1- Approx 8 to 10 % PerCent increase in Torque/HorsePower potential
.....most times, a simple switch over shows instant Low-end to Mid-range Torque and HP gains , but no real Hi RPM gains because Methanol reduces VE %, and Ports need increased cross-sect area, and Carb CFM has to be 200+ CFM larger to account for more wet flow loss -vs- Gasoline
2- Approx 10 % PerCent "LOSS" in Volumetric Efficiency with no other changes except Fuel switching
3- Approximately double CFM in Blowby readings
example=> 4 CFM on Gas = about 8 CFM with Methanol
using Methanol increases Blowby, Ring and Valve Seat wear
Increased water in oil.
4- Could run 16:1 CR + because Methanol in comparison to best Race Gas has higher effective resistance to detonation, and the other reason to run higher CR is because of the previously mentioned LOSS of Ve %.
if the Ve % Loss is corrected, Comp Ratio might have to go lower ?
5- to build a Methanol specific engine, then Intake port cross-sectional areas would have to be larger, Cam Lobe/Lift increased.
The Canted-Valve Chevy Head or similiar Head would allow more cross-sectional area / Flow / Valve Size
Header with Collectors could be used instead of "Zoomies"
