Just got a T3/T04B turbo, what do I need for Fuel?

Q&A regarding engines, turbos, and intercoolers and power upgrades

Postby furpo » Tue Sep 28, 2004 11:27 pm

yes that is true. water injection as far as i understand allows you to run leaner because you are no longer putting extra fuel in to cool the combustion you are putting water in instead so the chances of your engine melting are quite high if the water injection fails and you don't know it has. can someone correct me if i am wrong because i have never used water injection.

the air fuel ratio i settle on all depends on what i am tuning and where the results look best. i say 12 to 1 because this is the leanest mixture i have ever used as a full power mixture. note we have 98 as pump gas down here.

Sorry for going off topic..


You are correct in your WI statement above.

How is your 98 fuel rated?

In other words, the 94 (R+M/2) here at the pump = 98-100 RON

So is your fuel RON or ??

Thanks Gus, that's what I thought.

In Pennsylvania, we can get 94, which is between 98 and 100 RON (Source - Sunoco) Most stations carry 93.

In Arizona, I can only find 92 :( Most places only having 91..

The South West and California sucks for good fuel.

I thought Gull was 97.5 (I'm sure it says that on the pump) but you only have to pay for 96 - 5c cheaper :)
