i hear it's 100 ron or more and its about £1.10 a litre

whitch is cheaper than optimax on the motorway services

im thinking of geting my tank filled up and some jerry cans with avgas if i can actualy buy it

and then go to get the omex 600 mapped for avgas with water injection and then i can swap the maps over on my laptop in a matter of minuites

 

yes but you dont want to...

its burns very slowly (not good fgor high rpm) and is leathal to catalytic converters!

oh and it the feds catch you its


Alex

 

humm so why is it illigal?

 

Because of it`s huge lead content....

 

its not taxed for road use...

its like red diesel...

Alex

 

tried it in my old peugeot 205 (mate has a helicopter runs on it) made the 205 feel more responsive and pull harder to about 4500 rpm but it didnt want to rev much higher than that and it used to rev to 8000, learnt my lesson. works ok in the chopper though.

 

oh forgot to mention used on private roads only when running this fuel

 

real tears of laughter

 

i was thinking about using it for santa pod and track days at donnington park

i thought it would be ok for an engine that has been mapped to use it

so whats the difference between race fuel and avgas at the same octain then?

 

lots...

avgas is design for aircraft, as you migh guess!

Aircraft engines are very low output for the size... say 150bhp from 5 litre. Its much more important the engine keeps going, rather than performs well! So they are lazy low revving engines.

In terms of the fuel, it has very high lead content (again helps with valve lubrication and relaibility). This gives it a very high octane rating. But... and heres the big difference, it burns slowly. Hence it not likily low revs.

Basically for a high performace engine, you want a high octane rating, which reduces the fuels desire to detonate, while retaining a decent flame propergation speed (so it will burn quickly enough at high engine speeds).

fook me your a smart puppy
fair play though,,,,,,, not many share there knowlege at times

 

cool ik keep on watching volcano on itv2 and forget about buying fuel for airoplaines

and make the asumption that avgas is just 5 star petrol

 

Only the avgas running ones Alex, as you are prob aware.

Performance orientated aircraft use avtur. No good for RS's unfortunately, but if you have a diseasel daily runner avtur is excellent. 50-50 mix of the two. Doubles the fuel consumption on top of the normal diseasel output (only 50% needed to fill tank) and does not have any long term damage.
Cheap as chips.

 

Piston engine aircraft use Avgas, Jet engine/turbo props etc use Avtur.


Aircraft piston engines are designed for torque hence they don't need to rev fast. They may have low bhp figure, but you'll probably find they have high torque outputs for the size

 

*looks up*

Any ideas where I could get some of that from mate? I'd like to have a butchers for .. err. My Jet-engined.... something.

Which I quite clearly have.

 

if u go to small air fields you can get it. I ran it in my honda for a top speed day once (also put a bottle of octane booster to every jerry can ) and the fooken thing just wouldnt rev properly.

 

Exactly mate: piston = slower & economical, turbojet/ turboprop = performance & not very economical in comparison.

As for availability Steve200+ : you need to find yourself a friendly aircraft technician local to you who *could* source some avtur now & again without raising too much suspicion from other work people.

 

You can go to a small airport and buy it quite easily, it has a bigger lead content compared to normal pump fuel though, so I wouldn't recommend it for a car.

As for "it's not good for high RPM", I disagree. It's very popular amongst motocrosser's ( 2 stroke ) which rev far higher than normal or even race going car's. Race fuel also burn's slower too!

 

ill get myself down to ards then
