The 4T60E is a lot stronger than most people realize.

I don't think that Scott has a stock 4t65 in that car.[This message has been edited by Formula (edited 07-16-2019).]

Doubters can ask Triple Edge Performance. He knows these transmissions backwards and forwards. He can build a 4T65eHD to take any power lever you can throw at it.

Anyone have any measurements on the oil pan for the starter? Tried to contact Furches performance on his oil pan to put the starter there. But haven't got a reply.

After it's been performance built. The discussion understood was regarding stock. The stock 4T80 outlives the 4t65.

The stock 4T80 may be stronger is stock form but at the cost of more weight but the question is it really necessary.? You are pushing a light car. Look at this run on You Tube.
9 second Fiero 2nd run
This is where forum member Darkhorizon (Scott) ran a 9.87 1/4 mile time @ 147 MPH with a completely stock 4T65eHD. To run that ET he must be making 600HP. How much more strength is necessary? ------------------

I went nearly 10s on a factory stock 150k+ mile trans, so it really doesnt take too much to have fun. |

Nearly 10's = low 11's on the stock transmission.
All of his runs in the 9's were on his race built transmission with over $4000 in hard parts. Some of these parts are no longer available like the GM Racing 1" chain.
Just about everyone who is really pushing the 4T65e-hd has $4000 + into their transmission and several have even broken these $1000+ parts.
Most of the guys looking at the 4T80 are looking for a stronger transmission they can leave mostly stock and not worry about fragging a $4000 transmission. It is the same theory with the turbo LS guys. Lots of them are using 200K mile junkyard 4.8/5.3 and leaving them stock, running them to 800 hp, enjoy it for a long time, and when it frags, replace it with another $800 motor and get back at it. A desire to keep the cost of enjoyment as low as possible is key here.[This message has been edited by fieroguru (edited 07-27-2019).]

Seen it many times. You obviously didn't read the comments like I did a long time ago, though.
"4T65e trans with a few good parts to handle the power. Sprayed a 50shot in both hits, first one went poorly due to making a test pass on low boost... Nitrous didnt like low boost as much as I remember it did. Nitrous turns off after I make 10psi of boost. Was running over 27psi on the 9.8 run."
