Lightened ring gear, riffle drilled and star flanged axles?

Todd Geisler · 12-01-2015, 12:15 AM

If your looking to refine the combination and get what ever gains possible, then those things are well worth trying for the little cost they ad at the time of purchase.

Star flange axles, I assume you mean Moser. Don't care for them due to rather crude machining and lack of attention to detail. Strange and Mark Williams do a better job in that area.

That said, we have a customer with an Outlaw 10.5 car that had Moser 40 spline gun drilled axles withe star flanges that never once twisted or broke an axle. Car ran 4.0's in the 1/8th at 2700 lbs and 60' 1.00 on a regular basis. So strength is not a concern.

Back to back testing, I have not and don't know anyone who has.

IMO If you need to get weight out of the car this is an excellent way to do it.
Also if you'd like to move weight around what better way than to turn unsprung weight into sprung weight.
The lighter the unsprung weight the softer the shock the better and more consistent the bite.

That's the way I look at it.

no ET between lightened ring gear and standard in my 3144 lb. Super Stock car with Mark Williams Ultimate Hi Torque gun drilled axles, and aluminum spooled "Pro Stock" 3rd member.

Thanks,... I think my money would be best spent on a metric, over the th350..

I do not know how to search past posts, but this was gone over extensively on this site at one time.

I believe the concensus was no noticable difference

I did do back to back test on steel (13#) vs alum (10#) driveshafts, zero improvement. In my case, I have a pretty low HP high RPM combination so if anyone would improve, I would have thought it would have been my car.I also have all the lightweight rearend parts. I really don't think there is any performance difference in any of it. That being said, if I were starting over, I would buy the lightweight stuff anyway. It just seems that intuitively it is better to have the lightest rotating parts regardless. At least it gives you the opportunity to run lighter or put sprung ballast in the car if needed.

Diameter has a big effect. Ten lbs flywheel weight has more effect than ten lbs crankshaft or driveshaft weight. Axles? I can not imagine seeing anything. Another one of those "it can't hurt" deals.

I use to run a 11 pound aluminum flywheel in my 4000 lb 68 Impala 396/325. All the "experts" told me I needed to run a 30 lb flywheel to get that Chevy moving. Never had a problem with light flywheel. Car never bogged, left pretty hard. The "experts" most of the time were guys who ran Automatics.
I also use rifle drilled axles, star flange too, same rear in my 65 Impala now. I felt for the little extra wht not. Just my 2 cents.
