Just wondered what percentage use which fuel.....

I'd recommend Nitrous Formula; its not always easy to find, but its worth looking for. Simon

optimax + booster, that is just plain greedy!!

rfowler

where can you get the Booster from

S.B.

What about the bp ultimate users?

Fat Boy

They won't use it for long, not if they've got a knocklink fitted anyway....

How about a poll for which booster? NF Race gets my vote, and I would lay odds that it is the booster of choice amongst people who know what they are doing

NF Race Formula for me and it is now readily available from Roger Clark Motorsport.

Im not sure that 99% of people on here could say 1 booster is better than another. It makes me laugh when people say, "I use this, its much better than that" To quantify such a statement would require months of research, and a good dose of dyno testing. Ok, one might cause a small decrease in knock activity, but what residues do they leave etc?

I use Opti and Millers.

My MY02 Sti is a UK car, but it was set up by TSL for the latter choice. (Millers)

mapped for optimax and a full tin of proboost, but i am running 1.5 of boost

Not noticed any huge difference on the knocklink running with or without a bottle of octane plus in the tank. Minimal activity around the bottom of the LEDs bottom or next to bottom on full throttle.

Sti V running lagged BPM DP, magnex resonator mid-section, standard STi backbox, standard subaru paper air filter. Now my 1.5 bar over boost is cured it peaks at 1.35bar. The overboost, I also had a scoobysport BB on at the time, did result in knocklink activity -especially full boost then lift off at high-ish revs - all the lights - NOT GOOD!

Now only use the Octane+ on long trips or for enthusiastic driving

One thing I have noticed is that the bottom knocklink light goes momentarily on sometimes when changing lanes or over bumps on the motorway - is this most likely due to the oil sloshing around in the sump? Anyone else seen this?

I dont use booster at all on my Type R no need to unless the KL tells me different.I only light up the first green on WOT with plain optimax so thats the way it will be staying until it tells me different
