Is this possibly possible? It be like a Coyote killer? Any one know if this is possible? I'm still learning all this Mustang lingo/language. Any input??

Thank again!!

How would turning it into a coyote make it a coyote killer?

Boomer

I'm noticing a trend with all your threads.
You have a hard on for 5L.

If it's power you want, just strap on a S/C and call it a day.
If you want a 5L, go get a 5L

Killer Coyote lol, I guess that does sound better.

Actually I'm confused, so my engine is a sohc, and I'm sure I could bore it out to a 5.0.....at the right shop, wouldn't that be different then a Pushrod 5.0?

Hey its a mustang forum to get educated what fun is it if your not asking questions.

Before the Coyote engine came out, hot rodders were throwing all types of superchargers on the SOHC 3 valve engine and making insane power levels that would run circles around a stock coyote engine. Just go to a library and read articles from Muscle Mustangs & Fords magazine from 2006 to 2012 and you will find articles about building horsepower from the SOHC 3V engine . You can go to forums about the modular engines and get all kinds of information about producing incredible horsepower from the 4.6 SOHC 3V.

Thanks for the info!!

A 5.0 is not a 'coyote' engine necessarily...

steven46746

I didn't mean literally, just going along with OP's train of thought.

2005GeeTee

Oh so maybe the other way originally sounded better, a 5.0 sohc is not a Coyote so if it was made into a bad a.... Engine it would be a Coyote killer.

As stated before, a supercharger is the most cost effective solution to make 5.0 power or more.

True true Whipple Whipple Whipple!! Dream dream dream!!

The Saleen Parnelli Jones had a normally aspirated 5.0L 3v engine that made about as much horsepower as the Coyote 5.0.

The 3v will never make more power than an equally built Coyote, due to the Coyote being a 4 valve head and dual cams allowing the head to both breath better and have more control over the cams. You can build a 3v to 5.3L, 326 ci, with a stroker kit and the new Boss FRPP engine block and it will be a killer combination but you wouldn't beat an equally built Coyoto based build.

cdynaco

I understand what you are saying. And with the advent of variable cam timing, going back to DOHC has given more control throughout the power band from idle to WOT.

However - the nagging thought in my mind is:
a) the DOHC has the parasitic drag of 2 more cams, 8 more (exhaust) valve springs; and
b) what power do you really gain from 16 small exhaust valves over the 3V's 8 large exhaust valves when port and polish on the 3V heads would be for max breathing - plus I believe equal length long tube headers should negate any exhaust breathing differences; and
c) really the TiVCT variable cam timing on the DOHC only helps for improved low end torque and emissions (while retaining maximum performance at WOT) when you consider the SOHC 3V build would include high performance cams for max valve timing overlap at WOT anyway. Most builds use phase limiters to help retain some of the low end torque from VCT function, but the cams would be for high performance at WOT.

Also keep in mind, the OP is referring to a custom build on an SOHC 3V to bring the displacement up to 5.0L compared to the stock Coyote 5.0, as I understand it. So the 3V would need to spin up to 7k redline. Which shouldn't be too difficult since Ford took redline from 6250 on the GT to 6500 on Bullitt with the only change being the harmonic balancer. Better valve springs may be involved for that last 500rpm.

Vermillion06

The PJ motor was built pretty much that way; they took the 4.6 3v and and added a stroker crank, pistons, and rods, hotter cams (still emissions legal) , a valve spring upgrade and cleaned up the heads around the valves a little. Everything else was stock. They got 400 hp. Probably could've gotten a lot more if they weren't trying to meet emission standards.

Thanks for posting. That was an engine benchmark for a cool build-up of the 4.6L 3V to 5.0L. I love that engine and the car that is powered by it!

To the OP - you can make anything you want if you have enough money

Boomer

Keeping in mind the coyote is the new hotness from Ford and is relatively new compared to the last of the 4.6 mod motors.

It's come a long way, but the coyote is in it's first gen and it'll only get better.

cdynaco

Why/how?

All "tricks" can be applied to all engine builds not just the Coyote. Its only 21 cubes larger than the 281.

cdynaco

Thanx!
