Tuning N/A 110 octane

Jordo! · 03-18-2011, 11:42 PM

If you're feeling really adventurous you could mix in some nitromethane...

I guess the big question is how much extra advance could you coax out of the motor with 110? Worth a try, I suppose

not worth a try without larger injectors or at the bare minimum uprev. you'll be running lean instantly.

What -- just with high octane? Anything with a high O2 content, sure, but just high octane shouldn't do that.

I just don't think there's more than another 1-2 degrees to get out of the timing -- I think it's pretty close to optimal as is. Maybe if valve timing could also be adjusted.

I think he was talking about nitromethane. That's funny stuff. Do that on this engine and this is what will happen..

Every fuel has it's place.

Regarding additives; has anyone pulled the plugs to ensure they aren't leaving deposits? You know, I just had a Mustang the other day, ALL 4 o2's were smoked because the previous tuner told them that additives are ok. I am all about more hp, but I've seen time and time again o2's smoked when running an additive. I never really kept up with which ones are harmful, I know there are some with a hint of... I believe manganese (?) and I want to say, the Torco blended additive ruins o2 sensors also (I know there's more) I would say, if you want, and I hate to say it, use pure methanol and a methanol injection kit. (racing methanol, not denatured alcohol like I used to run) M-1,5 or whatever. Keep it on a switch and have UPrev map switching function for a separate map. There all the time for when someone is talking trash...

Unlike a TURBO car, if your kit cuts out you just loose a bit of power assuming you aren't running insane timing. I'll never use meth injection on a turbo car again. Too risky.

What do you guys think? I'd love to see someone try this for a back to back comparison.

toluene is factory component of pump gas, it's safe, yes nitromethane brings it's own oxygen to the party so you have to run huge amounts of it to stay rich, i wouldn't recomend using straight methanol as the main fuel as it corroids all aluminum engines but it should be fine for turbo injection systems(which really should be used on cars with a tuning solution that can tell when it's out of meth/water and pull timing for you like an fcon)

Toluene = 114 oct.
Xylene = 117 oct.
Both are aromatic hydrocarbons.
You decide.

don't

me, we mainly came down to the cost issue and for 5gals toluene is around 40% cheaper
