The Alky Control pump pushes over 250 psi... plus as previously stated I have the M15 nozzle... I don't have a meter inline to tell me what my rate of flow is but it varies with the boost...
I know for a fact that I can max out and then some the amount of fuel the ECU will pull which is 29% of the total fuel injected at WOT. Then my AFRs drop like a rock...
But I adjust the kit so I don't have knock... so I monitor KR... once I adjust the controller so there is no knock I am done... how much meth I am pushing? Dunno... I am sure you could do the math based on the datalogs... but I don't care...
Last log with Brad showed me holding over 255kpa (22.7 psi) with perfect fuel pressure over 2200 psi and AFRs holding nicely.
22+psi spike or constant?
I have been thinking since the 15-psi build I was running was 'to hot' i might be able to go back to it with 30/70 meth. That would be awesome since the 15[psi build was way more torquey and seat of the pants fun at low speeds.
We had an interesting effect when Brad modified one of the torque tables..... the ECU was setting dsd tip to 255kpa... in third gear I was holding 255kpa for over a second without any impact to fueling... it was not intended... but it goes to show you how stout the Alky system is...
Here is my take... LMS was one of the first groups to throw meth at these cars (at least I believe so) and they don't do anything that's half assed... if they are good with the pump and nozzle setup, then it's probably extremely sound..
With the 10+ meth revs I have played with, I can without a doubt say that with the Alky Control setup, you can hold over 2200psi at the rail with any load you throw at the motor with stock turbos. Assuming 100% meth of course. At this point I see no need for a bigger HPFP...
I am curious about a full tank of E85 with meth injection... if I can offset 30% of fuel now... no reason I couldn't run full E85... it would just be curious how much load I can push with it..
You could blow the motor sky high due to too much torque and still maintain 2200psi at the rail.
