Thanks for following!
Unfortunately the fuel limits were reached. It was pretty warm out too...
Timing was being pulled due to the temps in the shop... at 15psi I was getting 13.5 degrees timing vs 15 degrees last time. We didnt want to start modifying the timing tables for coolant temp.
Raw numbers weren't bad...
18psi - 945rwhp/983rwtq timing at pk tq 12 deg, 13.5 deg pk hp, 11.5-11.8 A/F
20psi - 990rwhp/1031rwtq.... but stopped the run at 5400rpm because it was lean timing at pk tq 12 deg, 13.5 deg pk hp, 11.7-12.0 A/F. Injector DC over 80% and fuel pressure was dropping off to 45psi during the run. It wasnt happy as hp peaked at 5100rpm as seen in the graph.
I called it quits at that point as I'll need to address the fuel system... Not bad for 1000cc injectors, FPCM and ZL1 pump. Meth really let me stretch this fuel system.
FYI... we were very conservative on the tune thru all boost levels as well were trying to get to the high boost. So we were high 10.8-11.2 thru the lower boost runs.
Here were the SAE numbers with the conservative tune:
8psi - 660rwhp/744rwtq (wastegate) 12deg/15 deg and 10.8-11.2 A/F
15psi - 872rwhp/894rwtq 12deg/13.5 deg 11.0-11.4 A/F
18psi - 923rwhp/960rwtq 12deg/13.5 deg 11.5-11.8 A/F
20psi - 966rwhp/1006rwtq (partial run) 12deg/13.5 deg 11.7-12.0 A/F
Conservative timing... need more fuel... made about 15 pulls... will go back after I address the fueling. She will absolutely do 1050rwhp for sure.
