Not another gearbox question?! A bit long, but quite detailed. Please read carefully to make sure you understand what I'm asking, before posting replies, as I am NOT asking about ratios or torque capacities.
Having had a good look round the paddock at Goodwood on Monday, I decided that there was a lot of fresh air under many of the engines which I would like to avoid on mine, so I am looking at getting the engine/ box as low as possible. However I do not think I want to go to the extravagance of dry sumping. On that basis I am looking for combinations which will allow a wet sump engine to be placed as low as possible. Would I be correct in thinking that the shallowest wet sump for a 351 W will be about 6.5 inches deep? (Armando)(Also use Accusump) So therefore the problem is how to get the block low enough that the bottom of the block is 6.5 inches above the bottom of the chassis, and horizontal if possible.
Fitting a Renault 21 or Audi 016 the normal way up with this configuration will result in the gearbox probably dragging along the ground and the driveshafts trying to drive through an angle of about 30 degrees, so not particularly helpful. alternatively the assembly could be angled using a pan with a sump in its rear to reduce the angle on the driveshafts, leading to the distibutor poking through the bulkhead, and air traps in the water system.
My current understanding of the main gearboxes is the following.
ZF. The output shafts are ABOVE the input shaft (best combination, but most expensive)
Audi 016 and 01E, and Renault 21 and 25. The output shafts are BELOW the input shaft. This leads to the problem detailed above.
Porsche can be fitted either way up, but again much more expensive than Audi or Renault.
My question then is what is the best way to fit the engine as low as possible whilst still using Audi or Renault? Can they be inverted? If so who has actually done it? What is the best/ lowest compromise in terms of angle of assembly/ angle of driveshafts.
