Will an FLT or PerformaBuilt 60/65E hold?

my trans handled the power i put at it for a while, and after a year of countless runs the converter finally broke so as long as you have a good converter i think you should be ok for a while. when i pulled my trans apart it looks good for the abuse it had .
running an 11.9 on 22's and weight of over 5300 lbs, id say thats at least 500-600 at the wheels.

That's what I was figuring. PerformaBuilt says they'll have a level 4 65E coming out in the next couple of months. No indication of the power capability that'll handle that I am aware of yet though.

you were only th 2nd person to mention 80E.Anyway...

You could do like Ben and have better lines and fix the length issue of swapping to an 80e. So with all that done you are still below the price of a fully built 65e and its stronger. You cant deny the strength and you know when you get it up and running the urge will be too strong to up the shot. Do what you will with the info I have given you but in the end you are going to have to go to an 80e anyway might as well do it now IMO.

Hey J,
I ran at those power levels and am the reason why Chuck decided on the 500hp limit.
During the time we were experimenting with the 65 and big power, I ran two essentially (had 3 but one was taken out in the first week due to manufacturing defect in the converter / install error). Of the next two, they performed very well, but what we learned is simply this: the reliability is shot to hell. I don't mean the reliability of what Chuck and Vince can build up -- those parts never had an issue in my trannies -- it was the other stuff -- the sprag was the last one and it broke while the truck was in de-tuned DD mode, and with no power being applied (literally sitting at a stop sign 1/2 a block from my house).
[edit: even so -- Chuck told me to continue to run the 65E I should plan on letting him refresh it once per year]
I did run 0 TM, but don't believe that was a contributor as my tranny failures were not to the performance parts. I ran detuned a lot (no biggie here, don't need 750 awhp to drive 5 miles to work in 35mph zones lol, but a hassle none-the-less). I had to constantly watch the tranny temps, and in the summer they were a concern almost everyday. We kept it under 200* when possible (sometimes sitting in traffic, that wasn't possible, and resulted in the first real failure). I was running a big tranny cooler and efans.
Basically what I'm saying here is this: You've got a few choices: 1) run 700hp and roll the dice every single day to see what random **** might take out your tranny and converter, 2) bite the bullet and put in an 80, or 3) detune your expectations and stay below 550ish (which is still going to push the reliability issue).
My advice if money is getting in the way, get a junk yard 80E (go talk to Mater about a low mileage one) and put in a shift kit, do your installs, run it til it breaks, let Chuck rebuild it.

I really don't want to drop $3k on another FLT just to turn around and have to go 80E. I guess I have another project to add to my list
