I am curious and want to compare. What is your EGT and boost level at 60 mph in OD not towing and not going uphill?

mine today is at 15psi and about 900 degrees.

 

Cruising at 60? how does one get that slow, gearing?

Speed limit here is 65, most traffic is between 70 and 75.

Most of my cruising is at 70,
boost right around 10-12,
and EGT right around 800-900 deg.
RPM's around 1700.

I've found if I try to stay with most of the traffic, my fuel mileage plummets, so I keep it at 70ish.

Ok, you probably wanted more of the undervalved crowd to answer.

I bet you have a 4.10 rear end.

Cruising @ 70
-6-8 pounds of boost
-EGTs about 650-700
going up any hill the EGTs will move up to about 800-900, with about 15-18 pounds of boost.

 

60mph about 750 temp, don't have boost gauge.

 

Ummm, I think around 900* pre turbo. Not sure. I can't remember the last time I drove that slow. I know at 105mph I'm sitting at about 1100*.

 

I'm at 650-700, but that is with little 245's. When I had the 33s on it was aabout 750. Still don't have a boost gauge...

 

At 70mph EGT is 600-625. PSI around 8-10.
Note: 5spd

 

700* at 60 mph...800* at 70 mph.

Boost...level ground....I get 3-4 psi.

Lance - Your boost/temps sounds high, even for stock turbo...maybe it's the lift?

yea I was thinking the same thing. although with the 40s and the 410s, my speedometer is only behind about 2.5 mph at 60. I guess its the increased wind resistance.

 

600 @ 65, 5 pounds boost, this is with a 14cm wastegated housing on the 35. at 120 it is 42#s and 1500 plus and the truck is still pulling hard.

 

@65mph 5-6psi 550-600 degrees

 

Don't forget the rolling resistance too.

 

@ 60mph, 4-5 psi and 750-800*.

 

Probably around 4-5lbs of boost and 700 degrees

 

@60, 400 POST turbo & 2-3 psi...
