XX4me Posted September 3, 2004 Share Posted September 3, 2004 After thinking that the clutch was slipping during my previous dynos I bought new clutch plates and stiffer Orient Express clutch springs. My previous dynos were done with the boost set around 8-10 lbs and had some boost creep up that took it up to 12 lbs at 11K rpm. I made a two stage boost control system using a solenoid and bleed valve that is activated by my high beam switch giving me a low stage of 8-10 lbs and a high stage of 17lbs. There are three runs on this chart, two are high boost and one is low. You'll notice that the two runs on high boost stop at about 7500 rpm that's because the clutch just let go. Seems the boost and HP were climbing too fast for the clutch to hang on. Bitch about it is it didn't feel like it was slipping on the street and now I have no idea how much she's really making until I can get a lock-up clutch.

Northman Posted September 3, 2004 Share Posted September 3, 2004 Wow, I'm surprised the clutch still couldn't handle the power :???: Damn shame mine won't be ready for NeXXt, or this would have been a lot closer than we both thought :wink: Get it sorted before next season, Forrest, and we'll play in Arkansas.

No way Dude. On the street I didn't notice any slipping on high boost, only insane worm hole like accelleration. 4th gear @ 148 mph the bike's trying to rip itself from my grasp and the front end wants to lift off the ground. I'm not :poke: at you I just think it wouldn't have even been close, this thing is scary. Quote Link to comment Share on other sites More sharing options...

RichardCranium Posted September 3, 2004 Share Posted September 3, 2004 Just throw some Marvel Mystery Oil in there. That should fix your clutch problems. :twisted: Quote Link to comment Share on other sites More sharing options...
demon Posted September 3, 2004 Share Posted September 3, 2004 You gonna go with a MRE or an Elton Fish unit? Looks like a billett basket and a lockup are in order. Don't know if they offer a 2 stage lockup for the bird though a single stage is readily available. If you were gonna do a lot of dragracing with it, I'd go ahead and get a cable clutch conversion as well. It'll let you "feel" what the clutch is doing a lot better and you can adjust the travel and freeplay to your liking. Elton has the lockup on an exchange basis (clutch cover) and also offers the cable conversion. Dyno is pretty impressive till the cluch let go. 17 PSI.......tasty Quote Link to comment Share on other sites More sharing options...
Violent J Posted September 3, 2004 Share Posted September 3, 2004 Don't know if they offer a 2 stage lockup for the bird though a single stage is readily available. MRE does, I have one. MTC does too. Quote Link to comment Share on other sites More sharing options...
XX4me Posted September 3, 2004 Author Share Posted September 3, 2004 Looks like I'll be in the market for a lock up. Violent J if you have any input as to what you think works best let me know. I mostly use the bike for street riding/racing. So I want something user friendly around town. Elton does indeed offer a complete set up, but for something like $1800. :shock: I'm hoping to set it up for a little less Quote Link to comment Share on other sites More sharing options...

XX4me Posted September 4, 2004 Author Share Posted September 4, 2004 Thanks guys but it would have been more impressive if the clutch had held and it hit the magic "300" mark. I'll give it another try later. Quote Link to comment Share on other sites More sharing options...
Pete in PA Posted September 4, 2004 Share Posted September 4, 2004 I pulled out an old Sport Rider where they did an article on a Hahn turbo XX. Stock clutch and they got 214 HP on the dyno. You sure the rear tire isn't slipping on the dyno drum? Quote Link to comment Share on other sites More sharing options...
XX4me Posted September 4, 2004 Author Share Posted September 4, 2004 Nope the tire wasn't slipping. We had it strapped down pretty tight. On low boost it made 235 pretty consistantly. Quote Link to comment Share on other sites More sharing options...

I've heard a MTC 2 stage is way easier to set up. My is set up with no weight on the arms so it doesn't lock up hard until you hit about 6500 RPMs. I ride it on the street every day to work. Get a billet basket too. I got mine from Fallicon, MRE or MTC probably makes them too. Quote Link to comment Share on other sites More sharing options...
Violent J Posted September 7, 2004 Share Posted September 7, 2004 The real pain with a lock-up is that you will need an air shifter to shift under full power. Or, you will need to train yourself to shift without the clutch (blip the throttle while pre-loading the clutch lever, or just get an ignition kill button and preload the lever with your foot.) You WILL rip the bolts out of the case trying to shift when the lockup has pinched down tightly. (Unless you tune it to be JUST tight enough to not slip.) I use a Translogic electric shifter because at my local track to run in the street class you can't have an air shifter. Works great, alot of road racers use them too.
