    racing, cars, customizing, reading!!!!!!!!! I currently race the east coast series UTVRR, rally raid racing, in 11 season my team mate and 9 finished 4th and 5th respectively in the stk. class with the only 2 joyners in the series. I am shooting for winning the points this year in our class so cheer us on, "Slingshot" grabs attention everywhere she goes!!!!!!!!!!!!!!!!!!!!!!!!!!

  2. SHOWA, i haven't started putting steel down yet,still on the cad cam system at the moment and buying up parts as well! As soon as i get to putting the steel down in a "going forward to completion phase" i will do a series on the build! Thank you very much for the compliments on "SLINGSHOT"! She is very near and dear to my heart and at some point and time things have to change, for what i'm wanting to do for racing i just can't bring myself to do to her, i would just assume let another family have her and let her bring the attention and enjoyment to them that she has brung to me and my fami
  3. Got my baby "slingshot" for sale, she is a 2007 sandviper, outlaw utv's body kit, brockwell tuned engine, race prepped trans, corrected rear end geometry and race reinforced, maxxis big horns,quick diconnect steering wheel, limit strap on rear,halogen beam off-road lights, this buggy to build again including the purchase price would cost well over $8000.00 Price is $3500.00, price isn't negotiable! Building new bike powered r1 and just don't need 2 of them however don't have to sell it. Will let 8'x14' diamond cargo black enclosed trailer go with it for a extra $1500.00. Great deal to eit
  4. Really a good analogy lenny, and pretty close there as well, our race engines have benefited from this practice for a few years now, as well it makes them have a real crisp raspy sound that just throws people for a loop! We are big fan's of david vizard a world renowned mechanical engineer that applied alot of theories to racing, he also made a believer outa us on dimple motors and fire sloted pistons with less timing! The more timing you got in a motor the more it is trying to fire the motor to go bsckwards when fired on the compression stroke. With all the correct applications applied to a m
  5. Lenny, for the most part i agree with what you are saying however a few years ago i was able to set in on some would consider to be "secret" workings in racing and was able to watch several different motor configurations hence 2,3,4,6,8,10, cyl motors with die in the fuel run in a black light room, the lesson i learned was unreal, a motor inhales and exhales almost as we do and the gas that comes out the top of carbeurators is unreal. The point being the when correctly placed reversion dams in the flow path makes a motor a much more effecient machine! This is not as prodominant in fuel injecti
  6. So i am at the point that i am thinking about popin the intake and exhaust off my 800cc to see if port matching them or if they need matching! The exhaust shape is like a D shape, kinda strange to me but are wanting to know if anyone has looked at these motors before and if they have poor matching from the factory and could benefit from this expotentialy! if the intake manifold is smaller than the intake of the head but by just a little then i'm good with that, if the exhaust is a little bigger than the exhaust port, i'm good with that too, so, anybody been into one and does anyone know who ca
  7. Lenny, looking at the other sites you gave me i'm just not sure i understand what i'm lookin at here being's that i'm not into the computer end of these things. If it were posible then it would be the way to go! Also Kinarf, would you have any idea where to get a sensor like that? I looked thru your pics on your rebuild, if you don't mind me asking, where did you get all the specs for rebuiling your motor? You know like tolerances,torque specs,etc.?
  8. i p.m. him with this topic, if it becomes a poibility all i will need to nail down is how to time the motor and how much timing the motor can take. Dosen't seen to be that there is a "known" timing for these motors, do you know of anyone that has attempted to do this or where to get the specs on the motor totally? i think if i can get all of this info and be able to manipulate the timing then the sky will be the limit on this deal. Also does that sensor work off of magnatism or how does it read the position of the flywheel?
  9. we have looked at that before, the problem is that the sensor on the flywheel is not mounted on the same radius as the flywheel is. the sensoer is mounted on a flat surface on the top of bell housing and if you move it left or right on the flat it moves either away or closer to the flywheel inside the bell housing. Without knowing more about how the sensor works we feel that doing that may interfere with the signal sent back to computer. Just out of thaught here not stating a fact but just upon examination that's the way it appears physically!
  10. 2scoops, thanks for getting in on the convo here! Yes sir we are having to stay naturally aspirated, we are looking at any and all advantages that we can get where it all looks to be stock, we have made all the factory tweaks we can we believe but are looking for more, lenny had made a suggestion to contact silverbullet for cam's for the 800 with the same cam grind that the 1100 has, would love to find a controller for the 800cc. I also wondered if the intake and exhaust ports are restricted by bad factory match ups per each component and would it benefit to take a look into it port wise. The
  11. well it would be safe to say that the gas tank was the problem! no skips,spitts or sputters! I would suggest that thi get put in as well when someone has fuel problems, thanks for the help and the info guys, you were all a tremendous help and a wealth of knowledge, my hats off to you all! Thanks, Mike
  12. Here we are fixing to go thru tech for round 2 of the UTVRR series, all went fairly well until lap 3, it had began raining about 20 min before and when in the technical section of the mountain cliffs i caught a 4" small tree stump with left tie rod and spun me counterclockwise down the hill flipped up onto my passenger door backwards on the trail. Another racer coming down couldn't stop and hit me head on and actually rightsided me up and into a dig out in the side of the mountain!!!!!!!!! From that point on i limped it back with a bent tie rod and parked for the evening, the rain was ter
  13. Well the results are in..................................the fuel injection sump in the bottom of my gas tank was torn aloose from the bottom of the tank and was turned catty corner in the gas tank, was holding the fuel gauge at about 3/4 a tank and wasn't even close. I had another tank that i had from a sand viper we put a zx1400 bike motor in left over so i gave it a real good cleanig and installed it into the racer, so we will see if that was the culprit next weekend at the races, ran well around the property so cros your fingers that's what it was, were loaded and ready to race next weeken
  14. there actually is a a x-dwarf car on you-tube that has been converted to a long travel sand car, look it up not sure what the name for the video is but it's there. BITD series is some serious cash there no doubt, but there is a need for all the utv's such as ours to have a place to race, the guy that brought our class together built it so that the hobbiest could afford it to the serious with different classes to work with all budgets. As more people are learning of our type of racing more are coming..............so as the old saying goes....................build it and they will come, you guys
  15. AH, the good ole dwarf car days lol, have rolled my fair share of those little dudes..........................and can hear alot less because of'um lol! The joyner is alot quieter in comparison. We still have two cars left,motors, jigs, and spare parts, kinda miss it but don't miss all the cryin and whinnin and people wantin to fight GEEEZZZZZ! Nice to be in a sport where all get along and help one another and at the end of the night, we all sit down and talk about the evenings happenings, kinda like the "i caught a bass this big stories" LOL!!!!!!!!!!!!!!!!!!!!!
