Timed Duty : Direct Port Injection

[rotrex]

so for you, you could leave the injectors for the petrol at the OEM location.
Install a second set of methanol injectors further upstream and/or pre turbo.
Run a 10l fuel cell with own pump etc. for the methanol or ethanol.
Red Victor, a 2000HP+ street legal drag car running methanol, injects both before and after the turbos.
Add water nozzles whee you deem them useful and skip the sequential injection.

If you need to inject all your fuel within those 9ms, you need really big injectors.

Question is if this is really worth the trouble for the HP goals you have?
As your car is FWD with limited tyre width you will likely already be at the traction limit as is.

The present plan :

- 4 nozzles (working on sizes) into the intake plenum runners running a 50/50 mix of water/methanol. The car is street driven and could happen to stay parked hours in the sun. A 10ltr pure methanol tank in the trunk would be actually dangerous especially in direct sunlight moments.

- The engine will be a 12:1 compression so injecting at low boost is critical. Engine is targeted to reach 330bhp @ 14psi. Actually preparing the engine for 400bhp+ but the turbo is the limiting factor.

- The water/methanol injection is going to be used mainly for high compression safety even at low boost. Second is to use the WM50 system to increase efficiency of the engine by set it as a base fuel @ wide open throttle. Target is to reach current power level with the least possible boost.

- I saw FWD running high 8sec 1/4miles with 600bhp levels.... so why not shooting for 400bhp.

The question is would you prefer get to that level with More boost or More methanol ?
