Gears have 0 impact on HP.
As to the difference between yours and his, different dyno different results.
Ive been on a dyno-jet and put down 465 hp 494 torque
And on a mustang dyno put down 412 hp 445 torque (both on spray of course!)
I know for a fact my car is nowhere near the dyno-jet numbers, but they are nice to see!
It all comes down to different dyno different day, thats it.

so are his 3.73 dropping his RWHP.....very nice numbers with your setup...congrats...just curious...as Mine was 300.8 with same mods and 304 torque...without the gear change....

Very nice. Your numbers are pretty much dead on now with the mods you have. A/F is dead on too.

also, lets not debate over which system gives more accurate numbers....that horse has been beat to death...
p.s. my 300.8 and 304 were acheived on a MUSTANG dyno as well.not a dynojet...so I guess based on your response my dynojet numbers would have been much higher and skewed? ..I attached my sheet from back then....

The first thing to look for on a dyno run for NA cars is, do the HP and Torque curves cross at 5250 RPM. If they don't you've got some problems with the way the dyno was set up. I've had mine done at two seperate places, and the curves were a joke.

I honestly don't know how they dyno'd it. The shop works with S197s a lot and is pretty reputable, so I assumed they knew what they were doing.
So, cheftjpeck, you are saying that since my car doesn't show a dip early on, either they correctly locked it in fourth, or (incorrectly)ran it in third? And if there is a dip, that means it was run in fourth by turning O/D off (and not locking it in fourth) and the small dip is due to the car shifting into fourth early on?
They also gave me the dyno numbers before the SAE correction. I found it interesting that the non-SAE corrected numbers are actually higher (by about 5-10 HP) than the SAE corrected numbers. I am assuming the standard temperature/pressure is something like 70 F and sea level? It was about 80 when I had it tuned. I would have thought the SAE numbers would have been better...

pretty good numbers for an auto, i guess. i'm puttin down 10 more HP w/ far less mods on a manual. the torque curve looks, uh, weird. i don't recall my curve being all over the place like that. am i the only one who thinks the torque curve looks funny?
btw, take note of my numbers and mods. this was in 100+ temperatures.
