how can i raise my boost pressure to burn extra fuel added 3k gsk and 100 plate and got lots of smoke i don't mined smoke but i'll probably get a ticket for this.

 

An adjustable boost elbow (TST) will delay your wastegate opening and allow more boost. But you will also need less restriction in your exhaust and maybe a BHAF to take full advantage of this. If you don't get a pyrometer you will melt a piston with your new 100 plate. A boost gauge will tell you a lot about how your RPM, gear ratio, EGT, throttle position, and turbo interact with each other.

 

i have the wastegate unhooked do i still need a adjustable boost elbow? The exhaust is straight piped.

 

no an elbow won't help with an unhooked wastegate. and really if it's the stock turbo it won't reduce smoke all that much with a 10 plate and the afc messed with. adjust the AFC until you minimize the smoke. And do what Rare suggested, get guages. all that extra fuel makes for ALOT of heat. When I had just a plate, the afc moved and the stock 35 I could get EGTs way up there pretty easily. Max boost isn't always best either. a 35 at 40psi isn't making anymore air than it is at 30psi, just hotter air. So maybe you should hook the wastegate back up and get an elbow to raise the boost but limit it as well. Makes is less dense and raises your EGT's otherwise. Back off the plate and the AFC until you get guages. Or just keep your foot out of it.

 

I don't know. Get a boost gauge to see where you are now. Make mods one at a time to see what the effect on boost is. You can't "feel" boost. You have to measure it. With an unhooked wastegate you might get overboosted (?) Too much turbo RPM and wasted energy. Others know more about that than I do, but I think boost must be controlled.

 

ok thanks but i got one more question, what is that other tube coming out of the the back of the afc housing running into the side of the engine right below the intake elbow?

 

That tube carries your boost pressure into the AFC so it knows what to do. The AFC controls fuel up to 6 psi boost, then the fuel plate takes over. I don't understand it so others will have to explain if you want details.

 

will bumping the timing help with smoke problems? sorry for all the questions.

 

Yes..

the timing of the pump will more efficiently burn fuel, with the 100 plate and the GSK a 16 degree -17 degree timing will be best, BUT i think that you will need along with the timing a better turbo, ihave ran the 100 and the zero with the stock turbo, and EGTS are wayy to hott if i get on it, and at all speeds there is smoke out the pipe.. so a better turbo if you can afford it wouldnt be a bad idea.. anything over 35 psi on ur stocker is just blowin hot air..

You must at least get an egt gauge on your truck now!! You are playing with fire....a #100 plate on a 215 pump has the ability to move more fuel than what the stock HX35 can handle at WOT.....you are driving blind without knowing egt's.....fuel is what makes more boost......if your wastegate is blocked and with your fueling level, you will be boosting past 35 psi and out of the efficient range of the stock turbo.....no point trying to raise boost if you don't know how much boost you have now.

 

so when i get the gauges on and im boosting over 35psi the only way to get more boost would be to get bigger turbo or hybridor twins. if i can get 35 or 40psi out of it that should be plenty of boost with a 100 plate 3k gsk.

 

ID say with the hybrid,

or a good high tech turbo, that should fill your needsa nd put you up there in the higher HP area, id say ud be close to 400 or so, add some 370s and some delivery vavles and u might hit 500,

500 would be great plan on pulling sleds with this truck.

 

100plate full forward, 3k, and no pyro? You've probably 1/2 melted the pistons already...

 

More boost isn't necissarilly what you want. If your pouring out the smoke at 35psi of boost you need more volume. If you can increase your boost efficiently then you get more volume, or you can get a bigger turbo that can move a greater amount of air at the same psi. Either way your going to need a bigger turbo to get enough air to burn the amount of fuel your injecting.
