i always thought it was:

FWD is around 10-15%.

RWD is around 15-25%.

AWD/4WD is around 20-30%.

but this also all depends on if its an auto or a manual.

Well 206kw R34s godown to about 150rwkw. Take off about 60kw

300kw HSVs dyno at about 225rwkw. In this case 75kw

going off these figues they are both around 25%

Where do people keep getting these ideas about drive train losses being a percent?

Example:

my GTT is making 1000kw at the fly wheel and you say i'm losing 30%. That gives me 700kw at the wheels.

300kw loss through the drive train. That would mean your 335kw GTT motor wouldn't be able to turn the back wheels on my GTT because all your power is being consumed by my drive train. But the drive train is identical.

Your GTT lost 85kw

My GTT lost 300kw

how do you explain that??

Drive train loses are NOT calculated by pertanges.

If the HSV lost 75kw and it's a manual and your GTT is a manual, same size wheels, blah blah blah, you will lose about 75kw. Or better still if someone is saying that a 206kw GTT mays 150kw at the wheels (56kw loss), guess what, your 335kw will lose about 56kw.

Agree with Drivetrain loses are NOT calculated by percentages.

In this case probably a little more I would say 60-65kw loss, partly due to increased heat from the extra power.

The issue of drivetrain loss has been discussed thoroughly before in this thread:http://www.skylinesaustralia.com/forums/25...Kw-t169392.html

      Anti Squat Kit

      By robbo_rb180 · Posted

      What are you doing with the car? street car or race car? People get hung up on the squat of the s/r chassis rears. There is positives to the squat if a car is setup and driven correctly for it (correct ride height, spring rate, alignment, damper valving). Generally just lengthen the rear traction arm by 5-10mm and that will help the squat and bump steer too. You are also correct with the roll centre too. This too also needs to be adjustable if you start messing with suspension geometry.   Having done quiet a bit of testing on race cars this year in regards to rear squat, I've seen some big positives from it in regards to drive off corners and traction.

      I find I am using the MX5 for everything except long overnight cruises with Jackie, or, if picking up the kids to go somewhere, the SS has so much more room inside, and is much more comfortable if your going to be doing Hwy driving for 6-8 hours And the MX5 isn't bad in stop go traffic for a manual transmission car, whilst the clutch kit has been upgraded from stock, it is still light, and also not having a stupidly light flywheel in it helps as well, I've spent alot of time sitting on the M5, M4 and M7 stuck in traffic when plodding around the Greater Sydney Region in it Another benefit is MX5's are not really a car that gets stolen, you can pretty much park it anywhere, and it will still be there when you return

      I can totally get why you like it for that sort of commute. I was thinking BoganDore because it's such a lazy drive, for things like stop start traffic.   I used to do over an hour in stop start shit from one side of Bris to the next, twice a day. My choice of car was larger displacement, with an auto. Basically for torque in low rpm/very low speed, and no clutch pedal. But loved a fun manual for the weekends, which the partner has (plus had the LandCruiser too for other fun drives). I now have an EV as a work car, and I tell ya what, ultimate daily driver, especially if youre out of energy, like I often am after work. I don't even need to touch the brake pedal   That said, I'm presently rebuilding the Liberty GTB to get it setup for weekend drives and track abuse! So small high revving turbo engine with 6 speed cog swapper!   But for your style of commute, I'd probably take the MX5 too!   For those choices, I'm ignoring fuel economy. Because I know how atrocious V8 daily life is for fuel from when I used to daily a manual SS, ha ha. Hence why I know I love the daily rumble of a V8

      People just don't understand how good MX5's actually are and how fun they are to drive, park, manuever. You feel like you have got some fun cheat code, while everyone else is sitting in their luxobargeSUV like normies who missed the point of living. It really is that noticable. As long as you/your stuff fit, and you're comfortable (they are), a MX5 is the best car on earth to daily around.
