What are the EGT's at sustained wide open throttle?
IDK, I wasn't there, bit of a bummer. Mondays are full of meetings from 8am to 5:30pm. I'm told AFR and IAT were within safe limits up to 4K rpm.

I'm not going to worry about it if they stay below 900° C (1650° F) because it's running methanol/water injection (triggered by boost/IAT and a LUT) so it's getting a bit of excess fuel (which cools) and in any case, it won't stay WOT very long. With your diesel, you probably want to stay below 650° C (~1200° F)

There may be a dyno attempt again on Thursday and I may be able to break away for that.
 
only got to 370 rwhp / 500 ft-lbs because it's losing fuel pressure > 4000 rpm

going to have to find/fix that, then try again, see if we can improve those numbers by 10% or so.

New fuel pump, back to the dyno

410 411 HP / 560 561 ft-lbs at the rear wheels. Will post a graph later.

We’re now IAT-limited. The methanol helps but can only do so much. No room for a proper intercooler on this truck, and it doesn’t really need more torque.

Remember: Pua’a can also produce a 186:1 crawl ratio.

Sorry 411 and 561! Yeah Pua'a has some GRUNT and some seriously low gears!
 
Wow that dyno vid is crazy, brings me back to my turbo 4 cylinder days of yesteryear. Welp it's official, time to remove the carb'd 350 and slap in an LS and a turbo or two. No rocks around here to crawl anyways.
