I remember the thread too, just can't remember who it was...

[cosmicsclassic]

hi jeff, thanks for the welcome

Howdy, Cosmic... Sorry, I'm only good at one thing at a time, and was hunting for that thread Jeff and I were discussing.

As Jeff said, welcome to the asylum.

hi to you too jamie. tryin to learn to navagate this place

Sorry it took so long... busy evening.

This isn't the thread of the problems, it's the one of him selling it, but now you have the name to search for...

GOOD LUCK WITH THAT!!! The place is nuts... 50,000+members, often over 1,000 on-line at any time... and that makes it the PERFECT place to be!

Congrats on having an avatar for your first post... but that doesn't get you off the hook for the golden rule...

BIKE PICS ASAP!!!

hi all... if the hypercharger worked out for your uncle and other members here i think thats great...

shoot im still tuning my okie smoke intake but thats only cause im a meticulous savant

im going to hit the dyno this friday

kenny

[jeffs99vulcan]

Finally found the guy that had all the problems Kenny, I don't know if it's the same guy you were thinking of, but endl98 coudl never get it tuned and ended up selling it...

[Mercury]

im sure thats one of um

kenny

Well, as I mentioned to Jeff in a PM, I think people forget that with the hypercharger, it's gonna be nearly impossible to set it up at low speed/WOT and get it to not run rich on a carbuerated bike, or to have it run lean at speed. it'll almost have to do one or the other, given the set-up.

The amount of air being rammed into the intake at 80 mph is gonna be vastly different than it will be at 0 mph, after all. So it only stands to reason that a person will have to choose the conditions they want the thing to work well under, and go from there. Either that, or get a Fi bike that'll automatically compensate for the change in air input, or go with a different intake. *shrug*

I have to agree with that, though i will also bet the peak power that the hyper charger can give will be more then my intake, but mine will be more consistent

You know, you're right, and that's part of what was SO cool about the 70's beasts...

I remember like it was yesterday a Pontiac GTO I saw at the gas station that had more blower, belts and pulleys sticking up out of the hood than engine under it, and it struggled to idle... you know the chug... chugchug... chug... ka-chug... right before he TROMPS in it!

Man... that was cool. But same thing... they don't run the same at ALL speeds. I'm not so sure there's anything wrong with that...

On a dyno, yeah. On the road? Maybe not.

Also, there are ways to get around the ram air effect, or to eliminate it altogether. A simple baffle/deflector in front of the intake, or even venting the rear of the charger, for instance.

Again, it all depends on what you're after.

P.S. Anybody else remember the old '60s stock cars, with the ram air hoods, or even ducts where a pair of headlights were supposed to be? Betcha those things ran a bunch better on the track than they ever did hooked up to a dyno.

i would think venting the rear of the charger will be like blowing across a straw stuck in fruit juice, and you actually suck air OUT of the carb... hehe

theres some engineers and scientiests that sit there and study the air flow and many different "priciples" i cant even pronounce...

i like my setup and im sure others with the flappers (hypercharger) like theirs...

once i get mine tuned right, lets race um

im still working on mine, i cant get over 95 and i know i used to be able to

hah

Make the vents too big and that's exactly what'll happen. It's called the venturi effect.

The idea is to get the intake to a stable positive pressure, without going into an over-pressure situation. In other words, allow the carb to get as much air as it can use, at any speed, without leaning things out too much.

Um... I'm kind'a sort'a one'a those guys. I've been a mechanical draftsman/designer for more than 20 years.

Then all is as it should be... except for Jeff's ticking.

Did I mention that I also did a stint as a cop?

Heh... you'd better keep tuning then, 'cause my stock bike will do better than that, easy.

Anyone thought to add a little Nitro ?

Nah, not yet...

I still haven't quite worked out how to hook up a belt-driven blower yet.

If i can figure out how to fix one up like the one in the car Mad Max and The Road Warrior, then I'll think about nitro.

THAT'S what I'm talking about!!! Did you miss my post on the GTO up there?!

That's my all time favorite muscle car look (and sound)... the big, three-port blower poking up outta the hood... probably why I like the hypercharger and it's flaps...

And what's with that anyway??? It has flaps, why can't it control overpressure?

Yep, missed the GTO post. It wasn't there for me the first time through.
Computer/servers are up to their usual tricks I guess.

It probably can, if the butterflies are adjusted properly.

Then again, they're vacuum actuated, and that may be a stumbling block too.

One way or the other, I doubt they need to be wide-open at full throttle, while the bike's in motion.

Right now, I'm thinking some sort of pressure relief valve(s) in the rear of the intake body is probably the best and simplest solution.

I think it's just an overlap... if I post while you are typing, mine will show up already there before yours, and if you're like me, you don't look up past the ones you just wrote (thinking of course, that there won't be any there!)

I could kinda tell you missed it, you said pretty much what I said about the 60's-70's muschle cars! Loved that deep, uneven idle...

I have to imagine they must be, I went through the instructions (although a long time ago) and I certainly don't remember any electrics or electronics!
