Dyno Day with the #27 Bike

[skidlids]

Now minus the Nemesis ECU and in its place a reprogrammed standard ECU with the IMMO function turned off

Result measured at the rear wheel on the Dave Wood Racing (DWR) Fuchs Dyno, with Junior as the Dyno operator
64.2 bhp and 42 ft lbs of torque

Awesome. Phil will be delighted

be good to see some racing this year!

So why are those two torque graphs reading approx 36 & 37 & not a 42 in sight??

Also why is there no RPM on the scale the speed means zilch we use a tacho on track. :o

[bradders]

I wondered about the rev being missing, speed instead isnt something I've seen, but sure Kev will have loads of print outs

Didnt notice the torq but very low if its sub 40

Read it again............

I give up I can't see it. Also I'd like to see the rpm scale so that torque and power can be seen to coincide at 5252 RPM.

Kev.

There's something amiss with the comparisons between the runs? I suspect that you weren't running the same gearing/gear?

Scale on the right. 5.8 Kgm is around 41 ft.lb.

Just spotted it, 5.8 calculates to 41.95 ft.lb. Who the hell uses Kg/m for torque??

[skidlids]

Both runs done on the same gearing, the bike never left the dyno between the first run and the last, maybe one was in 5th and the other in 6th

I have another dyno sheet with just the final outcome and on that one the torque scale on the right is ft lbs and it has the rpm across the bottom scale

[SeeleyG50]

Ok. Just that you can't be making more power with less torque between 70 & 80 mph, therefore something was amiss :rolleyes:

Other than that, it looks good. Although I'd look at that ragged top end. Plug grade?

No A/F ratio readings Kev?

Not on the graphs Pete, but the mapping is per cylinder with a Lambda probe inserted into both the front and rear header pipes
