    Question RE O2 sensors in vintage race cars

    I haven't purchased anything yet, but I'm looking. The AIM stuff looked particularly attractive to me because I could use it for engine/driving data and could program some warning lights if something isn't right. I would like to get your input though if you have any recomendations. Thanks!

    Question RE O2 sensors in vintage race cars

    Rad dudes of VRO: I want to install a wideband O2 in my 914 to keep an eye on my tune and potentially assist with dialing in my carbs. I don't really like the look of the modern digital gauges on the market, and I'm not sure I like the idea of trying to read an analog gauge either. I have...

    RACING ENGINES, A TECHNICAL EXAMINATION

    I love this: Physics does not change, it is our understanding of physical application that, evolves, mostly due to "changing of limitations", or perhaps "clarity of understanding". Well said Mark!

    So you don't like the idea of ethanol in your race fuel?

    Thanks for posting this Mark! Although I'm not sure my race engine was necessarily tuned/setup to run leaded gasoline, the previous owner used to run low-lead aviation fuel in it. Other than a potential change in AFR, what other things should I look out for when making the switch to Sunoco 260GT?

    So you don't like the idea of ethanol in your race fuel?

    Mark, I really wanted to defend my "100% Race Gas" stance... but then you mentioned "data"! (and I realized I don't have any) -jz

    Looking for race gas near Chicago

    I was looking at the "Surge" as it's leaded and contains zero ethanol. The 260GT is 10% ethanol which I'd prefer not to use. It's going in a 1971 Porsche 914 race car with 9.5:1 compression. the guy I bought it from ran 100 octane low-lead av-gas (which I'm not able to source) I'm not stuck...

    To clarify: I was looking to mail order Sunoco, but found out they want $100 for shipping (for 10 gallons). I'm hoping there is a local place I can walk into and purchase. TIA!
