^ yes
"factory" power bumps are much more meaningful than aftermarket gains because all the parameters changed (hardware or software) step up and work in unison

overboost, any comment on the forged internals theory?

lighter rotating mass... would seem to fit an 8hp bump

AzPete

Has there been any pictures from under the hood? If not, maybe a new intake....

MRGTX

Well...the Aluminator Forged motor is available for $7.5k or so...and figure $1k install (if you don't want to tear down a nealy brand new car)...and you could probably sell a low mileage '11/'12 Coyote for $3.5k...so $5500 upgrade? That might work out to be the same as the depreciation on our cars.

Overboost

It's not forged internals.

If this isn't a reply designed to start an internet toughguy argument I don't know what is.

Overboost

Hardly the case. Trying to keep speculation and misinformation from spreading.

AzPete

So.....tell the answer to the op and stop the games and speculation. Not like we are going to beat Ford out of 8 HP.

MRGTX

Privelaged information....

Overboost

I'll find out if its something that can be put out in the open. If nor, youll have to wait until someone gives me the ok. I'm not in the business of burning bridges.

Is the 2013 GT still OK to use 87 Octane? If not , a tweak to advance the base timing may explain it

And I am well aware the 11 & 12 5.0 is rated @ 412 on premium & that 87 octane drops it to 402 or so. Just saying that changing the margin, as requiring only 91 would allow, could result in a tweak to the tune to allow 420 with no change to hardware.

I thought I read somewhere that it had something to do with what they learned in making the Boss 302 engine. Maybe a revised intake or heads? I think Ford did that for one year with the 98 GT it had 10HP over the 96-97 models

825LTRGT

Oil squirters gone?

Revised windage tray?

TheReaper

It's the same engine that's in the 2011. The 8hp plus a few more have been there from the beginning.

97GT12

Exactly. With the lack of attention being called to some new feature or change strongly implies that someone sat down and did a statistical analysis and they decided they could safely bump up the rating by doing... nothing.

If they did something we would seeing words like improved, optimized, etc and then followed up by a part of the engine or programming. Marketeers can always spare a couple words to tell us why our previous model is out of date and we now need to get the new one. When they don't it speaks volumes.

BTW, official horsepower ratings are done on the special fuel used for development and emissions purposes. It's a more pure gasoline than we can buy retail and doesn't have ethanol or any other oxygenates in it.

Overboost

Ford certainly didn't pull a GM and re-certify their motor a few years later. There were internal changes to the motor, which came from the RoadRunner (Boss 302) motor development.

xlover

any word on when you can share the changes or when ford will?

not sure why ppl are speculating it is just a tune or a statistics adjustment you made it pretty clear before that there were internal changes

cdynaco

Ever heard of "trade secret"??

Why give GM & Chrylser any of Ford's competitive edge? They're already in a tizzy now. Let em stew.

PTRocks

Since I am free to speculate I'll go with modified exhaust ports for improved flow. Improvements in the CFD work done in the Boss resulted in a mod the engineers wouldn't have expected gains from.
