Update: More confused on power

[cougar]

Looking for more power without more smoke, or at least a minimal increase.
I have already turned up the pump, but that made a lot of smoke. I changed the turbo housing to a 16 from the stock 21. That cleared up the smoke but now what????
Injectors
Fuel pin
Governor spring
4" exhaust
These are items I'm considering, but what individual or combination will give me what I'm looking for? AND, I want to keep the smoke down, had enough of that with the Ferd. That thing could choke a city. I want to keep the EGTs down because I tow. And I want to keep decent fuel mileage while cruising.
Perusing other threads and forums these items were covered individually with only gobs of smoke and power in mind. So I'm a bit off the beaten path here.
Any ideas or suggestions?

For an injector a bosch 190 should be a good mild upgrade that shouldn't create much more smoke and should help a little in the mileage area. On the turbo your gonna need something that will spool quick and supply a good volume of air, but not choke off the exhaust. I believe the stock turbo off of a 3rd gen is supposed to spool good and push a good volume of air. I can't remember what the turbo is, somebody will jump in here with that info. The governor spring is almost a must have for one of these trucks, it makes that much of a difference. After you do a governor spring you should look into upgrading you lift pump to keep your fuel pressure up, which will help with mileage and power. One thing you can do to help keep smoke down is to back your smoke screw out as far as possible and turn your star wheel up. You won't loose any power doing this, it will just take more boost to get the fuel pin moving. With a good turbo and a mild injector upgrade I would think your egt's would be low enough that you wouldn't have to worry about towing, and you could add a bigger intercooler to help in that area. 4" Exhaust and an intake with a good filter are always a good idea.

Thanks "gear jammer 91".

I was looking at the 190s over the PODs and others.

You didn't mention a fuel pin. Is this more useful for the big injectors? I did read in one article that you can turn it 180° and get a little more out of it.

My turbo is stock except for the smaller housing.That eliminated probably 90% of my turbo lag. Set up as is I can hit 24 pounds boost. My EGTs get really high when towing up a long hill though.

4" exhaust has been on my list for a while and a BHAF as well. The filter needs to be protected though because of the condition I drive in.

I am having trouble finding 1st gen parts. Is there a list of 1st gen parts sources?

Rotating your fuel pin will give you some free power. A custom fuel pin will help on power more, there are a couple choices there is a dennyt pin, he is a member over on diesel truck resource. He makes and sell's fuel pins himself so all you have to do send him a message on that forum. There is another user who makes pins he goes by alwaysworking, I can't remember if he is a member on here or over on dtr. You can also search ebay for fuel pins, the original pin is an old smokey fuel pin, stay away fron the bully dog pins people have had a lot of issue's with them. First gen parts are a little harder to find, any turbo for almost any cummins from a first gen to a common rail will bolt up to our engines, so there is a lot of choices there. Injectors need to be 1st gen specific or they won't work properly, and pods are supposed to smoke pretty bad. There are only a couple options for exhaust one is https://www.sourceautomotive.biz/index.php the other is http://www.stans-headers.com/. These are both supposed to be a good product with no issues. Upgrading your turbo will really help get your egt's under control, a better turbo will spool faster and supply your engine with a bigger volume of air to burn the fuel your giving it.

Turbos are rather spendy, so It's not at the top of my list for replacement.
What would be an appropriate turbo if I do;
190 injectors
governor spring
and 4" exhaust

Any difference if a fuel pin was added?

[PToombs]

Your stock turbo will work just fine with that stuff. The 190's actually have smaller holes, so you will be burning less fuel and getting more out of it. A 4" exhaust and a BHAF are the best mods you can do to keep the EGT's down.
A governor spring is a big bang for the bucks. It will give you more fuel across the whole band.
If you pull you fuel cone and look at it, just turn it so the deepest side is towards the front of the truck. You can't go by 180*, they are all different. Some are off 180, some are set to the deep side from the factory. I think the installer just stuck them in which ever way depending on his mood that day.

Thanks guys
But I do have more questions

#1 Any part # for BHAFs?

#2 What is the flow rate for a stock lift pump? The pressure is 5-8psi. The only flow info I have is .7qts in 30 seconds at idle (or 21gph) min. What is it at 2800rpm?

[PToombs]

If you search you can find the BHAF numbers, NAPA and Fleetguard should be listed some place here.
I've never seen flow rates. 5-7 psi at idle, not less than 3 psi at WOT.

the wix number for the bhaf is 42790. btw, wix makes napa gold.

[SChandler]

The Napa number is 2790. It was about $65 in store last time I bought one about a year ago. Try this site to buy them at a cheaper price: http://www.fleetfilter.com/. The Wix/Napa filter is about $20 cheaper from them. I bought one off of there one time, shipping was reasonable and quick. A 4" exhaust and a BHAF netted me EGT drops in the 100* range. Well worth the effort and time.

You should be able to get a good afe foam element air filter for around $60. That's what I'm gonna do when my BHAF needs replaced since the foam element ones are reusable. https://www.sourceautomotive.biz/index.php Sell's the air filters I'm referring too.

[beerboy81]

for 5.9 cummins - #46343 (89-92) 450 cfm and #46338 (92-93) 290 cfm

BHAF out of a bluebird skool bus with 5.9 cummins - #46500 330 cfm

Donaldson #46423 620 cfm and #42790 680 cfm both go for $43 with a 4"
inlet - great if you have ASA intake tube!

If you get one of the paper filters, be sure to also get the Outerwears waterproof prefilter. It will keep the big chunks and some of the road spray off of the filter and make the filter last a lot longer. I have something like 50k on the paper filter in my 90 and it looks good still. You can get the Outerwears cover direct from Outerwears http://www.outerwears.com/ or from these guys: http://www.vulcanperformance.com/Outerwears-Prefilter-for-the-Big-Honkin-Air-Filte-p/1085.htm. I think I bought both of mine from Outerwears. If you call them about the BHAF prefilter, they will know what you are talking about. The Outerwears part no. is 20-1085 for the one that fits the Wix 42790.

[beerboy81]

can anyone compare the BHAF to the AFE filter that comes with the ASA Mods.. like the cfm rating, noise, and longevity..

the AFE is a lot smaller of a filter than the BHAF.. so that got me wonderin in comparison

[gear jammer 91"]

I want to go with the afe because it is reusable and, in my mind it should filter and flow better than a paper element filter, but I have nothing to back that up with. I have also been told that you can hear the turbo better through an afe or similar style filter (that's the main reason).
