It is a lot of fun to tune with and you can make really good power. I have a big case of 80% methanol/20% Nitromethane I had custom mixed sitting in my spare bedroom waiting to be used when I decide to install alcohol inj. on the srt6 You see some very nice gains running the nitromethane mix in there!
