Sitting here with the winter blahs, thought came into my head...what is my horsepower out there in the garage on my old '97 Coupe? Here's current power mods:

blackwing and smooth CAI hose, Corsa pace car catback, Dynatech headers with cats and X pipe, some sort of bench tune when headers were installed.

What makes the most sense from here on out with no engine block work?

Is your car an automatic or a manual transmission?? Automatics have about 5% more drivetrain loss on a dyno.. I'd say 310 for an automatic and 325 for a manual Based on SAE corrected numbers on a dynojet 243.. A Mustang dyno will give you around 295 hp with a auto trans or 310 with a manual.. If the numbers are not corrected for Density altitude you will see 335hp on a cold dry day in low elevation or 275 hp on a hot humid day in Denver Colorado.. Hope that answers you question

Spend $100 and have it dyno'ed if your really that curious.

They are just numbers, benchmarks if you will, that help with the dyno tuning process. To compare dyno numbers really doesnt mean a whole lot in the grand scheme of things when you consider how different your readings could be from day to day or dyno to dyno.

it's an A4...thanks for the responses...I think when I go to a 3:42 diff it will feel like a bunch more HP.
