On a Mustang Dyno

254.1 rwhp @ 5500rpm
274.8 rwtq @ 3750rpm

 

just me or are those numbers low? under 300 at the crank? that doesnt seem right

 

Despite the odd numbers, that torque curve is amazlying flat.

 

Mustang Dynoes always have lower numbers. This will probably be around 275ish to the wheels on a regular Dynojet Dyno.

 

thats the only thing im not really familiar with....whats the difference between the mustang and the dynojet? which is more accurate?

 

i guess we have to realize that this is a brand new mustang as well....things obviously havent set in and it will pick up some hp once they do

 

Well from what I've always read in 5.0 mustang mag and other mustang magazines, the "mustang dynos" are always notoriously a bit low vs other brand of dynos... So will be interesting to cross reference this with a few other dyno runs...

 

so its confirmed that this is a mustang dyno? ...i have been to the livernois shop and it is beautiful...such nice people. The owner of the company is one of the nicest people ive ever met.

 

Yes its confirmed, considering the dyno sheet says "mustang dyno" at the top. Mustang dynos measure the horsepower under load, so the rollers have resistance against the car when they are spinning.. A Dynojet does not, which is why it generally has higher numbers than the mustang dyno.

 

"The Dynojet will generally put down another 10-15% more whp than a Mustang Dyno according to Greg at Speedworks"


Oh ok...i didnt really look at the top of the sheet...thanks for pointing that out

somethings messed up with those calculations... a mustang dyno is a better representation of real world driving correct?

 

so its making about 290 hp, give it a few weeks and an oil change and see what it makes, the engine needs to loosen up a bit.

 

nice curve, or lack of it. Power when you need it

 

well for those of us that live by the rules of torque hi and shift low this simply wont do hahaha

 

Yes Mustang dynos put in the weight of the car which changes the accleration drums resistance. They are great to tune on since that is what you will be pushing on the street. A guy a work adds parts and tunes his Lightning on the Mustang dyno then goes to a dynojet for bragging rights. Gets about 10% more on the Dyno Jet consistently. One of the Mustang Mags is doing a multipart review of Multiple dynoes. Also he doesn't appear to have a big shop fan running that will effect the hp also.

 

exactly, it makes for much more accurate tunes and is much 'safer' to tune on when pushing to extremes. All other cars are judged on the 'standard' dynojet, so when you compare apples for apples you use those numbers.

 

Okay guys, before anybody panics, where does it say automatic or stick?
What are we dealing with here?

 

Look at the last pic! There is the answer.

 

Those hp and tq curves look AMAZING!!!! The torque curve is practically a horizontal line. All of the torque is almost available at 1000rpm. The hp curve even looks better than most cars torque curves. Very nice. Lots of power everywhere.....

 

HELLO, MCFLY

 

On a different note, I've been looking for a good picture of a medium parchment interior with IUP. I was afraid the aluminum and the tan color might look a little weird together, but this looks great.
