questions about your old drag car and lentech
hey tom. i tried a search and failed miserably so i figured i would just ask in a thread so it could be on record for anyone who wants to know in the future. as you know i am in the middle of a build to make 450whp on pump gas and if possible i want to occasionally push it to 600ish on race gas just to blow peoples minds on dyno days. my issue is with getting the transmission to hold all of that because i would still like to be able to drive the car on the street on the weekends and when i get into that power range i will be dropping the trans to change the clutch ever 15-20k miles. i also have an issue with the driveability of such a heavy clutch.

so my questions are these: what special bit did your lentech ATX have that made it strong enough to hold 735whp? the strongest trans i see on their site now is rated at 500whp. also what kind of life would one of those transmissions have at the 450whp range? would the lentech ATX last for a reasonable length of time between rebuilds as long as i dont regularly do high rev launches on 10 inch slicks. i know the ATX will be faster but what i am trying to figure out is whether or not it will be worth the money in the long run because im looking at $3000 for a lentech ATX and $1200 for a twin disk clutch that i will have to replace every 20k miles or so. so if the ATX lasts 50k miles or so i would call it a worth while investment.

All I can say is what mine did

I had over 100 dyno pulls tuning and testing things
I had over 75 1/4 mile passes and most of them in the mid 11`s

My Lentech ATX had
Stall Converter
Trans Brake
Manual valve body

I loved it I cannot say enough about the Services Lentech offered and did , the quality of there ATX , I didnt have to do anything but install , and some ATX fine tuning

It took 1 sec off my 1/4 mile time first pass and did nothing but get better after that

If I was o build another Focus to run 10 / 11 sec it would have a Lentech ATX hands down

I just looked before my first post. The toughest one they have now is rated at 500whp and costs $3000. Ill call them later today for more info.

And you can just build a tanny from your local shop using the parts for almost half that.

I would like to see you do that , prove they hold 500HP and I will buy them from you to sell

Fair enough? Other shops in the day tried and failed badly

There's a guy on fj who had a shop build his and I believe he is at least close to 500 whp and he dailies his car still to the best of my knowledge.

I'm really not trying to start an argument though I respect that you took your car to the limits. Not trying to argue with anyone here, just saying something someone else has done and I'm sure others have.

Chris and Len told me I could throw 800hp with the Terminator Strip setup I have. It's too bad I can't use a trans brake in my condition though.
