New member here - I am trying to figure out what the increase in HP and TQ are for the Superchips 87 Tune for a stock 2010 F150 5.4. In one link on this forum found here:
https://www.f150online.com/forums/ch...-f150-v8s.html

It shows that RWHP for the 5.4 and 87 tune is 271 and TQ is 331.

However, on a newer link found here:
https://www.f150online.com/forums/ch...unes-f150.html

The graph (comparing with and without the CAI) for a 5.4 87 tune before the K&N CAI shows HP 268 and TQ 313.

So which is it? Perhaps I am interpreting something wrong...

 

Dyno numbers are not perfect....
There are a lot of factors that can determine the differences.....

 

Those numbers seem far too high for a canned tune. (if that is what they are refering to)
Example on a 2004

1) 5.4 3v 300hp stock at crank, 228 at the rear wheels
2) 5.4 3v 250-260 rear wheels with custom tuning and
AF1 intake.

Just an example.

Not saying the SC tuner is a bad option, however I find that info hard to believe.

 

Woops, wrong link! :o

 

I emailed the folks at SuperChips last week and have yet to hear back from them what the "official" HP and TQ ratings are given the discrepancy.

 

Might inquire here:

I just now today noticed that the link I had posted was not related to this discussion. I guess I thought I had copied it and when I pasted here, it pasted what was copied before ..... like I missed the link I was trying to post here.

Anyway, this one is correct.

Sorry!

 

Those numbers should be about correct... You have to realize the 09/10 5.4 has 320hp to the crank, not 300hp. And 228rwhp seems far too low, that would mean a ~32% drivetrain loss. Usually a vehicle will have 15%-20% drivetrain loss.

 

Hi.

Sorry Mr. OX ... Marc's numbers are correct - and yes, there is actually that much driveline loss in these trucks - even 09/10's with a 6R80.

Example: 2009 F50 5.4L 3V:



Above is excerpted from: https://www.f150online.com/forums/20...ts-2009-a.html

So - accounting for variations - dyno, operatror technique, environmental conditions, engine variations, stock PCM calibrations (can make a huge diference) etc, etc, the numbers Marc posted were actually quite normal. Some of these trucks have shown even lower stock numbers - 210-220 HP @ the crank. Yep - it can suck.

Just FYI - Marc worked with Troyer Performance for several years and has seen more F150's on the Dynojet than most of us will in several lifetimes. I think you can rely on his experience and accuracy here. In fact, if I'm not mistaken, those were figures from his own truck's pulls, stock & tuned, lol.

Oh yeah, BTW, for '09/'10's, it's 310HP stock @ the crank on 87 octane fuel (320 on E85 only) : http://www.fordf150.net/2009/2009-fo...ifications.php.

Wow thats disappointing. My SS Camaro had about a 16.5% drivetrain loss, I wouldnt have thought my next vehicle would half been half as proficient in putting power to the ground!! Im guessing the less then stellar shifts in the transmission may account for some of that loss. I wonder if swapping out the tranny fluid and gear oils with something like Amsoil or Royal Purple syn's would help at all...

 

Not all manufacturers rate their engines at their true rating. Im assuming you had a camaro with a LS1 engine, if so they were rated around 300 hp and they actually put down around 300 to the wheels stock. Same principal applies to the 03-04 Cobras, rated at 380 or 390 and would put that much down to the wheels. Dont get caught up in the numbers game, they are just that........ numbers. Ive seen some cars with less hp beat up on cars with more hp. You have your dyno queens and you have your true track cars. Autos eat up alot of power but if your into performance you cant beat todays transmissions, well except for the crap trans tune Ford gave our trucks. Find a good tuner that can really wake the trans up!!
