Where does Roush claim this? Per truck trend the nightmare is a 14sec truck. And mine weighs about 550 more lbs. http://www.trucktrend.com/roadtests/...s_pricing.html

second paragraph and also in the owners manual

 

I see. To bad they don't post some hard numbers. I'm sure mine could run faster with better traction. Either way, I'm happy with it. I did it all myself except for the tune which sucks and will be redone ASAP and it didn't cost me $40k. Heres a calculator which seems to be very close to what I'm running and what Roush claims. http://robrobinette.com/et.htm

 

You guys would SMOKE me according to that calculator. lol...which is true I know. Love the way mine runs though.

I might be interested in adding something like that to mine one day. How much time did it take to take off factory and put new ones on?

 

BTW...I resemble that remark...lol total cost of my truck with mods is well over that number.

 

lol 13.79, but i have a tune and 2.6" pulley soon ill be doing headers, electric fans, and ill get some drag radials, and eventually ill port the blower and weld the sound slits shut to make this baby really whine your truck vs my truck would be a good race thats for sure

 

as mine is right now, it cost me $32k with only 2,000 miles on it so im pretty happy with $$$/power ratios with this truck hahaha
