what wont work?
putting a turbo on pipsqueak 140 sized engines.
i beg to differ. it produces quite a nice bit of boost at just a bit over idle. no figures, i aint gotten to the point of fitting guages...
so far, just welded up some old pipe on the exhaust side to see if it actually would make some pressure... and it does
note the cat, before the turbo... i decided to stick it on as 1, i needed a bit more length, and 2, it was there, and 3, if its going to get stuck on there, shouldnt it be first in line so it gets hot enough to work?
doesnt seem to detract from the performance, at least.
so, i just fired it up, still no oil lines or intake obviously, squirting some oil down the oil feed as it warmed up (and cooled down, too) and well, yep. it makes pressure
probably only cracking 3 grand or so, and wee! you can hear it whining over the unmuffled exhaust! wasnt game to really open her up because of the (lack of) oil yet. just enough to prove im not on a wild goose chase.
the plan? going to try and get one of these new (stat write off) NBC110 posties from the auctions for its EFI system (if its not adequate, then i just strip it and sell for parts then resort to a piaggio or similar), get a brand spanking new lifan 140 (my favourite engine) and fit it all on to my old C50 frame. after making sure it all works on the pitbike, first, of course!
i started doing courier work, using a ninja 250...its fun, but i really want something that 1, can carry a decent load, and 2, something distinctive and possibly with a comfier seat... 10-12 hours on a bike, 200+km a day...yep, you get a sore butt!
and of course, we all know lifan 140's are virtually bulletproof, cheap, and theres plenty of upgrades for them... also have relatively low CR as stock.
so, a challenge will be plumbing... firstly, oil supply. cant just tap into the oil cooler lines as they run a bit too much pressure, and the drain needs to be as "free flowing" as possible. ie, straight into the valve cover. see how using a flow restrictor and a double banjo from the oil feed works at first, but i suspect i may be modifying a head-mount oil feed block thingy.
may require a small water cooling setup... turbos get freakin hot, and it will probably pay to set something up, seeing how often i have to stop and start. small radiator from a water cooled PC, and a pump, should just about do it. probably not a good idea to trust thermo-siphon circulation alone, though ill try it at first.
then theres the engineers cert but i think it should be right as long as i am sensible... probably swap the forks over to a disc brake front end, that should be enough to satisfy from what i gathered with my brief talk with one a while back.
but so damn what! i got boost! BOOOOOOST!
