Dyno - Power/AFR run

Kermit · Post by **Kermit** » Thu Nov 03, 2011 10:02 am

Wanting to do a power run to check AFR; is there a person/mob in sydney the club uses in particular and if so would you care to share?

If there is enough interest, perhaps a dyno day could be conducted that way there may be a discount involved.

The bloke who ran a mobile service I used last time on my previous bike appears to have disapeared.

I wouldn't use him again anyway. He didn't seem particularly knowledgeable and if you're going to put down your hard earned you may as well use someone who knows what they're doing.

Bikebiz Kawasaki at Granville is good.
Also doin bikes at chipping norton gets good reviews also.

Fair point, as its only a power run no damage should eventuate as its the equivalent to a 4th gear pull to red line.

If you know of anyone else, feel free to throw me a bone.

The real question is, which one has the most "optomistic dyno" so you can flash the chart around to your mates.

Haha, like a few gixxer k7 owner's I know claiming that there 1k bikes are putting out 220rwhp, with filter, zorst & pc.

I know dyno's are just a tuning tool and should be left at that; hence why I am only interested in AFR.

If a few extra torques on a rolling dyno correlate with my butt dyno; I'll be sure to brag about it

Well bikebiz used to run low, but have reconfigured it to run a bit closer to norm. Tex has one at minchinbury, but last I heard wasnt using it.
S and R pro at penrith one runs quite high apparently. But I wouldn't trust them with a push bike.

realistically there is a few things to know

a before and after reading

a time V HP graph again in b4 and after works well

its no good having 220hp if it takes 5 mins to get there

Deano's point was, people can sit around and look at each others printouts and say look my bike makes more than your's ect, pub talk, as he calls it.
as he says it not about peak H/P, but torque curves ect, how the power gets to the ground.
Ive had some long chats to him over the years, and i kno where he's coming from, there no bullshit with him, and thats why he will be getting my business, to do my headwork next winter, he has taken the time to explain everything to me in detail, no bullshit.

Power runs are only useful if they are back to back on the same Dyno preferably even the same day after making modifications to see what/ if they make any difference.
Any Dyno operator can fudge figures to make something look worse or better depending on what they are trying to achieve.
It can be as simple as changing a ambient temperature input.

Yep, things like air temp, air density ect, and yep got to be done on same dyno, otherwise it defects the purpose.
Example, deano did a guys GRXR1000 a while ago, custom mapped.
a little time later, guy went to another well known dyno man, dont kno why? guy came back to deano and complained that he didnt do a good job, as this other bloke found a extra 10HP!!
deano explained to this chap that this guys dyno reads about 10% higher than everyones elses, that he didnt just find a extra 10HP, i think he took that as a slight on his integrity.
