You may be right...I dunno. He sure has my curiousity peaked though....LOL.

I would like to see just how much H.P. gain you get at each RPM range. I tried to copy the pic and enlarge it, but had o luck.


Rocks


I would also like to see the A/F lines. When I try to enlarge the pic, it looks like one of the lines is riding pretty high above the other....but I can't tell what color line is what...

 

So looks like the MP is not worth the money, if it is being ousted by a ported blower. What's ironic is that the Apten and MP had a lot of the same folks involved in the development process....

 

not to fast!! The MP is know to go 22+psi more efficently than the ported eaton. Higher boost is yet to be tested but i am biased as i have the port and am glad i am cheap for my 12+ lbs of boost i am sitting pretty .

 

Any chance you could do the same test on the same truck with a KB blower?

 

True, but a stock block won't handle 22 lbs. of boost for too long. Most who go that far will end up with a built motor. So if you're spending big money on that, why not take full advantage of it with a KB for only $800 more?

 

Valid point so that pushes MB out??

 

Good test!!! The only thing I'm wondering is would the 2 blowers have different results on stock block trucks?? I've personally seen an MP stock block truck make well over 500RWHP, but then again I don't know how much boost they were running!!!

Thanks for doing this test for the community!!! Good post!!!

 

Can you buy KB's for $2400???

 

15# of boost... Remember i truley believe the M/P will outperform the apten once we spin it up more. If you look close at the graph you will see the M/P started to make more power @ the higher RPM level. Where the apten started to fall off! So no doubt once the M/P is spun faster it will make more power.We @ JLP are in no way downing the performance of the M/P blower, we were simply conducting a test...Let the results speak for themselves.We will be testing the M/P at a later date with a larger lower pulley and a 2.7 upper!....JL

 

Whoops, for some reason I thought an MP blower with new rotor packs and everything was over $2,000? Sorry if I was mistaken. Still though, the price difference is nominal in my book when you're looking at the kind of money required for a built motor, upgraded fuel system, new tune, etc....

 

@ 17 # of boost!

 

another valid point i guess i'll buy one of each and do my own testing............or not LOL! will it ever end??

 

To all,

I will be willing to ship my pulley to JLP, PSP for testing if you all would like?

I personally saw 24 lb of boost at 3300 rpm on the dyno at JDM
we stopped at 3300 rpm's due to a dangerous lean condition.

Believe me the MP pulls harder at about 3000 rpm's. The truck seems to win more races after the 1/8 mile than off the line.

I do not have cams by the way just some hollowed out heads with 1MM over sized valves!

I have been off and on the phone with Charles from MP all week. We are going to be doing some testing on a local customers truck very shortly. I have a new MP sitting here waiting to go on. We are working with Magnum Powers to see if we can figure out the sweet spot of performance for these blowers. As has been already stated, the MP really shines at very high rpms. This is not a blower that is made to be used with a 4 or 6 lb pulley and stock size upper like the ported blowers work best with. It's made to work best over 18 psi. We are going to test one on a truck that's got an 8lb lower and 2.7 upper on it now, with a ported blower. We'll do a real before and after test and see how the MP performs. Having experiance running the Works 112, which worked on a similar pricipal to the MP, I am confident the MP has a place between the ported Eaton and a twin screw. We'll find out soon .

 

Sal, the offer is extended to you also Amigo! If you would like I will ship my pulley to you.

I will do any thing to help out MP they have been my life support for almost 2 years now.

One other thing the truck that the blower was tested on had cams on it right? Doesn't cams determine where the power will build also? My truck had stock cams with ported and polished heads and intake and 1 MM over sized valves.
