15 GT doing work as usual
I've never seen hp/ci win a race
I can agree with that.
HP/CI is cool, it's just not a figure that is easily compared from one engine to another. A 4v DOHC engine with vtc and such *should* be more efficient than a 2v/singlecam/pushrod engine in power per liter. However, it's necessarily bigger and heavier at the exact same displacement, so you typically end up with a smaller displacement DOHC engine vs a larger displacement pushrod engine when you're comparing these two engines that will fit in the same car/engine bay.
This is why, at least in my mind, a more "functional" comparison would be power per pound (weight of engine) or power per cubic inch (volume of space the engine takes up in the engine bay).
Either way, 600whp in a 5.0 is badass. I'd love to see more details and the dyno readout.

If HP/CI was a measure that mattered in racing, we'd all be using tiny inline 6 and 4s from across the pond - not Coyotes. I was just trying to state what would be a more functional measurement of an engine's performance if you need to measure "hp per something."
Just about every Coyote car that comes through the install shop seems to be getting a power adder. Most of the N/A guys are road racers and they have a big advantage with the wide power band of the Coyote in that type of racing 3800-8800 wet sump.
head cam header ls7 makes 610-630rwhp 515-535 lbs 4000-7200 427cui
prepped Coyote makes 575-600rwhp 420-450 lbs 3800-8800 314cui
We have a whole staff of people here that are happy to help and will do our best to increase your customer experience.
Typically, our Powerstorm Coyote Piston/Rod Sets come in 10:1 and 11.5:1 compressions, and as for pricing they are around $1900. We can engineer a set for you depending upon your power level and application, if necessary as well! We have designed drag race, road race and extreme MPH variants of our pistons so we are more than capable of helping you with whatever it is that you need!

I'm curious... You state a much wider usable range for the Coyote than LS7, but could you explain why the peak torque is so low for the Coyote if it's making lots of usable power at 3800 RPMs? I guess what I'm saying is that, judging by the peak torque numbers and max power, it seems your Coyote example would be more of a 5000-8800 setup. Could you post some dyno graphs of some high power "prepped" coyotes? I'd like to compare the midrange that it seems you're insinuating is equivalent to a H/C ls7.

It makes my day that you get so upset about the 5.0 lol . Pretty sure you and your lapdog hio said these cars can't make over 500 rwhp NA. But now you wanna say let me know when one makes over 1000 hp stfu and enjoy the cars no matter the brand
