If your getting no KR using the 94 octane, then use that. There is no need to go with 112 octane. You typically want to use the lowest octane that you can that will not give you KR. Once you start showing KR, the car will start to pull timing. So yes, you will get alittle better performace with the 94 showing no KR. But like I said, not worth it to pay for 112 when 94 is doing the job.

I thought the 112 had lead. I know you said at the track, but if you liked the results I'd bet you would dump some in on a regular basis and then your cat would suffer.
I agree with the others, no KR, no need, unless you want to try and bump up the timing and by doing so create a situation where KR rears its ugly head.

VP 112 has a fair amount of lead in it; about 4g/gallon if memory serves. If you aren't running a lot of static compression or a forced induction induction application you'll actually run slower since the car will be pig rich. You'll also take out the cat real quick, too.
By way of contrast, at the track I run VP C16 (116 motor octane) in my '87 GN which has a good sized turbo running a fair amount of boost.
Hope this helps,
Morgan

Nacho,
I mean no disrespect, but how much experience do you have working with high octane leaded fuels? 112 octane is far too much for a stock compression N/A application; the only reason to step up to such an octane are for the reasons I noted in my post above, or if one was running a siginificant amount of spray on a high compression motor. If I were to put a 100 shot on an LS4 car I'd be inclined to run VP Red (100 octane unleaded) or even VP Motorsport 103 (also unleaded) to give me a little extra insurance at the track. Prior to getting her Charger my spouse used to run a LSX guru/dyno-tuned '04 LS1 GTO out at CA Speedway and pull low 13s at 104 on 91 octane. Even if scarlett were to employ additional tweaking the 112 would hinder, not help.
Regards,
Morgan
