From what ive been reading, the Magnum Powers blower comes with a 2.70 pulley, im guessing it smaller than the eaton stock pulley, isthat correct ?, what would my boost be at with the 2.70 and a 4lb lower ?. I have a stock bottom end so I want to keep it around 14-15 psi, that should be safe right ?.

 

The Magnum Powers Blower does come with a 2.70 which a Eaton has a 2.93 stock. With a 4lb lower you will see in the ball park of 15.5 psi no headers and 14 with headers. This will be a very safe set up for a stock bottom end. The Magnum comes on much softer like the Eaton but then pulls very hard up top. Not quite like a Kenne Bell but it really has some power in it.

There are a few guys here with the MP and Stock Bottom End maybe they can chime in.

I'm about to do the same thing...that is, put on an MP blower and have a 4lb lower with stock manifolds and a Magnaflow catback.

I've been thinking about either losing the cats (off-road pipe) or doing a high-flow cat setup to decrease the backpressure some and drop the boost. I don't want to do the LT's yet due to cost, but may end up doing them down the road a bit. Hopefully with stock manifolds things will work out OK. I'm putting in a Dynojet Wideband Commander to keep a good eye on A/F and will be getting a good safe tune to keep things in check.

 

Theres a group buy on NLOC for the Longtubes and hiflow cat/ Midpipes

The dynojet wideband is supposed to be the shizznit. VERY Accurate!

i have a magnum

it was easy to install

the power is there

i had a dyno before and after although conditions were completely diffrent.

before magnum= 40 degrees 6lb lower and race gas 100 octane,on race tune = 385 hp


after magnum= 95 degrees 4lb lower 91 octane street tune
=401 hp

the elevation is over 3000 feet above sea level here so hp #'s are probably lower than you would expect

magnum= nobrainer

i have taken advantage of the group buy

 

Sweeet. Can't wait to get mine put on.

Do you have stock exhaust manifolds or headers? What kind of boost are you seeing?

 

stock manifolds for now

ordered the group deal on the headers from jdm


the boost is impossible to measure on stock gauge


its like if you wieghed a 1000 lbs and tried to wiegh yourself on the bathroom scale

 

lol...I've heard the MP has a nice blower whine to it as well....how would you describe it?

 

WHAT I CAN'T HEAR YOU

 

Now you really have me anxious

Did someone say Magnum Powers?

 

 

I have the MP with a four pound lower and I'm seeing a little more than that.

What mods do you have and how much boost are seeing with the magnum powers ?.
