Also, because everyone (including me) loves dyno charts, here is a plot of our F30 mule baseline vs EFR7670 vs EFR8374. Please note - this is the same car (completely stock engine, exhaust, airbox/filter/tube) and same dyno, no garbage here. This is SAE correction (what everyone should use).
The 8374 has a lot left in it, but had run into dme torque ceiling limits or something (on dyno only, havent seen that on the street/track). These runs are at 24psi, have run up to 28psi on the street. I think the EFR8374 could put down 750whp.
Also have not run a 9174/9180, but those fitup on F chassis also, and should be good to nearly 1000hp. So if someone has a built N55 and wants to test out a 9180 let me know!
