OD ( 5% SC & 5% JS): 303 hp 348 torque, max boost 15 psi
MPII @ 10% total OD ( 5% SC & 5% JS): 275 hp 305 torque, max boost 12.4 psi

They also show Dyno Charts, so I would say yes its relative...

This is probably a dumb question but wouldnt the comparasion be more valid if they ran both the 2 and 3 at 15%. Seems like they are comparing apples to oranges.
