We've started making a pre-production batch of 500 liters of octane booster for our own cars and for sale to local car and bike street racers.
The booster is based on BTX chemicals and additives to give an octane of 117 to 118 without the use of TEL (tetraethyl lead), a bit like the old 1990s formula 1 fuel. It's a blend of BTX chemicals with a top lubricant and an oxygenate. We're still experimenting with the blend with our tame chemist / petroleum engineer (code named Chemical Barbie) who has access to petrochem labs.
We're looking at some other non TEL exotics to push the blend to 125 to 130 octane.
Avgas is hard to buy here and racing fuels are damn expensive , this blend gives us the benefit of avgas at 40% less cost than buying avgas when available.
Blended 25% booster to 75% of normal tank of local 94 octane fuel it provides just over 100 octane.
Biggest difference is in smoothness and drivability.
We're using my 530 , Taffy's M5 and various office staff motor bikes as test mules.
Last night in the 530 i was able to go full throttle in 5th gear at 1,200 rpm with no audible detonation so it's working (normally the 530 will detonate in 3rd gear at part throttle at low rpm, the fuel here is THAT bad).
Taffy tried it briefly in his M5 this morning and has a 10 degree drop in oil temp (normally close to 99 to 100 deg C , now 89 to 90). The bike riders have also noticed that their bike engine crank cases are running cooler when touched by hand. I can only think this is because of less pre-ignition events ?
It won't make any difference to power output until the cars are re-mapped but throttle crispness, drivability and smoothness at high rpm is there already.
I've snuck a trace of Castrol R into the blend for that vintage racing smell
