Guess it would stop the venturi effect working,


Would U like me 2 explain the venturi effect to U or some thing?
The more volume of air going through the carbie from the turbo on HIGH revs would only increase more fuel flow. Ether flooding the motor or creating more combustion.

With idle the turbo spins very little, there 4 very little pressure if at all on the fuel line.

So I don’t get where Ur coming from.

NOW HEAR THIS!!!!!!!!!!!!!!!
P.s. ppl read the (RCU Policies) before opening Ur mouths.
I won’t reply 2 ppl that cant say anything other than complete negativity.
when did this all have 2 turn in2 a debate. the motor works Excellent.
what do I have 2 prove
stop Or I will be forced 2 leave this forum. OK
I am only trying 2 give ppl ideas on making new things.

Don’t get me wrong constructive criticism is good


Willdo Would U like me 2 drive my Subaaaaaaaaaaaru over there?
With a blow up DOLLY 4 U. Then I will finely C U happy.

Status: offline 		Hey Willdo looks like rugby isn't popular in the states . I recieved my planes for the Wren turbo-prop today, looks like it will be a cool project, 7+ hp from a 1,8kg engine. Fuel comsumption is about 190ml/min. What a beast

Tim, chill dude the more wound up you get, the more of a target you will become.

Status: offline 		tim, I suggest you do some reading on the work of bernoulli, it will help you understand venturis
I can see you are on the defensive, but open up to advice given and make truthfull comments on your endevours and I am sure you will get a much better response

Status: offline 		does any one have any links to a pro made turbo setup for these little engines, i would like to study up on them a little more
all of this has peaked my interests, and im thinking of making a turbo myself, i understand the basics, but im a little rusty on all of the specifics.

I saw a unit intended for model cars being sold a year or two back, but of course it didnt work, the rc car guys tried to convince themselves it made power but it was all in the mind

Status: offline 		Well, this thread is a little silly in all the goings on and I hesitate to get into it but...

Two stroke supercharging could work. It might not turn out to be feasible, but it definitely could work. Back when Hitler commanded Ferdinand Porsche to build the "Peoples car", (the Volkswagen), he was working on a four cylinder two stroke engine that had two cylinders supercharging the other two. He never got to finish developing it because Hitler was pressuring him to get the car on the road. You won't see much more two stroke development from the big concerns now because of fuel efficiency and smog problems today. I believe there are two stroke turbocharged diesel engines made, but I don't feel like researching it right now.

Anyway, just my dos centavos...

Status: offline 		Yes detroit Diesel with valves, designed specifically to use forced induction............nothing like our purely piston ported rc engines

edit......I am not saying I believe you cant make a turbocharged two-stroke, I am sure there are many marine examples, but I am saying adding one to an otherwise normal piston ported 2-stroke like the ones being discussed here is not going to give worthwhile gains, even if properly engineered

edit two... Sorry Now I am getting ridiculous, I'm just re - stating my position over and over which is adding nothing to this discussion so I'll not bother this thread again.
Good luck Tim

Status: offline 		Crusty is that an opinion or is that experience. If a change in altitude can change performance I believe a turbo could have the same effect. I am confident you are wrong.

May the forced be with you

So anyway, Have you blowed one up yet? Youll never know how better it is until you go beyond its intended duty cycle. How about some nitrious. It would be a compliment to your turbo. Keep up the good work.

ffs, there is a huge body of evidence to back up my wrong theory, what you got to back yours up Rupert?, apart from some guy who soldered up a turbo and says it gives double power...get real

edit...oh and please try and understand (it seems to be escaping some people here) the thread is about turbo-charging a conventional piston ported two stroke
and as for the snide little dig, no its not from experiance its from lots of reading and understanding...I also know that the moon has a dark-side...also not from experiance
