Auto Conversion looks to be the final step once I finish up my car this time around. I am hesitant on going to the 4L80 because of the added weight, parasitic loss, and shear amount of customizing and massaging of the car to make it work.

My seemingly very short list of options are:
PG Conversion
Or a Level X 4L65

The car is mostly street and highway, so I am somewhat hesitant about going glide, although it will make the car an animal from a dig. Car will be making between 950-1100 on my manual trans for now...
So I am curious as to who has a Level X:
How long hve you had it?
Street? Strip? Both? How many passes from a dead hook? How is it holding up?
What power level are you at?
Would you have done differently?

Wonder if RPM will come up with a level 12 soon haha! Or maybe they will do some extra beefing up of the X for me in particular. It's an expensive piece as is, around 6k no core.

Anyone?

Not a lot of people on the forum running the X yet, hell they just came out with the X last year. Lots of people running the level 7 though. The X is basically just a 7 with a Sonnax drum, bolt on billet end cap and I believe a thicker or extra clutch plate in the drum.

Lots of people have the 7 with good success and a few had some bad luck.. However I don't know of anyone on CF with 1000rwhp thru a 60e besides Arun, who did make 1k.

Most of the cars with 4l60s are in the 800-900rwhp (locked) range, and they seem to hold up ok there.

3-4 clutches are the first thing to go.

I'll be pushing the limit of a 60e as well as I won't be doing an 80e conversion on my car.

My buddy c5mtl is running 1000 hp through one. I will ask him to chime in here if he doesn't see the thread.

under_psi

Get him in here!

realcanuk

Haha... PM him or I will text him later when I have time.

under_psi

I sent him a PM.

under_psi

Good convo between me and him earlier. His is holding up to 1050rwhp. Car has already been in the 8s with it.

There has to be more than one person with this transmission though....

realcanuk

Yup. I've seen it run 8's. A beast. I will probably be doing a swap myself eventually. Don't think my 6L80 will like a YSI for too long.

under_psi

Let me know when you plan on doing that. Maybe they will give us a deal on 2!!

Your friend told me if he could do it over he would have gotten an extra gear set to soften up the strain on he launch. No cheap but worth it. He also didn't care for a trans brake much. He doesn't have one and is cutting Nasty 60' and running 8s.

realcanuk

Not sure how you soften the launch and still run 8's. Lol

I wouldn't get a trans brake either. I'm not that serious about racing.

I don't know when. I will see how mine does this summer. Then figure out what to do.

under_psi

Soften it as in making it easier on the transmission, not you haha.

I don't know either when I will do it. Maybe we can do a group buy lol

If I recall doesn't "itstock" the white 8 second AMS car have that trans in it? From what I see that car runs strong! Thought it made like 9 something but on a mustang dyno! after checking it out... 930 wheel on a stang dyno is about 1k wheel on a dyno jet, I'd contact him and see how his VII is holding up!

under_psi

This is a level 7, and yes the car moves out!

This is what I want!

1MEANGS

Yeah if the 7 is holding 930 wheel
On a stang dyno, which should be around 1k on a dynojet... I think you should be pretty solid with a X

c5mtl

That car comes out in the 1.20's with no brake....very explosive off the line...if I could come out 1.20... Wow mid 8 here I come

ATLS2

I got the level X last march as a late Christmas present. If any changes in technology or better parts come out, it will go in the level X and still be called the level X. I also did the stage 4 diff and brace at the same time. They did a stage 1 A&A, dewatts radiator, and dual fan while working on the car. I was building up the car for when I remove the restrictor and add a 100 shot.

Jeffro_510

Im in for real world results. If it can hold the power, i want one for sure. Much better option than shelling out $18000

under_psi

So what are you currently making?

blown81bu

I will be testing my level x rpm in the fall...
Stay off dynos and I think we got a bullet proof piece here
