Testing the waters on a 10-12 upgrade from my 2008..

As it says thinking about trading the 08 for newer year. Just to start with, I installed the standard SCT4 program (91 octane), pulley and Cold Air Intake to boost the hp, theoretically, from 500 to 600 +/-.

 

Are these simple mods the same on these years? In other words, could I do a relatively simple "bolts on" to increase the hp from 550 to 650?

 

Don't want to buy a newer model and have less HP.....

Actually, you would break even. The mods you did to your 08, are the mods the 2010-12's came with from the factory to make 540hp, 40 more than the 2007-08 came with from the factory.

 

Putting a intake, pulley and tune on a 2008, and a 2010, will net you the same HP, about 540rwhp. The only small advantage the 10's+ have over the first generation, are the knock sensors, when both are modded the same.

Yes. The same mods are available for the 2010+.

 

Here's another way of looking at it. The 2010s came with a factory cold air intake, earlier models did not. So putting a "cold air intake" on a 2010 isn't going to get you any more power. VMP tested just JLT intake on a 2010, and it gave them 3hp. Putting a cold air intake on a 2008, will gain you more, because it never had one. The pulley is available for all years, as is the tune.

 

A 2010 will dyno about 470rwhp, a 2008 will dyno about 450rwhp. Both vehicles being stock. If you put a pulley, tune and intake, on the same cars, you will end up making the same power, around 540rwhp. So that's what I meant by "break even". Yes, you increased the HP MORE on the 2008, but that is because it was lacking the cold air intake, and less aggressive stock base timing maps because it didn't have knock sensors back in 2008, so the Ford engineers had to be conservative with the timing. A 91 or 93 tune will take care of that, and that's why, all said and done, you end up at the same 540rwhp regardless of the year Shelby you buy.

 

The pulley, tune, and intake on the 2008 will net you around 80rwhp, and only 70rwhp on a 20010. Only more HP on the 2008 because it started with less from the factory, but the mods and tune even out the playing field.

I currently own a 2010 with pulley and tune. If I was you I would personally find a way to purchase a 2013/2014 GT500 if you want a real bump in power. Like Alibi said, your wallet will limit how much power these cars produce

 

I think I would agree. By the time you take a 2012 or earlier car and bump it to the 2013/2014 specs you will have spent more on mods than a 2013/2014 car. The 2013+ cars are about as "done" as you can get from the factory.

If you do a blower swap (Trinity or VMP gen2) injectors, BAP (if needed) & updated tune on your 08 you will be around 650 rwhp+-

Pretty much a bolt on job that takes 2 hours start to finish, same results 07-12 cars for a lot less $$$ than a 13/14 car

A 2013-14 isn't in the cards for me.

If 2013/2014 isn't in the cards I can personally say the 2010 is great. Yes the 2011/2012 has an additional 10hp, 100lbs lighter, electric power steering, and glass roof option but....I've put over 70,000 miles on my 2010 and it still runs perfect
