i thought that rating is for the entire car..not the engine as it is only a small percentage of weight. considering hp/lb is more for entire platform not just a engine.

when talking about efficiency of engines hp/liter is more useful than hp/lb

**mbrownin** · 02-21-2010, 05:26 PM

I was talking HP per lb. engine weight, not vehicle weight.

Granted it's all hypothetical, but assuming identical power curves, and comparable total physical size, which would you rather have - an 8-liter engine that weighs 300 lbs, or a 4-liter engine that weighs 600 lbs.

My point is, the Ford uses much more complex, and consequently heavier, methods of getting the HP from the engine. (e.g. DOHC, valvetrain).

The 5.0 Coyote engine weighs 430 pounds. The LS1 weighs 390.

that means nothing in the long run tho.

Wow ive heard alot of bs,but never that one before.

**98Z28CamaroJG** · 02-22-2010, 08:51 AM

yeahhh i'm not feelin this lighter motor thing

**02sunsetorangeZ** · 02-22-2010, 12:22 PM

yea a stock terminator is very respectable

ok yea and that's why i said its "technically" not but anyways yea its sad when a ford has to supercharge their car to get 390hp out it vs. a camaro which is naturally aspirated and comes with 350hp

i used to think this way, made a whole thread about it. then got laughed at and had to change my name. it used to be zboner

If the cars are otherwise the same, making the same power, then you're right.

**Hi-Po** · 02-22-2010, 05:29 PM

HP/L is about useless when comparing two different engines with different cubic inchs. Its ricer math, and is a pointless argument. The redline on the the new 5.0 is 7000 RPM, compared to the 6200 of the LS1. Again, HP/L is ricer math and only gets brought up to make them have something to argue.

I always wondered where zboner went LOL.

Who cares about redline? You could put new pushrods and springs in a stock ls1 and raise the rev limiter to 7000rpms. Doesn't mean you will make any power from 6300-7000 but you would still have a 7,000rpms redline, which means nothing.

Same final drive ratio, same numerical gearing in all gears of a transmission, same weight of the trans, same weight of the doors, fenders, hood, quarter panels, all the glass, etc. etc. etc.....

The only point in time any car would be the same is if you're comparing the same make/model/year vehicle to another, and even then, what if one has 1/4 tank of gas and the other is full. One may have tools or something of the sort as well in the backseat... you really should stop while your ahead

I took it as an example of sarcasm

I thought it is all about unsprung weight.. N/M your talking about motors...

Lighter crank,pistons,rods,flywheel,clutch or trq verter, etc...

The real ratio people should be looking at is power to weight. That's the only one that should matter.

He probably meant the 5.0 makes peak power at 7000 rpm vs the 6200 of LS's, which they do. HP to weight, the 5.0 should have a slight lead, however the final weight of the mustang is not out yet that I know of so an accurate hp/weight comparison of the SS vs 5.0 is still up in the air.
