5.3 magnasun anyone?

Txjose · January 2, 2016

Nope, which made me happy because I had already bought an Auto Cal from Black Bear. I saved the Magnuson tune and am currently running a tune from Black Bear

I think i have made up my mind to go with the whipple...they have the highest HP "out of the box" and i love the look of the blower idk the pully on the magnacharger looks funny to me....

Now...... To justify the price...... My girl would kill me..... Then want one for her truck lol

I'll have to go take a look at them.

question..im sure u lost a couple psi with the longtubes did u just keep the stock pulley or did u get a smaller to get it back up? what r u running now around 5 psi?

Explain how you lose boost with headers?

Headers flow more air out.... Since boost is just restriction you allow it to escape easier. You dont loose power just boost.... Since its pressure.

Thats how it was explained to me.... Never had anything boosted before so i can not comment from experience

I had a 02 ford lightning full bolt on truck 440/515 at the wheels..when I put full exhaust on it lost 2 pounds and I was curious if these motors lost that much with longtubes. really don't know how to explain to u why it happens..i would guess as stated above the less restriction from the longtubes flowing so much better the blower is not able to build the normal amount of pressure(psi) with the stock pulley because the difference in flow between stock manifold vs longtube.

Ok so the header efficiency allows you to run more boost...I guess how much is based on engine build and VE.

I dont think thats how it works..... Lol

Remember an internal combustion engine is ultimately an air pump. Boost is a pressure caused by trying to force more air through than the engine can pull naturally. When you add headers, the engine is able to pump more air naturally so for the same total air flow into the engine the blower won't be forcing as much and boost will actually drop. That in no way shape or form means less power.

Wider LSA camshaft to compensate boost level 112-116 LSA?

This is my dyno from yesterday with a 6.2 Whipple set up with a stock air box and stock manifolds.. just Cat Backed. I am having 2 inch custom American Racing headers, cold air, catch cans with a new custom tune don't today. Notice the Boost PSI readings with stock manifolds and air box. I do not intend on changing pulleys to increase boost so my new dyno on Wednesday will tell the tale.....

Oh man that is awesome some dead straight up undeniable results!!

Looks like I need to take a few days off and head up to Phoenix and find a dyno. I'm curious as to what my truck is putting out now

Our dynos are out in Lake Havasu, if you are ever up that way and want to get a few pulls done.
