TZ, is your Ariel Arrow still languishing under the bench?

........ yes same place as the turbocharged 100cc 4T CVT project, and the turbo 70cc 2T

Nah; you can't cast decent disc recesses like that anyway; they'll always need some final processing.
I suppose the simplest approach would be to cast those cases 'full' and then dip in a cutter blade.

That port layout looks a lot like side ports on a Mazda Wankel.

Lots of photos of the Alpha (and the disc valved Centuri twin) here: http://www.villiers.info/Alpha/

Here is the race test on the Alpha twin

I'm looking through the book now!

Nitro just made my hobby alot more exciting!

you may find something useful here http://www.modelairplanenews.com/wha...r-your-engine/


is this the stuff your using ? https://www.vpracingfuels.com/produc...y/rc-fuel/car/

Thanks!
I'm using this stuff:
https://www.hpiracing.co.uk/piw.php?partNo=OP1006
for no other reason than that's the only fuel available locally.
Ideally I would just buy the nitro/methanol/oil separately and blend to my liking, but as nitromethane in higher concentration than 30% by weight(also has to contain at least 10% oil) is illegal to own here in Norway(they think you'll be making bombs) it's difficult to get ahold of.

Have you tried a chemist or a Dry cleaners.

when can get it here.

Vets can be a source of Nitros Oxide refills as well when you decide to have a play with that.

I thought it was the Swedes that were over run with Terrorists now.

Haha! Sorry, guess I shouldn't laugh.
It's not that easy.
Asking for it at the dry cleaner is considered suspicious activity and will be reported, ordering online too.
I'm probably already "on the list" for showing so much interest in the stuff and other chemicals deemed too dangerous for regular people.
1984.
I think it's just as restricted in Sweden now too, otherwise I would just buy it there as I live on the border.
It's not that I care about the legality of it, but others do and that makes it difficult.

You could always approach the relevant authorities and explain what you want to do as thats something terrorist i guess don't normally do.
Failing that take your complete bike over the border and fill it up there.
Pretty sure I watched some euro-doco on a drag racing (rail)Norwegian team they seemed to be able to get the nitro
The only time i have heard of something similar in NZ was when the guy was making very large rockets and was getting too much interest from Middle easten Businessmen)

Actually no.
It´s not illegal, you just need a couple of hours of study and make a test to get certified to buy it here in Sweden.
It´s not illegal to own in Sweden, just need that certificate to buy it.

If you want to test a lower percentage nitro first, blend in more methanol.

But, buy 2nd hand from a local dragracer if you know anyone that is

[TZ350]

Fuel..... I love all sorts of liquid and gaseous internal combustion go fast joy.

I would just love it, if fuel for Buckets was totally open. Sure, the white coats can still have their boring reliable 96 octane store brought pump fuel, but let's let the real chemists shine.

Good to know. In Norway it's practically impossible to get certified for "hobby use".

tour de france rules then? Only Without the lycra.

FYI: That ban is EU-wide.

REGULATION (EU) No 98/2013 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

of 15 January 2013

on the marketing and use of explosives precursors


Hydrogen peroxide, nitromethane and nitric acid are widely used for legitimate purposes by members of the general public. It should therefore be possible for Member States to provide for access to those substances within a given range of concentrations by applying a registration system under this Regulation rather than a licensing system.

And "chemical supercharging" just sounds cool!

Model boat racers in Europe seem to be able to get nitro, but it's expensive compared to the US. Here, top fuel drag racers run close to 100% nitro. Below is a summary of a series of tests we did on a 26 cc spark ignition industrial engine setup to run gasoline. The open transfer, piston port engine was modified in standard ways for racing. Everything was the same as for gasoline except we changed the needle settings to give best power with the various fuels.

The red text was left out of the published version where we were only talking about different gasolines. The additional tests with methanol and nitromethane were to address whether we needed to use Digitron or similar tests to prevent fuel cheating. These tests prove that fuel alone isn't the answer for more power. You would need to change the combustion chamber volume for higher compression, and the tuned pipe for lower exhaust temperature. In addition, variable ignition timing would help.

Very interesting, thanks!
Looking forward to seeing if my results will be any different.
