Whipple + Drag Radials = DS suicide
Well, I went to the drag strip for the last weekend of the year in hopes of finally taking advantage of some good air (finally!). First run was 10.90 but at a better 130 MPH thanks to the new Griptec 3.50” pulley and 250 DA (https://photos.app.goo.gl/9V5UipNQDWVeNLSk8). With a very soft launch and crappy 1.79 60’ time, I knew a 10.50 was a possibility if I could improve my launch. I figured with a stock motor, stock manifolds, stock cats, and 20” wheels, that would be damn good for me. So I launched Full Send on the next run and it hooked! Great launch, but 20’ later it was all over with my stock DS giving up the ghost. I can’t believe how small the stock SS DS is by the carrier bearing?!? I was happy that I was running a BMR DS loop though... In any event, I just upgraded to the 3.5” GForce Engineering aluminum DS and can report it is smooth as butter out on the street. Absolutely zero vibrations and saves about 7 lbs of rotating weight too. Hopefully this one will live a little longer than the factory one!

Well that stinks. I had the same thought as you on the driveshaft loop, and went with a BMR when I'd bought a supercharger 'just in case'.

Yeah, I was *really* glad I had done the loop! I did the loop about 2 months ago after seeing my buddies 750 WHP Mustang do this number to his aluminum DS (believe the brand was dynatech? Never heard of them.). I think I’m more bummed out on missing out on 250 DA air than I am breaking a DS...

If you want to get one last fling in this season, Atco Raceway in NJ should still be open this month, weather allowing. A few years ago I went there in my SS on 'Black Friday' (local racer friend had told me about it) and got 3 runs in. NHRA track, so rules should basically be the same as at the Valley.

Wow...That thing snapped off clean. I haven't seen one break there. They usually twist that coupler in the rear and bend the bolts

Well, on the bright side, those Nitto NT555R drag radials definitely hooked!

Man, thats 1 thing I was afraid of when I got my DR setup. Thru an AL Gforce drive shaft and DSS axles in. Always chasing the weakest link! Glad you didnt get hurt and it didnt cause to much damage!

Thanks! Good call on doing the axles too...that will probably be next to grenade if I don't address them soon... The BMR DS loop was a lifesaver!

Something I should think about for next season. So far I havent had any issues with mine. Seems like the A8's that have had DS breaks have been at higher power levels but I havent been tracking this that closely. Missing out on DA like that I would be bummed also.

Jhunsberger, are you still on your original clutch? I wonder which clutch is the best option when running drag radials? When mine gives up the ghost, I'd like to replace it with something that somewhat softens the impact of launching on DR's and is as street friendly as the stocker

Interesting comment. I just installed a 3.5” GForce aluminum DS and couldn’t help but notice how smooth it was? Is it at a particular speed that you are noticing an issue?
