[QUOTE="Black2003Cobra, post: 2772336, member: 3159"] Yes, I understand that. I understand the theory quite well. As a fuel substitute, its heating value is about half that of gasoline so it's not great in those regards, alone. Meth has a high latent heat of vaporization, which is very good at cooling the charge. This allows you to increase timing while avoiding the knock limit. (The knock limit is increased by the cooling.) It also has a relatively high ON, itself. And that's all well and good, and it has proven to work on many different kinds of cars. [I]But[/I] if you are already very close to, or at MBT (maximum brake torque) timing, then the power gains per degree of timing are slim to none. And of course exactly how much you gain per degree of timing will also depend on how much power you currently make. Etc etc etc. BUT, outside of this MM&FF article, I have yet to see anyone say they have achieved good gains with meth on an '03 or '04 Cobra. I'm not flaming or anything, I just haven't seen the data. If someone out there has seen good gains, then I would be very interested in seeing all the details. (How much timing was added, how much power was made, IAT2 data, etc). If someone wants the name of someone to talk to who has tried this on several '03 & '04 Cobras, PM me. [/QUOTE]
