Engine/Transmission (1994 - 1998) DD III's VALVES+ GSK HOOOLY COW

[1sand0s]

Finally, after all this time, I got the day that was warm enough to make the swap.



Talk about a difference!

These things made the motor run like a watch, but she makes funny noise around 2400 and up (Always did though. )



now that I see how little soot farting I get when driving it normally, I am glad I spent the extra on these and did not go for the 370's



Smooth as silk.



Thanks John!



Did any of you get a rich smell to the ex after doing it?

Also, is it normal to drive with traffic only using 1/8" of throttle travel? I mean I go over a bumo and just about run into the guy in front of me. VERY touchy.



Besides the trans sounding like it is going to come apart, when flatfooting the thing up to 2800 in 5th gear, the highest I see on the meter is 1200 and by then, the beast is going so fast, it is not a safe situation.



This surprises me because everyone seemed to say that the number 6 plate would not deal with III's, del valves, GSK. I was warned that it would run too hot... by a lot of people.



Unless my guage is wrong and I am about to melt dow a piston, the thing is FINE just like it is.



I dunno. Stock ex. cat/muff not even cut out.



Why all the talk about the #6? So far, I have not seen issues.

Sure did make a HUGE difference in the truck though.

Unless it is from all the power , maybe the GSK needs tweaked a little so it isn't so touchy.



Sounds like you are having fun.

I remember 1200 degrees ... it's been a long time. The best thing about 1200 max is there are plates with lower #'s. Oo.

Sounds interesting. I like my #6 too... ..... What other mods you have besides DD IIIs and the GSK?

Is that to suggest that MORE ex temps would be okay?

with my setups (See sig), I am seeing EGT's through the ROOF! I dont know what the deal is, maybe not enough air flow? something is going on, and I need to solve the problem PDQ! Any suggestions?

Some obvious questions:



Have the high EGTs just started recently?



What timing are you running - has it slipped?



Air filter clean?



What boost levels are you seeing - same or reduced?

Does anyone test their pyro, thermocouple etc. with a pyrometer tester to assure that gauge temp = actual temp ?



I bought one sometime ago and always ck. for accuracy prior to installing the pyro set up on a truck. Often the thermocouple causes the reading to be out of spec. ? Several hot and cold concerns have since been alieved(sp). .



Good luck

I sure would like to test mine!
