Ever had your car/bike on a dyno?

[Jrod]

No not a rolling road but an actual dyno....

Well I have!

197bhp and 158lbft from a 1.9 engine. No dodgy conversions from wheel power to flywheel power either!

Nice numbers, but I can walk faster than that.

Yes, had my GPZ500S dynoed a few years ago, from a claimed 60bhp from Kawasaki it had 59bhp at the crank.

Although after the dyno, the bike never ran properly afterwards and ended up having to have a replacement engine. At the time I seem to remember I blamed it on the trackday I did on it, but I am now convinced it was the dyno. :-/

He's asking about a dyno, not a rolling road. I had my VFR on a rolling road to check it was all okay before i started to fettle it.

[P.addy]

Im stupid and unaware of the difference, but engine makes ~400hp, not sure on the torque... but it cant be all bad.

Also near 200 from a 1.9... cutting it fine arent we sir? my 1.8T was making 161... and im pretty sure thats before the engine starts to suffer on that car, obviously if its a jap car.. i fully understand

My bike came with dyno traces from the previous owner trying the stock exhaust against a different end can when it was about a year ld. Academic now as it had an entirely different exhaust on it when I got it.

Catcams and throttle bodies with an 8 injector setup.

Next stage would be pistons with deep valve cutouts so you can have more lift and also some work to the cylinder head.

Cool, just had a quick look at some of those pics, reminded me of the days I used to rebuild 5 turbo engines. Looking through the engine block and seeing the garage floor brought back memories!

I'll have a proper read through later.

Just read the build thread, looks like a very good, clean build.
