Turbo 2 Stroke Carb'd
 

Hey, i'm new here I searched around the forums and found some stuff nothing too specific.

Anyways i just finished Throwing a turbo onto an older snowmobile i got for free.
Its a Turbo off of a Ford Probe (1990 i think)
Mikuni Carb
1982 377 Skandic Sled

Anyways i was just wondering if anyone has done any tuning on this sort of a set up.
Or just some info on this sort of thing

I got 4-5 psi out of it today with nothing restricting the exhaust.

Ill post some pictures tomorrow.

what did you do to the fuel system to run 4-5 psi? turboing carb engines are very tough to tune not to mention your doing it with a 2 stroke engine which makes it even harder.

I had a Jet off of a 198x (low 80's) Arctic cat 5000 Same carb bigger jet...Thats all i've done to it.

I've looked into turboing a two stroke before, most people said it seemed unlikely to improve performance because two strokes have open ports so any boost made would likely escape through the exhaust port. I'm hoping you prove that theory incorrect, keep us updated.

what are you going to do about turbo oil feed and drain? theres no engine oil pressure or crankcase so your going to need an oil pressure supply pump and a return sump to lubricate the turbo.
did you check the a/f ratio when you did this 4-5 psi run?

if you have video capabilities, i would love to see a video of it running and going into boost.

I have some more pictures ill post later on.....I can get video maybe sunday as i am out for the weekend

I will get my buddies helmet cam and try to mount it somehow i am also intrested to see how this video is going to turn out.

So Here is what i did for my oil setup. I Managed to run it off of The existing Light wiring that was there...

nice pics,are you sure that bilge pump gives necessary oil pressure to turbo?

Hi, looks like a fun project. I'm working on a yamaha turbo sled myself. A couple things you'll need to do are; put an expansion chamber in the exhaust with the turbo at the end of it, stock pipe will work. You'll have to fatten up the mixture as well, raise the main needle a notch and install a power jet. Route a tube from your airbox to the top of the carb, above the slide, if you don't, boost pressure on the underside of the carb slide may cause it to stick wide open. Using some sort of EGT monitor like a "digatron" to find the right mixture is a good idea.

Any video of it boosting? :D
