I can see why it's not that strong (it's almost like a precursor to the Ford TTB. Wonder if the designer was traded?) On the radio truck, the first thing I would do is remove those rear blocks, put in an angle shim and flip the rear shackle like I did the J4000. (took me 1 hour to swap in the diff and the shackle came down 1/2 way for me. I just used a prybar to flip it) Too bad that design went away in the later '70s. (the shortbox might be that way. I'll have to check today) Going to be looking for a stepside for that one this summer. (6 foot bed just isn't enough for much of anything in the way of hauling. Even my compressor probably wouldn't fit in it!)

I'd be surprised if you could get 2-3 Psi boost out fo this, it looks like a heater fan... :) while this may be pretty lame, I'm wondering if this might not work to overcome turbo lag in an older Diesel... :) I wonder how much power it would really take to use an electric motor as a supercharger... now is a time for the engineers amongst us to show off their math skills, dazzle us with physics and otherwise enlighten us... serious... I know that this gadget is unlikely to be effective, but I really want to know what it would take for it to work, and how much power would be required... Use a 3.0 or 4.0L engine as a base... I would think gas vs. Diesel would matter too???? from earlier thoughts/posts: this is the formula to figure out how big of a carb you need and how much air flow you really need... CFM = (rpm x displacement)/3456 ( 4,000 rpm * 360 cubic inches ) / 3456 = 416.67 CFM at peak torque on an AMC 360 you only need: ( 1,700 rpm * 360 cubic inches ) / 3456 = 177 CFM So the 290 CFM carb that comes stock on the '80's vintage Wagoneers is ok... ref: http://wagoneers.com/FSJ/tech/kn-vs-amsoil-according-to-john.html john ----- - ---------------------------------------------------------------------- Snohomish, Washington -o|||||o- where Jeeps don't rust, they mold http://freegift.com ** http://wagoneers.com ** - ---------------------------------------------------------------------- there's a solution for every problem; problem is can we afford the solution? - ---------------------------------------------------------------------- On Tue, 25 Dec 2007, Jim Blair wrote: # Or not....

Someone makes an electric blower, and it's actually quite effective. As JB says, it's got to move some serious air to do anything. I think it pulled somewhere on the order of 250-300 amps. Pro: no parasitic drag from the supercharger belt Cons: the whine from the bank of alternators has got to be deafening, and the bank of batteries has got to weigh a ton. Can't remember where I read about it, but remember thinking that a powermaster alternator would still fall shy of keeping up with it and require some mildly creative wiring.

That's how *I* would do it, anyway. ------------------------------ End of xj-digest V1 #2713 *************************
