Actually, They break the hardened shaft on the inside of the diff as well as the stub shaft.

I have only seen one halfshaft break on a C5 and that was a 7k sidestep with a dead hook.

OT- Nice work Tony! Thats flying for the terrible air

Damn good thing too! Not sure if your ego could handle getting smoked by a 7,000 lb Crew Cab Duramax and absolutely embarassed by a 6200 lb Crew cab 6.0 in the same day!

Tony, what was your MPH before the AFR Street Heads? Nice run, little soft on the launch but of course any harder and it would have been on the trailer earlier!

My BEST MPH was 110.8 with my bonestock LS1 shortblock including Kooks 1.75 Longtubes, Vortex Airbox, 1.8 Rockers, 2.5" X-pipe (stock Cats), Flowmaster "catback" and the plastic MAF ends which reduce restriction. I had the same 3.90 gears at the time as well. BUT....this run was at LACR and the D/A was 4800-5000 feet. By the way, SAE corrected in that exact configuration my Vette was making 350 RWHP. Again, considering the weight of the car and the elevation, the trapspeed was pretty good considering the power it was producing at the time. My guess is if I were able to take that exact same situation and fast forward it to Bakersfield on Dec. 4th 2004 two things would have happened.....the car would have trapped between 114 and 115 and I would have gotten a ride home in a flatbed

Tony, that is some great MPH with a stock shortblock and n/a. Sorry to hear about the parts breakage but you now know the weak link.

Wonder what that setup would do in my sub 2900lb conversion ?
130mph n/a?

Tony did you break the differential case? Have you looked at DTEs rear end and trans brace?

Tony Mamo @ AFR

iTrader: (13)

The car already has a "built" rear (hardened driver's side output shaft, heat treated ring and pinion, etc.) and I recently installed the DTE brace as well (which helps prevent the case from flexing and cracking). The only part in the rear not "upgraded" which we speculate has broken is the output shaft on the passenger side of the car which connects to the ring gear. That part has only become recently available to the best of my knowledge, although till I physically take the driveline out of the car (I was too disgusted yesterday to start taking it apart AGAIN), I am only speculating that is what broke.

When I get back from PRI next week I will take the car apart and see exactly what failed. I will keep you guys posted.

Regards,
Tony

We will soon be offering billet input and output shafts for the C5 so let me know if thats what you need maybe you could be one of our firsts.

Good results Tony. Sure would be nice to see what AFR heads could do on a full-blown track car running at a sea level track.

congrats!

You might want to consider lifting straight up off the clutch as fast as you can vs sidestepping it. It'll make parts live a lot longer and you'll sixty the same or better.

Tony, did you see my PM?

Nice results Tony, 110 for baseline mph is very much average.

It would be interesting to see what a set of those heads would do on a strong drag setup like 01-Z's, maybe a contender for fastest stock cube car on pump gas.

iTrader: (9)

I'd hate for 01-Z to mess up his record of fastest stock heads. I'll be the stock bottom end race setup to see how they do

Tony, please get back to me.

I've seen H/C vette run 10.5x's many times with mph 130+.
To answer an earlier question, vettes break output shafts, gears, tranny, clutch often during serious drag racing.
