I agree, check out the water injection for the safety margin, although the pump says it is 93 octane, it does not mean you got a quality product. Also gasoline as it sits will drop in octane. My uncle hauled gasoline for years, the Sunoco Ultra 94 comes out of the plant @ 108-111 Octane, but with it being mixed with the gas in the tanks that has been sitting, you are getting an average minimum of 94. If you have a few extra bucks, have a private company check the pumps you frequent, some of you might be surprised how high the acctual rating is on the gasoline you are pumping in your cars, the octane rating on the pump is the minimum the gasoline has to be be to meet state testing. My uncle said he had delivered a few loads to the stations and their high octane tanks were not low enough for the full load, and the managers just had them dump the excess into the lower octane tanks. This is something to think about the next time you go to the pumps...

An easier thing to do would be to talk to the station manger, or if you get the chance, the driver, they will tell you the same thing, the stickers on the pumps are the state minimum to carry that label.

18 psi on pump (93-94 ocatne) all day long......
timing and A/Fs in the 10.8- 11.0 is the key https://www.nopistons.com/forums/pub...#>/biggrin.png No race gas......the reason why my FJO wideband is still running awesome after one year..... |

In the words of Corky Bell "water injection makes up for poor tuning".
If you don't know who Corky Bell is maybe you shouldn't have a turbo in your car. |

This is from an email I received from a friend of mine:
"I am running 20psi, but that is because I lowered the compression ratio of the motor. Boost pressure is really meaningless unless you are holding constant intake charge temps, spark plug heat ranges, ignition timing (and how precise the ECU controls it) and the compression ratio of the engine the boost is going into. In my case I have a huge intercooler, a turbo that is efficient in that range, colder-than-stock plugs and the most advanced ignition controller available on the market. Further, 20psi in my engine is the equivalent of 18psi in a 9.0:1 engine. 18psi in a stock motor isn't really that big of a deal as long as the other concerns are dealt with. Best, John" |
Re: 18 Psi On Pump?
you can go up to 20 psi on 93 but after that your going to start getting into c116.
