[up_in_boost]

Like the tittle states... I heard 100% meth Equals to like 96OCT???? Just want to know to see how far i can push my tune using 100%meth. Tried searching but didnt find the info i was looking for. Thanks

Last I read Meth has a octane rating of 110

[Chief]

depends how much. and what octane you start with. Nozzle size dp or single what psi. lots of factors.

[up_in_boost]

So it's like 110oct? Give me a example of the veriable your talking about?

[Chief]

I have no idea, thats just simple facts, it will depend on teh ammount your injecting will change the octane rating.

113oct (R/M is 99 octane)

RON/MON pump rating

like nutz said 113

[nutz]

its octane isnt much but its ability to pull heat from the cumbostion chamber is huge and contributes a ton to eliminating knock, it will make your pump fuel act like it has a much higher octane rating because of the lower CC temps

so its better to have a mix

depends on the setup... some guys run 100% meth but typically you want ur mixture to have as little meth as possible.

so it equals to 113OCT?^^^^^^^ ok good..... So you guys think running just straight 100% meth will have the best outcome? Inregards to getting the max out of your TUNE?
