lm looking at installing tank and pump in trunk.
lve been told to inject pre-turbo this is a twin turbo set up
? how long will 1 ltr last (recommended tank size)
? can l use in tank foam to stop surge if using methanol.
? water only or water Methanol mix
? twin injectors 1 per turbo Pre-turbo or single injector after IC
? injector size
? what would happen if l ran out of water / water methanol.
? should l tune engine on fuel only first then add water injection later.
