ESE's works engine tuner

TeeZee has already talked about sleeves, use Thread Tools and View Images to see them.

Anyone who thinks they can win races against the current crop of 20-23 hp FXRs with a low 20's hp 2-stroke is likely to be dissapointed.

who had these 75 hp f3 bikes? but agree 22-24 hp 2 stroke with a good bike set up and rider is all it needs to win gp's

Put the same people on a 2 stroke and the same result me thinks.

Best of current crop is faster than the old dogs for sure. Young hard charging kids that can peddle a 600 fast as well as a bucket are the ones to watch out for. Us old dogs are getting put out to pasture.

I apologise for thread dredging here but it's amusing what is said on the internet then proven wrong. Then it's followed by some old bloke from down sound playing a very small violin only to come second in the 2013 Tokoroa GP

I have tried to win races against the current crop of 20-23 hp FXR's and was dissapointed ....

Brock .... good thinking, deserved a medal.

It was clever, i liked the Allan Moffit in your face rule flouting, it cost him points, but it got the rules changed. From memory he also did the same with dry sumps till they made them legal as well.

Round four - Sandown; Allan won the race on Sunday but was eventually disqualified. Both Moffat Ford Dealer cars and most of the other Falcon teams were using illegal roller rockers.

Unsure, but the plenum at 2.5L is 10 times the size of the engine and with a fan inside the plenum blowing plenum air through the radiator I expect that a lot of air will get several passes through the radiator (heat absorber) before being inducted by the engine.

Anyway, whatever happens the air will be cooler and denser than it would have been.

Yes but
30HP/85kg=.353kg/hp
34hp/95kg=.357kg/hp

If you were to pursue this path wouldn't a long thin intake give you a greater surface area for potential cooling like a RSW intake for instance.

30HP/85kg=.353kg/hp
34hp/95kg=.357kg/hp

I see your point, luckily I have been on a diet.

How many passes did you say?

The NASCAR guys would have a fire extinguisher filled with nitros oxide, they would release the extinguisher contents about the radiator support panel at a specified time when qualifying, this would be ingested through the appropriately jetted carburetor and wellar, pole position here we come


Some pro stock drag race guys had fitted nitros systems within the dry sump swirl pot, nitro lines would be inserted within the oil lines of the dry sump system to conceal them, once at the valley cover / under the intake manifold seperater plumbing and nozzles were hidden to feed each intake runner, this all came to the light when a system exploded, most likely a oil Vs pressure problem, shame these ideas men didn't understand how a diesel works

Thats just mean, but it would also mean three potential heatings on its trip past the Ballvalve

[TZ350]

... three potential trips past the Ball valve ...

I hadn't thought of that .... I must make a video clip of it.

....the Entrants Association imposed a $5000 fine on Brock for a moral infringement of the rules.

In my book there is no such animal as moral infringement. There are good readers and there are badly written rulebooks. Either something is laid down in writing, or it isn't.
Whenever someone mentions"'the intention of the rules" you can be sure that the rules are rubbish.

Frits if i may, how does one go about designing a blance shaft and settling on the starting point for the weight?
Is there a simple formula or rule of thumb?

You may, Husa. The picture below may give a first impression, and you'll find the whole story here: http://www.tonyfoale.com/Articles/EngineBalance/EngineBalance.pdf

OK I looked at some numbers.

It looks like 600 kJ is required and I can get that from 2 kg of ice or two and a bit liters of ice water.

It looks possible and the result depends on the effectiveness of the radiator and fan inside the plenum.

2kg of ice, that is not such a big fridge, the idea might be possible.

Maybe you should try it on a 20hp 80...

I added your quote not to say you were wrong, rather to point out you were right... I just forgot to write that part

20 years and l get something right for once must be a record
