Toluene is another option but either way... for a regular DD, maybe consider running a premium/super mix ?

Is that the same stuff found in paint thinners? I think I read somewhere it will damage hoses and rubber stuffies. (open to correction)

because they use ron + mon /2 which is higher than our ron @ the pump.

Toluene is an anti knock agent too much and you will out the flame, I would not exceed more than 10% on a grocery getter.

you do know the above kit is no better than the junk A@# WMI kits that are available locally pumps are only 150psi, no true failsafe, a led light to show flow, crappy nozzle.

apparently alot of shops and retailers stocking up on Octane Boost.

your guess is as good as mine.

9.8 and 9.9 CR's. thought the cutoff was at 10.
unless those are so close and don't retard that there's no room for error (NP).

If you are looking at water meth kits Aquamist is best, you can tap into your IDC and have the controller spray proportional to your IDC. You can do this and basically have A ratio of meth injected per gas used, this won't require much if any tuning if a the right size jet is used.

idc seems to be the best way to control flow. i havent seen much kits around that are idc controlled. perrin has an idc controlled kit as well [made by aquamist]

According to NP, their fuel ratings are RON.

If it was AKI, we are getting a steal of 95 AKI @ $5.75/litre.

Postby **tr1ad** » October 3rd, 2012, 8:15 am

^ not disagreeing, but the "poster" has the AKI rating, not the local RON

silent_riot · Postby **silent_riot** » October 3rd, 2012, 8:26 am

Unless I misunderstood, doesn't the pic with the Nissans say RON? That's coherent with NP's ratings of RON 92 & 95min.

Taken from the Mitsubishi CK Lancer owner's manual:

Carburettor Type:
1300cc - 90 RON or higher
1500cc - 90 RON or higher

Electronic Controlled Fuel Injection Type:
1300cc - 90 RON or higher
1500cc - 90 RON or higher
1600cc - 95 RON or higher

The manual specifically states RON and not AKI for the fuel grades.

Didnt we beat the octane topic to death before ?

Tnt numbers are ron, same as europe and japan, however, our gas is not similar quality. My original Honda ecu ran my civic just fine on usa aki 89 pump octane (regular in the states) and all but exploded when i poured in tnt super at 92ron.

I would figure that local super is closer to 85 or 86 pump octane if using (r+m)/2 method....if you have a car that can run on that without issue...then like yuhself.

Compression ratio doesnt hold as much of a priority as ignition advance when it comes to fuel octane.

is ecu reprogramming an option ?

agreed. possibly mistakenly came to the conclusion that the higher the CR, the higher the ignition advance.

I can't speak to the other technical comments made, but what type of lancer you have, an EVO?

I have a CS3 and I have been running super for a few years and have not experienced what you described. The only changes made were to add Iridium plugs and a K&N air filter. After over 150,000 km on super still nothing like what you described.
