Apex/Attak Clutch Survey

[black700]

[BADSLED]

I'd like to see a POLL for this one.....

 

[BADSLED]

I agree with "BBY" on this one

I think youd be surprised what gearing down will do for you in a drag race vs. stock gearing. Ill leave this post her for a bit, but should have been posted in the clutching section...BBY

I ran 4 setups in my attack last year.

1. Stock. It works great. However it has a terrible flat spot out of the hole. You can very easily run away from the stock clutching out of the hole with a clutched Apex or attack.

2. single speed Heel clickers. They worked better out of the hole then the stockers. But they didn't run as good as the Ulmer or Proline.

3. Ulmer stage 2. This setup flat rocked out of the hole in drag race form. It also performed great corner to corner in the trail. However I had one of the original setups and from a 30 to 50 mph roll the stock clutching would pull away. I believe Allen has since addressed that issue.

4. Proline. For 660 racing this setup was the best I ran. The Engagement is high and it rockets out of the hole. I would say with some Minor adjustments via a spring a weight change the Ulmer would just as good or better in 660. I would say the proline was 1 sled quicker in 660 compared to the Ulmer trail setup.


The nice thing about Ulmer's kit is you can adapt it for any occasion "off trail, tight trail, wide open trail, Mountain, or drag race" That's the beauty of a kit that offers tuning options. The Proline isn't user friendly that way. the weights are what they are. Could drill rivets yes but you will never had the wide range of adjustment you get from the Super tips in Ulmer's kit.

Great post, thanks

No problem.

Flat spot is a lean condition that I am experiencing in my attak right now. The more aggressive the clutching & better the hook up the worse it is. Gotta richen up the low end. Sled totally falls on its face unless i spin hard or back off the clutching. For best performance the sled must be fed more fuel down low but that is for another topic!!!

I am running the ulmer kit and i am quite happy with it. I like the adjustability, and the tech support when needed. Although, i will encourage everyone running the ulmer setup to experiment with the weight setups and find out what your sled likes. the setup that comes in them is a great starting point, but you might be able to do even better. As was said before, traction is a major issue with the apex's with any clutch kit, and studding outside the rails in every lug will give big smiles if your looking for max acceleration.

I can also say there are some guys running stock wieghts and really making them work. We have a couple apex's (one with stock primary and ulmer helix, and another with ulmer stage 2) giving 185 hp flannery polaris' and nos mach Z's fits. They aren't beating them every single time, but always close enough to throw a blanket over all of them, and that is pretty good considering we are at a measly 150 hp! Those other guys just shake thier heads.

Agree and thats why I installed the Hauck Fuel accelerator.

An interesting comment from a bud with a Chuckaroo cluthced Mazh Z and 800 rev with the bondi 165 hp kit was, I just cant believe how well your sled gets out of the hole. Doesnt matter the condition, it just comes out so much harder with the right fuel mixture down low. Last year they were getting the best of me most of the time. This year, its a whole different result...BBY

I didn't experience the Flat spot with other clutching. Every sled is different.

Now wait till you can add some timing to it as well, it gets even better!

How many Miles do you have on your sled now??

 

[BlueByYou2000]

Maybe 1500 or so. But have tested it with box unplugged and without accelerator being hooked up, its no where near as good out of the hole. The throttle response is just so much better with the box on...BBY

Every sled is different.

I feel similar, sleds can vary one unit to the next. That is why I cant wait for Ulmer's set up, it is tunable!
