Coyote CJ Carb motor 590 engine hp

Pretty interesting, especially when they are talking cam specs and advancing / retarding the intake and exhaust. 12:1 compression. Also note what they did with the cam followers.

The only thing I was thinking, however, is can't they spin this thing higher? I am guessing because they wanted it fully street able. Just think if they went with a bigger cam and titanium valves. My 598 I am building will be turning 8000 also. The video is good but if you read the article, it even has more info.

"Once our heads had made their way through the Livernois CNC program, they’re capable of flowing an incredible 347.1 cfm at .700 lift on the intake side, and 226.3 cfm at .700 lift on the exhaust side. This is an increase of 37.1 cfm on the intake side over stock and 36.4 cfm on the exhaust ports."

^^that is quite a bit better then the ford racing stage 3s.

That's an impressive motor! don't think you can fit that under a stock hood...

That is awesome and impressive. I always love to see what can be accomplished with unlimited resources and money.

cool stroy


just gotta wonder why you'd do it

 

[psfracer]

Because they don't own a laptop or have a tuner?



But with the heads flowing that much at .700 lift, I was just wondering why the .500 lift cam? But once again, I guess because they were building a street able version I guess.

I would go much bigger on both duration and lift, and spin that thing to 9000.

Clearance on the head is a limitation. Don't know how far it can be modified.

We just did a coyote in house for a customer. Not the most exotic stuff and it made 625@8200! Who want's to pony up for a all out max effort n/a Coyote?

I donate the car to put it in!

You mean piston to valve clearance?

What do you think the Coyote is capable of HP/CI if you had free reign to take advantage of everything?

1 million HORSEPOWERS!!! mwahahahah

No, clearance with the rocker assembly. The Boss has more cut into the head vs stock, but 13mm/.512 lift seems to be close to the upper limit without further modification. Here is a pic of a cut head for reference.

We are pretty confident we can make 750-800 n/a at big rpm.

Would need alot of stickers for that!

9000, 10,000???????

 

[go302]

1,000,000 rpm

 

[Livernois Motorsports]

9-10K!

 

[Mystickeith50]

9-10K!

Wow that would be insane and awesome.

 

[Bobby]

Damn i would love to see that

I agree that with those flow numbers, 750 hp is obtainable. But as we know, flow numbers don't mean everything. If lift is limited due to head design, mid lift flow performance is going to be really important as is intake manifold design.
