Nhc250 Max Rail Pressure

[Crf450x]

What’s the max safe rail pressure on these? I’m planning to install a gauge and my options are 200 psi or 400. The truck is stock right now but may not stay that way.

I have searched and searched for an answer and can’t find anything....

Go with the 400 gauge.

You can get 220 to 240 easy. Cam won't last long up there at those pressures though

Awesome. Thank you. Just for reference what’s a safe number for cam longevity? Stock is around 180 right?

170 to 190. Just depends on where she pulls best

Correct around 175 /180. I set mine at 200 no more. I also just went with a 200 range oil filled gage. Made this up to do / watch the pressure rise and fall when test driving the 250's.

Thanks guys. Going with a 400 psi isspro drive oil pressure gauge. The words won’t be right but it matches my other gauges.
