Are any of your units being used in the copo's in stock eliminator ?
I thought the factory ones came with a 9 inch ? Unless somebody was scratch building one
What are you thoughts on the hp drain from straight tube to IRS

Thanks Rory

Rory, if our Tom's differentials IRS I using up any horsepower, it doesn't seem to show it in 60' or in mph. The 3x2 combo is a little soft across the middle, but the mph is all there. Last week in bowling green we were consistent 1.42x 60' with the rear wheels. The car hadnt been to the track in almost three years, so it was a little slower than it should have been, but a 10.53@129.77 doesn't look like the IRS is eating too much hp.
