What Type Of Fuel Did They Use In The Early 90's Atcc?

[Chris32]

Can't find this info anywhere, does anyone know for sure what type of fuel they ran in the R32 GTR era?

Cheers

Shell. If I remember correctly they used the unleaded sold in Darwin as it was more stable at high temperatures. Not sure of the octane rating.

[Chris32]

Interesting, surely they must have run over 91 or 95 Octane given the boost they were pumping through some of the Sierra's etc?

[djr81]

Don't remember. Dick Johnson was all over it as he had the Shell sponsorship at that time. If you dig around the Sierra histories there will be some info in there.

You couldn't buy 98 octane in 92 I don't think.

Can you say 6.5-7.0:1 compression for the lowly fuel quality and boost they used to run All I recall was it was a control Shell fuel. Have a look back to 87 and see the hoo-hah over fuel and you may find a bit more info on what they were meant to be running. The Texaco fuel was proven to be ok but you may find out what OK was after being talked about being illegal

Don't kid yourselves. The fastest ones used rocket fuel. No category of racing has an absolutely level playing field.

Liquid oxygen with Kero?

... toluene

... toluene

Cool.

I thought toluene was an additive used in Jet fuel?

[PN-Mad]

Shell 100 octane apparently.

That may be what the sticker on the outside of the can said...

Not sure why people are so willing to perpetuate myths about fuel....

[Roy]

Yeh, they were rather heavily policed in teh Grp A days. Teams may have got creative with fake fuel cells and rocket fuel etc....but it was very stupid to just top it up with rocket furl and go! Remebering how primitive ECUs were then to change to a rocket fuel was something you were not going to be able to change mid race with a better fuel used at a stop etc only to fill back up with compliant fuel for the final leg etc

[XRATED]

There were. Many ways that 'user' adjustments were made to fuel, ignition trim and boost levels.

I wouldn't think that it's outside the realms of possibilities...
