HIT THE HP WALL
Hey BABolt, have you ever checked into Electromotive for ignition applications, etc?
I'm playing around with a Motec system right now, boy what a mess my L's in now, I've upgraded the fuel rails, new lines, weldon f pump, and the list goes on. Haven't been driving it for almost two weeks, course, haven't had the time to do anymore work on the system.

I'm no expert but my friends mustang runs 41 lb injectors, and he's getting about 700 horsepower at the rearwheels. He also has to huge fuel pumps. Just a guess but maybe the stock fuel pumps arn't big enough. the other guy we race with(mike post) he's running 41lb injectors on his mustang with a novi and he's got to be around 900 horse power with that car, cause he's a full second faster then my buddies mustang with 700. Just my guess at it.
Hey guys bumped into a family friend over the holidays. Seems I continually blew this guys stuff up as a child. The family owns B&M Automotive of the shifter fame! They sold off their blower division last year to Holley. Anyways I showed him the truck and first comment out of his mouth was do you understand how positive displacement blowers work. Of course I said with confidence? Then he proceded to tell me that with every revolution of the blower I get a fixed amount of air no matter how much I try to blow thru it!!! I may have found some of my wall. In his humble opinion we may have hit the limits of the Eaton's ability to pump air??? Anyone ever heard of anyone using this size Eaton getting much above 450hp? In any case I will measure to verify this idea.Food for thought. Hope everyones holidays were great, Chet
I'll take the 450 "On Tap Please"..just to smoke the Plano, Tx punks at their own stinkin' game....Dallas Tollway Racing..yeah...now stopping the Refrigerator....oh ****..thats another problem..
can you spell "Brembo"...."Baer Claw"....etc...

Very interesting proposition from the B&M guy. If his theory or postulate is true, then maybe there's a way to measure if there's way to much air going past the boost bypass valve that's on your setup. My idea may be hoaky; I don't know. But, to me, one way to prove if the Eaton is only letting so much air into the engine is to find some method of proving if a lot of the boost from the Novi is recycling past the bypass.

He's right to a certain point. The Eaton is a positive displacement pump. It takes XXX cubic inches of air and compresses it. But it doesn't care if its XXX amount of compressed air or XXX amount of air at 5" vacuum. It's gonna compress those same cubic inches of air into a small space. So, preboosted air is gonna get boosted more. If you don't think this is right then you've never checked a barometer before going to the track. A high barometer is nature's preboost.

Between Joel and myself we have access to getting the Eaton checked. The pre boosted air will increase pressure but the real question is,is the flow being limited!!! Flow is power which means CFM. Yes you get more flow in most cases with increased pressure ratios but I think at some point your limited with ugly things like temp increases etc.. Joel I need you and REX to tell me how to measure this stuff so we can start knocking down the potential problem areas.GOD BLESS the AIR&FUEL GODS!!!

Give Chris at Magnuson a call. I have spoken with him several times about your project. Just might have an alternative for you.
Post Script!!
I just had to ask this. Chet, you stated and the photos show that you did in fact increase the size of the Eaton pulley thus slowing the unit down. Did you double check you air flow calculations. I do not know what your ratios are for the Eaton and the Paxton pullies so it will be interesting to find out if they are working as a team or that maybe one became a three legged dog.

Could you explain a lil better for me so I will know what you are referring to.
Thanks!
