I have my pump maxed out and sometimes my EGTS get pretty high and I was wondering if anyone knows how to get them to stay down a little bit without turning my pump down or is that the only way?

 

Dropping a gear and bringing your rpm's up is a good and cheap place to start. Yours is a '92 right, so you have an IC already. Water injection is a great way to bring it down. A bigger compressor on your turbo will help somewhat, with the added bonus of more power!!!

 

What about a different air intake system or bigger injectors?

 

Bigger injectors = more fuel. More fuel = more heat. Not exactly what you're looking for I wouldn't think. Different air intake... at the filter end or the manifold end? To be honest, I don't think either is going to help drop egt's that much. More air is good to get the engine breathing better, but unless you're really choking the heck out of it, it's not really going to help. An exhaust system on the other hand will help immensely. Sorry, I forgot that part. I've read drops of between 50° and 200° from a 4" DP alone, so that may well be a good way to go...
....Unless you already have one. I can't read your sig from here.

 

how high are your EGT's getting too? you have stock injectors?

 

I was grossing about 22000 pounds and some times I would hit 1400 degrees on hills but I didnt hold it there for a long time maybe Im just expecting to much and yes I have stock injectors.

 

Like kd93 said need just a little more air/exhaust upgrades. Before turbo and exhaust, head ported and manifold ported. With no load WOT I couldn't get over 1300 EGTs. and after upgrades it won't get up over 1000-1050 no load WOT. I'm runnings stock injectors right now with pump maxed out and the other day I groosed 30920lbs. and the EGT's were 1250 to 1300 WOT. my temps are pre turbo.

 

I changed to 4in turbo back exhaust and it helped alot hardly ever had to fill my water injection anymore.

 

Those are some good numbers! I'd be very happy with those.

 

Anyone know of good places to order 4in exhaust?
