ESE's works engine tuner

[cotswold]

[QUOTE=TZ350;1130878503]Team ESE have been busy working on developing our RG50's.

Currently our RG's are about 13-14 rwhp

13-14 rwhp is plenty, if you get 17 I will have to get rid of my Honda iron cylinder and spend some money on an aluminium (unobtainium) cylinder out of Europe, I'll let you explain that to mrs. Cotswold

welded some ears on this manifold tonight. as it sits the outer wall of the aux tunell will join the manifold at a larger angle than i would like. thought about using a 6mm spacer between the manifold and cylinder exit ,as this would let the aux tunell outer wall enter the main tunell more gradual but i think it might throw my pipe brackets way off and the front tire dam near rubbed the pipe as it was. maybe ill have a look tomorow. since the spacer would be before the beginning of the pipe would it affect how the pipe works ? i havent even got around the putting any of this in engmod yet so maybe the spacer might help. i was just thinking maybe i could shorten the manifold and pipe flange that goes over the manifold to compensate for the spacer

So if its not been checked in EngMod how do you know that the CR500 spigot ID isn't miles too big ?

[peewee]

well it may be slightly big but i was hoping its close enough. other wise i have to get a new pipe. im already going broke because this . old cylinder on this bottom end was 3mm bigger piston and called for nearly 48mm but it didnt have any where near the amount of blowdown area this one will have. cr5 is 50mm so i should be in the ballpark. ill consult with engmod and decide from there

yeah that's right. Said he had a 750 triple he was going to restore but never saw that. Bit of a character but seemed a good guy.

Ah, something possibly relevant to this thread...The last thing Matt built in ChCh before going home to Wgtn where you met him, was an H2 750 kawasaki.
I remember him saying it was the same bore and stroke as the 250 Bultaco singles and he'd got the port timings and pipe specs for them...
I don't think he actually ran it before moving North so i never saw it run.

In the absence of anything like Engmod, that still strikes me as quite a sensible start to development.

Frits, if you look up the word "dodge' in the dictionary the definition is "to avoid".

You're telling me now, Larry...

My grandma used to say: "If you can't afford a Dodge, dodge a Ford".
FOS over. Saw the V8 Moto Guzzi, but it was out of action, so no sound. Saw a Trabant though, but it was also stationary.

Too bad you could not make it to the Sachsenring, Ken. I saw, heard and smelled the Moto Guzzi V8 in anger. It sounded almost like a two-stroke.
Saw a fleet of Trabants that were far from stationary; watched two Trabant races together with my mate Frank Ziprian, also known as world's best Trabant tuner (changing 26 HP into 80+ HP).

Is Ryger taking water injection to a whole new level? Super clean piston and exhaust (steam clean). Now the crank case is sealed off from the rod and crankshaft allsorts can be done under the piston, how does the piston not melt, how does detonation not ruin the piston? How is higher pressure made in the crank case (under piston) to overcome lack of blowdown time, how come when the Kart does 113 laps endurance the power has to be dropped off, perhaps lack of water storage for the long trip? I think under piston water injection might play some part in this engines performance. Perhaps?

I remember someone advocating switching to the metric system in a class long (very!!) ago, in a contemptuous tone, saying that, "Our system has the inch based on the width of old King Harry's thumb, the foot based on Harry's foot, and so on; how unscientific!! The metric system is based on the wavelength of particular light spectra in a vacuum; entirely scientific." Yes, said I, but of what practical use is that? The width of your thumb, your foot, your pace, etc., are, as any Boy Scout (which I was at the time) learns, immediately USEFUL!! King Harry was right.

Frits, I can top your Dodge as an appropriately named car, for a little while in my youth I was driving and maintaining a Plymouth . . . a Plymouth Fury . . . .

OTOH, some years later I owned a '73 Dodge Swinger (a sort of sporty Dart, Dodge's econo car) with a built Slant Six. Not only reliable and economical, but versatile; these Dodges had torsion-bar front suspensions, and if desired you could get under and quickly adjust the front-end ride height up or down. I completed this adjustability with a set of air-shocks in back (and had the battery mounted in the truck for more traction). I was occasionally called on to serve as a chase-car driver for a couple of friends who were hang-glider pilots. With both ends of my Swinger adjusted for max ground clearance, and snow/mud tires installed, I amazed all the other chase drivers with their high-dollar four-wheel-drive rigs, who could hardly believe that a mere CAR, a 2WD coupe, had made it up the mountain over the steep, deeply-rutted trail, carrying two hanggliders on my home-welded rack.

No company manufacturing motor vehicles was better at finding good names for their products than Hodaka. You had to love a "Road Toad," a "Wombat,' or if racing, a "Combat Wombat." Sounds like bucket material to me.

years ago i had a chrysler car with over 300K miles but back then they were using mitsubishi engines

In defense of US technology, there are still some exceptional things being done using our antiquarian systems of measurement and tools.NASCAR takes the cake in the spirit of bucketeering.Take a POS sedan with a motor designed in the 40s and get 14 bar bmep(granted they cost a bit). We also do good with weapon delivery systems.I do have to apologize for Harley and all the other American "Iron"

RE:Ryger...to what effect would ceramic bearings and possibly rings have on an engine's ability to rev?Also as the oil doesn' need to burn we could use some exotics in the crankcase.

Emulsified fuel / water? Ceramics would be useful for this.
Partially a steam engine?

Flux capacitor?

Only reason I ask about the CR500 spigot is that I am doing a KTM250 for roadracing in a kart and its making around 75crank Hp.
That will have a 42mm header dia = around 75% of the Ex effective total area - 50mm is absolutely enormous for any 250 cylinder.

[peewee]

wob this engine is 510cc 89x82. im hoping the cr5 spigot will be close enough to work fine but ill get around to loading it in engmod and figure it out from there

made a mold of the transfers today. i think what im going to do is run a bead or two on the outside of the cylinder and then use devcon on the inside wall so i can get a nice big radius through the duct. the plate attached to the cylinder bottom was nothing more than a half ass heat sink in hopes the gasket surface wouldnt pull down. one side stayed pretty flat. the other side sunk about .16mm (which is good enough for me) for you metric folks. i guess it should be more like the blue line

[peewee]

anybody used one of these 3in1 untis ? really considering one for cutting head chambers, making intake manifolds and such. oh ya i got thinking afterwards about that cylinder plate. maybe i better put a tack weld in the center to keep the gasket surface from moving any further. why dont i ever think of this shit until later on
