I have 99 3500 with banks ottomind,exhaust brake 4" exhaust. my exhaust temp will get 1200 degrees just going through the gears. if I'm loaded a small hill will kill me on the exhaust temp. how can I cool it down?

 

Fill out you signature under User CP so we know what you drive and what is done to it

 

Any guages? What boost levels are you running?

 

something has to be wrong banks would cut power once it gets that high and i dont think it can even fuel that hard to have 1200 going through the gears. do u have an intake on the truck

 

25 to28 boost, the ottomind is 9 years old they didn't have a cut off point I have a stock intake would a oversize intake help if so whats the best?

 

Either the ottomind's pyro isn't reading correctly or you have a boost leak.

 

Have you checked to see if your e-brake is stuck shut partially? That would cause a good restriction in the exhaust.

 

I have the same problem with mine. I was thinking it was my injectors that were causing the heat, but maybe not. I never thought about checking my exhaust brake to see if it is not opening all the way.

 

Do a search for BHAF, its cheap and might help. Most of the aftermarket filters can be bought by themselves as replacement filters if you wanted to make your own heat shield. You don't really need a bigger filter, but it might help with the temps.

 

i would agree with ph4tty he has always given good advice. pm sent.

 

It was worse before I put the brake on the truck .

 

Where you at in VA?

If your exhaust brake checks out and you're positive you don't have any boost leaks, you might want to look at the EGT gauge itself. Not sure what gauge you run, but I had problems with my Isspro one time which read high.

 

I need to find something out with my pickup to. If i turn both of my chips up i can get it to peak out at 1650 for a second then i just back off. Im pushing about 45-50lbs of boost. Need to figure something out because i have a dyno day coming up soon and dont want to melt anything down.
