any got a "smoke switch" on there truck? was reading a thread on here and it seems to work on LLY or LBZ but bot to sure on LB7...

Kinda curious about this too

most people think its a bad idea or stupid so they wont post on this topic but it was worth a shot...from my research it will "work" on LB7 but not to the extent of a LLY or LBZ cuz they have a VVT which the computer controls the pitch of the vains...so all the switch does is makes the computer think its got lots of boost and over fuels...seeing how LB7 is fixed vains and boost is controlled by fuel, it should work but once it starts to over fuel it will make boost eventually faster then the VVT motors

Well if you do it, post me a little tutorial

yea i might do some testing on mjy truck and my friends lb7 thats more stock than mine and see if the results vary at all or if its worth the time and small amount of money...i meann all it is, is a switch and a wire to 5v and ground on map sensor....just had crappy weather here lately so haven't had chance to play with it

ive read that thread and from what i remember you need a lift pump if your going to be using it often. if not it can overload your injection pump and cause some damage.

i would be interested in having one so i can smoke out a rice grinder every once in a while.
im not savy enough to just start tearing into the truck and making a system from scratch..

Yeah keep us posted im interested myself. I'm glad that someone finally started a thread about I was going to a while back but decided not to lol for the same reason stated above.

A smoke switch wouldn't be very effective on an LB7. Even with all of the limiters removed from mine with EFILIVE and full fueling at any RPM when I mashed the pedal, it would still only smoke for a few seconds before the boost comes in and clears it up. This is with a lift pump as well. The LLY, LBZ, and LMM can have a smoke switch since they have a variable turbo and can kill the boost completely and command full fueling easily with just a switch.

i have a lift pump with ppe 425 and can roll lots of smoke around 50 (low end of 5th) but only for like 10 seconds tops...the only way i can think to do it is on board air with a tee plumbed into wastegate line and solenoid to let air into boost line to open wastegate as to not make boost at all and just over fuel it...this however means u need onboard air source and some engineering which wouldn't be that hard...i have most of the pieces including the solenoid from my flame kit(thats where i got the idea)....so all u would do is:hit a switch, air pumps into boost line, opens wastegate and mash pedal no boost+over fueling=smoke....then release switch and solenoid closes, cutting off air, wastegate closes, normal driving again....i may have to try this,lol

caught my intrest.

in cab adjustable BOV would be the elegante way of going about it...

the oakie way of doing it...a big arse plumbing valve plumbing into the pressure side...

i know a adjustable bov would look more professional too, just last time i looked BD Diesel made one that was $1,800 kind of pricey for some smoke...thats why i'm trying to figure out a cheaper option

Someone has to say it so might as well be me. Making smoke is just plain dumb. Not only does it give our diesel trucks a bad name, it's illigel, will get you a ticket, is hard on your truck, and make it more difficult for all of us to get our sport accepted by the general public. If you must make smoke do it on the drag strip or pulling track and not on the street. I turn in every idiot I see intentially smoking someone one out or doing burn outs. What exactly are you trying to prove other than you have a single digit IQ by making a bunch of smoke?

I can agree with you 50% subman but the other 50% of me will not agree with you simply because its fun to do but just not all the time. Most of us on here probably have legiment reasons for smoking people out. Like for instance tailgaters not everybody drives fast not everybody drives slow now when some butthead rides my tail I myself smoke'em because I dont want to have to buy a new bumper when they rear-end me. Now you cant sit there and tell us not to smoke people out when all the videos Ive seen of your truck on youtube are pretty darn smokey. Infact look at your avatar look at all that smoke? I bet sometimes if you ever drive that truck on the street thats if its street legal (not a trailer queen) that you get the urge to blow some smoke and dont lie? You do don't ya? Now for turning other people in thats just wrong a little smoke never hurt anybody. If your gonna turn them in you may as well turn your self in to cause your just a guilty blowing smoke at the dragstrip as we are blowing smoke on the road aint no different. If your gonna lecture us about smoking on the street clean yours up at the dragstrip.

If you read my post I said if you have to smoke do it on the drag strip or pulling track, not the street, yes Max'd Out will smoke when your on the line, it has massive injectors and huge turbos and it take a bit to light them. If it smokes going down the track then something is wrong with it. It is street legal but no fun to drive on the street at all with the race seats, roll cage, suspension and spool in the rearend. It is a trailer queen. I run a 550 hp tune in my daily driver and if you get on it quick it will throw a little puff but not much. I can tune it to not smoke at all. I don't intentially smoke anyone out, there is no legiment reason to smoke anyone out period. Yes I get pissed at tail gaters but I don't smoke them out, if I step on my truck it takes off not smoke. A little smoke doesn't hurt anyone you say, which one of they guys who wants smoke tunes is content with a little smoke? What I want to see end is these guys smoking out intersections and acting like idiots in parking lots at these diesel events. It's killing our sport. They are no better than those idiot ricers they love to smoke out.

If you want to call this a lecture then fine call it a lecture, someone has to get across to these guys that running a smokey truck is not cool. End of Lecture.

Well I can see where your coming from about killing the sport especially the burnouts thats just stupid to me i'm not big on the burouts. The way
I see it now that you said that is most of these people are going to the tractor pull or dragstrip and they see us spooling up and think hey thats cool lets do that when the event is over and then what do you know the whole parking lot is full of smoke. I catch your drift on that. But I'll be honest I like to blow smoke not all the time only on certain occasions lol

Also good point on the ricers lol I hate those stupid little things. They sound like ticked off bumble bee's running around

You hit it right on the head, and I don't know what to do about it. I'd like to see them get on the track in a sportman bracket race to try their hand at pulling the sled in a novice class, but most just won't. I don't have the answer. We need to find one though that is for sure.

end nothing...i started this thread to see if anyone made one cuz i know if i make one(which takes more than a single digital iq)i could probably sell it...and heres the thing u can complain all u want but the fact is not everyone is on here to see ur reasoning about not smoking...i understand what ur saying but its like telling people to stop smoking cigarettes, we all know its bad and in long worng is a stupid idea but tell me u've always done things by the book...yea i'm younger and when bullheaded but the fact is people are always gonna do what they wanna do so why not make some money off it...i understand that its a harzard for innocent people just driving, there are some days i just wanna roll a$$ tons of smoke and others i dont...i know its a waste of money, but its my money...and the next guy that tells me to just light a $20 on fire cuz thats all i'm doing i'm gonna pull one out and do it just to smight him...and all this thread started out as was a simple question, do they make one? why cuz after looking on youtube i noticed that all the trucks with smoke switches weren't LB7s and that i made one for my friends cummins(which didn't work cuz of to much upgrades)which is the same style turbo as LB7, if there was one for and LB7...and as for the legality of it, anything in a car nowadays is illegal...hanging a fricken air freshener from ur rear view mirror is a citable offense...and yea i'm sure it pisses off the tree hungers but they do just as much to piss me off its my retaliation....sorry for loosing my cool but seriously, its a 50-50 shot as to YOUR OPINION on the subject...and for those of us that do it one the street look irresponsible and those that do it on the track look responsible...doesn't mean ur any more right then me, smoke is smoke no matter when its layed...and i'm sorry i dont have the time to do efi where i can make mass power tunes that done smoke...and for making smoke tunes instead of complaining about people that use them why not go right to the source and complain to the people making em, supply and demand "You got the time, I got the dime"

and for the record i do sled pull, drag race and dyno challenge my truck...i admire u pro guys, u got me hooked...i just dont have the funds to build a full time truck but some day if will be...again sorry for getting heated

Well you cant stop everyone from doing it, it would be a impossible task. I know you wish you could. Now whats funny is I'm 22 yrs old and I drive like a 93 yr old grandpa I barely give the 2006 Dmax in my sig a 1/8 of throttle going anywhere I never get in a hurry at all (top speed 55mph lol) so my truck never smokes unless like I said "special occasion" meaning a sled pull or pass down the track same thing your refering to. You got my vote on people acting like idots thats for sure

i'm 25 and drive pretty conservative as fuel economy but getting on the freeway or the occasional bad day, i gotta just drop the hammer with my ppe on lvl 4 seems to get the best all around there

Ok Black Demon sorry to start a smoke battle in your thread. Proceed on and get your smoke switch figured out that way others can enjoy it no matter how much subman dislikes it like you said "people are gonna do what people are gonna do". But I do respect Subman's opinion and your opinion also.

Ok buddy cool down and lets get back to the thread I have those same bad days but I contain myself til I get home and hit the punching bag instead lol. Now back to the thread you said that you need a switch on th MAP sensor on the first page why not just unplug the sensor all together?

i apologize for getting heated...and i respect his opinion as well but theres to sides to everything...as for unplugging the point is to be smoke on demand, if u unplug the sensor it will smoke all the time with no power...i learned this my intake was clamped tight and the tube came out of boot...the truck had nothing cuz the maf wasn't reading right...i tried unplugging it once to see what would happen and the truck just lugged hit second and took off its kinda scary...so the point to the switch is when u flip it it messes up the reading in the sensor, so the computer thinks its got tons of boost and it needs fuel to balance things out...so then it over fuels cuz ur really not making any boost and thus creating tons of smoke...then u flip the switch the signal goes back to normal, so it only fuels what it needs from its set parameters...

I apologize for somewhat stealing your thread and bad mouthing smoke its is cool but there is a time and place for it ya know. But is is fun to play every now and then on a ole back country road which where I do most of my testing with tunes I write. Anyway thats kinda funny that the truck wanted to run away its funny but it ain't lol. I tell you what to try I know its not good but if you really want to smoke to the high heavens unhook one of your intercooler pipes and holy crap dude you'll be amazed with the ppe turned up at the smoke. You'll probably be thinking dang I didn't know stock injectors could dump that much fuel. lol

Ok being the certified diesel mechanic I am there are alot of ways to make a diesel smoke. 1. a really bad restricted air filter (hence put a clipborad over the intake or some kinda restriction) 2. Diesels run richer when cold (hence put a relay on the ECT wire to the ECM make the ECM think the truck is cold thus richer mixture) 3. Disconnect intercooler pipes (no air all fuel) 4. Stuck open waste gate will cause excessive smoke 5. disconnect the waste gate all together. Now here are some ideas I cant give all my secrets away but thats a few

I cant say there the best way to make it smoke and that they want be rough on the truck but its a way to make a ton of smoke.

More fuel and less air, achieved in numerous ways.;)

X2!!!!!;):D

Same thing I stated above take all the air away and what are you left with= FUEL!!!! lol

yea i'm not trying to kill my truck and the ppe smokes good enough i was just looking for parking lot fun...i heard that wrapping the air filter with rags to restrict air works too...and i saw a vid on you tube of a guy that disconnected charge pipes and its sounds really pissed off...and i'm not looking for something you'd have to pull over to be able to drive normal thats why something with fooling a sensor would work best and i'm not hell bent on doing this...it started out as a fyi do they make something like this...heres the video i'm talking about, yea it looks sweet but no way ever would i do that http://www.youtube.com/watch?v=1aWK6DlQ650

I installed smoke switches on 2 dodges today and it really worked!! We are now looking for a diagram to help us put one on a 2005 Duramax.

I know buddy I'm just trying to help you out as much as I can

actually a friend of mine who is an engineer came up with an idea...find a straight section in the charge pipe and get one that is the same size but in steel weld in a bung and put in 3/4 electric solenoid...flip switch solenoid opens to bump boost out makes smoke, flip switch off close solenoid normal driving cheap and easy to make and install...he thought of this after i mentioned what u said about taking off charge pipe...we can up with some other ideas but that one seemed to be the "best"...and when u dont want it just put stock pipe back in and no one is the wiser

Usually the waste gate is popped open to relieve overboost. Is there a strong enough solenoid to pop open the wastgate so boost remains low?

Man, if you bathed a white Honda in that cloud, the driver would have to wash it with Comet to see the stock paint again! :D

yea the solenoids that we found cheap on line are from a company that sells air bag equipment...an i mean like car hopping air bags not truck air bags...they have to be quick release in order to slam car to ground...and this solenoid would go in charge piping as to release boost before it hits motor...and we thought as a joke pipe that out the side of truck so it sounds like open compressor line

Someone has to say it so might as well be me. Making smoke is just plain dumb. Not only does it give our diesel trucks a bad name, it's illigel, will get you a ticket, is hard on your truck, and make it more difficult for all of us to get our sport accepted by the general public.

What exactly are you trying to prove other than you have a single digit IQ by making a bunch of smoke?
I'm With you Smoke Cost's Money and is wasted money

Ok Black Demon lets get this smoke switch figured out so ya'll can have fun blowing smoke. No matter what else is said on this thread we'll get it figured out.

well i looked at charge pipe and there is no straight section and its alum. pipe and is probably expensive...plus i dont have a way to weld alum. anymore...but i might be able to get one bend up at exhaust shop out of exhaust tubing then weld the bung and put solenoid in it and see that seems to be the cheapest and easiest i can think to let off boost fast

what a great thread. myself i like rollin coal. there is a time and place for it. if ya get er figured out i will absolutly try it!!!

any got a "smoke switch" on there truck? was reading a thread on here and it seems to work on LLY or LBZ but bot to sure on LB7...


Black Demon any update on the smoke switch????

the lb7 has a vacuum or pressure operated wastegate..... no? not shure ecactly which 1 but its not comuter controlled soo it opens and closes depending on the speed of the turbo soo No a smoke switch isnt possible on a lb7 . if you are comparing 1 for a lly lbz or lmm, which is a computer contolled tubo if u want smoke get a PPE hot+2. i just tried 1 on my truck from a friend and besides my low rail pressure 99% of the time and the stalling it def wasnt Obama friendly... LOTS OF COAL rolling... and im not talking clean coal either!!!

Just wondering how far along you have gotten on this. Im extremely intrested too.

taking the idea of disconnecting one of the tubes. what about using something similar to the exhaust bakes and plumbing it into the boost tubes for the turbo thus shutting of exhaust supply for boost. probably expensive but an idea.

but in doing that wouldn't you put too much strain on the turbo by blocking the flow??

yes but maybe it could be adjusted to where it doesnt completely close off air flow, just like a damper for it

any updates ?
