Faast Ed, I understand what you're saying. But I'm not suggesting dyno passes at lower RPMs or lower gears, I'm suggesting dyno passes at different throttle openings. And, as Jamie just proved in a previous dyno sheet, a low curve on the dyno sheet at WOT does not mean a low curve at part throttle, when he published a SE255/TW555 comparison in which the SE255 had significantly more torque between 2,000-3,000 at WOT but the TW555 had significantly more torque in the same range at 1/4 throttle. I would think that multiple passes at different throttle openings would give us a better picture of how this particular component would work in our own bike - in that case, we were comparing different cams.
As far as real world conditions, I won't be racing anybody at all, and I would gamble that most of the riders out there aren't racing, either. As a matter of fact, the only time I can think of that I'm WFO is when I'm passing cars... so... let's see, I spend 95% of my time between 1/8 and 1/2 throttle.... torque curves at those throttle openings would mean a lot more to me as far as what this bike is going to feel like in normal day to day driving.
But, I can see your point - I guess for some riders, the only thing that really matters is how hard they can accelerate when they crack it wide open, and how the bike behaves the other 95% of the time is not as important. I can get that.
It's an interesting question - any input from other riders? How many people find a Wide Open Thottle dyno sheet to tell them everything they need to know about their bike, vs torque curves at different throttle openings?

 

I get your point.

I am positive my tuner has sheets with mine at different throttle openings from when he was tuning, but I had no compulsion to ask for them at the time. The left side of my WOT sheet seems to match the performance of my bike when doing my casual riding or passing cars.

But I do indeed do some racing with my buddies and occasional WOT blasts when alone.

I do see your point while cam shopping to see what they do at lower throttle openings. You have a legitimate point.

There is one flaw in Jamie's part open throttle comparison (and this is not knocking Jamie at all). Neither of these cams were set up with their optimal compression during that test. They may have behaved differently had he done so.
It would not have been practical for him to build an entire motor around each cam for a same day same dyno same conditions test.

If I were to use a part throttle sheet while researching a cam for myself, that sheet would need to be from a run where the cam was set at it's optimal recommended compression.

Low compression affects a cams performance significantly.

 

Thamks Jamie this does give a nice indication of what is possible with a stock 96 motor....
the 555 ALMOST acheives making it a 100/100 motorHave you a kit together for the 555 and tuner yet???
