some ones been playing a little to much gran turismo:skid
WAT.
wut :skid
Hate to say this guys, but skid is on the right track. A lightweight driveshaft will produce gains on the dyno AND on the street/strip.
what a 2-3hp/tq increase on this car? The difference is 110% negligible on this application
rofl:rofl
The only thing I could fathom he’s thinking about is overcoming inertia more efficiently through less rotating mass…its easier to get a lighter driveshaft moving from rest. But I have no facts to back this up.
^That is exactly what i mean. the rest of you are :skid ed for somehow getting grip out of that.
Like I said… completely unnoticeable difference on this car. Maybe rear end gears or a different driver would make a real difference. Switch to an aluminum driveshaft… what are you half a ritard?
on THIS car. little shit like D/S, trans tune, gears, tire wear even tire pressure can add up to make a noticeable difference
it’s not me that’s the 1/2 tard, it’s you that’s the full fledged 'tard.
OK specialkid 1/4 mile expert. Thank you for you input from vast experience and knowledge of vehicles and motorsport.
Pipe down fuckers!
Car is slow.
Im fat.
My balls stay cool.

Less rotating mass equals less tourqe. Been researching this for weeks with flywheel weights for my wrangler to give it more low end. Tourqe is what’s gonna get you off the line faster. Just sayin.

Plausible, but at what point does it stop. Heavier wheels, to move this discussion down the driveline, wouldn’t apply more torque to the ground once the limit of adhesion has been reached, right?
Where underboosted is going with flywheel weight is applied torque to the drivetrain and then the wheels.
IE 4.0 spinning a 30 vs 21 lb wheel will have more torque to apply to the driveline when you let the clutch out, due to the additional energy created by spinning the heavier mass. The other side of the coin is the engine has to produce more energy to spin the heavier wheel. Optimal flywheel weight really depends on vehicle intended use and complete drivetrain setup.
Also skid the caddy should have an aluminum DS from GM. They use aluminum on all the DS and torque tubes for reduced rotating mass. However it’s done to improve highway fuel economy 0.01 or w.e. MPG. In the real world aluminum vs. steel no real difference on quarter mile performance in a 13 sec 6k pound car. It’s like the difference of a spare tire in the trunk or not.
see that’s the answer i was after. ~10lbs off of 3 tons isnt gonna make a difference
^ Are you serious? You literally said on the last page that saving weight by getting an aluminum driveshaft would improve the car’s 60’ time. Now you’re saying the saved weight isn’t going to make a difference? Man you are retarded.
yeah cause clearly aluminum is a better choice.
put it this way…
my car from the factory had a 3.5" aluminum driveshaft. It broke.
I now have a 3" chromoly PST driveshaft with a forged yoke. Guess what? my car is the same with it.
your theory is butt fucked. Your talking a very minimal weight difference. If you wanna talk about rotating mass, looking at wheels/ tires or even flywheel’s. Not the driveshafts.
