Give 'em some time...

i know....the battery tech is coming up fast.....but i don't think it's gonna make it to that point in my lifetime. if it does, i would think then that scifi is happening too, and i'll be able to go down to the corner store and pick out a new body for myself.

we;ll have to have cleaner/more efficient sources of electricity too.

because that would be a fair comparison.

Isn't the engine in the GT500 a hand build "low volume" produced engine? I would be interested to see if Ford corrects to SAE J1995 or SAE J1349. I know GM certifies to J1349 which is "net" engine power. I would bet that Ford corrects to J1995 which is "gross" engine power. That would account for a few percent of the difference between the two. I keep hearing people say "GM under-rates their engines" and I think it's just they rate them as net and not gross. I am very interested to see how this Mustang performs. Love them or hate them, you got to hand it to Ford. It took some stones to go for broke like this. Hope that thing stays together...

they're built at the romeo niche plant. they are hand built...and the builder even signs it i understand.

i don't know which standard they rate this engine to though. when you say gm rates "net" , is that net at the flywheel, or at the tires?

That Romeo plant is 6 miles due North of where I live.

GM rates at "Net" power and that is still flywheel power on an engine dyno. To keep it simple let's just say that the power is measured using all of the "ancillary" systems it would have on it when installed in the vehcile. This would include air intake syetm (air filter box and piping), FEAD and the exhaust system, including the resultant restrictions. Many manufacturers rate "Gross" power which usually does not include any of those systems/restruictions. Net power is always less than Gross power for a given engine, and it could be as much as 5% less. This is a general description and I'm not sure what the acutal gross numbers for the LSA in the ZL1 but I know GM rates at Net and certifies this with an outside party. GM ratings show the power available with the driver's butt in the seat.

Not sure what Ford does but I would bet it is Gross power.

Nobody does "gross" HP anymore. Most (if not all) converted some 40 years ago.

The 2013's 5.8 is SAE certified at 662 net HP.

i know the difference between net and gross. but i've seen some people refer to rear wheel hp as net, and others as you described above.

i don't think ford's rating this engine at gross, as i thinnk that no one uses that anymore.

The GT500 was tested with all the accessories on the engine.


And a net hp does not give you the power available with the driver's butt in the seat. A chassis dyno rating would be needed for that.

The new motor is to J1349 and so was the 5.4.

Also as of 2005 if a manufacturer claims to be SAE certified is has to use a third party.

Net HP gives you everything but driveline losses.

SAE what? SAE alone doesn't tell much.

OK, I hadn't seen that referenced anywhere.

your butt in the seat gives you everything + driveline loss.

It really doesn't make a **** what the power is at the flywheel. The power to the ground is what is really important.

Ok then. Nevermind, and have a great day!
