The 2011+ Mustang Thread

So the Ford 5-oh comes standard w/ headers? And the Cheby SS LS3/L99 does not? OK, I see where Ford makes some gains there. If the LS3 had headers, (apples to apples) it woud make more hp, right? I agree the math should be basicaly apples to apples on major engine components; if one came stock with a turbo, you would want to know what the other engine would do with a turbo also.

Ford didn't leave too much on the table as far as squeesing more power out of the 5.0. You can always go forced induction on any engine and get more, but with the 6.2, you can get a $hit load more with a cam and some bolts-ons.

When I was having my short flirtation with the 5.0 Mustang, the sales manager said, "I can get you 500hp for not much money and Ford's warranty will still cover you. As the lack of a tip auto ended the romance, we never got any further.

I gotta say that's pretty cool of Ford to actually offer warranty-able power upgrade options. I'd love to see GM do this, but I'm guessing Ford does not warranty up to 100K miles?

Apples to Apples?

I mean does anyone really believe a 5.0 vs a 6.2 is apples to apples?

We can only go off what the cars come from the factory with.

Where the 5.0 will shine, at least once you get some good rods and pistons in it will be when you force feed some air into her. These DOHC motors love boost. And with the heads flowing better than GT500 heads, I can see a forged 5.0 making more power or the same power as the same amount of boost on the GT500s 5.4.

Any reason why the LS3 won't respond just as well or better to FI??? (I know the answer BTW, go look up the FI numbers the Vettes are getting)

I never said the LS3 would not respond well to boost. It should respond well, very well.

The 5.0 might, and the keyword might, respond better do to the heads. It is just the nature of the beast with OHC motors. They love boost.

Interesting. I'm new to the OHC and boost concept. I have some homework to do...

honestly i dont really see the the LS3 gettin any better numbers than the 5.4 DOHC when supercharged. Call it black magic or OverHeadCams but the current Ford engines are making excellent power with the superchargers even against larger engines with superchargers. Even the big dollar ZR1 engine with a supercharger upgrade in the Hennesey camaro and hennessey ZR1 makes 700hp at the crank. The GT500 engine with a kenne bell upgrade makes that much too, BUT AT THE WHEELS!

i dont know if thats really the case, i know thats what a lot of people WANT to believe, especially on a GM board but the saleen makes 440hp (almost 30hp gain) with a catback,pullies and tune. I think with an aggressive tune (something thats not 50state compliant) will net a bit more power still.But the saleen is already said to trap 116MPH!! Is there more to be had with an LS3? quite possibly but the 5.0 is by no means maxed out from the factory as the rumor on message boards have people to believe.

I had the LG Motorsports LS3 twin turbo package in mind: http://www.lgmotorsports.com/catalog...oducts_id=1973

1000+ RWHP

Turbocharged 5.4v. First video is dyno run. Second video is breaking the standing mile record.






But once you get to that level it is mostly about who has the most money.

theres already been people making that kinda power (and more ie 1400rwhp)with the stock 5.4 longblock with turbochargers. That doesnt even require lifting the valve covers!! Thats stock cams,block,crank,rods,stock pistons, everything but the intake manifold and exhaust. Hardly anything on the LS3 you showed is stock. Anyways i prefer to talk about something more realistic than these big dollar engines and stick to something a lil more simple like supercharger upgrades and things like that.

Exactly. My point is both engines are limited only by money. My guess is that the cost for a 200HP bump to the 5.0 will be the same for the LS3 (about $7000 for an SC and tune).

Although, I'm still doing my homework, I expect to find that FI on Ford engines is no different than GM engines. You just see a lot more cammed GM engines because the higher displacement yields more "untapped NA HP".

If the OHC is better for FI, are there any theories why?
