It's video time

Could be, but the D/stock is already running 20-tooth sprockets (I think? Could be wrong...) on the finals. Heck, it tops out at about 47, and that's with a dinky 440 and no real other mods. The Chap should put out nearly 10 more horse than my ULII-02. That ought to be enough to push it to 48. The D/stock is really quite stock after-all. That Superchief is just a fine sounding machine. Listen carefully, and you can hear it pull from the bottom end. I don't think he's topped out when he passes the camera.

It looks and sounds great! Do us all a favor and count the number of teeth on your front sprockets if you get a chance. I'm betting it's 20 or 22. If it's higher, we're not speaking . I don't know what the lowest factory-installed number of teeth is/was. It's cruising, for sure. Constantly awaiting more videos...

Will do Im not gonna be around it for a day or so but if my memory serves me right it had 22 tooth sprokets and 26 tooth. By the way i need to thank Don he has helped me alot over the last year.

My two Chiefs have a 22-20 setup. My newest machine, a Super Chief, has bigger rear sprockets so I'm guessing it's a 26-20 ratio.

I'm not sure but I think every machine I own has 20 on the front sprocket. I've always thought the gearing reduction happened on the sprockets being fed by the T-20 (middle and rear) and the small sprocket on the middle axle and the front axel were slaves to everything else (the teeth on the T-20 and the sprockets it feeds).

Either that or it's just coincidence that all my machines have the same number of teeth on their front sprockets....well, at least the Colt and the two Chiefs do.

Good point George. I don't know where they changed the gear ratio. I have seen a couple different front sprockets on machines. I'll have to double check the D/stock again to see what the rear tooth number is. Hmph. Maybe I should just throw a Chap. in there. :o(

You're absolutely right, George
The sprocket fed by the T-20 controls the gear ratio. That's why the middle & rear are the same size. The Spider has 22T middle & rear & 20T in the front. The new Super Chief I have has 20T sprockets on the front & has a 26T sprocket driven by the T-20 & 26T in the rear. From the middle to the front are just 1:1's. Now we're talking about a 4 chain Attex. What's the driven sprocket on a 6 chain Attex? My guess is that it's the same - 22T or 26T. On a Max, the T-20 drives the sprocket on the jackshaft , the sprocket from the jackshaft to the middle axle are 1:1's & from the middle axle to the front and rear are the same. I'm thinking I should put the 26T on the T-20 & a 15T on the axle & head for the Bonneville Salt Flats. It probably wouldn't even get up my trailer ramps though.

Took some clips of the Sur-terk from the Gearz DVD. Buy the DVD! It's well worth it!!!
