ESE's works engine tuner

[SS90]

Thanks Gatch for your interest in the posts. Team ESE are well aware that there has been a whole generation of fast buckets before, but that was then and this is now and we are enjoying finding out how to do it too. With 21 RWHP for my 125 and 22.5 for Chambers 100, I think we are getting there. We know it takes more than just hp to make a successful bucket and I think we are getting to grips with that too.

Yes I think its important to share the info around and be able to backup ones claims, I got the full bullshit treatment today by someone who should have known better, I don't think we will be seeing any confirmation of SS's claims any time soon, but you get that with the talkers that just want to be noticed.

Whatever, those old supercharged Kriedlers, and other racing 50's, great bikes, just love em..... http://forums.autosport.com/lofivers...98711-700.html

Just put me on you ignore list Teezee, if you can't believe that everything you are only just learning now has been tried decades before you are very very mistaken.

Hows the Plenum.... still in the wardrobe with your Karate suit and acoustic guitar?

I assure you faster buckets have been built than yours 20 years ago.

Yes, we know that's true, but its a pretty fair bet that its not one of yours........

Now that's just plain childish...........

P.S. SS90 revenge red rep is immature too...........
OK, so you haven't learn't to contribute in a positive way yet, back to the naughty corner you go...............done like a dogs dinner...

While investigating small turbos a while back I found that Yanmar made a small diesel generator with a turbo. Can't remember the details and i ended up with the little IHI off a Suzuki Cappuccino which is not too much bigger I think.
Holden supercharged 3.8L v6s used a belt driven centrifugal supercharger. The compressor looks like a turbo compressor and the "gears" to increase the shaft speed have no teeth but rely on the properties of the oil to provide traction. As it gets jammed between the rotors it becomes grippy. Can't remember the correct technical term for the property.

Elastohydrodynamic.

I remember reading about a "gearless gearbox" set up for mountain bikers. Essentially 2 ball bearings with a pin through the centers of them, whos angle can be altered to effectively change the "gear ratio" across them. This assembly used something similar to provide grip between the otherwise smooth bearing surfaces. If it is the same stuff, it is known simply enough as traction fluid.

Another clever engine, the Honda 4 cylinder V8..........

Designed to increase the valve area by getting around the rules limiting race engines to 4 cylinders, the engineers must have been bucket racers in a former life.

Why pollute this thread with that pile of poo? Typical Honda, throw a bunch of money at a weak technology (4 strokes) to try & redress the balance. Not even with the ridiculously talented Freddie Spencer could it beat the 2 strokes.

Honda went away to sulk & conceded defeat while ironically rushing through a 2 stroke that spanked the world. They then decided that if they couldn't beat the 2 strokes in the 500 class they would have to cheat. & the best cheat is to pressure the rule makers to allow them double the capacity. Both in GP & MX.

Fuck em I say.

I know how you feel........ but it is a good example of thinking outside the box... a very Bucket Racer thing to do.

Found this at work this morning, the centrifugal air pump impeller (also known as "radial") that TeeZee was talking about.

This one was spun by a very large electric motor for an air bubbling system at a water treatment plant, (high flow and relatively low pressure, makes it a blower).

It could just as easily have been spun by a Spitfire aircraft engine and used as a supercharger, (relatively low flow and high pressure, makes it a compressor).

Hadn't thought about it much before, but one of these would then become a turbocharger if it was spun by an exhaust gas turbine..........

This type of impellor could be used as a "Blower" or "Compressor" or even as a "Turbochargers" compressor, depending on how its setup.

Its having the exhaust gas turbine on the driving end to spin it, that defines a centrifugal air pump as a turbocharger, not the fact it has a centrifugal impeller.

Well there it is.......... Thanks Bucket

One of Chambers projects, a supercharger for his flathead V8, he is a hot rodder from way back.

A Roots type blower converted for use as a "Kompressor". If we had one small enough we could try supercharging a 2-stroke with it.

Must talk to Speedpro about a supercharger, he has one or two, it would be interesting to see if we could supercharge a 2-stroke with a Roots style Kompressor or a small Turbocharger ourselves.......

why is Thomas Laughing


and whats this guy got to say about it all

Seeing that Wade blower reminds me of a visit to Gasworks Park in Seattle. There was a "HUGE" roots type blower there. It was about 10' high. You could climb on it up this ladder and stand on it. I figure if my mates blower on his car is a 14/71 then this thing must have been about a 100,000/71. It wasn't high helix though

[Henk]

Uninformed question time. Will a blower on a two stroke make the chamber largely redundant?

What do the numbers 14/71 refer to ? You see it all the time, 6/71, 8/71 etc.

What the deuce does it mean !!

something to do with the air fow bigger number larger air flow

was told ?? dont know how right it was
but 6/71 was for a 6ltr engine
and 8/71 8ltr engine
so a 14/71 was for a 14ltr truck engine ?
