When is that 15 HP ever going to make a difference?
I'm not hating, just trying to figure out why someone would do it?
Particularly since at least a couple have had blown motors.
.
Meth is worth a lot more that 10-15 HP on a supercharged application like this if it is tuned for it. That's the problem...you can add meth/water but the ESS/VF tune just adjust the timing tables for the lower IAT's and so there is a slight power increase. If one tuned for the drop in IAT's and higher effective octane rating, a far greater HP increase could be acheived. So, has anyone done this on an ESS/VF kit?
