Different engine (2005 5.4) and tranny.......

 

And just for fun. Here's a 6.2 Raptor on 5star dyno and tuning.



292.4whp on 93 perf. tune for the 6.2
279.4whp on 93 stock for the 6.2

290.8whp on 93 perf. tune for the 5.0
Close to 270whp on stock tune for the 5.0


Would Ford be lowering the 5.0 number... Hum i don't know...

There's 51hp diffenrence between the 5.0 and 6.2, but only ''9hp'' on the dyno.

 

Different engine, not really. 2009 and 2010 only gain 10hp over the 2004-2008 5.4. Torque was the same at 365lb-ft. The only place you gain power was with E85.


But yes, the tranny do chance something. Enough to make the difference between the 5.0 and the 5.4... I don't know.

 

man that dyno rates the 411 hp 6.2 at 279 hp Thats like a 32% power loss... low reading dyno for sure!

 

And the 5.0 at 270.

But the 6.2 have the 35'' BFG AT. It's a Raptor.


Reading low for the Raptor, but way high for the 360hp 5.0...


I want to see an Ecoboost on 5star dyno.

 

Is it because of the 35" tires?

 

I thought the 4.10's would make up for the raptors tire difference. I think its rated for 15.8 in the 1/4 and weighs 6000lbs so it can't be losing too much more.

 

The dyno read low and Ford are lowering the 5.0 number to sell the Ecoboost

 

No sir. That is actually quite typical for an F150 4wd powertrian - ~30%. Well-known for years on this board.

Like i said before, those 5.0 are making more power then Ford say.


They're closer to 390hp/405lb-ft then 360hp/380lb-ft like Ford say.


With 5star tuning, they're make more torque with the 5.0 then the 6.2...

 

30+% seems high to me, but I could be wrong!

 

Not 'could be' ... you are.

Prepare to be edumacated

For you other folks - there is some info on dyno numbers in general, if yer interested - just FYI. Might help you put the numbers presented so far into some sort of perspective. Or not

Enjoy - I know I did

Any further questions - Mike's contact info is in my sig.

Well I stand corrected! Im used to atv world where 30% power train loss is a lot.

 

Don't care what the torque curve shows but I do know that that my 5.0 running 1900 rpms at 70 mph does not downshift on the very same hills that a 2009 with the 5.4 running 2000 rpm does.Don't know about other rpms but around 2000 rpm the 5.0 is stronger.I drove both running cruse control.Same hills and same speed.

 

Thats not a very good comparison. Cruising in overdrive, the torque converter is locked and the engine is making very little power anyways to save on fuel. Dyno pulls are done in 2nd or 3rd gear for this reason, the two engines probably produce similar torque at that RPM but only the dyno knows. That 2009 F150 might have been a lot heavier than the 5.0 truck, who knows there are so many variables to the equation.

And if the 5.0 really made 390/405 then the 6.2 is a complete waste of Ford's time seeing as the 6.2 makes horrible gas mileage and hurts the overall mileage rating of the company. A 6.2 on 31" tires would make excellent dyno numbers compared to the 5.0 engine.
