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

    • People still have Skylines? I thought they're non-existent now. 
    • Harness update time have had great fun and learnt so much already so far with this project. I started off making both the ignition and injector sub harnesses in the hope any mistakes i made here aren't as hard to undo and learn from as the main harness.  A cool comparison of the old harness using presumably TXL wire and the new which is using Tezel. Also opted to use DTM plugs to keep the whole setup as neat and tidy as possible and tucked the wiring under the coil bracket to try and keep it all from sticking out too much. Although the injector harness, I'm not overly happy with as I'm still using the rubber boots that are supplied with the type of plugs it just looks ugly and sticks out like a sore thumb with the white identifiers so a slight redesign may be done.   Then it was main harness time and most importantly trying to route it nice and away from the heat it will use the OEM heater hose routing which is no longer present to keep the harness up high and secure. it's amazing how much smaller this harness is able to be compared to the old one. plugged everything into the emtron and with the help of the tuner again attempted to start it up and instantly fired up and running smoothly on all 6 which was a big shock to myself. So still some routing and adjusting to be done for the final fit up and installing a knock sensor harness plug which is in the post all has gone surprisingly well.     The old harness for shits and giggles.
    • They do that at random every now and then, with almost no detectable cause. Mine has done it a couple of times (over 25 years!!). Never worked out why.
    • I don't post on here and have been lurking for some time now. Many of the topics have helped me out more times than i can count. I was racing yesterday (11/9) and blew a front right CV shaft. I have spares so I popped a new one in. A thread i read previously said to check the engine mounts if you blow a front CV. Upon inspection, the front right mount was completely separated from the upper plate. This discovery saved me time and money, because i would have blown another CV if i went back out. Just wanted to thank you guys and wish everyone luck with with their builds. (Now if we could only come up with a solution for my power steering belt flying off after hitting the rev limiter, lol)
    • Either way he still need those style of spacer to go into the manifold because the photo he currently has is not going to work
