EGTs???????

[Archive]

I towed my heaviest load ever today. A full sized backhole on trailer. I noticed something very interesting. As long as I kept the RPMs under 2200 or so I had no problem with EGTs getting any higher than 1100 deg, but as ssom as the RPms get above that the EGT climb with the RPMs. It didn't matter what gear I was in or how hard I was throttling it just the RPM. Anyone ever noticed this?

I think this shows that my turbo is too small for anything over this RPM. What do you think guys.

I have a very different setup but I noticed my EGT climbs really fast at high RPMs. Below about 2,300? I was OK full throttle, but at 2,500+ I had to be careful and back way off the throttle.

I tow really heavy loads with my truck and I have noticed that below 1750 rpm with greater than 30lbs of boost and above 2400 rpm with greater than 30lbs of boost my EGT will climb. It climbs below 1750 rpms due to lack of air cooling provided by the low rpms and climbs above 2400 rpms due to restrictions of stock 12cm turbo housing.
If I keep the rpms between 1750 and 2400 it does a lot better. It especially likes 2000 rpm as long as the boost doesn't go above about 35 lbs (it can go to 42lbs but is very inefficient due to 12cm turbo housing).
I have pulled 8% grades with GCW of 23,000 lbs at 30 to 35lbs boost @ 2,000 rpm with very acceptable EGT readings.

These are the situtions where the Phycotty Air unit comes to the rescue.

illflem, I believe you are correct. Some time ago I added an exhaust blanket to reduce temperatures near the airbox and drilled a hole where the Psychotty makes a 41/2in. hole and ran an airway to the stock airbox. This made an improvement in the EGTs but I think the Psychotty would improve on that just because of better air flow. Also the clamping feature of the Psychotty filter arrangemanet would certainly be better than the stock airbox for keeping dust from entering around the seal under high boost vacuums.

Same here. I run about 19K GCVW. Anyhting over 2200 or so and the EGT's will go off the scale if you aren't paying attention. So much for the 24V's like to rev theory.
