GM Engineer about the 350 fpc.

[svttim]

One of the GT4 racers had stated (Can’t remember where but I remember the question came up before) it was simply because with both motors HP restricted, the CPC motor made noticeably more useable torque below 3500rpms, with similar torque above 3500, making corner exits faster in the CPC motors. Limiting to 450hp kind of handicaps the voodoo more comparatively. I love my voodoo, but she’s gotta be rolling above 3500rpms to get around with any urgency.

I spoke to the racers themselves and was told the Voodoo was not necessary due to power restrictions and the fact they required more care. No need for a high strung race race motor when the CPC would do the job. Everyone forgets the Voodo won the championship its first year. Having driven the Ford performance school cars as many of us have, the Coyote felt like they pulled 2 plugs out, very slow in comparison to the track prepped GT350s.

Failure rates are no where close to 40%. Again, higher then the Coyote for Gen 1, Gen 2 so far is about the same as the Coyote. We see them because we are here and we hang together

Having owned (still own) 4.6 4v cars and built numerous 4.6 and coyotes.. I can tell you that the 4v 4.6 is a "cool" engine but it is no way...and I mean NO WAY any competition for a coyote.

My Gurney Motor 4.6 with Ford racing heads was close to a modded Coyote

this statement is so wrong i have to wonder if you're trolling.

my cobra was fast as hell and maybe faster than my new PP1 GT.
easily a 12 second car. its power hit like a sledgehammer vs the coyote building gradually to redline.

Yes the Cobra peak version of the 4.6 was similar in power to the 2011 V6 Mustang I owned. Fast car for sure.

Ford should have made the 320 HP version of the 4.6 the absolute minimum they would accept in a Mustang GT, not the one off special. Not when a 3.7 base V6 can make 305 HP with no trouble whatsoever. They should have been embarassed. Sorry not trolling. The 4.6 would be great for keeping a boat stationary, but it's not a great engine for a sporty vehicle.

dude tuned bolt on cobras make 320 at the wheels all day long. thats hp and torque... and it makes the torque everywhere.... 20 years ago... and you're comparing a car released ten years after it went the way of the buffalo?

you are out of your depth.

1999 Cobra great car, tested by C&D 5.5 seconds 0-60.

2011 Mustang with a V6 tested by Motor Trend 5.1 seconds 0-60.

There's nothing new about understanding how to make power. It just takes enough air flow. Yes, modern tools can develop new parts more quickly and easily, but people were making well over 400 HP with pushrod 302 engines in the 80s. The time argument doesn't fly. Ford knew how to make the power, they just chose not to.

that's just dumb. do you even remember the late 90's-2000's or where you still riding a bike?

 

[Hack]

that's just dumb. lemme guess, late teens early 20's?

No I'm an old fool who has driven many slow 80s Mustangs but never liked the 4.6. I didn't buy any Mustangs made between 1990 and 2011. I never liked that engine.

ah well prejudice would explain the completely insane things you're saying.

Like the 4.6 doesn't make much power and it is similar in power to ordinary V6 engines? Hah! Anyone can see that just by reading about the engines. The numbers don't lie. And don't forget, you are comparing the very best extra special 4.6 to V6 engines.

You definitely don't want to compare the ordinary 4.6 that most people had to live with to anything bigger than a turbo 4.

I don't remember them that well, but I was out of college and working by that time.

Oh they can be made better, for sure! Takes something more than pump gas to get one to out-perform a stock coyote. It's just that the coyote has a lot more grunt all around, right out of the box.

 

[Inthehighdesert]

Why so sensitive about the 4.6. I wasn’t a fan of them either, but we can all have our preference’s. It’s a pretty uphill battle trying to justify how the 4.6 compares to the coyote. But by all means carry on. It’s entertaining. All this from me looking for the GM Engineer quote.

well thank you for confessing your ignorance and partiality to the 302's that randomly crack in half.

so tell me this, genius, what makes the coyotes vastly superior to the 4.6's?

Mine was on pump gas. The extra cubic inches was key along with cams and heads. Mine was a 3 valve mind you.

The 4.6 Cobra motor was great for its time. It is the grandfather of the Coyote

 

[svttim]

How did this turn into a 4.6 vs Coyote thread? The 4.6 3 valves in stock form were nothing to get excited about. IMHO even though they outflowed the DOHC I think it was a step backwards (and I raced one)
