250awkw = Roughly How Many Fwkw?

Mate sounds like a very high reading dyno as the norm we have seen is around 155 awklw and modded WITH injectors about 250-265

You may be right, as I doubt the bung removal would push it from 155 to 194 in stock form.

I guess a track time will tell all, so I'll post up what it does down the quarter. That'll give us something firm to compare against.

Either way, I'm stoked with the results, as it drives beautifully.

I would say 315 fwkw. I dont think the percentage argument stacks up. I think you lose X amount of kw through your drivetrain regardless of your power output.

Years ago they always said 30%-35% drivetrain loss but that is on stock power. Now all of a sudden its about 21%.

But note this....

165kw Expensive Daewoo V8 made 108rwkw stock so 35% drivetrain loss (lost 57kw)

245kw XR6T made 190rwkw so 21% drivetrain loss (lost 55kw)

BOSS 290 mades 230rwkw (lost 60kw)

Expensive Daewoo 307 makes 245rwkw (lost 62kw)

Three cars lost around 55-65kw.

Im sure its no exact science but I say it would be a number regardless of your power rather than a percentage which would diminish as power rises. My number comes from adding 65kw to your rwkw.

I have a magazine (MOTOR) where it was quoted that on CV's dyno a stock XR6T (240fwkw) did 182rwkw.

hulk, what if the car only makes 70KW on flywheel? does that mean it will only have 10 KW on the wheels?

I think it's percentage rather then an actual number.

Generally, you multiply the rwkw figure by 1.34 (which is actually horsepower conversion), which roughly gives you flywheel kilo's.

This is very general, old wives way. Chucking 4WD into it may upset it a little.

So you reckon a T with 55kw at the flywheel wouldn't be capable of moving at all?

I'm going to tear out my motor so we can settle this once and for all.
