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

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.

      Is it alright to top up with just another green coolant?
