    My car is dynoed at 292hp at the wheels, lovely pedal feel, no clutch slip, if I want a snappy release then my next option would be a paddle clutch, Be careful not to go down the 'undriveable' rabbit hole with clutches, don't know about clutches sizes, my flywheel and clutch are matched to the size of the belhousing, can't go any bigger. Tavarish has his gallardo with a competition clutch and it's basically udriveable,

    txbuilder,

    What I was going to do was follow Jim Dinners build. What he did was use the disk from an 88 5000 Turbo and then the pressure plate from a Audi 90 Quattro 20V 2.3L. He was saying that PP clamp force was 1100 pounds but said that it was going to upped to 1500 pounds. I looking up the 91 PP, there are 2, one a SOHV and the other a DOHV. I am thinking the DOHV motor would be making more HP and torque calling for more clamping force. Am thinking that 300HP might just need the extra clamping. Will need to find out what I am going to need to have done to increase the clamping force. Not 100% sure I want the extra pedal force.

    I don't know about the diesel clutch but the turbo model has a larger disc and probably higher clamping force but I don't know that for sure.

    I do agree with you that it is the "smiles per mile". I try to do everything myself. The more money I save on the front end, the more money I have to spend on the back end. Right now I have lost access to doing my own machining so I am at a stand still right now.. I am in the process of looking for a lathe and a knee mill.

    I had a quote for $1800 for an adapter kit, clutch, pressure plate, flywheel , and adapter plate. I know I can do ti for a lot less. I am hoping to get the clutch disk and pressure plate for a couple of hundred dollars, steel for the flywheel for $100, and not sure what for piece of 6061 T6 aluminum 24"x24"x1 3/8"

    How well do you thing the Audi trans axle will hold up spinning that kind of mass? One thing I think I would have done was make the flywheel flange for the flex plate .001-.002 larger to make it a shrink fit along with the bolts. I am not planning to work the 016 hard, those days are long behind me.

    Would you happen to know where I can find information on the V12 crank flange bolt circle?

    Does the 01X take the same pressure plate as a 016? I am looking fro the bolt circle for the pressure plate.

    I have seen pictures that Diablo several times, in fact I have a copy of Complete Kit Car (2011) with a feature on it in the reading room right now. I have also seen it in a video on the DC Super Car display at Stoneleigh, really nice car, but what do you do with all of that power. Would really like to talk to him about his engine management system.

    Bob
    The 016 clutch is completely different than the other Audi clutches. You want to 5000 turbo clutch as it is bigger.

    No worries, I remember looking through there a few years ago when a friend of mine and I were talking about a frankensprit and I wanted to see what might be possible. Then I saw a nice audi v8 esprit project that was cheap easy and powerful. Gotta lot audi drivetrain

    Thanks, bratboy, didn't think about going over to the GT 40 forum. Figured I would start here as there were a number of members at one time that were building with this combination.

    Darren, Good old Casey going a mile a minute. He bought a complete adapter kit from A&E Kit Cars down in Texas. Eric was the one that quoted me the $1800 for the complete kit. The V12 is a stand alone engine as far as the crank goes. I do think the cyl. heads are similar or the same.

    Sorry I don't have any info on the BMW v12's. Most audi gearboxes have the same spline count, that's why I was able to purchase an audi rs4 clutch kit for the diesel box. Might be an idea to speak to a clutch centre and ask them to save an old worn clutch for you.
    I found my local Audi dealership parts department very helpful when it came to cross referencing parts, a good BMW dealership might be able to confirm whether the v12 and more common v8 crank bolt patterns are the same,
    here's a v12 supercar build that might help : https://www.youtube.com/watch?v=KNH8SqRwY9k

    I know there was a GT40 replica forum where quite a few people used Audi transaxles mated to Audi engines as well as many other types. They seem to have a good handle on how to do it this kind of work. I'd search them out

    The 01X gearbox is usually mated up with a dual mass flywheel and is really heavy. My set up is an a Audi 4.2 v8 ABZ engine, this mates directly to an 01X 6 speed audi gearbox, the flywheel just needed to accommodate the flexplate ring gear and tdc sensor ring, this meant everything was OEM where possible, the flywheel has some meat left on it, but also has a lot taken off it, the real weight is from the rs4 pressure plate.
    The idea was to have a reliable solution that was lighter than the standard setup and cost effective, no one offered a cnc machined flywheel with the integrated tdc sensor ring, Luckily I was able to produce one and at only 250 all in(including clutch kit), instead of 1650euros https://www.sachsperformance.com/en/...7-883089000038
    My build runs parallel to my home life and day to day life's expenses, the more econimical the build (without compromising the final result) the bigger the smile.
    I'm just a bioke in a shed building a kit car and having a bit of fun on the journey,
    The BMW v12 is a proven choice for Lambo replicas, the Audi gearboxes are also a good choice, the diesel boxes tend to be stronger due to the torque delivery of the engines, there's a guy who's got one of the best Diablos around, he uses a bmwv12 mated to 4 turbos, I had the pleasure of meeting and talking to the owner, and videoing it https://www.youtube.com/watch?v=u7LU7VviPlY
    cheers

    I was on your web site. That is a pretty interesting flywheel. It looks a lot heavier than it is. I find it interesting that there are 10 bolts holding the flywheel to the crank. You did a real nice job in the machining.

    Did you need to make an adapter to mate the engine and transmission? I am not real familiar with these foreign flywheels, they look rather thick.. If you look at a fly wheel for a Chevy or Ford, they are only about 3/4" thick. I have a clutch assembly for a 915 Porsche and think it is over 2" thick..

    Don,

    Did you ever check to see if you still had information on Jim Dinners flywheel build?
