2011 Ford Edge Sport finally dyno'ed ... not impressed with results

[scuubydoo3]

Alright everyone... Everyone has been asking for it.

 

I have a 2011 Ford Edge Sport. I've modded it withe the Prozenmotorsports Cold Air Intake, a Magna Flow exhaust, and a custom tuner.

 

I had them do an initial dyno to see where the car is at on horsepower. With a cold run, my 2011 Ford Edge Sport with the Cold Air Intake and Magna Flow exhaust was sitting at just 185HP at the wheels . I was really shocked with the result so several technicians and I checked all the connections, and made sure the wheels were sitting on the rollers correctly. We ran another dyno test and with the engine warm this time the result posted 183.21HP at the wheels. Again with only the CAI and Magna Flow exhaust.

The technician did an initial tune and ran the dyno which you can see the results in the last picture. The picture shows the initial run, the second run is after the first tune and the final run is the final tune.

After the first tune, he tuned it up some more. Which gave me the final result of 221.7HP at the wheels.

I know you can normally expect a 20% loss of horsepower when going from the engine to wheels. They also say that the Edge Sport loses even more horsepower with the 22in rims. Considering all those factors these results are saying that the Edge Sport is losing 120HP from engine to wheels. And thats with a modded CAI and exhaust. Even after custom tuning the engine with those two mods included, the results are telling me that the Edge Sport is running 28% less HP at the wheels from the engine.

I've included pictures of the results. The only result that I forgot to print of was the initial result (185HP). I'll try calling the dyno shop to see if they still have it saved and print it off for me. The second and last picture still shows the result differences between the first and last run though.

The third picture shows the air to fuel ratio result. Notice on the first run (before the tune) how it drops dramatically at about 4200 rpm's. The tune quickly fixed it where it stays constant through acceleration.

 

Now, I'm not a mechanic and almost all of this was explained to me while he was doing the tests.

There's lots of mixed feelings on these forums whether someone should do mods to their vehicle. I chose to do this and I'm capable of putting my PCM back to stock settings at any point that I feel i'm not satisfied with the changes.

Thanks and I hope this answers alot of peoples questions.

I'd try another dyno. That sounds way too low even with larger wheels.

This was an all-wheel dyno. We checked everything about it after the first run because I thought the same thing. The dyno is used frequently everyday and everyone elses results came out correctly.

 

Results are the results

Go to the dealership and test drive another Sport to see if it has more power stock?

The car still has alot of power. After I put a few miles on it and let the PCM learn the system again, the tuned settings will kick in and it will be even quicker (the 221.7HP).

I'm shocked that with the amount of power that it had before it was tuned that it only came out to 185HP at the wheels.

[Loosecannon]

Now wait a sec... why is everyone surprised that it's only putting down 221 to the TIRES...? The Edge doesn't make over 300 to begin with? Even the new Edge Sport is only putting out 305, and thats at the ENGINE, not the wheels. Completely different ball game when your talking horse power at the wheels. I think 221 is a very respectable number.

My 2006 GTO with a ton of mods, made 550 at the engine, and put down 450 at the wheels... same thing, lost 100 HP thru the crank, and drive line etc,.. Thats just the way it goes.

221 is the horsepower its putting out after a custom tune, CAI, and after-market exhaust. After all those mods it isnt putting out the 20% horsepower expected it should put out at the wheels when it's even stock. Heck even without the custom tune job the orsepower was at a 28% loss at the wheels.

[mrdave]

The only thing you should take away from your dyno runs is that you increased your HP by about 19%, which is pretty darn good. Unless the dyno has been calibrated recently those numbers are not much more than rough estimates.

[Loosecannon]

I've never considered a simple exhaust, CAI and a tune a high horsepower maker. I think your ahead of the curve here.

I wasn't considering those three mods to increase the horsepower dramatically either. I was just trying to state that with the CAI and exhaust that the car is still not even putting out the horsepower at the wheels that is expected in the 20% loss from engine to wheel ratio. Than with the tune put into that equation that the car still didnt come back up to the expected 20% loss in horsepower from engine to wheel.

I agree that those mods only increase the horsepower slightly and about 19-20% increase in horsepower is ok with me. With the 20% expected loss at the wheels, I was just expecting it to be around 264HP after mods instead of 221.

[Chingon]

I'm not familiar with the Sport engines, but it seems that nowadays CAI and exhaust are not guaranteed power adders. In some cases, you can actually lose power. It would have been nice to dyno the car stock first.

 

What elevation are you at? Up here we're a mile high, so for NA engines you lose an additional 20%. AWD dynos are probably used to dealing with turbo cars, which lose less hp at altitude (comparatively speaking). That would put your 185hp up around 235hp corrected for SAE...

I bought the car and live in South Texas but I'm currently in San Diego right now on business. The stock air box is back home sitting in my game room. Yeah, it would've been nice to have a stock dyno result but that wasnt possible.

So regardless which location I'm at, the elevation is at sea level. The dyno I used was loaded. Meaning, it simulated actual road usage instead of being a free load. That makes the result even more accurate.

Besides the car not being up to what Ford is claiming the only other thing that I can think of is that the dyno was inaccurate. I am currently trying to find another four-wheel dyno here to have a comparative result.

I can't find anything on the internet to informatively say how much HP is loss for bigger wheels. Weight of the vehicle is a factor along with the size of the wheels.

[Chingon]

I'm sure the HP ratings are fairly accurate from Ford, but obviously each engine varies +/-. I still think you could do a quick 0-60mph sprint with someone timing you, then test drive a new one and do the same thing on the same road. If yours is faster, then it's probably the dyno. At the end of the day, the only measure of performance is track time...

[cal3thousand]

I'm not surprised at all.

 

Those 22" wheels not only weigh about 25-30 lbs heavier each, but the moment of inertia has changed as well. Think about strapping a 25 lb. dumbbell to a 18" chrome clad and what kind of effect that would have.

 

 

NOW think about that 25lb. weight spread out over the whole rim versus stuck on just the hub. (eg 5 x 5lb weights all around the barrel)... The rotational inertia that the engine needs to overcome before your wheels start to move is MASSIVE.

 

It explains why the Sport is NOT the quickest Edge from factory.

 

 

EDIT: BTW thanks for posting this. Very interesting to know that 40 ponies can be squeezed out of the 3.7L ... I wonder what kind of gains can be made with the 3.5L

The size of the wheel should make no difference on the dyno, though it will make a difference in acceleration times.

 

What this result tells me is that your CAI and exhaust are doing more harm than good. If you can get that much improvement from some simple tuning, then it means it was really screwed up to start with.

Are you kidding?

 

 

On a "roll-on" type dyno it sure makes a difference. Again, I will say... Rotational Interia. Explain that one.

 

Strap a 25 lb weight to each wheel the next time you dyno it if you think it won't make difference.

That's why I did mention that the dyno I used was a loaded dyno. It simulates the actual friction a car would encounter while driving on a normal road. They do have other dyno that are "free load" that doesn't simulate that experience for the car. Those kind of dynos won't give you an accurate result.

 

Cal ..... I might have some free time after Tuesday of next week if you want to get together. Test drive each vehicle to see if there is a considerable difference. I'm in San Diego til next Friday than I'm back to Texas. It would be interesting to see the differences between the two cars now. Send me a private message if your interested.

Ahhh that makes perfect sense that you used a basically what's called a Mustang Dyno, those numbers will ALWAYS be lower than a dynojet which is basically unloaded. Most dynos are of the dynojet type, not a lot of Mustang dyno's out there. To give an example my old Roush on a Mustang Dyno only put down about 345rwhp, on a dynojet it put down over 380HP. The problem with Mustang dyno's is that if you don't get the loading right and the weight right the numbers can be all over the place, just change the weight on it and you'll get a totally different number. I've done so many dyno runs in other cars I've lost count. Me personally the Dynojet is pretty much the standard for tuning. it uses the standard weighted drum and calculates the HP based on the math and not on loaded weights. They can "unload" the dyno so it acts like a dyno jet and you'll see a higher number.

 

Also the AWD will absolutely eat up more power and those numbers will be about 10% or more lower than the FWD.

 

Now the power gains you got on an NA motor are actually quite impressive and on par with what the Mustang V6 guys are getting with similar mods. A 35AWHP increase is actually fantastic and should put the your Edge at about 350-360HP at the crank. My guess is it should put down about 270-280AWHP on a Dynojet (or more).

 

I'm going to do a Dynojet run on mine totally stock, then I'll do a tuned/cai run and see the difference (I have a FWD). I may do exhaust as long as it doesn't freakin drone....

As far as I can remember it was an AW unloaded dyno. Not a dyno for a mustang. I have been thinking about having it done on a different dyno to see if there is a difference. Let me know what your results are with FWD.

Mustang is actually the brand of Dyno. It's a loaded system that allows you to plug in different weight for the vehicle and and it applies more resistance to the rollers thereby changing the HP figures. My guess for my FWD would be about 240-250'fwhp. With tune/intake/exhaust should pick up 25-30fwhp. Similar 2011 V6 Stangs are making 290'ish rwhp same mods.

 

I'll get the Dyno done in the coming weeks and then again with mods so we shall see...

Those number sound dead on, for a Mustnag dyno. If dyno numbers are what you seek, find a dynojet.

[Edgieguy]

This actually gives me hope that the procharger's 175HP gain wont tear apart the Edge. Im going to speak with my mechanic and have this info relayed to them to see what the engineer we were working with thinks. If parasitic power loss is 90-100 then the 75hp gain should be absorbed by the vehicle without much strengthening of other components required.
