¦ Keeping it simple
The best way to accurately dyno test an altitude compensated turbo engine is to dyno it at sea level. It would be interesting to locate the ACE 900 Turbo’s ECU baro sensor and pressurize it to 29.92 in. hg to set the boost pressure at sea level HP levels. But, then we’d have a bit less actual atmospheric pressure forcing air into the turbo. But with all the tamper-proof sensors on factory turbo sleds it’s unlikely to be that simple. For now, I’ll consult with my dyno-savvy engineers to see if making a 3% deduction in CHP to compensate for DTR facility’s 1000’ altitude might make sense. Will BRP make a 200 HP 850 Turbo now? We hope so!
