turbocharging a 2 stroke or 4 stoke engine
 

I need a good website, article, or furom that has something on it. Im thinking of turboing one of my junk quads or dirtbikes. there has to be a good website out there if anyone can help me. ;D

Re: turbocharging a 2 stroke or 4 stoke engine
 

a 2stroke motor has a very high cr

they do make turbo's for small apps like 4 stroke dirt bike motors but i havent yet found one. but keep me informed if you find one

Re: turbocharging a 2 stroke or 4 stoke engine
 

Turbocharging a 2 stroke doesn´t destroy all exhaust resonances, you have to place
the turbo after the expansion chamber. And match the turbine and housing
carefully against the resonances in the pipe.
Turbocharging a 4 stroke is nothing compared to doing it on a 2 stroke,
at least if you want it to be somewhat drivable.

Ive seen a turbo on a harley cruiser before, i was looking for one for a turbo go kart. Ive heard from some people off carolina hondas who had turboed a go kart, but it only ran for about 2 days before it grenaded

Re: turbocharging a 2 stroke or 4 stoke engine
 

::looks at sig and avatar:: I heard HMT was a good site on finding out how to turbocharge something ;) What do you want to know?



lol, yeah maybe if you consider 6.5:1 C/R really high. I bet your thinking about a diesel 2-stroke.

Re: turbocharging a 2 stroke or 4 stoke engine
 

Mine had 8.5:1 stock. Not sure what it has with the head/dome I have on it. I have a few different ones to either lower it or raise it.

heres some turbos off harley's, i think theyed work great problem is there prolly not to east to find. They did make a sprint turbo. Its probably one of the smallest turbos ive seen and would be perfect for something like a 4wheeler or dirtbike.

Re: turbocharging a 2 stroke or 4 stoke engine
 

how do you plan on turbocharging a 2 stroke. i work on 2 strokes all day... the exaust port on the cylender walls is above the intake port. if you sent presureized air in there most of it would be lost out the exaust port. it would also probebly blow out allot of the exaust gas and make the combustion chamber extreamly hot since theres way more oxygen. because it would be blown out by the compressed air. you would probebly end up fouling plugs like crazy. and how would the fuel injectors work? you could use them like how itb's have fuel injectors right up next to the port but seems like the turbo would blow out allot of fuel out the exaust port. 2 strokes are real picky

Re: turbocharging a 2 stroke or 4 stoke engine
 

Werd I've been reading all over on if it's possible to turbo my 2-stroke moped, and I hear over and over it's damn near impossible for those reasons

Re: turbocharging a 2 stroke or 4 stoke engine
 

Just like a twin turbo D series in an EF. Mr.International won't let us down. ;)

id like to see it ;) because if he gets it to work id have me a badass 1200cc 2 stroke pwc

Re: turbocharging a 2 stroke or 4 stoke engine

we sell the 215hp sea doo rxp's at the dealership i work at. to bad there 12 grand. we have one turbo polaris from 2003 left

Re: turbocharging a 2 stroke or 4 stoke engine
 

Sorry to say but I'm going to be a let down. :-\ Reading this thread I just realized that its impossible to turbo a 2-stroke so I'm not going to even attempt it. Even though 2-strokes pules twice for every revolution so they have a shitton of exhaust energy to spool a turbo. Also a fuel injected 2-stroke would also not work becuase running premix through injectors is impossible, just look at the RX-7's. So if people with no first hand experience with turbos and 2-strokes say its impossible, it must be true.

370cc, 175hp:

Again, a turbo 2-stroke is impossible and should never be attempted by anyone, ever. Especially if your attempting to build a fuel injected, turbo Banshee running on alchohol. ;)

fuel injectors on a 2 stoke. never said it was impossible.

but what are you going to use to close the exaust port. or how does the compressed air stay in the cylender if it hasabout half a stroke to come out of the cylender. and are thoes yamahas running fordged pistons. because most 2 stroke pistons are thin and weak as ---- and feel like toys.


unless. the compressed air kinda just keeps flowing through the turbine end of the turbo creating kindove a jet engine effect.. presureizing the header charge and cylender all at the same time .creating about equal presure all the way through the system..... just trying to think ???

Re: turbocharging a 2 stroke or 4 stoke engine
 

i seirously kinda want to know. because to scale 370cc/173hp 1200cc/564hp. i would like to have a 564hp personal watercraft ;D

Re: turbocharging a 2 stroke or 4 stoke engine
 

---- you. I'll still eat you in Glamis. >:D

Re: turbocharging a 2 stroke or 4 stoke engine
 

lol, how long do you think stock 2-stroke pistons last? :-\ My motor is .30 over with Weisco pistons and a welded and true crankshaft. My motor is good to 240hp until the trans gernades. If you really want a 564hp watercraft than stop making excuses for why it won't work and go build it. And also the ratios don't work like that, just becuase a supra can get 1000hp on a stock 3 liter doesn't mean my 1.5liter Honda is going to make 500hp. All motors are not the same

Re: turbocharging a 2 stroke or 4 stoke engine
 

Just about every aftermarket 2 stroke piston is forged and very durable. I've never ran anything but Wiseco forged pistons.
Thin and weak my ass. These things are a work of art.

Re: turbocharging a 2 stroke or 4 stoke engine
 

stock motor pistons are. ill send you one they feel like there made out of alumnium cans. i know the ratios wont work, i was just making ---- up. but anything over like 230hp im cool with. because smoking some douche on a 12k dollar boat with one i built from ---- sitting around the back in the shop would be awesome. i just put a set of weisco fordged pistons in a bombardier friday because the guy hyrdolocked it and fucked his sea doo. not tryin to bicker like an ------- here I just want to know the physics of it. any links to these guys who do the yamahas?

Re: turbocharging a 2 stroke or 4 stoke engine
 

No need to send me one. I've seen plenty. ;)

My babies first piston: :)

It still help up pretty god damn good for a stock poopy cast piston. I raped the hell out of that thing.

Here's a set of pistons that lasted 2 seasons. I've only ever broke one pistons and I beat the ---- out of my bike like its going out of style;

I like when people say it can't be done, its just more of a motivation to get off my ass and do it.
