anyone use a 66/71/14 on a commonrail daily driver? i HAVE ONE LAYING AROUND
I ran a 66/65/14 for years and then a 66/71/13ss. The 66/65/14 was laggy and the 66/71/13 worse. To me these are not great street turbos but I hear folks are running the 71/73/13 on the street. I can't imagine trying to pass some one with one of these. If the 62/65/13ss is not enough twins are the way to go.

It's all a opinion of daily drivability, :ft:
x2 Some guys complain about 62s being laggy, other guys tow with 70+mm S400s, its just what you call streetable. I run a ED66/73/14 on my 6spd CR and love it. I also tow a 40ft GN with three race trucks from time to time, no complaints from me.
I run a 66/74/14 on my DD with 37's and 4:10 gears. like said above its not bad at all just need to get used to the different power band. i have run it with no tuning at all as well and it isnt too bad.
I went from driving a borrowed 6leaker to my truck with a 66/74, so it really doesn't feel that laggy. LOL
But at the same time I have headwork, a cam, and plenty of fuel. I got on top of the charger last night at about 2300 rpm so in 5th and rolled my foot the floor. By the time I let out at 3300-3400 I had my gauge pegged at 1600+. Hell TNTR was only on level 5. I think I need more air!
I get about 1500 or so, with my little 90s and a stock pump so it doesnt take much to outgrow one... granted on a CR thats a 600hp truck, but still.
What kind of boost do you see?
