Keep in mind, that there is more to this than blowing air into the carb. To be a fair test, you need to have fuel enrichment tied to boost.

that is what rejetting the carb (or new carb) would do. that was never forgotten. was actually one of the first things.

A turbo's boost is variable, so goes the fuel curve. What happens to the fat jetting when the turbo boost is low? Deciphering your excellent explanation of the bitchen fast go-ped, I assume your cousin is running a Zenoah/Walbro motor. A motor we heli people are very familiar with how sensitive the needles are, so how exactly is this accomplished? Another flaw in your story, is the carb spacer thing? If the carb is draw through as you state, air would blow out the carb, not in. Pictures would be nice. Roamer 'ole bud, I would gladly say, "yup I was wrong". I still believe the four stroke supercharged is the path to the promissed land. At least that is the direction I'm headed.

Unbalanced, I read the whole deal, and there could be some valid points there, except just like this thread, when the poster gets asked the REAL questions, he backs right up and tries to re-direct everyone's attention with fluff and BS. I think a very small ported two stroke could show some gains, because the motor is turning 40 grand, making the loss through the exhaust not so detrimental. Our gassers turn at 10-11-12 thou, glow motors at 15. Also, I want to know what happens to the oil from the fuel when it hits turbo blades running at 50-100,000 rpm.

I've searched the entire internet for your cousin. Being your cousin, and knowing what color his ATF is, I would think you would at least know his name. Should we read every German magazine printed? Or can you direct us to a specific issue of a specific title? Call your cousin, find out, I'll PayPal you the $ for the call. Inquiring minds want to know.

i serious dought you want to know. you just want to be right and contradict me. lol

the carb spacing doesn't ruin anything. it would be more likely to blow out the carb is it were closer. and it has to get in there somehow.

i have a works datsun GT-1 car. it's a carb. turbo. you have no idea what you are talking 'bout. lol but that's fine.

there is no point in explaining anything to you.

i haven't avoided anything. your right... i say i'll tell you later 'cause my fooking grandad is dying you crazy arsehole. no shiite i'm going to be there instead of gripping with you.

i have photos of the GT that i might be able to scan. i don't have a scanner though.

you guys haven't actually asked good questions. and any answer you don't want to believe. so do you really think there's a point...... nope.

i gave you his name. this goes back to the thought of i don't think you can read, or you are just not capeable of it.

colour his ATF is.... what in gods name are you talking 'bout. you say a lot of just nothing. and most of your nothing is taken completely out of context.

hahahahaha you offering to give me money. that is funny. thanks for the laugh, i needed that.

-I want to know what happens to the oil from the fuel when it hits turbo blades running at 50-100,000 rpm.

it's fine. what happens to the oil in the fuel on your glow engine when your spinning it a 17,000.

and now you are backing down from your high ground. lol

"I think a very small ported two stroke could show some gains, because the motor is turning 40 grand, making the loss through the exhaust not so detrimental."

BUT WAIT!! YOU SAID IT WAS NOT POSSIBLE!!! hahahahahaha.

if the engines can make efficient power at 14K-16K and keep sucking that air in. they wouldn't have any problem with forced induction. all it would do is lower the potential peak power. just like any other engine.

one more bit. i haven't re-directed anyone mate. i keep saying the same thing, and you are trying to find every single pheasable angle to make it all wrong, so that your thought can be right.

i'm not the one who designed it. i didn't build it. i've used them, and i know they work. that's all. if you can't find it, you're not looking hard enough, or perhaps you're looking in the wrong place. don't know what to tell you..... and i don't really care.

good day to you.

yep, they work... those are neat. problem is... a super charger wouldn't work too well on a heli. kinda have a fan in the way... lol

i hadn't really thought too hard into how to mount the super charger. may be easier to just put a turbo on. i'll try it when i'm not feeling so lazy.

what did you have problems with?

Heres a pic of it done Still doesnt work!!!!!


We even tried makeing a bigger impeller for it! Still doesnt work!! To creat enough Boost it would have to be geared to spin alot faster than it does!! then to Oring belt would just slip!!

Just Fly It!!!

had an idea....considering that heli engines already have cooling fans for the head, it might be possible to tighten clearences around the shroud until the pressure inside the shroud rises. part of it goes to the cooling fins, another part is rammed into the intakes. either that, or after going past and cooling the cylinder, is directly and totally rammed into an intake...

please feel free to prove me wrong...flame suit on.

cwm,

When you saw doesn't work, do you mean that it doesn't help or that it doesn't run at all?
