Actually Bruce, the combo has been made up way before Charles came up with it, do u think that he told HONDA to make oversized pistons, and that he designed the "black mamba" cam, no that was ISKY, and he is definetly, not ARC either, so dont give all the credit to Charles, even though he is a good builder, and has many different combo's , but he isn't the only guy who can do that, just look real close at JD's builds, he does them all by himself, with little help from anybody and he definetly isn't Charles. I will say that it was because of Charles, that JD does this whole minibike thing, but JD has been building engines much longer than Charles and I am not talking about minibike engines either. JD has told me about building V8's for many years, but I wouldn't go as far to say that JD is the go to guy for V8 combos because of this.
As far as understanding, I can say that I gave Charles a example of two identical engine builds, lets see what he says about why they make different power, and how can back that up with his "calculations". Ask JD, there are many different things that come into play in this motorsport field that we all love and fight over, so there is no ONE person who knows it all, because there are just to many variables to "understand" why things are what they are.

Let me touch on the cam comment bro. Actually Charles did have allot to do with cam profiles in Tims early days and today as well. I believe Charles actually got his first cam specs from the Yamaha YF200 cam. Which I believe has the same duration as the 242, 270, 276, and 290 grinds ISKY makes. Now on that list is the 310, 330, 350, 370 & 380's. I'm pretty sure the Yamaha YF200 cam is the exact or maybe just a slight number change as the 242 grind that ISKY has been making for a few years now. Kick ass gasser cam BTW ......
But that is the exact example, you up'ed your stall by 600 RPM and now you was able to finally max out at 9340. Before you changed your stall was to low. If you would have ran 750 feet it would have TOPed out at the same 9340.
I can't believe why you still don't get it.
I guess you can't teach a old dog new tricks. I'm done with schooling people

So I guess school is back in session.
Ok, get ready to copy and save to your favorites. I will explain you all of you new guys learning motors how I know where Max TQ is without a Dyno.
On my bikes I normally have a tach. And my max TQ is at 5500, but I don't know this yet. So I purposly put on a clutch with low stall, like 4000 stall. I then jump on the bike and run it down the street.
This is the trick, so hold on to your pants.
The motor will then reach a RPM where it change sounds and acceleration speeds up. That is MAX TQ. You then set your clutch stall to engage 500 RPM before max TQ. So MAX TQ is at 6000 RPM. The bike starts moving and locking up the clutch slowly until MAX TQ where it locks solid and you get moving fast through the power band.
You see, no dyno is needed
Now, a bonus
The power band is MAX TQ - through to MAX HP. That normally is only 2000-2500 RPM. Sk a example is from 6000-8500 after that is over revving. Over revving sounds bad, but it's a.good thing in drag racing, because it's speed.
