Speaks to a few differences

Interesting. Phosphate coating are used to improve cold start lubrication not for thermal protection.

Since those figures are based upon using premium fuel, their 'tweaking' was...miniscule. I know that I don't have to due anything to my '11 to put out more than those 'official' figures. The stock figures on my '11 using a load bearing dyno, when all things are said and done, equate to +or- 406BHP using 87 octane. I have never dynoed stock on premium but, I'm willing to bet it would reach at least 420. As it stands now, with a 91 octane performance tune, it puts out 440+BHP. That being said and with what the article was saying about manufacturers farting around with the numbers, I'm sure the 420 estimate is low balled.

I don't know if anyone's seen this, but this is the new '13 Supercharged Coyote Cobra Jet. It shows using 12mm head bolts, which leads me to believe it is using the '12-older block.

This is the n/a Coyote Cobra Jet:

Thanks for that! But, for 25 large, I'll keep my weenie and enemic Coyote.

I think they do that so no one buys one and it stays mostly vobra jet exclusive

I don't think so. Look at all that went into that motor. That's everything you would need minus fuel pumps to have a wicked power plant.

The new '13's run 5W-50!!!

Hmmmmm..........either CURES or MASKS the oil burning of the pre-13's!!!

 

[Mystickeith50]

WTF wow....I guess Im not crazy for never putting 5w-20 in mine.

 

[VA Raptor]

It looks like they're recommending full synthetic now too.

 

[Rob72]

I wonder if the GT500 is still using 5W50 with their new piston squirters?

5w-50 is used in the 2012 Boss 302S motor.

Edit: 5w-50 is used in all current model Boss 302 motors.

 

[UltraKla$$ic]

So '13GT = Boss 302 motor!!!!

that would be a kick in the dick...for all us 11-12 owners wouldn't it?

So true. I was just trying to convince my wife we need to Coyote swap her '77 Ford F150. She could have mine and I'll get a Boss motor......she didn't go for it. LOL

So was the 5w20 used because of the oil cooling jets?

5W20's been used for quite a while...at least as far back as i can remember. my first mustang, an 01 GT used 5/20

 

[Mystickeith50]

5-20 is used for CAFE regs....they will never be able to convince me otherwise. Also to go along with this assumption, yet totally unrelated, I recently bought my wife a new 2012 hynduai sonata 2.0 turbo limited. I just did the first oil change and in the manual it says they rec using for proper lubrication a synthetic 5-30, although they note underneath that if you want a little better mpg to use the 5-20. So they are basically saying we want u to use 5-30 but 5-20 will do if your willing to not properly lube the engine in return for better mpg. Basically what ford and every other CAFE inspired oil required car does lol.

Makes scense. Even my neighbors 2011 V6 camaro says on the oil cap, "use 5w30".

A guy on another site says the 13 manual still say's to use 5w20.
Looks like some one may be pulling a fast one...
