pump+meth VS race gas - SRT Forums

SOOOoooooo

Im curious to know the main differences in the two?

Ovbiously im a meth fan, and saw a new thread asking if anyone has reached 550-600 whp just with pump and meth?

I never know what to tell people when they ask what kinda octane i run. Just say 93 pump and meth lol. I dont know how to estimate the octane rating when you spray meth into your system? I know it raises it a hell of alot, cause w.o it i would knock my ass off.

SOO Around here we can get 100-110 114 and 116 oct fuel.

So compare those ratings to 93 pump+ 100% meth. ALSO asuming it will make a difference how MUCH meth your pumping into the system, will raise or lower the octane rating.

anyone got a good idea on any of this math stuff? Cause im lost. I think we have talked about this before, but knowone really ever had a answer?

P.S Race fuels: do they have any kinda special additives in them??? oils? lubes??? ect?

I know evo and sti's have had done it, not quite sure if someone has done it in a neon.

why not try 116 and meth

What would be the point of the meth (118 octane) when the gas is already 116 octane? I'd just run 116 and 100% water for the cooling properties.

This is an excellent suggestion.

I dont run race gas WITH METH, the whole point of meth is so you DONT have to run race gas all the time, its much cheaper, and tuneable. Just wondering whats gonna get you more octane.

racegas

Chief · 08-29-2009, 12:55 PM

so meth is a good DD way of getting higher octane, and not knockin. Where race gas will be the same PLUS some? So if i ever run race gas should i turn OFF the meth? Or spray with race gas?

meth is 118 octane and a fuel. That pretty much answers all questions if you know basic math.

You'll never get 116 octane with pump and meth unless meth is your primary fuel. So it's obvious racegas is more effective at giving a higher octane. And its stupid to try to increase the octane of a 116 gas with 118 meth. Just inject water with racegas, it has twice the latent heat capacity of meth = cooler charge. And it won't richen you up.
