Dyno figures

[Frunknmont]

What kind of power figures could you expect to see from a stock R33 GTST when dynoed?

[geno8r]

I have no idea really but I'll throw a guess at 130 rwkw?

[Frunknmont]

That's what I was thinking too. Can't remember where I heard it but I heard the average loss through the drivetrain was about 50kw or so. But anyway the reason I am askin is because I had mine dynoed yesterday and I got 162kw

[geno8r]

Hmmm totally stock hey... doesnt sound right.... Still stock exhuast & no Pod filter? Care to post up dyno sheet?

[rukus]

that's a bit much me thinks

is it a series2? my s1 r33 made 153rwkw fully stock.

Gezzz even 153rwkw sounds a bit high... Stock they're only meant to be around 176 kw @ the fly...

Yep stock exhaust and airbox the its only had suspention mods so far. Even I was a bit hmmmm about it, I was expecting it to be alot lower. Have to wait till I get home to post up the sheet but.

i thought a gtst is 187 @ the flywheel

thats why I said 'around' I couldnt remember exactly

[rukus]

ye well im pretty sure a standard 33 gtst is about 150rwkw

[geno8r]

Only a 37kw loss in driveline then. Sounds quite small... SK saids a 60 kw loss in driveline is pretty average, I've heard this from other sources as well 'not just on skylines, could be clubsports or whatever'.

Where is the dyno? I'll go for a power run on that anytime.

Its too high.

Oooooh, here's a go :matrix:

So if I have GTR that has a standard engine and makes 250 kw, that means 150 4wkw. ie; the drivetrain and the dyno loses are 100 kw.

I take the engine out and swap it for an engine making 750 kw, that means 450 4wkw ie; the drivetrain and the dyno losses are 300 kw.

First question, how can the same gearbox, diff, tailshafts, drive shafts, wheel bearings, dyno rollers etc suddenly soak up another 200 kw?

Second question, according to Newton's law, energy can neither be gained nor lost, it is simply converted into other forms of energy. So where does the extra 200 kw go? Heat? That would be enough to melt the gearbox case on the dyno.

PS; Don't give me the E=MC2 argument, there are no atomic reactions going on in my Skyline.
