DYNO: Before and After PPE Headers
EDITED the Thread since it had old information. Here are the results:
NOTES: The car was in Snow Mode for all the pulls, the machine is a DYNOJET.
BEFORE: Intake + Midpipe + Exhaust
AFTER
TOTAL GAINS 12.5 WHP or 4.77 % HP Increase

265 is pretty standard for a stock 350... it's tough to know how good the runs are without seeing the full plots though... the dyno should be applying some sort of correction factor (SAE usually) to adjust for temp, humidity, etc.
don't see mods in your sig, but if you had intake and an axleback I'd expect 275-278...maybe 280ish with a midpipe too or a full exhaust.
4th is the correct gear to dyno in because it's 1:1 for the transmission... snow mode is so it's less likely to downshift when you floor it.

I was expecting more than that (264), but Im gonna go probably 2 or 3 times more before putting in the headers. I think caymandive got 270 with almost the same set up that i have. (joez intake, megan midpipe, and tanabe axleback)
Really anxious to see the dyno numbers after the PPE headers are installed.
Juice 14: Do you have a 250 or 350?
Thanks for posting those numbers and keep us posted once you get those nice headers installed. =)

well, again, the dyno operator ought be applying a correction factor (SAE most commonly) that takes the temp into account... without seeing the full sheets though we can't see if he did that or not
Have shop give you a copy of your runs on jumpdrive. Tha way you have them to display & compare as you like.
