Vader met the dyno today!

[Tommy V]

Hey vader I will post my pics of my 3 stock runs and mine did the same thing, progressively went higher.Stock was 387 and mag comp catback was 389.I did pick up 4 ft/lbs tq.The cat protection is going to be addressed in the tunning, when that kicks in it causes a really rich condition affecting horsepower, I seen this in my logs.

So ford advertises 435 HP and owners are only getting 375 -385 HP .
When a manufacturer advertises something ,that's what I expect it to be.

435 is Fords crank HP number. The 375 - 395 numbers are at the rear wheels

As Wilkinda65 said, the measurements are taking place at different points. When you measure at the wheels, you will encounter drive train loss. Which is why wheel hp numbers will be less than crank hp numbers.

I understand that ,but why doesn't Ford and other automakers advertise that instead of 435 HP at the crank?

 

[dubster99]

Because it doesn't sound as good. I wonder why these cars make power in consecutive pulls....not the first time I've seen that. Flowform got way more power after doing a bunch of pulls in a row after putting on exhaust.

the coyote likes to have some temp, usually your best pulls will be in the 190-205 degree range

That's what I was thinking. I can understand if the first time the car was not up to temperature, but my car was. For all pulls.

because engines aren't built for rwhp. the engines are all built the same.

but,

if you have an auto with 3.55's, you'll make diff rwhp than a car with 3.15

you'll also make less than a manual car,

and each manual car with different gears will dyno differently as well

each car with heavier wheels and tires will dyno different.

however, if you pull all those engines out of the cars, and put them on engine dyno's, they all should dyno almost identical

Vader 5.0 where did you get your dyno pulls done in Orlando ? I live in Titusville, but grew up in Orlando and work there over by UCF. I've been thinking of taking mine down to get it checked/baselined before I start doing the mods. Also what performance shops are you aware of around town. I have used Lamotta's in the past because they deal with Mustangs primarily, but there are supposed to be a few others now. One of my friends at work has a 2015 black GT with the PP, manual tranny and 3:73 gears. He has black rims on the car. You may have seen it around town.

Exactly. The engine makes the power, thus it makes sense to measure its output exactly where it puts it out, not some arbitrary point through a drive-train of unknown efficiency, like at the wheels, or the output of the transmission, input of the diff, etc.

Under the expectation that the whp be what Ford avertises, that means that the auto and manual variants (and even down to different wheel and brake setups, etc) would need different engine hp to achieve the same whp...

EDIT: For INDIVIDUALS concerned with how THEIR CAR performs, it makes sense to measure at the wheels, on THEIR car.
