Croustibat is an unknown quantity at this point
yup, no knock on e85. EGTs and cylinder pressure skyrockets,and then your pistons melt / the block or head crack.

I dont know the engine you use. I know a GT3071 on a CA18DET and a 9000rpm head requires 1200-1600cc injectors to get 2bar pressure (but then the turbo dies as it overspins) with e85. Dual fuel pump setup could be useful too, not sure it is needed. It also needs a true peak & hold injector driver if your injectors are low impedance, the oem saturated driver cant open injectors that big correctly, and you wont be able to map them correctly. You can adapt a megasquirt driver for that, it does not cost a lot, around 60$ i believe. Injector size also depends on your redline, i think 1200cc would be enough on that CA if the redline was at 7500 or 8000.

If it is on a sr or a KA ... i dont know, but i dont think it will need smaller injectors.
