That is wheel hop on the torque curve.

Do you happen to know which fuel they used for these tests? Regular gasoline at which octane, or did it happen to be E-85?
thanks for your response

with that big a jump in such a short rpm window Ford must have bought V-Tec from Honda! LOL!

This is so old news and dyno be dammed just drive them they both have advantages and dissadvantages I think the big advantage is when the ECO blows buy while your sitting at the E85 pump Calculating if the reduced MPG is worth the few pennys saved

If the eco doesnt go into safe mode :/

I ran e85 in my 5.0 and my butt dyno says the truck was faster.
I also ran in our local drag races, 1/8th mile with tree lights and time slip. My ET's with 87 fuel best was 10.01. My ET with e85 fuel on a hotter humid day best was 9.96. Got a lot more wheel spin on e85... that could have just been track conditions though. E85 had top speed on 1/8 was 72mph, 87 fuel top speed 71mph.

What wins races is the area under the hp/torque curve on a dyno.

The 5 point slow will lose...end of story.

People are arguing about what 5700 lb truck is faster, seriously. I can see a discussion about towing, but speed? I'll put this to bed, who wants to line up against my SHO?

I do on my Z1000
