So far so good. Very fast and repeated 3 passes within .02 in 96 degree heat and 56% humidity. At 68 lbs, this is one flyweight transmission.

Yeah, it's light!
Now you guys know why I have put up with all the hassles of doing the R&D on this thing.

It's been in and out so many times we have installed a zipper on it.

I do believe that it was worth it.

Wow, 68 pounds.

What does it cost per pound?

I think when I get my car finished I will have to start saving for one.

That is light. I hope it works flawlessly for you the rest of the year.

What kind of life expetency do you think you sacrifice with it being that light?

Well, we have been seeing 1-12 runs before frying the directs. The failures have been due to varried items. Everything from a fried trans brake solenoid, to broken Bellville springs, to stuck balls in the billet valve body. to galled billet pump gears. SO far we have 3 passes on it and they were perfect and consistant. Prior, we could not get more than 2 back to back runs without loosing .005 in ET. As I said, we have our fingers crossed, but it looks as though we have it under control now. We are looking for 100+ runs before any maintanace.

Alex, I must have missed the initial discussion about this tranny. I take it from the title "billet C-4" that all drums and every other part possible has been made from billet aluminum?
I see the weight savings mentioned but I also assume all the missing weight is from rotating parts where the most effect is gained?

Yes Mario, all of the drums and the sun shell are aluminum. Every steel part that can be lightened has been. Input and output shafts too! As has the case, extention housing and bell housing. Even the pan is aluminum.

What is the max hp/torque for this super lite C4? Think it would live behind a 429/460/514? And cost per pound guess?

Larry, we'll let you know in about 47 more runs.
If it can live in MM that long and pass wear and tear examination, then I suspect it can live over 100 runs behind anything. Cost will not be cheap, but speed never is.

Nope, speed nor lite is not cheap in racing nor would I expect it to be cheap but yes on dependable.

I got the first shipped ultraglide from JW years ago and at the time it wasn't cheap, but by todays prices, I got a bargin. I paid $2600 for convertor, ultrabell for bbf, the wheel and ultraglide.

JW's ultrabell for the C4/BBF is nice looking. Have one in the garage for my Tbolt clone. They reshaped the top of the bell so you have less clearance problems in most cars.

The JPT C-4 Ultralite is a success.
68 lbs less converter is the lightest racing trans available.
The trans withstood 60 passes since it's last incarnation and came apart perfect.
They are available now from JPT for $3300 complete with trans brake, sheet aluminum pan and any first gear ratio. About $500 less without the brake.

Alex,

How much reduction in ET do you think you got compared to your old tranny?

Thanks,
Marty
