coronakidd Posted October 31, 2009 Report Share Posted October 31, 2009 motor: 18mm or if your going that big may look into the 20mm's dm/dmx: billet cases is a must for reliability, the trans i would at the very very least run a billet 2nd gear set with a 1-5 override. carbs depends on the builders suggestions 39-44's is normal. pipes same again, custom built ones for that specific motor would cost a little more or which ever is found to work best at the time.. the lock up is deffinitly a must as well, the way that they work is centrifugal force pulls the arms that the weights are on out away from the center, the arms are pressing directly onto the pressure plate holding the clutches together.. with that being said, the mattoon clutch system would work better for the bigger motors i would think. an 18 mill dm or 18 mill dmx will run with or out run alot of the 20s motors 20 to 26 if i was going to speed the money to build another big motor myself it would be a tripple of some sort if i was going to stay with a twin i would run a spreed bore cougar or caracal ive seem a 26mill cougar run strong as hell (with 18mill tripple twister)the tripple snomo motors are fast if your going to go big go real big do a cougar or tripple or even a tripple cougar because if your going to build over winter you better build something thats the biggest out there now cause race time next year it will be to small and something bigger and faster will new and out at the track somewhere Quote Link to comment Share on other sites More sharing options...
PaddleShee Posted October 31, 2009 Author Report Share Posted October 31, 2009 A spread bore is basically 2 individual cylinders side by side correct? What's the significance behind running a spread bore? Bigger bores? More HP? What sizes to cougars run? 14,16,18,20 mil and bigger correct?

Koolguyson Posted October 31, 2009 Report Share Posted October 31, 2009 cause its already set to hold up to the bigger motors, you dont have to have that clutch system but ive seen 8-9 plate hinson systems with extra weights on the lockup not hold to 14mm dm's torque and show better torque numbers on the same dyno with the mattoon system, and we're talking about a bigger motor than that now. I run an 8 plate... Quote Link to comment Share on other sites More sharing options...

Bigger bores? More HP? What sizes to cougars run? 14,16,18,20 mil and bigger correct? A spread bore is 120mm center to center. A stock case is 102mm. If you build a spread bore you can't run in the normal classes at a PS race. You can ONLY race against other cougars. It is silly to even recommend a cougar right now because they are not going any faster than a non-spread, plus they can only race in one PS sanctioned class (which is sounds like he is interested in). If it is your first motor, don't build a triple. The Puerto Rico guys are crazy...lol, you have to watch yourself around them guys Quote Link to comment Share on other sites More sharing options...
rb0804 Posted October 31, 2009 Report Share Posted October 31, 2009 I would go DM/DMX over twister personally. Cheaper and faster. I wouldn't go cougar until they are a little more figured out. Even an 18mm DM will need a billet trans with you on it. Remember, your weight puts stress on all the parts. You don't want to cut corners on a big build. It will just cost you more in the end. A complete billet trans like the one WCR sells or just a billet second gear? What is the upper HP limit of the stock type tranny? Quote Link to comment Share on other sites More sharing options...
Koolguyson Posted October 31, 2009 Report Share Posted October 31, 2009 A complete billet trans like the one WCR sells or just a billet second gear? What is the upper HP limit of the stock type tranny? The only company that manufactures billet transmissions is Robinson. They make a full billet 1-4 (billet shafts, drum, gears) and a billet 1-5 which uses billet gears and stock shafts. Upper limit IMO is a true 140-150hp. My buddy has an 18mm DM and explodes a stock tranny with the billet 2nd set everytime he goes out. Matt Shearer had the same problem. It just isn't worth it IMO to skimp on.

No Limit Powersports Posted October 31, 2009 Report Share Posted October 31, 2009 Awe come on Sonny. Dont get mad....lol. AVI will be a blast. I hope I get to do some racing. Its still unclear if I will be piloting a bike yet. All of this dieting and it could be for nothing . Someones getting kicked in the nuts if that happens. And if he reads this, he knows i'm talking about him . LMAO your wife will appreciate it anyway tim. I told you i will let you make some passes and i will, dont worry. Im going to be getting the dmx on the dyno maybe this weekend to see if we can brake the chassis again lol just messing with you man. Chris isnt going untill he is on the plane and we takeoff. Ill tell you what as soon as the race is over ill take you guys out for a big ole steak and you can just go crazy. Chris told me that garrett is wanting him to ride there turbo dmx in the unlimited 650 class so if he does that you can have mine and all the spray you can handle .

PaddleShee Posted October 31, 2009 Author Report Share Posted October 31, 2009 Cougar is a spread bore correct? Whats the line up from smallest to biggest. Stock,,cub,,super cub,,Cheetah,,Dm,,Dmx,,Cougar etc etc?? Theres no way i'm gonna build a tripple right off the get go. I'm leaning toward a cougar perhaps a 18 or 20mil. Should get my weight down the track nicely. Quote Link to comment Share on other sites More sharing options...

J-Madd Posted November 1, 2009 Report Share Posted November 1, 2009 bigboybanshee is probably close to your weight and he has run 3.8s I believe on his 10 mil DM. If not 3.8s I know for certain he has run low 3.9s. Quote Link to comment Share on other sites More sharing options...
