Very cool, sorry about the mis ID. Got any pics of the road burning monster?

I think you mean me! Yeah that was a trial fit up. Yes I have it going . It boils tyres at will. I am going to fit a 3,9:1 diff, and some bigger rubber too. The torque is brilliant!

Hey Blown210, I have been staring at that pic for a while now and just realized theres no belt hooked up. Also no hole in the hood! Did you ever get it running?

remember, a blower will produce more boost on a smaller engine if driven the same on a lower boosting larger engine. say you use a 50% overdrive on a 3.8L commodore. the engine might only see 4psi boost and the SC be spinning at 9000rpm internally. if you used the same pulleys on an A14 for example, so the SC was still spinning at 9000rpm internally, you might end up seeing 12psi of boost. this is due to the engine's ability to inhale the +ve pressure. the 3.8L V6 can inhale more air, therefore consume more of the available manifold pressure - so it might end up being only 4psi or so above ambient. the little A14 might consume a third of that available air, so would theorectically triple the manifold pressure - or 12psi. each system is a little different though, and it depends on plenum sizes, inlet piping lengths, intercooler sizes, cam profiles etc etc but that's the (very) basic principle behind it. just remember to keep the SC series 'chargers under 11,000 rpm internally. they'll last a long time, and won't de-laminate the rotors.

ingenuity versus web-dweebs
 It's also the Datsun owner's can-do attitude. Instead of "My Mom will kill me if I break her shopping car"...

Thanks for the explanation. I'll probably not overdrive my blower 50% as planned. I'll start it out 1 to 1. I have no intentions of making more than 10 psi. of boost. My drive belt will be a toothed belt, but somehow I don't think it will creat much of a whine. After all, it is a factory timing belt, and they don't whine unless you overtorque them accidently.

My blower does not make as much whining noise as you would think (or as I would like). This is mostly because of my drive pulleys. The toyota s/c units use a pully like a a/c units one. the real big angry whine that Jimmy huffers produce is mostly the sound of the big toothed belts forcing the air out of the pulley teeth as it is pulled around. because of the cheap air cleaner ther is quite an induction howl, but not really a whine as such. the ratio of my drive pulleys is 1:1. I figured that thid would be a good starting point. Feral posted a formula regarding ratios etc a while back. According to it my set up should make 16.7 psi????? This is really more that the blower is meant to create safely. It makes a bit over 11 at the moment, but my boost guage is a bit iffy, and I keep running out of road/traction. I know a guy who is running a 4AGZE which has pulleys that are suposed to make 18psi, and his blower is smaller than mine. You blower should be easyer than mine to conceal as it is longer. Mine is a short unit,so I had to mount it forward more to get the pulleys to line up.

Thanks for the info. I found the pics. Bart did a great job on the install. I will follow along with your progress. Maybe you would consider making a kit once its all sorted? I'd also like to get it under the hood so it'd be a sleeper.
