turbo, turbo, turbo

much time has past and my bike has been apart for over a year, but today it runs again, with many revisions and custom parts. I can not comment on how it works since it is cold out and there is much snow. it does sound wonderful, to hear it run after so long, it seems to have lost a lot of vibration...

Re: Turbocharging the Yan-clone L100: End of the Trail?

picture of intercooler partly installed, plumbing unfinished, pistons with material removed (lower compression), and lighter flywheel, will it be the answer? i have no idea, but will keep posting updates as they happen. the turbo on the v-twin works very well when the outside temp is arond 4 or 5 de...

Re: Turbocharging the Yan-clone L100: End of the Trail?

toyotaracer, are your cars gas or diesel? the engines we are using have many different challanges compared to a car engine, cam profiles rpm ranges being different, maybe the problem is the turbo is too small and there is not enough heat, volume and pressure being made to powr the turbo past the boo...

Re: Turbocharging the Yan-clone L100: End of the Trail?

you may want to think about another problem, what happens to the static compression ratio of 22:1 or 22.5 :1 when you add 9 or 10 pounds boost????? not many diesels run that high of a compression ratio when they have turbos http://www.rbracing-rsr.com/compression.htm you have to rethink the engine a...

Re: It's a Gusher

the 406/418 cc are vented only to the intake with no external vent.

dieselfly, you got away lucky, i had to make an oil seperator for mine, i did get it to work, but i am pushing the unit alot harder and the more boost the more leakage.

these engines are very poorly timed, the 2 pumps can be altered individually, fighting forces from in correct timing could also cause failure

its true, no one ACTUALLY knows the number of failures, it sounds like the rumors and bad rap that the GM 6.2l and 6.5l engines got from failed cranks, the problem with those engines was cheap owners, not replacing the failed ballancer, and about 6 months or so after the ballancer fails the crank fa...

Re: L100 TDC

this might help, but you also need to verify that the cam drive has not moved ,i.e. the key on the cam gear or crank gear have not shifted. the only other thing we have seen for a no start / hard start with a 406cc clone is a bent con rod, the piston was off and had too much leakage, but if you tort...

Re: Is 12amps output sufficient ?

the manual that came with my engine says it has a 15 amp charging system, they seem to print and say anything in the manuals, 12 amps might work for you, depending on how many lights you have on the bike, the main consumer is the headlight, everything else can be L.E.D. as long as you can maintain 1...

yes its true, i have a turbo on a prototype 836, so far i havent broken it, and i run it fairly hard, the turbo does increase power, i could pull 140km without turbo on a good day, and no it will pull 160km per hour, and the bike is 520 pounds, big heavy thing, so cruising speeds of 130 or so are ni...

Re: Yanmar dnepr project thread

it looks as though the ebay injector is for a 186fa engine and not the 186f, the fa is 418 cc and the f is 406 cc.

i have a picture of both, these are both chinese clone injectors not yanmar. i hope this info will help out.
