Regis Riley and super snake

@@e.honchoo9596 a super snake is just a factory souped up gt500. Its not really coming from the ford factory that way the shelby company builds them after production of it. This is a normal gt500 straight from the ford factory with 662 hp. The tvs is mainly what does it...slap it on an earlier gt500 you got close to the same power for way less money.

That's at the curve....

***** Those gains are throughout the curve, not just peak gains which were right around 50. If you look at your dyno results, you'll see that your stock and after numbers were probably similar, but look at the change in horsepower and torque between 3500-4500 RPM. I'll bet you're in the triple digits, as well. -Chris

AmericanMuscle.com It would and interesting race between this and project blackout...

+KWorker lol are you serious? The video clearly shows 45 whp, not 100! It does show a huge increase of 100 whp at around 5200 rpms. The way American Muscle corrected that power curve is just impressive. The Shelby was clearly restricted from factory probably because of noise and emissions but once the engines are open up, the 13 Shelby is a monster.

Bubba Blue no the real ones are the 13 and 14 if you get a 12 you’re wasting money

concur, 13/14 is where its at

@@BlahBlah-ps2uc yea the 13 up also cost alot more usually than a 11-12 does...sure they're better but so is the bigger price tag. 11-12 gt500s are really good cars and still tons of potential so if you could get one for 10g or so less than a 13 I'd go for it all day. I know a guy who got a 2010 gt500 with 70k real clean for 24 g

We always make sure the cars are warmed up before making dyno pulls. The issue is deeper lying in the Trinity GT500's and that's why it usually takes a tune to keep that TB open for the entire power band. -Justin

@@americanmuscle I don't doubt that you guys do warm up the cars, but from what it sounds they are very picky. That's what VMP found anyway. Car closes the TB for a reason. You surely would not think they would leave a big dip in the tune considering they spent hours and hours developing it. Luckily software fixes it though! No reason not to tune considering the gains! Love all the GT500 build videos. Especially after putting the Eaton M122 on my 4.6 GT

moparmaniac21 Even stock, the GT500 could still walk the Hellcat. GT500 is like 600 700 pounds lighter.

moparmaniac21 stop it destroys hellcats

sike, the 13 14 gt500s were the worst at the quarter mile with those gearings.maybe and 11 -12 could beat it. the hellcats could still beat the gt500s stock for stock. stick for stick while spinning to the finish line. it came after the gt500, they already had a benchmark to beat, you think any manufacture would make a car that competes with another to be slower with more time? NEIN!

@@ThaMagnaCarta i guess you didn't compare stats, voted for Trump i'll wager

@@richardthomas1531 hey soy boi, dont bring politics into the comment section. go do that on a CNN page Also im not responding to the OP. besides its no longer stock compared to the STOCK hellcats. which is no longer a fair race.

Ruby Red Metallic

Go to their youtube channel. You will find the 2011 3.7 build. There is no difference in them other then the years, and exterior. Ran I believe low to mid 11s

Thanks you

Of course these guys know what they are doing. So do the engineers at "Shelby" (Don't you mean Ford)? The difference is simple, as the factory is constrained by the EPA. The aftermarket is not.

+Danny Nguyen First, the bean counters at Ford have to worry about a little thing called "powertrain warranty".....so of course the engine is de-tuned to help it last until warranty is over....,.
