The present IC doesnt seem to be able to quite achieve this as I think was indicated by indicated by Boost Monkeys Ice tank tests, but assuming the rcompart + Waldig super cooler can.....you can note the difference in the last 2 sets of numbers. Same psi output from the MAP but very different rwhp numbers....
SC Pulley.... Final MAP.... Fuel input per injector..... lb/hr/injector..... Inlet Volume..... cooling..... cooling..... .....IAT C..... IAT F .....rwhp..... density
74mm..........14.5psi............ 447cc..161lphr........... 42.6................. 607cfm............-11.7kW/hr. -40kBTU/hr....50......... 122....... 290...... 2.15kg/m3
74................15.1............... 456.....164................. 43.4 .................619.................-12.7.......... -43..............50...........122 .......296...... 2.20
62................18.1............... 481.....173................. 45.8 .................654.................-11.9...........-41..............64.......... 147 .......305...... 2.32
62................18.0............... 500.....180................. 47.6..................680.................-17.7.......... -60..............50.......... 122 .......315...... 2.41
It would be good to log (and compare) density numbers rather than psi. That's the clincher!
I dont have a dashdaq or similar, but if you can pull in the MAP and the IAT it can be calculated.
Great, thanks for your reply. Just wondering:
- How did you get those numbers? OBD2?
- How do you measure the fuel input per injector?
- How do you measure the inlet volume? Is this value measured from the outlet of the SC?
What is the max CFM that the SC can blow?
