05 UC with Ohlin mono shock, anyone running a similar setup, if so what setting do you have that work.

Is it a TTX like on top, or a LMP like bottom photo?

All TTX dampers will say TTX, where you see it top photo with two clickers on canister side

Looks like the TTX, it has 25 clicks on each ext and comp.

TTX you wanna run the compression tight, relatively speaking, dragster. That's a twin tube so no matter how you adjust the rebound clicker won't affect compression damping as it would slightly, if it were a mono tube (LMP).

I'd start in the middle on rebound, and go from there. Two, three, four, five clicks from tight on compression, dragster.

Mono shock dragster, I should say.

Yes mono shock dragster. 1.01 -60's 4.50's

Any video?

No video - here is the problem - car repeats great until track gets a little iffy, then it moves around on the top end at times to the point of lifting. Shock is currently set on 17 rebound and 13 comp, may need to reverse those but test and tune normally consist of a couple of time trials and go race so was thinking someone maybe with same setup to get me in the ball park. Never a problem on the starting line only on the big end.

Because of the design of the TTX - twin tube, the seperating piston is smaller in comparison to a monotube design - LMP. Plus the fact it's a mono shock - 1 shock, I'd suggest three, four, five, maybe six clicks form tight on compression, to keep it up on the tire at speed. If it feels too tight on the time run, take a couple clicks off it.

In the middle of the adjustment range on rebound, twelve or thirteen clicks from tight.

Thanks - will give it a try

You're welcome sir.

you can play with settings wont hurt to learn,i think they are close.shock isnt goint to help on top end .likely to much air in tires.top bar down may help also.remember whatever you do for down track will affect starting line in some way.what tire do you have now don

Don, sending you a private message.

Rusty - Tire is the Big Bubba. 6 lbs of air. They are about 1 1/2 years old with not that many runs as I missed all of last year.

Pinion angle?

17 and 13 clicks clockwise or counter clockwise?

1 1/2 degrees -- Clockwise

I'll cover this first.

So whenever you discuss clicker settings, the correct terminology to use, is to discuss it from tight (any brand).

From tight would be counting clicks counter clockwise in this case - Ohlins TTX 36.

So you're actually at 8 clicks from tight on rebound now, and 12 from tight on compression.

I'm suggesting 14-15 from tight on rebound and 6 from tight on compression.

It's not a huge change but a tighter compression will hold the extension of the damper, you see in the video I posted. That's what you want, the damper extending.

The phenomenon is the same for every drag car, the pinion crawling the ring gear, applying the tire to the track surface. You might even try working a little more pinion angle into the mix at some point.

This ohlins damper you have, you'll find you love it, once you identify what it wants for clicker settings, in correspondence to power in play, instant center, pinion angle and spring rate.

Good info - thanks - will give it a try hopefully this weekend.
