  • V drive? what exactly is it?

    I've spent about 2-3 days looking on here and google, and cant much info on it.

    I saw that the authentic lambos use a transmisiont that goes forward, then back to the rear axle.

    Ive heard talk about the "V drive" but no pics or any indepth talk of it.

    Also heard talk about the cyclone 1:1 transfer case. Is that the same thing?

    Transaxles seem so to far out, I couldnt fathom spending the money if I had it.

    If yr talking about the same thing, I saw one of these on an old episode of Monster Garage- they took an ambulance and made it a wheelie car. To do so, weight had to move back as far as possible. Don't remember why they needed v-drive or what it looked like exactly, but basically it was 2 short driveshafts, one pointed down and forward, the other pointed up and to the rear, sort of like a < or >. Used a standard RWD transmission. Either the differential yoke pointed to the rear, or the engine faced the rear of the car. Either way, the driveshaft came out the trans, angled down, into the V Drive housing, then another driveshaft went back out of that in the other direction and down, then went in the differential. Tough to explain, but simple concept - doubt it would accomplish what you're trying to do though, which seems to be 4 wheel drive?

      Naw I wouldnt want 4 wheel drive, just trying to avoid a transaxle. Rather use a T56 as a tranny. Maybe in a few years the 6l80E price will dropp (some company has it rated for 800lbft and paddle shifts, I cant remeber who but 6.9k )

        I remember seeing a Diablo build that used a 1to1 V drive. He mounted the engine
        (ls1) in the rear with a normal style manual trans pointed forward. IIRC he used the V to put the power back to the rear of the car and used a standard rear IRS diff but off set to clear the engine.
        Looked like a rear slick set up and it did work ,he finished the car and drove it.

          go over to www.kitcentral.com and research kevkev6.0 nice build just like you are talking about. it has been done for years in the 2wd buggy and 2wd sand drags. The buggy folks use a divorsed transfercase instead of v-drive because of the v-drive whine

            Seems like most lambo builders use a Porsche transaxle - I thought the going rate for them was $2500, but I could be wrong. There's a member on here named switta - built a sweet Diablo roadster. I thought he used the Porsche, but I'm not sure.
            If it were me, I'd prefer a transaxle over a trans, driveshaft, differential, axles, etc. Fewer parts to break, and I'd guess more power would make it to the wheels.

            EDIT: switta used an Audi trans

              just a note on prev , Ive been in the Lambo seen a while now, most uk lambo replicas used a Renault UN1 box but getting rare now, most new builds now using 5 or 6 speed Audi box, havent even seen a porsche box in one

                Yeah I was looking at audi trannies and porche trannies, but the cost of getting a it too work seems kinda high. I know if I get one im going to hard on it.

                Im going too look into kevkev6.0 build. Is that the same guy with the offset motor? If so thats where this idea realy came from.

                T56s > Transaxle cost wise.

                Forget top speed, id be scared to take a car I built over 170mph anyway an its illegal on the highway

                I just wana run in the mid 10s in 1/4.

                EDIT

                In all actuallity, I dont know too much about transaxles thats why I wanted to stay away from them.

                All the good new transaxles cost 14K that can handle a power level I wanted.

                    Try car-part.com to find a transaxle from junkyard.

                    Basically, all you need is an adapter plate to mate the engine to your transmission. I imagine someone makes them for the more common applications - Audi to Chevy V8 bolt pattern, maybe?
                    Other than that it's just making mounts and axles.

                      Re: V drive? what exactly is it?

                      The issue is how much horsepower, torque and traction are you going to have? If you keep things reasonable, say under 300hp then you can reliably use an Audi or Porsche 901 style. Over that they will not be reliable and with the audi I would still use the reinforement plate that you can get from Chassisworks and others. The Audi is questionable above 250lb/ft of torque. If you are building 500hp then a transaxle quickly becomes an expensive proposition with the least cost probably right now being an RBT 6speed built for the Ford GT. They are commonly available over the last few months for around $7500. The option of using a normal RWD trans back to a divorced transfercase or v-drive starts to become more attractive. And yes kevkev offset his motor slightly to make room for the driveshaft, there may not be a way around it. Because not only needing to make room for the driveshaft but to get the rear differential a little more centered so it is not so offset to one side.

                        Offset rear wouldnt bother me too much.

                        If I build a motor the min in power I want is 400hp. Prolly even more tourqe the Caddi 500 motors have been catching my eye lately. 500hp 600lbft when built properly.

                        But everythings up in the air.

                        I know with me driving and a 100hp motor infront a transaxle. (I love burnouts, an gear chirping)


                        Have many people that build kits, use the configuration i want to run?

                        If so have any of them ran solid rears as oposed to IRS?

                          Hi,
                          Seems to me that you are looking for a reverse direction transfer box with bolt on flange fittings , something like this -

                          Hope that gives you some usefull ideas.

                            Check this out.. The guy that built my Aldino has built a new Fiero and he has a modified LS7 that put down 621hp on the engine dyno.. He has the car on the road now and he will make over 600hp to the wheels once the engine is ready to be dialed in.. He plans on running 9's.. 8)

                            He is using your only logical choice of trannys.. ;D

                            Check his build out here > http://www.fiero.nl/forum/Forum3/HTML/000083.html

                              Oh, I rember a V-drive system back in the early 90's they used in a Countach and it was neat with the way the engine was laid out.. It basicly had a ford 9" diff right off the end of the tranny and pulleys on each side of the differential that run belts to pulleys on the inner hub of each rear wheel.. The whole setup was self contained and mounted within a boxed subframe..

                              I rember they stated it was a very very noisy system and not very efficient..
