My car had recently gone into the shop for parts install and tune. On the Mustang Dyno at CIN Motorsports I was producing 305HP and 243 TQ at the end of the process.

Does anyone else have such a gap in their Horsepower and Torque? Or what did you do to close the gap/increase the Torque?

 

HP is a function of torque:

HP = Tq * RPM/5252

Without knowing the specific RPM you're making the comparison at, there's no way to comment on the "gap" you're referring to. How about posting the dyno sheet?

 

HP = (torque X RPM)/5250

So... You can't change torque without changing HP. They aren't independent.


EDIT:
Wow - got beat. Nice one Dave

 

The large gap simply means you make a lot of torque on the high end.

 

The entire reason I ask is because I was looking at a friends car, learning it like I had to learn mine. Research. And I found that her car produced more TQ than HP. It's a 99 Mustang V6. I know I know..american is built different than import, but it still threw me off.

 

actually they both interact and can be used to calculate each other but hp is an actual measurement as well it is simply a measurement over time or simpler terms work potential vs torque is an instant measurement or force measurement.
1 hp= the force it requires to move 550 pounds 1 foot in once second. this is how dynos like dynojet actually measure then the torque is the calculated portion.

every single engine will be different it is a function of various factors primarily VE, stroke(longer arm means more force on the fulcrum), and camshafts(bigger cams mean larger opening for longer to support high rpm power but it looses velocity down low where peak torque is made since there isnt a restriction to speed up the air essentially). what is done to your engine? without specifics we have zero possible ways to assist you in increasing torque

 

If you want to make more torque, or get it closer to your HP number, I suggest an LS swap, and a couple turbos

 

Want more TQ? Get a single turbo kit and small exhaust setup!

 

Injin long tube intakes, Dc Sports ceramic headers, Motordyne ART pipes, TDX2, and Quaife LSD. UpRev tuned.
Don't get me wrong, I love the gains that have been shown! And eventually I will be getting turbos and building the motor. 'till that day, the next mod I'm doing is paying her off!

 

not much you can do at this point to equalize the torque then, might pick up a tiny amount of torque with small cams but not going to be worth it and probably going to increase the gap, torque is all but a useless measurement anyway the only time it matters is when the car launchs since its work potential anything past launch the hp is what matters since thats the actual measurement of work being done.

 

Haha that's what i have to continuously explain to a friend of mine. How anything else I do won't really affect much, and won't truly be worth the money. I thought of getting larger fuel pump and injectors along with some cams, but all of that will come with the rebuild kit from GTM.
Can always go with a lighter flywheel/clutch combo and some tighter gears for a stronger launch..but I like the gearing now. And my clutch/flywheel slips only a little.

 

how do you measure slipping "only a little" if its slipping you need a new clutch bottom line since it will only get worse. as the compound heats up it looses friction coefficient so the longer you drive the more it will slip. if its only slipping a little cold that means its slipping alot hot.

no idea what your talking about with tighter gears

 

I mean go up in the gearing ratio. To like 4.1 or 3.9 gearing. And I know I'll have to replace the clutch/flywheel soon. Money and time are a factor right now though.
