.Not bad for an old.smoker eh.
.

yea but the bike wasent to bad tho

You were taking no prisoners out there. I was doing 58s laps and you came past me like i was standing still!!

First and second for me with a measly 48bhp!

Don't forget, it was an SAE not a DIN dyno.

that was the DIN figure, I've really got to have words with myself because mine made 60!

I think the guy was converting them..mine was 46 then he said 'hold on you aremeasuring ....(missed what he said but may have been din) so 49'

hot engine, 18 laps of being hammered and no oil cololer...happy with that

Chris this means nothing to me? Explain please.

There are two types of Dynometer, I am not up on how they work, but to say that the SAE dyno reads Lower than a DIN Dyno.


Horsepower is a measurement of the engine's ability to perform work. One SAE
horse is the ability to lift 33,000 lbs one foot in one minute. One DIN
horse is the ability to lift 450000 kg one cm in one minute. For the same
power the SAE measurement is thus 98.629% of the metric DIN measurement.

As Bradders said, his reading was 46bhp in SAE and when converted to DIN bhp it was 49bhp, and as maths is not my best subject i will leave it to you to work out the DIN bhp from your 53 & 55bhp, if that is they where not converted to DIN.

Well I would ignore that figure as its not the same power measurement
Based on the figure of 98.629% you would need a SAE of 48.33 bhp to arrive at a DIN figure of 49 bhp

I will hopefully be provided with all the figures so I can see what if any ammendments need to be made to our rule book

From what i can work out the Parkitt Dyno reads in NET SAE J1349 spec which then needs converting to GROSS DIN 6270 spec
This conversion seems to be roughly 7.5% so multiply the figure the Dyno reads in by 1.075
My bike read around 55.6 BHP (SAE) add 7.5% to this and you get 59.77 bhp (DIN) the DIN Dyno I had it on last Tuesday measured it as 61.1bhp

My Class B Monster measured 45.52 SAE which converts to 48.93 DIN

I think you should post up all the results Kev... Should make interesting reading!

Like I said, math's is not my strong point
