Have a question on race fuel!! I have the 93 octane race tune on my 2912 GT with shorty headers and Magna flow cat baca with free flow cats!! My question is, I can get 110 octane fuel for when I go to the track!! With the 93 octane tune will the gas make it run like sh** or blow engine or wi the tune adjust to the higher octane!!
Any info you guys can give me I could really use it!!
Or should I do a Dyno tune on it!!! This is a dd car!! Thanks alot.

First off congrats on the car that doesn't come out for another 899 years :lol:

But seriously, you wouldn't benefit much from 110 octane the copperhead ECU won't adjust for more than 3* timing, you'd really need to get a tune for that

Thanks!! Sorry about the type o. Dn phone types what ever it wants!! I figured I would have to have a tu e done!! But I'm not going to drive it and pay $8.60 per gallon !! I was just wondering how it would run. Thanks again

You will only benefit from the higher octane if your running FI and trying to put a bunch of timing in it. No real worthwhile benefit on NA unless your running insanely high compression.

I know on my ol' 1990 fox body notch....the VP 110 made a big difference. I guess these modular motors have come a long way.

you can prob manipulate your tune to change a few things that might help,,I know when i loaded mine there were alot of timing options and different parameters,,but you have to know what to change

Yep, there's a big diff between an iron wedge 2V truck head's det resistance and a basically hemi, DOHC, independently-adjusted cams 4V aluminum head, especially with an ECU that has a zillion times more processing speed and power. Basically comparing wiring your knife to a stick or calling in an air strike on the gunfight....

Like I said.. I was just wondering!! I used it when I reces Motocross in my 450 RMF. And it did make a huge difference in power, but that was only a single piston!! I'm sure there's a lot more to a v8 and it!!! I'm sure if I wanted to go into the motor and beef up internals and high compression , it would make a large amount of HP TQ!!! Thanks again!! Really, I love the way the car runs nos, just need to do sW exterior work now!!!

Engine tech is constantly evolving and comparisons across platforms and applications are difficult to make (!!) If this wasn't so, they would have sussed out all the big stuff by the end of the First World War(!!)

Come to think of it, let's look way back....OHC? First used successfully by Hispano-Suiza in WW1. DOHC? Shortly thereafter. Nitrous oxide? Used by the Germans in the BF109G in WW2. Direct injection? Same. 4V heads? Supercharging? Also WW1(!!)

What's changed is manufacturing processes, metallurgical understanding and, most important, electronic engine management(!!)

The takeaway is you need to learn how this platform works as the technology present in it determines different outcomes than dirtbike or old pushrod iron experience. You're doing that by asking here.

I find the evolution of engine technology interesting as well. Our forebears may have had great ideas in isolation but, it's the synchronicity of many supporting technologies that allow something like the Coyote to come to pass.

The simple fact I can datalog over 100 engine parameters on a device barely larger than a credit card is an example. Supporting technologies are, the ECU needs to be monitoring those parameters, the sensors need to have the resolution to make the data useful and the electronics inside the box need to be sufficiently advanced to support miniaturization and data storage volume necessary.

Back to 110 octane: Unless you can tune specifically for it, you are not likely to see much gain, if any, unless the engine has already crossed the det threshold.

NO! Don't do this!
