I am trying to lessen the amount of smoke.I have a 98 with 3GSK,#10 plate,BHAF,4 inch MBRP exhaust.I understand that they are smoky by nature of the mechanical pump,but I have sid the AFC housing back from full forward to about half way and adjusted the starwheel,but I seem to really lose low end.I dont mind smoke when I am really getting into it,but dont want to be wasting fuel.Is this just the nature of the beast or do I ned more turbo?Love the truck just dont want to kill things with the tail pipe.

 

I think a little smoke is always going to be present with a modded P pump, just trying easing it up to speed. You can always try sliding the plate back or even get a less aggressive fueling plate such as an #11 or #12.

 

I have a #10 in my 96 with a AFE intake that I made 5" MBRP and with it in the stock position and the star wheel adjusted were it just contacts the spring it will just put out a good hase if I start in second. If I stomp it taking off in second or with a trailer it makes a decent cloud but it is controlable. If I want smoke I can make it and if not its not to bad I have not had any loss of bottom end. I had it were it looked like a old locamotive with a huge black cloud but I use it bor work and towing all the time so I turnd the star wheel down and the plate. Plus for the most part its just unburned fuel and it cost to much to waste right now. OWEN B fill in your sig so we know what else you may have that may make a diff in what you should do and it will help in the future. Its under User CP. With the GSK it may make a little diff on the bottom end too. Hope this helps.

 

Mine's fairly smoky with the mods I have if I get on it too much too. I don't know if you have an auto or manual but you could talk to the guys at Piers about an AFC spring kit. How's your gov lever adjustment. If it's too high you may be fueling too much at low RPM. Where's your plate set. If I slide mine forward it smokes like a freakin' freight train.

 

I just barely passed my "snap"

test at the Renton, Washington two years ago so am getting worried about whether I will be able to pass it this year. Truck normally smokes very little but when I stomp on it is sure does. Dale

Maybe I need to get around afew more 12 valves,most trucks around here are 24valves and newer,most of our breed are left stock.

 

Adjust your right foot a little as you step into the pump.

 

Smoke is a direct by-product of power, pull the plate and back off the starwheel. Stock my truck wouldn't smoke to save it's life, now i control it almost 100% with my right foot.

 

Not exactly. In a lot of trucks it is just a by-product of over fueling and not enough air. Powerfull trucks will smoke but just becous it smokes dosent meen it makes power. I know a lot of kids around hear that have trucks that make a lot of smoke but not half the power that I do. I can put a trash bag over there air filter and make it smoke like crasy and fall on its face. But yes you can control it with your right foot most of the time. Pulling a trailer I needed to be able to give it some fuel and get going so I set it were it would make a good hase and I could move on down the road. You can still have lots of fuel on the top and just set it just a little less at low boost and rpm. I have no prob with smoke I just dont think you have to over do it at every red light.

 

Well said...

 

I was overgeneralizing but yes in much more detail you are very correct.

But to make big power you will make smoke.

I could not agree more. Not taking a poke at you I just wanted him to know that you can make good power with the setup that he has and not kill any one with the smoke. I have had mine set up were it would stop trafic in town in my 92 but it gives us diesel guys a bad rep. Realy high HP trucks and tractors will black out the sun but thats a little much for driving on the street. All the little yahoos around hear think if they can make it smoke like that by grinding the plate to look like you ran it over and maxing out the AFC and taking out the muffler they must be making 900HP. Probobly making less than stock on some.

 

True in theory I guess, but in practice not very achievable in high HP 12 valves. In a 12v, smoke is an strong indication of power and nearly unavoidable. Drugs would help, but not practical on the street. I'm starting to wonder if you work for Banks? I'm sensing a Gale attitude.

To answer the initial posters question, yes turbo will help, and as others have said, careful with the skinny petal.

 

The original poster doen't have a high hp 12v though. A good clean air filter, rolling into the throttle, and some AFC/starwheel tuning will do a lot to reduce his smoke. I can drive pretty much smoke free, and I have a more aggressive plate, stock exhaust, and the same air filter (brand new) and a 215 pump (I don't know what he has)

 

Na. I work for myself. I just dont want people giving diesels a bad rap. Thats how we get more emission standards passed is because the people in their toyota prius see the smoke and will get on the phone and gripe. And really smoke is a sad indicator of power. I can make one have lots of smoke and almost no power at all. I have nothing agaist smoke and I know very high HP trucks will smoke a lot but you don't have to have a lot to make good power even on a 12-valve were you have to find a happy medium between high HP and tow-ability. You have a very strong truck, much stronger than mine but did you read the 1st post Too Much Smoke. It starts " I am trying to lessen the smoke." Just making tons of smoke dose not always mean tons of Power. He didnt say he wants 600hp with no smoke. So just take it easy. And why is it when people don't think you have to block out the sun with smoke every where you go they say you are like Gale Banks like its a bad thing. What's wrong with being mature and responsible. Ask the guys in Stephenville, Texas what happend when every little high school and college kid started smoking out every body in town. Ask GasgonoFJ60. If you think it will never make us have to meet emissions then keep on and don't cry when your not able to drive your truck because it is not legal. Public image is what gets laws passed. Ask DaleReed about things like that. His barely passed. I love to see the smoke roll at the pulls, especially when its mine, but I don't want this to become like California. Sorry to get off topic. Ya'll have fun now.
