Increasing Gasoline Octane Overseas

JWillis72 · 04-24-2014, 11:05 AM

I recently watched a BMW dynoed with 93 and then again with 93 with Boostane added to it. While it took a few pulls for the car to react to the change when it did the car went up just under 60whp. I've never had any faith in gas additives but Boostane definitely increases HP.

Just as an FYI, unless it only had a gallon of gas, and the car was tuned for like 100 octane, the dyno pull you saw was a sham.
Either the operator was doing something or maybe the car wasn't warmed up in the first run. My car gained 10-15 WHP from the first pull to the last pull when oil temp went from 180 to 210

Unless it was one of the turbo ones,

Even then I probably still

It was a M3 so yes it had turbos and Z1 posted similar results recently on a turbo car. If it helped gas on a turbo why wouldn't it on a NA car? I've never owned a turbo car so fill me in if I'm missing something.

The higher the octane the more you can advance the timing. The more you can advance the timing without getting knock, the more power you can get.

On an NA car the hypothetical gains that are possible aren't that high because there isn't that much going on I guess.
On forced induction it allows you to force more air and more fuel AND advance the timing

Correct me if I'm wrong guys. I know it's a bit more complicated than my crap description, but I tried to keep it simple

Looks as though I will have to go downtown to find the toluene. I checked on base at a couple locations with no luck. Apparently the local city used to carry 97 Ron but since it wasn't being used as much as the 95 Ron they discontinued it. I will keep you posted on my finding and DEpointfiveO when I find the paint thinner I will run any additional constituents by you and see if they will have a harmful affect. Thanks again for everyone's input. This is why I come to the 370z side of the house way more performance based

Depending on how long you'll be there and how much your total fuel cost per gallon is after adding the toluene, it still may be more cost effective to get another map to run the pump gas over there. That way you could have your 93, 91 and then a low octane map. That would also come in handy if you're evey in the middle of nowhere and don't have the option of good gas.

I will be here for a year longer then Germany for three years. So I just have to get through the next 12 months in this dilemma. Then I am sure Germany will have all the octane ranges I could ask for. Good point with the tune and that maybe another route I will check into if this fails or the cost ratio just is not going to cut it. It's not like I am drag racing here or running FI. It's more of a piece of mind with breather mods / factory gasoline octane guidelines.
