Build a 1200+HP rated 4L80E for under $1200 !!

Автокөліктер мен көлік құралдары

So this is how I built my 4L80E to handle 1200 hp for under $1200.
A shirt I designed for every mechanic - amzn.to/3YxsdB4
Parts used for the upgrade:
A lower cost trans rebuild kit with kolene clutches without extras but cheaper-

A better 4l80e Automatic Transmission Rebuild Kit with Kolene clutches

A better input shaft than what I used for the same price:

Not part of the transmission but I bought a stall converter while I was at it. Here is one rated for 800hp but more flywheel bolt patterns

    Everything in the auto industry is rated at torque (and number of cycles), not HP. You can't use hp to rate anything in the drivetrain. Transmission capacity HAS to be rated in torque, not horsepower. The transmission can live long at 1200hp but break easily in a 600hp car. One will make 505lb ft at 12,500rpm (1200hp car) and the other 1010lb ft at 6250rpm (600hp car) That's why you can't rate driveline parts in HP I'm an engineer in the auto industry BTW.

    I appreciate you taking the time to give a dissertation on this. Those numbers are moot though. Show me examples of the 12,500 rpm engine bolted to a 4l80e making only 505 hp. Seems many manufacturers rate their parts in hp. Torque is easily calculated from hp. I’m a guy who builds cars for fun in his garage and not on a computer screen or a calculator BTW.

    ​@@SOB_Garage I understand what you are saying, and appreciate the reply. I sincerely wasn't bagging on you or your work. I was just giving some insight from an OEM perspective so others understand that 1200hp isn't the same in all cases. I think what I've seen of your stuff is great. If I was to say it simply it's this. "The amount of twist, for how long, for how many times is what matters. HP is not a measurement of twist/force, TQ is." HP is actually calculated FROM TQ. Think of it like this TQ is a hammer blow, HP is how many times a minute that happens. Make sense? Knowing how many times a minute the hammer hits the spike doesn't tell us squat except how fast it will get driven in. (HP) The actual force of the blow (TQ) is what we need to know to design a hammer to take the repeated pounding. You will NEVER find anything in a driveline designed by an OEM rated by HP. HP is a derivative and not a constant. They rate things in TQ capacity and number of cycles it has to take that TQ before failure. The aftermarket is totally different. They are not designing things to last 100,000 miles under warranty. They use terms people are more familiar with like HP to sell product. (Even if it's wrong.) It's more of an educated guess. Most guys who are buying the input shaft in your build will have a V8 (Or possibly a straight/V 6) under boost or a ton of nitrous and produce that 1200hp somewhere between 6400 to 7400rpm. Just like using the formula HP = TQ x RPM/5252 to find HP from a known TQ figure, you can back out the torque from a known HP and RPM figure. So they can guess the 1200 HP motor will most likely make peak torque of 1150 to 1400lb ft of torque between 4400-5400rpm and that's what they use to rate the part "1200 hp". I've done this stuff for a living, believe me no one is rating parts in "hp" behind the scenes.

I blame a lot on the fact the car hooks very well on the street. But ill take a busted transmission over a hurt engine any day of the week lol.

    I guess if you count the stall as part of the trans, then yes it was more. But I don’t consider a stall as part of the trans. Most built trans do not come with a trans - they are extra.
