thats what im thinkingDo want! I'd like to swap the motor/trans in my GT as well. :yes
My 2 Cents
Looking that the numbers yes the 5.0 on paper is great and I am sure it will be another excellent engine from Ford. The things to take in to account arent just the fact that the HP is up so much. The torque on the 2005-2010 Mustangs is higher than the HP at 315HP/325TQ (only 65 ft lbs from the 5.0) for the Bullitt and 2010 GT. The 4.6 is a pretty proven engine and has come a VERY long way since the 96 GT. The new 5.0 has a MUCH higher compression ratio and is a much more tuned 412HP/390TQ. Now having worked with engines for a while and having built a few. The thing that is most obvious is the HP to torque ratio of the new engine. Dont get me wrong these 5.0's are going to scream and be an awesome power plant for the Mustang. The thing that has me concerned is that with this engine the modability (if thats a word) is going to be a little more limited than the 4.6. They achieved the 412 HP by timing this engine very tight with a very high compression ratio all to ensure that they were able to reach the MPG that they wanted to boast for people to be more interested in these performance cars. The engine wasnt just an effort to compete with the Camaro it was an effort to reduce emmissions and meet the fuel effeciency demand of the EPA. I thought long and hard about buying my 2010 over the 2011 and the main reason I went with the 2010 was the track record of the 4.6. The 4.6 has evolved over 15 years and has alot of great history behind it. Not to mention the 4.6 was designed as a almost perfectly square engine. It may get less MPG and be a good bit less horse power but in the end the seat of the pants factor the the daily driver with only 65 ft lbs of torque will be almost un noticeable unless you line these cars up and race them. But lets be honest who buys a V8 Mustang to get Honda level MPG?
My 2 cents here would be if you want to wait for the 5.0 wait till 2012. If not jump on one of these awesome deals on the 2010's before they are gone. With the money you could save you could do a whole lot more modding to your Mustang and personalize it.
Just ask anyone who bought a 1996 GT with the "new" 4.6 if he wishes he had waited a few years for it to be a bit more refined. Dont let all the hype and media get the best of you. If you want to spend your money on something that is 30k plus and will smoke my 4.6 or the 5.0 go grab a used GT500 and smoke them both. The engines will always be changing and the 2011 will be out done in time by the factory modifications to the 5.0. In a couple of years the new platform could be putting out over 450HP from the factory naturally aspirated.
nuke powered, lolI wonder where the Mustang will be in 2020
