The truck i beat was an 09, 2wd crewcab. Cold air, long tubes, borla exhaust with no cats and 3.92s, custom tuned. Went back to the track last wk and he was there. He told me he went a test drove a new 5.0 with 3.55s and it didnt feel as fast as his truck. He asked if i was spraying mine, which im not. I let him look under the hood. He said it must be the tune, and it is. These motors really wake up with a tune

As long as the hemi doesn't have a stroker kit ported heads, intake, a cai, long tubes and a cam you will be fine. To the guy that beat me that was stock. Other than that there are no other hemis that have been even close to me, no matter what year mods or cab configuration.

The 5.0 L is way underrated by Ford. I think to sell more ecos. There I'd a dyno test out the from pickuptrucks.com that showed 311@ 5450 rpms, vs the eco 316@ 4250. The coyote was a 4x4, the echo was a 2wd. Which means the coyote was making alot more house power at the rear wheels. The 4x4 drive systems lose around 20% between the flywheel and the rear wheels. That equates to real horsepower of 388.

I test drove both the Ford, which I bought, and the Dodge on the same day, with the same specs, and the coyote felt alot stronger than the hemi, especially when passing at highway speeds.

Sorry but the 4wd doesn't lose 20% to the rear wheels...

I've been doing some research and for the older f150's 97-03 I've seen 30% drivetrain losses from an automatic 4x4 setup. Not so sure about the newer ones.

You sir are wrong. Do a quick google search and you will quickly find out. Rwd vehicles lose around 15%. 4wd vehicles will lose anywhere from 20%, to as much as 25%. This is proven physics. Go troll somewhere else.

So what was meant to be said was that the 4x4 system leaches about 5% more than the standard slush box loses on its own.

it's common to see 4x4s lose upwards of ~30%. 2wd somewhere around 25%... 2wd 5.0s tend to put down about 270rwhp... the 311 figure if I recall was a very early '11 model and maybe even a ringer from Ford...
