Re: Alternator choices

Jones makes a drive setup with a cog belt for circle applications that run high rpm......I used one at 8400 rpm with no problem ......I've used a lot of their drives,there are 1st quality..........They have an amazing ammount of brackets and drives that will work on almost anything. .....http://www.jonesracingproducts.com/kits.html ..........Tom

Draw and charge concern me, I plan on "topping" off after every round but our logs show us the car is sucking all the juice from the 50 amp nipensendo unit it can make.

So, since I made 3123 with the car I am a little leary of adding another battery (I still need to drop 75 lbs or so from the car) and well.....

But at the same time spending $430 on a powermaster 150 dosent seem great if its going to slow me down more than the weight.

Just looking for opinions here on both a good choice (my bracket are already setup for the denso/nippensendo mini type) but people rework them.

And I never want to slow the car down by "pulling" to much alternator side. Is a second battery or a better alternator the way to go for the amps ?

Whats your volts reading at idle and low rpm? With that small of underdrive ATI damper, buy an overdrive alternator pulley for the proper ratio. Thats what I did.
