The ULTIMATE Coyote vs. LS3 thread.

[Dasfinc]

You got it the wrong way around, that is pounds PER HP

Owned myself , I'd still like to see the comparison.

Coyote Engine - Based on a motor first put into production in 1992 that had 230hp, and now puts out 414hp. It uses 5 liters of displacement (the area that the piston essentially travels through) and lots of technical wizardry to make power

LS3 - Based on a motor first put into production in 1997 that had 310hp, and now puts out 430hp. It uses 6.2 liters of displacement to make power.

Watch out. He is going to trick you!

Tune to change variable Cam Timing > Cam Swap

82.8 hp/liter > 69.4 hp/liter

HP/L & HP/ci means absolutely nothing in the real world.

Okay.... that makes sense. I feel smarter. :hsughwiggle:

 

[Typhoon]

no ls3 cars weigh that little

Agreed. I would also argue a Mustang is better setup than any vette from the factory for DRAG RACING. If we're talking motors the only way to subjectively compare them would be to have both in the same chassis.

 

[Yaj Yak]

someone should do that. each through a th400 or something.

 

[C.Evans]

HP/L & HP/ci means absolutely nothing in the real world.

A top fuel dragster makes 16 HP/ci and 1000 hp per cylinder. If that didnt mean anything it wouldnt do 300 mph in the 1/4.

Someone get me every thing I need to do this. I will take care of the rest.

It still means absolutely jack shit. What matters is that when it pulls up to the starting line is has 8500+ HP. It makes no difference whether that comes from 1 liter or 10.

 

[Pressure Ratio]

Are you assuming that no matter what the displacement the power production is exactly the same?

get out of here with your ricer math! What he was trying to say is something along the lines of this "i dont care if your 5.0 makes 82.80 hp per liter,Im gonna use my with my bigger, badder, more powerful 7.0l 505hp 427CI LS7 PUSHROD, to F up that junk ass mustang six ways from sunday!

 

[Typhoon]

Are you assuming that no matter what the displacement the power production is exactly the same?

Yes. According to his statement if they didn't make 16hp/ci then they wouldnt go 300mph. What if the size of that motor went to 800ci instead of 500ci yet they both make the same power? HP/ci goes down but they will still go down the track the same. (This is course assuming the physical size of the motor and weight stay the same). At the end of the day it just matters how many horses you have.

 

[Pressure Ratio]

I thought you were saying no matter what the displacement 8500 hp is 8500 hp. That is not the case. OK Gotcha!

 

[OffshoreDrilling]

id take the LS3 simply for the aftermarket. Id love to own a fox body with a nice little procharged coyote in it though

 

[Pressure Ratio]

Nom!

Stock motor, tune (not a dyno tune), T56, 3.73 gears (needs 4.10s as it just shifts into 4th right before the traps), long tube headers and 3" exhaust. 11.14 @ 124 so far.

I would slap a Vortech on this and have a nice driver.

 

[C.Evans]

Here was how I am thinking... 8000 hp in a 1 liter engine is far superior to 8000 in a 10 liter engine. It takes more to get power out of a smaller engine N/A. This is exactly the case with the 5.0 and LS3.

 

[Eagle]

Wow Pratt... that didn't take long for that dude to accomplish at all! Awesome build.

Ask yourself this......How would it make power? What kind pf power curve would one have versus the other? What kind of rpm would the smaller motor need to make the same peak power? And so on.

 

[OffshoreDrilling]

totally different technology between the two motors. Overhead cam vs. pushrod.

FRPP sells a conversion kit including simple wiring harness, relays and PCM. Kurgan Motorsports took a running 90s couple with a pushrod 5.0 and got a running coyote 5.0 motor in the car in under 5 hours. I think there was three guys. This was done at the Ford show in Carlisle Pa. Great kit for sure.

I am just talking HP versus cubic inches.



But yes. A coyote versus LS3 is quite different.
