Xr Dyno Sessions 446Awhp@7800Rpm 1.45Bar

Did 4 pulls at the AWD dyno today. Baseline (1bar/WG pressure) , 1.3bar, 1.4bar, 1.45bar.  Injectors are completely saturated  - even at 1.3bar I was hitting 88%, but I knew that. Wanted to get numbers before switching to 1000cc Bosch injectors and further upgrading the fuel delivery system. I was able to data log alongside the pulls, so I'll add those graphs later. My readings for AFR & Inj duty closely aligned with the dyno logging, which is good to note.

 

Also significant timing pull in the midrange, so the rich AFR's there don't help torque numbers. With this dyno, they go WOT early & let the dyno build the load - I have to wonder if this gives the timing pull in the midrange, cos I don't see that in highway pulls, going WOT around 3800rpm.

 

EDIT: Added Innovate logging graphs & data 8:20pm

Anyway, hit 446AWHP at 1.45bar, so pretty happy with that. DynoJet comparison is listed over on the right side - about 18% higher or 526AWHP - not that that number is meaningful in any way.

Torque split F = R is pretty much 50/50
