It's been a long time not being on the sand April, 09. We wanted to run 300' sand drags sooner than this, but oh well. When we 1st went sand hill shooting we had naysayer's that our asphalt stuff would not work. We'll that got squelched pretty quickly.



Then we had 300' sand drag naysayer's. That how do you know your set-up is fast without a timer? There was much more to the story than that. The main topic was our clutch set-up. Anyway, there were disagreements on how things should be set-up for 300' drags.



The person issued a challenge of a 3 sec. pass within 3 runs and I wanted 3 times to the track. Well, I finally got around to his challenge. It was suppose to be at the PS DomeValley Race, but PS cancelled 2 days prior. The track decided to hold a 2 day race for us. We decided to go ahead & go.



1st run me riding (I weigh 210 lbs.)

1.339 60'

73.60 mph

4.037

Check out run



2nd Angel riding (his weight 180 lbs.)

1.314 60'

80.15 mph

3.909



3rd run me riding

1.364

74.35 mph

3.997



7mm Cub on race gas, stock frame, +14 arm, +1 forward on a-arms, front brakes, quad/rider 540 lbs.

22x11x8 12 paddle extremes, I have no choice!

We used 16/41 (2.56 ratio) on the hill, 1st gear launch (1-4 manual 5&6).

Right now I have it set-up for 17/42 (2.47 ratio) for a 300' baseline.

Clutch primary/base pressure is set between our asphalt set up and our hill set-up. Hill setting had too much base and I think the asphalt base would be too loose. Arm weights I'm keeping with the asphalt weight initially. Pretty sure I'll have to remove some weight.

Launch limiter set @ 10,000 & shift light @ 10,000 same as we use for 1/4 mile asphalt. Probably will have to lower the launch rpm some.




The only changes made during the event was tire pressure, wheelie bar height and rear sprocket. ;)

ATVDRA (Skip) & I was discussing my sand 60's today. Part of my reasoning for running the 300' sand was to get a comparison with 330' asphalt.

I was really surprised that our first attempt at the 300' netted the results it did. We have ran low 1.30 60's on asphalt, but that is a well sorted out combo. Unlike this hodge podge 300' set-up, that I thought & many others wouldn't work. Like usual, I used the tools I had available to make the best of it.

As for a 300' to 330' comparison. Well, we have more work to do. The 300' times are slower, but I'm really not complaining.

There are many factors that played into a good first outing. Like usual, I give the clutch management a good amount of the credit. ;)

Next time out we will be better prepared like: removing weight from quad (Front brakes), lighter rider's (still Angel & I), closer to the proper rear tire and a few other tricks.

Thanks Trinity Racing & Wicked Motorsports for your support!

Go Brian, go Brian!!!! LOL

Shows you what a good clutch tuner can do. IMO your 300ft times were not as strong because you had too much swingarm for the sand and your tires. I generally run 2 inches less arm on the sand than asphalt. But no matter when or how I have run my bike (or with wifey on it) my 300 sand times and 330 asphalt times have been within .02 of each other when they are tuned in.

No offense to anyone, but this is the stuff I like here!! ha ha Little do the guys that only run the sand realize that asphalt racers have the hardest part figured out first lol.

Thanks Bubba, that means a lot to me! I have the same mutual respect for you.

We had some problems mainly with the traction in 3rd & 4th gears. I'm pretty sure we have the solution to the problem, but I would like some opinions. The main problem with our combo was the paddle tire & that's where I would like some opinions. I know there are other areas to work on also & would be more than happy to here them opinions also.

I'm planning on running a couple big sand events next year if the events work out (like PS) in Mar. I don't really want to haul to Gilbert, LA., but if I have to, so be it.

I know I didn't set the world on fire with my runs, but I'm pretty sure I made a statement. I hope to improve drastically with the ET. I have a lot of work, but I'm up to the challenge.

I must also thank my Puerto Rico friends Angel & Noel. They are a big part of helping me, but they did have doubts on my combo.

DOING MORE WITH LESS, NOT LESS WITH MORE!

I figured you would start spinning the tires with that less of tire.

I also run a stock modded frame, basically we just cut it and stuck some mild steel in there to lengthen a bit. My bike weighs 330 with the bar, so we are very close to the same total weight. I dont have an elaborate clutch setup like you run, but when I started running the tire needed to get a good time then I had to start changing clutch for sure.

I run a 12 paddle staggered ripper in a 24" carcass on a 10" wide wheel. It measures between 76-77 rollout but lays down a very wide footprint. I can also run a 76" rollout 14 paddle staggered extreme on a 10" wide wheel. I tried to tell the guys we raced around for years that they were not running enough paddle, and the 60's were showing it. We've never raced out west, I know the weather is drier and better air conditions for the most part, but also I dont know how the sand is compared to what we run here. We run on more of a tilled "dirt" than sand, so you may have better traction on that track. My bike ran a 3.95 but with only a 1.42 60ft and for that track it was an excellent 60ft. Between the 2 tires I run the ET's are close. Seems like I gave up only 1mph with the rippers, but was a couple of hundredths quicker to the 300 mark. Hope that helps any, Bubba

Thanks for the tips! It pretty much reaffirms what tires we are thinking about. We will probably run a 14 paddle staggered extreme with 1 or 2 layers of kevlar, on a 24" or 25" carcass, but we haven't ruled out the same configuration with a ripper with no kevlar.

As for the clutch set-ups, we have been working with the standard lock-up set-ups for years. Both on asphalt & sand with great results. It takes a little more work and some design changes, but they are working. I hope to have the time to prove it this next year with 60' comparisons. The reason I say that is, our priority will be the race cars next year. Without them, I couldn't fund the money pit quad.

Right or wrong we got our new paddle tires. We ended up with 22x11x8 14 paddle Rippers on a 10" wide rim, with a 73" RO @ 5lbs.

We are working on reducing the weight. It was around 315-320lbs. when we 1st ran it. Hoping to get it to 300lbs. The riders are going on diet also hoping to shed another 20-25lbs.

The 1st race we are planning on this year is Bakersfield, CA. at the end of Feb. We know very little about the tack/event. Mainly looking to test the new tires.

Well, we snuck a race in this past weekend at Dome Valley, AZ. again. The new tire testing went well. We had a bunch of hiccups and managed to work thru them. The results worked out pretty well.

It was a big day for my buddy Angel. He got his very 1st win & I'm very proud of him. He's like a second son to me and the 3 of us all share the riding duties on our quad. Angel has always been a winner & anyone that has been around him will know.

Even though he considered this his first win, it's really not to me. It started with him riding our quad hill racing the 1st time out. He did such a good job on the hill. It was hard to even get a race in the afternoon. Then we needed someone to test our quad back East in 2010 for my son. He did a great job & won 2 grudge races to boot against a bigger bike on alky. He got them on the tree & out performed them with ET. Those are only a couple examples why he has always been a winner.

Video will come later when he sends them to me.

nevermind, i read it on Pro Sand Drags and copied it over here so you didnt have to write it down twice.

A little slower than the 1st time out. We had a bunch of hiccups and had to share the track. The dragsters, jeeps, trucks & cars makes for wild rides on the quad.

We were just starting to get the clutch dialed in for the Rippers on our last run. We did solve our problem with spinning in 3rd & 4th gear. I hit 80 mph over my previous best of 76 or 77 mph. Angel hit 81 mph over his previous best of 80 mph. We still need 1 or 2 more teeth on the rear sprocket.

Other than taking the scenic route (LOL) that was a good looking launch and pass. It looks to be a pretty good advantage not having to constantly clean out the bike and just concentrate on driving.

That was one of the less scenic routes taken that weekend. If you notice our left tire was sitting in a hole. That's why I don't like taking vid. I wasn't able to line him up a little more to the right. Anyway, I don't like running with the TF/Alcohol dragsters and the other 200 different types of vehicles that were there. Our straight runs came in the morning after they worked the track all night.

As for cleaning out the bike. We installed PJs a while ago to test using race gas. Everytime, I've tested them it's not as clean or crisp with them open. In the video we had them a half turn open. Normally the bike has very little smoke & really doesn't need any clean out. Normally we just wack it one time with no PJ.

We are always testing different items, but try & limit the testing during eliminations. Luckily the PJ didn't hurt us to bad.

As for the new 14 paddle Rippers, we love them, but have more work to do. We are not getting the RPM thru the traps we want, but we did pick up MPH with them. We are thinking we need 1 or 2 more teeth on the rear sprocket.

We are also testing the limits on how many runs we can get out of a clutch. We have 100+ asphalt runs on this clutch. We know that we lose a little performance around that number. That's the clutch we ran low 1.30 60's on in Nov. We now have around 40 sand runs on that clutch. We are planning to get one more event out of it with some creative maintenance. The base pressure is not right for the new tires yet!
