Or at least that's the general meaning that I've concluded.

The bros have lot of gear....

I am with ya, man. When I first heard that I thought it was some kind of feminine band to close up the uterus.

Just have to get used to the jargon...I guess

There is no doubt there is a power disadvantage, I just know that even in stock form at 324rwhp I wasn’t anywhere close to 100 hp down from a 5.0 😉 if not mistaken it’s about 50-60hp and the weight difference levels things off slightly with the 5.0 still having a good advantage unless something else comes into play (heavier driver, heavier car, extra passenger, etc)

Don’t get me wrong I would fully expect the 5.0 to win, it’s just not a blow out.

but you look good.... even if the sound of your **** hitting the back of the urinal sounds feminine.

I'm not sure people are getting the math here. Everyone keeps saying things like it's a 50-60HP difference etc. The 2015+ Mustang GT 5.0L is rated at 435HP vs. 345HP MAX for the LS1 F-body cars. The difference is 90HP. Even if you want to say that all LS1's are 350HP, that's still an 85HP difference. I know that's not to the rear wheels but I don't see any reason why the Mustang would lose more power than the F-body to the rear wheels.

ahh Well that explains your confusion... once again I made 324rwhp... at 15% DTL that would be 380HP, 350HP max and I would only be putting down around 295rwhp. The 5.0 at 435 would be seeing about 370rwhp with the same rough calculation (though I understand stock 5.0 dyno numbers to be all over the place so they make well over 470 if you believe the stock ones that put down near 400rwhp.

What's the weight difference? Cars that can't account for their increase in weight offering a power plant that can't significantly outperform 20 year old technology? What else is new?

I'm fairly certain a stock LS1 doesn't make 380HP at the crank. That 15% DTL figure doesn't seem right.

MACHXLR8

Usually 15% DTL for a manual and 20% for an auto is a good number to use. Not exact by any means though

Back when these cars were new, I always used to hear something like a 7-10% loss on the manual cars and 15% or more on the automatics. I'm not sure if I'm remembering it right or not. All I know is that 380HP at the crank on a stock LS1 doesn't sound right at all.

Somebody needs to spend the money and get an engine dyno then chassis dyno done on the same day.

Neither of my cars are stock or I'd consider doing it. My 2016 Mustang GT 5.0L is close to stock though. I've done a few small things but the only thing that affects the dyno numbers is the exahust, which wouldn't have a huge impact on it. My Camaro SS is another matter. Besides not having been tuned, and the engine being in the wrong body, it's got 5.3L truck heads and a cam. I haven't a damn clue what was done to them before I got it.

AWPer

If you could only somehow get that $7,000 from that race, then you could have the money to get the dynos done and break open that motor.

MACHXLR8

Agreed. That 15% is being generous. I think that may be more around 10 to 12% if that. Really no way to know though without comparing the dyno numbers from the engine alone vs the numbers from a chassis dyno.

I would not even trust the manufactures advertised Hp since these are manipulated to sell more cars. To be honest, maybe we should not even be concerned with engine horsepower numbers. It is really about what you can put down to the tire anyway.

It trapped 108.58 stock at 3440lbs... with me it was just shy of 3600lbs. You can crunch the numbers if you would like, if sub 10% was an accurate number then all 5.0 manual mustangs would put down 400rwhp... which also doesn’t add up.

Agree with Mach, I made 324rwhp/341rwtrq... regardless of the crank number.

SLP optioned Fbodies have the edge over any stock br0.

I ran across this. Looks like in 1:1 gear the loss is only 1-2%.

I think alot of them dyno in 4th gear is why they are all over.
