Developing a FAQ page for Drivetrain
I'd like to develop a FAQ page for drivetrain. Please help me create this page by asking the question and answering it if possible. Only relevent questions please....
Here's my first question to start off......
Q: What's the purpose of lighter flywheel?
A:??????
Thanks,

A :Flywheel
Less weight on the top of your crankshaft means less stress on the bearings and crankshaft itself. Additionally, a lighter flywheel will allow the engine to gain RPM quicker. Although peak horsepower will essentially remain the same, the engine equipped with the lighter flywheel will achieve its maximum RPM quicker.
Q, Our driveshaft will take 600HP. Is that rw or crank. If crank what does that equate to in rwhp in a 5AT.

Just like manual transmission cars, cars with automatic transmissions need a way to let the engine turn while the wheels and gears in the transmission come to a stop. Manual transmission cars use a clutch, which completely disconnects the engine from the transmission. Automatic transmission cars use a torque converter.
torque converter is a type of fluid coupling, which allows the engine to spin somewhat independently of the transmission. If the engine is turning slowly, such as when the car is idling at a stoplight, the amount of torque passed through the torque converter is very small, so keeping the car still requires only a light pressure on the brake pedal.
If you were to step on the gas pedal while the car is stopped, you would have to press harder on the brake to keep the car from moving. This is because when you step on the gas, the engine speeds up and pumps more fluid into the torque converter, causing more torque to be transmitted to the wheels.
It's real easy to get to too. Drop the tranny housing and it's right in front a small round donut. Ours have 3 clutches inside and yes I want a better after market one!

Does are car have a factory tranny cooler off the radiator like factory LS1's do ? (Usually upgraded anyway) but just curiuos if we have one at all. A5T BTW.
Does the B&M 19GVW or Summit Racing 16GVW plumbing for the 11x9x1 or whatever tranny cooler plumbing fit our cars for tranny and oil coolers or both?

I second all of those questions that 12secz asked and i'd like to add 2 myself.
1. Does are car have a factory tranny cooler off the radiator like factory LS1's do ?
2. Does the B&M 19GVW or Summit Racing 16GVW plumbing for the 11x9x1 or whatever tranny cooler plumbing fit our cars for tranny and oil coolers or both?
3. Our driveshaft will take 600HP (didnt know that, but its nice to know). Is that rw or crank. If crank what does that equate to in rwhp in a 5AT.
4. im thinking of ordering a TC with a higher stall. How hard is it to instal one urself?
5. how much hp can our rear differential handle before going boom, and does brake torquing hurt it? AT5 BTW.

Never heard that one bro.
Here is what I have heard at my track Sacramento Raceway.
"The NHRA requires all cars that run 13.99 or faster to have a drive shaft safety loop that meets general regulation number 2:4. "
Here is the complete specification word for word.
2.4 DRIVELINE
On any car in which the driver sits over or in back of the rearend center section, a suitable protective shield of .120-inch (3 mm) minimum thickness steel plate must be installed for those units with universal joints securely mounted to the rearend center section and the bellhousing adapter. Where possible, couplers are recommended in place of U-joints. For straight couplers, the minimum requirement is .063-inch (1.6 mm) aluminum which must contain an inspection cover for removal and inspection of the coupler, securely mounted to the rearend center section and the bellhousing adapter, or as noted in Class Requirements. In place of a crossmember, in the vicinity of the front universal joint, all cars in competition using open driveshafts, must have a retainer loop 360-degrees of enclosure, 1/4-inch (6.35 mm) minimum thickness and 2-inches (5.1 cm) wide, or 7/8-inch (22.2 mm) x .065-inch (1.65 mm) welded steel tubing, securely mounted and located within 6-inches (15.2 cm) of the front universal joint for support of the driveshaft in event of U-joint failure. Recommended the loop be round rather than oblong to minimize loading on loop. Open drivelines passing any part of the driver's body must be completely enclosed in 1/8-inch (3.2 mm) minimum thickness steel plate, securely mounted to the frame or frame structure.

What is the advantage of a dual disc clutch over a single disc clutch?
The downside of these setups is that becuase there are 2 rotating disks, when disengaged, they can rattle around a bit, so you have increased noise. It's not bad at all mind you, but it is there. These also tend to be grabbier clutches than stock in part due to the weight, and also due to the friction material used on the disks. The race only units from Tilton, AP and others etc. are downright nasty on the street, but they are ultralight and very compact. The larger units from Exedy, Cusco, etc (all of which are made by Exedy BTW) tne dot be more grabby than stock, but very forgiving compared to the race only units.

What does that sentence mean - specifically, "rearend center section"?
Would that mean the rear differential? If so, then it is not a concern on the Z since we sit in front of the diff, but I don't know for sure what they are talking about.
