The ULTIMATE Coyote vs. LS3 thread.

Yup,

KJ's snow mobile > Coyote > LS3

 

[C.Evans]

Torque per Liter:

LS3 68.4
5.0 78.0

I FUCKING HATE THE DISPLACEMENT ARGUMENT.

Then why does the 5.0 produce so much for so little?

 

[Dasfinc]

What's really amazing IMO is that they got 170 more hp out of the original module motor from .4 liters and 2 more valves (along with head/cam changes).

LS motors went the other way and have squeezed nearly 200hp out of 1.3 liters and different head/cam selections. (LS1 to LS2 to LS7)

2 very different paths for similar results, really cool IMO.

gnarly ass heads.

 

[willizm]

I thought rating motors at HP/Liter was something honda guys do to feel a sense of relevance?


stir stir stir goes the pot.

 

[Yaj Yak]

its a weird thing to do. its like screaming yeah i am only working with 3 inches of thunder but i can hump like a banshee.

 

[C.Evans]

B16 putting the beat down on an LS3 is relevant.

 

[Dasfinc]

Like I already said, I swing off the LS motor, but the Coyote stock for stock is a far superior motor hands down IMO.

For Contrast

5.0 - 82.8 hp/liter
LS7 - 72.1 hp/liter
LS3 - 69.4 hp/liter
3V - 65.2 hp/liter

I just did the math for my old motor swapped civic, 142hp out of 1.8 liters:

78.9 hp/liter

KJ's snow mobile > Coyote > Dans crappy B18B1 > LS7 > LS3 > 3V.

 

[C.Evans]

LS3 heads are superior themselves!

 

[Primalzer]

The 5.0 in the Boss makes more power than the LS3

 

[C.Evans]

Im gonna put a Yamaha Vmax-4 motor in a stang.

fusion manual whaaat?

:naughty:

 

[Pressure Ratio]

Has a stock motor LS3 car gone 124 mph in the 1/4? At a street car race weight of 3500# or so. Shaun's car did it with the stock intake, air box, clutch, shifter and so on. Just mufflers and a tune. Plus light weight wheels and slicks.

This car added a Boss intake and went 10.88 @ 125 with minumal mods and 3550#.

 

[Pressure Ratio]

The reason the Coyote is rated at 412 hp is because of the tune. These cars have responded VERY well to reflashed PCMs. And they are still getting into the computer software. More will come out about these motors. I guarantee it. 124 mph @ 3550 is about 500 crank horse power. Ford holding back some?

 

[Yaj Yak]

no ls3 cars weigh that little

 

[Pressure Ratio]

^ hahaha true!

 

[C.Evans]

no ls3 cars weigh that little

What does a vette weigh?

 

[Eagle]

Allow me to catch up, just back from the gym.

I doubt that. i was at straightline about a month or so ago and saw a coyote with a rod thrown through the block that was only pushing 8psi with conservative timing with d1sc. It was a clean snap too. Txt me if you want more detail. Saw it first hand and i ain't lying

Pls send details.

Tune to change variable Cam Timing > Cam Swap

82.8 hp/liter > 69.4 hp/liter

:likes:

far superior ? what the fuck are you smoking to say "far superior" ?!

the coyote motor is far superior to a 2v. that's a better use of "far superior" captain excessive punctuation.

LS3 vette = 3200lbs

 

[Dasfinc]

Oooo More hp comparos

Boss Mustang - 8.18lbs per hp (3632lbs - 444hp)
Base Vette - 7.46lbs per hp (3208lbs - 430hp)

THIS is a comparison I'd like to see, Base Vette Vs. Boss mustang, similar price, similar power, similar markets.

 

[Primalzer]

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