93 intercooler

[DThelen]

My dad has a 93 2wd with smv5600. Larger injectors and 16 cm turbo housing. K N filter. He has trouble with smoke, even with adjusting the screw and boost valve on pump. He talked to Banks today and they told him the Intercooler is restrive. They wanted to sell him a $1300 intercooler.

Is this true, Were would a person get a higher flow intercooler for that truck cheeper.



Thanks

whatever they can do to make a buck. or lots of them. how could they posibly diagnose that over the phone? if you want it checked, most good local radiator shops can check them, find one that works on big trucks.



as to the smoke problem, i can't be of much help. look at some of the obvous stuff, i cleared mine up with a BHAF and a 4" exaust.

Call PDR, (Piers Diesel Research) 1-604-888-4159, ask for Mark. They have them made, and get them in a few at a time. I paid about $700 for mine back in the spring. The cores are HUGE compared to the old one. Banks is over priced and over rated IMO.

Did you test it for leaks? If it's ok make a temporary tube out of exhaust pipe to check flow, just watch the EGTs. I ran my truck on a temp tube for a month til my IC came in.

I'd start by getting the intercooler and the entire intake system pressure tested. Also, what kind of larger injectors are they? Some aftermarket injectors (besides the obvious PODs) have a spray pattern that isnt ideal for our compression ratio and piston bowl design. That will cause smoke as well, even if they look great on a test stand.



Also, if the pump isnt up to par, you will get smoke, no mater how much air you force through the engine.



What kind of EGT and boost readings are you getting at various throttle settings? That will help as well.



Also, if the truck still has the stock H1C turbo, you are out of your efficiency range in the mid to upper 20s boost- drive pressure exceeds additional airflow, and you creat heat in trying to drive the turbo.



What kind/color is the smoke? Is it a rolling black cloud, or is it more a greyish haze? Injector washer thickness can affect the performance and smoking. I. E. guys ahve cured the POD bluish/grey smoking with thinner washers; I stopped the dark smoke in my mom's 92 with thicker ones.



That might help, or it may cause more questions to arise. In which case, that will make your membership pay for itself.
