C16 vs. VP104 vs. alky
I'm ready to move on to tuning my car on something better than pump gas and am wondering whether it is worth it to get a test pipe for racing (I usually have a cat) and get into a pattern of replacing O2 sensors as they wear with leaded gas.
How much more timing/boost can you run on C16 vs VP104?
How does methanol injection stack up to either C16 or VP104? I have the sense that it's better than 104 but not as good as C16.
Thanks for any advice.

I'm not the MOST knowledgeable...when i talked to my brother..he said that alky was bascially the replacement for those who don't have the access of c16 or racefuel for that matter..but want to be able to run the same boost levels safely and efficiently..

If you run the AEM and the kit is wired up to it you can control things if it is to run out you will be fine.
But there is no compairison to running race fuel , hands down. You will always make more power on race fuel. Don't get me wrong alky injection does allow some cars to be maxed out and get close depending on the setup but from a tuning standpoint you can get more agressive everywhere with race fuel.

BUT, for day to day, you can't beat the alky. But c16 for best track performance.

VTECH8TR and I could tell you a few storys.
Umm, Alchy isn't the replacement in the long run for Race fuel. It helps though. It is like making 93 octane 98-100 octane. Race fuel is race fuel Leaded or non liek C16 116-120 octane.
You can even do race fuel + alchy for even BETTER results.
And for the people with horror stories if you have a kit that is capable of a warning light you wouldn't have to worrry about running out. You see it is low lower your boost and change your fuel map off of the alchy map.
Boost wise depends on the turbo but you can add more boost lean out the fuel and add more timing. All depends on turbos.

With sunoco 116 and leaner a/f I went from 111.99 to 113.62 and probably had a 114 in there but missed a shift to 5th.
For daily driving and on the street, meth is the way to go.

You will get better results on race fuel vs meth/93. But, 99% of us don't have access to, or can't afford c16 every day...so 93/meth is one helluva replacement for day to day.
