    Very much so, the valvetrain would need to be very efficient

    Not with a blower sitting on top of it.

    Would be a good combination for floating valves.

    I wonder how many GT350 owners are out there that said "**** it, Im dropping a race prepped Coyote in this thing" when either their engine failed or wasn't making the power they wanted.

    A 2014 Cobra motor should fix it

    Doesn't have to be a positive displacement blower... A procharger would feast on anything at 9000 RPM.

    Now lets talk about the rods coming out and leaving a nice window in the block and overheating on the track....I like my 5.4 pretty well, sometimes I just go into the garage and look at it.....My wife calls my GT500 "the other woman"....so be it. TGIF oB

    It would also require some good computing power. It may not be a limit any more, but I was told that 5-6 years ago the stock ECUs couldn't keep up after something like 8k RPM.

    That wouldn't be too hard to remedy. Today's automobile ECUs use processor speeds from the mid-'90s. All they'd have to do is get with the times and problem solved. They'd just have to develop a way to keep the processors cool.

    Great article. You have to love engineers. Would love to come back in my next life and design engines.

    I was just speaking to a well known here and outside of SVTP Engine Builder/Racer who said he does build/balance 5.2 VooDoo with Coyote cranks. He said they actually perform very well. This all came from a conversation of a OEM sort of build to hold 1000hp. Aluminator was thrown into this conversation but him saying the 5.2 will handle a lil more since the block is built slightly difference with reinforced features. (not sleeved)

    I actually did this. i took out the fpc and put in the 5.2 cpc and cams. I run a f1a-94 procharger on it and figured the cpc would be a little more reliable. I upgraded the valve springs and set the redline at 9000 rpm, it will happily turn that high but really does not make any power pass 8200. Its made a best of 1130 whp but i have recently put a smaller grip pulley on it which should put it over 1200. I was having some belt slip issues around 7700.

    Hi, I agree that the valve-train was probably modeled to 9500rpm.

    If you think that engine ever had a prayer of being in a production, emissions passing car....

    What's the colloquialism i'm looking for...

    I have a bridge i'm looking to sell in Brooklyn

    It'll be in production next year with a TVS blower sitting on top of it.

    Is the bridge still for sale?

    A couple Detroit engineering friends told me about many of these negative things mentioned in the first post of this thread years ago. I still have my 93 coupe, and have had a handful of other Mustangs and Ford performance cars.

    When it was time to replace my 2011 GT with something else, though, I had a choice between the GT350R and ZL1 1LE.

    650hp + Multimatic DSSV + everything else vs square-peg/round-hole FPC 5.2 with 124 fewer horsepower and much less capability all-around. Equal levels of alcanterrorism.

    The choice was clear.

    I’m referring to a cpc 5.2 with a blower.

    I got an email highlighting it, or probably wouldn’t have seen it.

    ‘Twas a gut-punch indeed
