I've been doing some testing and tuning the past few days. This is my first mcx kit and I'm a little Leary on boost pressures expected.. The recommended pressures seem pretty high for pump gas, so I want to be sure before adjusting
Sled is a viper with 270 kit
Instructions indicate 15psi @ sea level for 91pump
I live at 1800 ~ 2000 ft, where I'm testing..
Out of the hole it spikes to 17, and quickly bleeds back to 15 or sometimes 16 (digital AEM guage, whole numbers only, no decimals)
I'm guessing the spike is created by the automatic altitude pressure compensating valve.
I did a quick google search and 2000ft is about 95kpaa or 13.7 psia.. Doing the math one would expect 1 psi additional pressure to compensate for my elevation (13.7 ~ 14.7)? Correct?
Does this make sense? Is this safe?
I would have never ran 16psi on pump gas with my PL nytro @ 2000ft.. I ran more like 12 psi, and 15-16 at 5000ft and up. That being said I realize the kits use totally different gear.
Thanks in advance
