If you have something generating energy and you have a percentage heat loss due to certain factors, with all else remaining the same doubling energy output will result in EXACTLY doubling heat output. Its a law of physics and has been proven innumerable times.So let's say I have a gearbox that transforms 20 kw of power (torque X rpm), or kinetic energy if you like, into heat. Why would it suddenly transform 40 kw if I double the power output of the engine?
1450bhp. Your Legnum won't get anywhere near these figures,
The percentage loss methods just doesn't work for me. Especially when you start tripling or quadrupling the power output, the heat would melt the aluminium gearbox case on the dyno.
Some examples;
I know that an R32 RB20DET is rated at 215 bhp by Nissan
When I put one on our usual dyno they make 140 rwhp
That's a loss of 75 hp through the drivetrain, tyres rollers etc
I know that an R33 RB25DET is rated at 250 bhp by Nissan
When I put one on our usual dyno they make 170 rwhp
That's a loss of 80 hp through the drive train, tyres, rollers etc
The above is based on the real world results for over 20 Skylines on our usual Dyno Dynamics roller dyno. Dynos are different and different operators get different results. This is our results, but I don't believe that you can simply transfer them to someone else’s dyno. BTW hub dynos show less power loss, due to their lack of tyres, friction and rollers.
