NA vs 100 dry. placement of the dry nozzle made this only achieve 65 rwhp. fuel pressure dropped 4 psi.

NA vs 100 wet. this is the first time i ever got more than what the jet chart rates the given jetting. got 123 rwhp out of it. fuel pressure dropped 4 psi.

NA vs 150 wet. got 152 rwhp out of a 150. fuel pressure dropped about 10 psi by the end of the run. starting to see a problem here.

NA vs 100 dry and 150 wet. 100 dry at the beginning of the run at 3200 rpms and the 150 wet on at 3900 rpms. fuel pressure dropped 15 psi before the end of the run and aborted. end result, factory fuel pump is giving out. the drop wasn't slow either. 192 rwhp out of a rated 250 shot. with a better fuel pump and getting to peak rpms, i'll most likely get real close to the 250 rwhp mark.

on the dual stage i started the run at 3200 rpms with the 100 dry on. at 3900 rpms, the 150 wet came on. you see it didn't start recording the run until 4000 rpms. gotta love winpep7. this dynojet is a 224. 2 drums 24" diameter. most people run on the 248 2 drums 48" diameter. with windows based dynojet software, if the inputs don't math the programming, it tosses out the data until it starts to agree. next time i get on, i'll use the inertia load. i was on no braking just like most of the dynojets out there have.
funny thing about the inertia loading on the dynojet. every car we had at the dyno day that we compared unloaded to loaded, the loaded numbers were higher. really weird. one car was 317 unloaded and 342 loaded.

i could get on vinci's dyno, which is still the original DOS based program. unfortunately, it doesn't graph a/f, which everyone is mainly concerned about.
