First eaton numbers! - 2003-04 Mach 1 Registry Owners Club

WhippedMach · 09-05-2008, 01:45 AM

So finnally after a year of building the car and working through countless issues finnally got the car 100% tuned.

455rwhp and 515rwtrq with the 4#lower and 2.76 upper.

I think i'll need the manual tensioner or a different pulley combo as around 3800 rpm i start to get belt slip. First couple pulls on street before tune it hit 17-18#/s now my belt is not as robust and it hit's about 14-16#s at the tune. You could really smell the belt burning, I'd like to see over 500 in the hp range. I'll post pic's tmr.

455 and 515 are sweet numbers , once you bet that belt slipping fixed you should be around 500.

Your overspinning the blower with that combo. You need to switch to a 2.93 upper. Trust me on this. The Eaton can only be spun so much. Manuel tensioner is not necessary for belt slip. I make 25 lbs. with the stock tensioner. Do you have the stock idlers still and in what position?

WhippedMach · 09-05-2008, 01:31 PM

Yeah i wanted the 2.93 and ill get on i just got conned into the 2.76 by some cobra guys i'll pick it up after just a while. You can deffinalty smell belt at high rpms. and its all over my pullies.\

As far as the idle i actually bought a full kit from lightning force performance. It had all of the idlers, alternator puller and intercangable upper and lowers it was about a 700$ kit.

I'll post pics when i get off work between 3-5 unless i hit up the track then it'l be this evening. I had the eaton and all the engine components powder coated it's blingin

Either that or add tensioners and port the blower. LOL

Well, I'm definately jealous of the eaton set-up you have. Wish I could do that swap. Why are so many people having problems with belt slip?? I want a supercharger but am hearing that belt slip is the issue. You'd think they would engineer these things better. Is there a kit out there with no problems?? If there is that's what I'm going with no matter the cost.

Just got back from the track Slip is horrible after the initial spike, it was only making 12#'s of boost. The belt was done. With the issue it did run a 11.70 @115 with a 1.55 60' time.

Trust me when set up correctly belt slip should not be an issue on any blower.

WhippedMach · 09-06-2008, 10:52 AM

I would agree i just have way to small of a upper pulley and i'm over spinning it.

^^ I agree. Mine doesn't slip at all. When I bring the boost up I'm going to an eight rib and there still should not be any slip.
