ATS Billet Flexplate can Fail
 

The ATS Billet Flexplate is not unbreakable, I just tore the center out clean no other damage. I thought these were bulletproof, 10,000 miles and around 1 year of use. It was pushing 700hp and over 1500 pounds of torque. I am glad the transmission held up both billet input and output shafts. I replaced with a BD billet Flexplate SFI 29.3 from Goerend transmission. I hope this one lasts a little longer since it is able to flex, unlike the solid ATS Flexplate. I will post pictures tomorrow.

welcome to diesel bombers glad you could join us here at the #1 diesel site out there:yeah:

Guess this proves nothing is "unbreakable", What were you doing when it broke?

Just driving to work, but it has been dynoed at 700hp 1500+ pounds torque, 114mph 11 second 1/4 mile and it is a daily driver, who knows shit happens, nothing is unbreakable I guess..........just FYI for those building up HP, ATS solid billet does not flex

:hi: thats a powerful daily driver you got. :c:

Thats one reason we only recommend laminated flexplates and not billet is because its able to flex. Something has to have a little bit of play in it or things such as this will happen. Hope everything gets worked out and doesnt happen again.

Here is what it looks like after failure

i have been running a sun coast converters flex plate for a year now and havent had a problem i even broke the input shaft with not hurting that flex plate it hasnt given me any problems

Thats one heck of a clean break. ALmost like it was either machined too thin in that area or maybe it was a 2 piece and welded together. We use the BD units in all of our transmissions.

how and when did you break it? i just got one of these and im hoping to be making 8 something here in the next few months..... im just curious cause if it didnt take much to break i will send it back and get something else

I'm with Diesel Nut here.......That looks like the weld or machining was bad. Maybe a coat of that Barney Purple paint would have made it hold up better.

When it broke I was not running it hard, but it has been in this last year run pretty hard raced 114mph 11 second 1/4 mile and dynoed at 700hp, and run hard for testing the turbo setup and all the other things that were done to it. It all is a custom build by Ellis Performance from Chicago area. It was only 10,000 miles approximately and 15 months of time on the flexplate. As for running 800hp I would probably go with the BD Flexplate and it is now SFI 29.3 diesel rated, that is what I replaced mine with and it was recommended by Dave Goerend.

ok man..... thanks and that was a nice break...... did they give you anything back for it?

I have received nothing for it yet but a rep from ATS offered to exchange it for another if I paid shipping, still waiting to hear back from him. If not I have an expensive trophy to hang up in my shop..........

tell em you wanna keep the outside of it..... :tu:

they should send you a new on for free
