a spool or welded diff with stagger is the simplest and cheapest way to go, and works quite well, except for the tire wear and slight loss of speed from friction when on the strait sections of track. Also stagger is set up for a particular radius of turn. A lot of tracks have turns of various...
If you ever need to go lower with the rear RC than possible with the Panhard or Watts can achieve there is also the Mumford Link:
The RC is the imaginary point where the two long links would intersect.
Yeah, I guess if it is a sealed crankcase, the pressure when the piston is down will give a slight boost pushing it back up, but I haven't really seen any sealed crankcases. Most engines, even small single cylinder ones have some kind of crankcase ventilation. Sealed crankcases tend to blow...
Why don't you start pulling those headers off the m60 before you say it's a piece of cake. There's barely room for the stock headers, which are double wall by the way. It is double wall to keep from melting everything in the area since it's in there so tight.
Even if you are capable of doing...
I think buying a 530 is about the dumbest thing you can do if performance is a consideration. That has to be the heaviest 3.0 liter engine I have ever seen, why wouldn't you get a slightly newer E39 4.4 or 4.6L 540 that has much better suspension, and way more power than you'll ever make by...
I have looked at the Torsen designs, and the single pinion T-3 is what I am looking for. It provides up to 65% torque bias. It is used in a wide range of AWD applications. I will contact them about what spline outputs are available, and the case drive mounting. It should be simple enough to...
The closer to the valve the better I suppose, and I don't think shapes will matter much, but I don't think there will be enough energy there unless the exhaust system is heavily restricted(more so than would be reasonable to do).
I think you could scavenge more pressure/energy from the...
I think the ground circuit of the ignition coil could be separated from the vehicle's chassis ground(which is what is connected to the engine block). It would still need to have a spark path that is not longer than an adjacent path that might go through a part of the combustion chamber, or you...
Oh yeah, with the planetary I described, the left wheel would spin backwards when the right side is held, and the right side would turn at reduced speed if you held the left side.
Even if it is banned in classes that only allow open or welded or spool type diffs, there are plenty of classes...
I know a lot of tracks and sanctioning bodies allow either open or welded open differentials, as well as the detroit. A few even allow the helical type, and those are quite popular where allowed, often referred to as "torque sensing or biasing diffs". they are often called a "Torsen-Gleason"...
I know that some AWD vehicles used the gear ratio of a planetary or other transfer gear combined with a gear type torque biasing diff that would allow a natural mechanical advantage to apply more of the torque to the front or rear axle.
Why not apply this to a rear diff for circle track...
I guess one important factor for choosing spindles that wasn't even discussed yet is steering arm placement. It will determine where the rack and pinion has to go.
Those look very nice, and very expensive. If you were to pay somebody to make those from what appears to be stainless steel, I would expect to pay upwards of $2000 for the pair, but then that's still less than the Porsche stock uprights from the GT3 RS which is what I need to correct the roll...
Pretty much all modern cars have some positive offset to the wheels. Usually, it seems, the wider the wheel, the higher the positive offset. The wheel and tire sizes you mentioned are very common on Porsche race cars. The wheels for these cars have about 50mm or 2" of offset, which for the...
Might the variance in specs be due to static camber changes causing SAI to be different from the Kingpin angle, which would be the same as SAI only at 0 camber?
As to scrub radius affecting feel: I have found larger scrub radius having increased kickback and negative impact on feel...
