• DCT Build Part VIII - Putting it back together

      As of right now, the transmission is completed and the cooling system is in the process of being completed. Where we left off was the car being taken to SSP for the build of the cooling system. To make this all make sense we will not skip ahead, instead showing you each step. Here SSP is getting ready to put it together with the new clutch discs. They laid out all the parts and used 3d scanning equipment to record them to aid in the production of the parts. Everything was laid out to make sure the parts were clean and accounted for. Additionally, they were working on prototype viton seals for the transmission. The next update will have details on the cooling system.

        T trim Kinda big. I'm all for the ysi tho!! You and tightie Need to get these cars out there. E92 growing on me. Doing $#@! right takes time tho. I agree gintani are the only one doing built motors.

        Wish the marketed alot better!! I mean alot.

        You aren't the only one, I'm tired of some of the negative press that would be *very* easy to correct with some proper documentation.

        T-trim was big for the S54, but even a YSI could be done on the S54 so I think it's the right choice for a built motor S65. Trust me man, I'll get it out there ASAP. I want nothing more than to take this car to the strip, do comparisons, 60-130's, hell, I may even take it on the ring.

        I don't know if it is quite this simple, but it sounds like a Procharger setup might the answer to everyone's belt slipping problems:

        From a plumbing standpoint a ProCharger F1-R is equivelant. 4" inlet, 3" outlet and a 9.75" volute. The F1-R can flow 400 cfm more air so it has some 250+ hp more potential. It is also self contained. The YSi uses a 3.45:1 transmission ratio, the F1-R a 5.40:1. What this means is that for any given airflow level the ProCharger will use a larger driven blower pulley. This increases area and belt wrap helping you obtain your desired boost without slip. As an example a common crank pulley diameter for an LT1 is 7". Say you want to drive the supercharger to 50,000 rpm @ 6600 engine rpm.

        YSi blower pulley diameter - 3.18"

        F1R blower pulley diameter -5.00"

        57% larger diameter for the F1-R at the same speed. This does wonders for belt traction and it is precisely why it was developed.

        In the previous weeks we brought you the details on the DCT oil pan upgrade and the pictures of the machining process. We are happy to say the final design has been completed and here are the pictures of the finished product. Once again, this will allow 2 additional liters of fluid as well as the capability to connect to an external cooling source as you can see from the openings. Pricing details for the complete DCT cooling kit as well as components will be coming next, stay tuned.

        Yes, getting a custom transmission built that nobody has ever done takes a wile. I'm patient, not a big deal.

        The engine has to be installed, then a supercharger chosen, then the tuning. I may also stroke the motor which would add time, we will see.

        Yes I would be ready to murder many kittens, and puppies at that point.

        I won't murder any animals over build time on complex technical issues. It is all coming together and there will be a lot of fun had when it is done.

        I will also murder humans/aliens for these reasons.

        Wait I thought you said the motor was already built? So how would you then stroke it?

        Yep, the motor is built currently at stock displacement with sleeves (slightly more bore).

        If I want to stroke it, they offered me a good deal to do so but that would involve a rebuild, yes. New crank and new rods.

        I'm tempted to be honest.
