Any of you guys put in a after market water temp or trans temp gauge?

Found some Digital Water and Trans Temp Gauge, from Glowshiftdirect.com

Wondering how hard it is....

 

On my 93 i have 2 water temp sensors, one for the pcm and the other for the gauge in the dash. If i were you i would use the sensor if you have 2 for the one in the dash to get your readings. As far as trans i am not to sure on that, might be a way to use the trans cooler to stick a sensor in it. I have a manual tranny and almost no way to my knowledge to but one on mine.

I saw that you have a 3.9. Same as me. I wouldn't pull that big of a trailer. I know my truck wount do it with a load on it. Also you will loose power if you straight pipe it. Put if you do use smaller pipes other wise you will loose back psi. Leads to frying your valves after a while.


"other readers, correct me if i am worng"

 

It really depends on the size of the pipe. High velocity of the exhaust gasses is very important, and running a large straight pipe will significantly lower the velocity, and in turn, increase the back pressure. For the best performance, you want no backpressure... backpressure in the exhaust causes the engine to do more work pushing out the exhaust gas (work it could be doing to move the vehicle), but you are correct in saying that no backpressure can fry the exhaust valves, so lowering, but not eliminating the backpressure is the best idea unless you want to buy titanium valves, which won't burn up. But the biggest thing most people don't understand is you can easily go too big on the pipe diameter... there is a reason the engineers decided to use the size pipe that is on the truck.

 

pretty sure its like 2.5" and the tip is like 3.25"......i still have the cat!
