Octane Booster @ Trackday

[noone]

Taking the bnr32 out for its first track day tomorrow at hidden valley and wondering if its worth putting in some octane booster, car is running a remapped ecu (done in Japan as best we can tell by zeni tani) has been checked out by workshop here and all is good, new car and not sure if they had to retune or anything to allow for less octane in fuel . Only good available fuel available in town is BP Ultimate 98RON. Have used NOS brand octane booster before when travelling outside of town and forced to use PULP

PULP 95 +street octane booster 3 = 98 (same as BP ultimate) no drama's with car at all.

Given Jap fuel is 100RON (I believe anyway) and all I couldn't help but wonder if some octane booster even in BP ultimate might be worthwhile.

Two options are street tune NOS stuff +3 octane numbers = 101

NOS race stuff +6 octane numbers = 104

if mixed with BP ultimate.

Damn hot here in Darwin and anything to reduce possible knock is a good idea, Just wondering if anyone has any input? will of course reset CPU if using this blended fuel to allow ecu to advance timing happily.

might as well, it's cheap insurance. if you don't bother resetting the ECU then the ECU will still be using the conservative map it learnt for 98RON. reset it after the track day so any learning for 98+octane boost is trashed

[noone]

Yeah good point about reseting it after too, Hadn't planned that far ahead yet.

FYI - Adding an octane booster with a rating of +3 points to 95RON fuel doesn't equate to 98RON.

** 1 octane points = .1 octane number **

eg. If you add +6 octane points to 98RON fuel = 98.6RON at best

My Bad,Yeh sorry wrong terminology used by me,

Packet for NOS stuff says 3 or 6 Full octane numbers, 30 or 60 points so numbers should still add up as stated earlier or damn close to anyway.

anyone !

I don't think you're going to find anyone with an "other" opinion besides my "it's cheap insurance, do it". somehow, flogging the ring out of a turbo car in darwin weather on standard 98 RON fuel just doesn't seem like a smart idea. put octane boost in for safety and have fun. keep an ear out for detonation, helps to have someone trackside who can help as it can be hard to hear with a helmet on.

if the car has been tuned properly then adding octane booster won't do much as there should be no knock to speak of

but, if its anything below 100% perfect tuning, then adding some might prevent and mild knock and might prolong your engine that little bit longer...

the "its cheap insurance" line has to be true, i mean for $10-20 a bottle and the peace of mind that you probably won't have any pinging... i personally think why not?

[noone]

Thanks for the opinions my "other " comment should of read more like bump certainly no offense meant.

Yeh tune was pretty good no real knock to speak of ever

Ended up chucking some in and having a damn good time, street tyres on track is "interesting" no pinging overheating or any issues so happy as could be, maybe a little dehydrated though damn hot in helmet and long sleeves n pants in the tropics.

Appreciate the help guys

a whole bottle of nulon pro strength in just under half a tank of shell v-power 98 into my gts't auto a fortnight ago when tookit dragging. I noticed a good difference mainly because it stopped the car pinging like it does even on 98..

my gts t still has the little green sticker in the fuel filler door that i believe states use 100ron fuel only..lol.

imo, it's a big waste of money. I've seen tests done on the octane boosters, and they contain one or a combination of different sorts of active ingredients.

Depending on what it is, it might actually be detrimental.

e.g. adding ethanol boosts octane rating.

I forgot what the term is, but ethanol also has less kj of energy per mol that you burn. I think that's right.

Like people say with the shell extreme 100 octane, you need a lot more ignition timing to run it, otherwise you make less power.

IMO, don't waste your money. It's just marketing. Full sik octane booster makes your car sik.

I drive my car hard everytime I drive it. I don't use octane booster.

If your tune is safe (e.g. checked on dyno), I don't see how using octane booster will make a difference.

If your tune is not safe (e.g. leaning out), then I don't see how using octane booster that one day will make a difference either. If it's always lean and pinging, what's one more day?

tip a few litres of methanol in your tank

[Kennedy]

Put it on a dyno first.....adjust if necesasary and then head out to track

[Busky2k]

Octane booster sucks because they use MMT - stuff which coats your O2 sensor, spark plugs and pretty much everything else.

I would not advise putting methanol in your tank as its extremely corrosive. Adding 10% ethanol would be an alternative however you may need to richen up the car a tad because of the leaning effect of ethanol.

[Beer Baron]

i wouldn't run with the octane booster. as mentioned above they have a few downsides. and they add sweet fck all to the octane rating of your fuel. going from 98 to 98.3 is going to do bugger all except make your plugs and dump pipe, and 02 sensor turn orange after a while from the crud in the additive. as for one brand adding 30 points I call bs on that claim.

[MANWHORE]

I have yet to see a test on additive that adds 30 points as they claim.

The bottle of boosters are so small. If adding a few mL to 60 L will add 30 points, it must be some serious tarzanian man juice

[djr81]

Hmm couple of things.

Don't add any fuel additive that changes the density of the fuel. This is just asking for trouble. Yes ethanol will change the density of the fuel.

If you are using a hudrocarbon additive don't touch the stuff or get in on your paint. Cyclic hydrocarbon molecules are seriously evil things - don't breath the stuff in etc. Specifically I am talking about toluene, but this applies to most other additives, even oils & hydrocarbons in general.

Choose your Octane booster wisely. I use this stuff. If you only run it periodically you will find the orange cack doesn't build up much if at all - atleast that is what I have found.

Chances are if a product is marketed as octane booster & fuel injector cleaner it does sfa to the octane rating.

Just my 10 cents.

[Busky2k]

The "proper" octane boosters do work such as Wynns Race Formula and Nulon ProStrength. There is plenty of tests done and it adds approx 2-3 RON on 98 RON fuel. Its the dodgy $10 stuff in a bottle thats good for nothing.

[blackprincegts]

dunno ifits been covered b4 but my mate rekns if u take mothballs and disolve them in a bit of fuel and strain the wax out then put the liquid into the fuel tank thatit increases the octane like crazy...

no idea ifits true. lol.. anyone know?
