12v Turbo Maxing At 17PSI
 

i have maxed my fuel plate and maxed my star wheel but turbo is maxing at 17PSI anyone to help would be greatly apriciated

stock thats about where the wastegate is set, you need a boost elbow to get any more out of it

if i order my #5 fuel plate like i was planning will it come with an elbow and does the elbow go infront of the wastegate or were can i get an elbow

depends where you get it from, on some of the trucks it goes right on the compressor housing and on others it goes right off the afc housing

like right were it hooks right into the the neck then were do you conect it from there

if you have one coming off the compressor housing, a boost line that is, it will be on about the 5 o clock position on the turbo if your looking at the front of it, it will be a little brass 90 degree elbow, if not it will be on the back of the afc housing

there is no elbopw on the turbo at on the back of the AFC it is a tee fitting

you will have one of two on your truck either a barbed brass elbow on the front of the compessor housing, or a straight brass barb in a "T" off the back of the AFC housing next to the boost line that goes to the intake manifold.

The boost elbow replaces which ever you have and limits the boost to the waste gate. It should come with most plates that you buy, or most shops will sell them for about $15(TST, PDR, Source Automotive, ect...)

Here is the instuctions for the TST plate it has little diagrams that will show you where it goes, figure 2 is compressor, figure 3 is AFC. http://www.tstproducts.com/pdffiles/INSRUCT98.pdf

so if i put ithe elbow in my compressor housing at the bottom like the picture do i just conect that hose to the wastegate and fully remove the one from the AFC to the wastegate

you can either swap the straight barb for the elbow.

or drill and tap your compressor housing, install the elbow, run a rubber line from the elbow to the waste gate, then pull the metal line and straight barb off and install a plug where the barb was.

that doesnt seem difficult now on that elbow is there an alen screw in it to restrickt the flow

depends on what brand you get, if it says "adjustable boost elbow" yes.

I know TST's used to, but not sure now
I know BD's does cause thats what I have
I know Source Automotives does

Here ya go http://www.sourceautomotive.biz/inde...ge=shop.browse

can i go to the local napa and pick up a ajustment valve that does the same thing for now

You might be avle to make something work, but for the minimal cost of a boost elbow I wouldn't waste much time on it.

However as long as you have a boost gauge and you keep it under 35 psi, temporarally you could disconnect the boost line to the waste gate and plug it off. But at the same time without pushing more fuel to it don't be suprised it you don't see 35PSI.

IF he is trying to run that kind of pressure and use the stock fueliing plate it will not see 35lbs of boost.He will need some type of fueling plate to get the bigger boost and no amount of just restricting the gate will give it to him.Fuel+Air=Power.

I would also make sure the wastegate is functional as I have seen many older 12v's with the gate frozen open and no matter if you put a plate in or not they do not build boost.

no my wastegate is not frozen it works great for the past few days i have driven with my wastegate crimped and it has made it so instead of maxing at 17PS! i can get her up to 25 without breaking a sweat but that is not enough i am going to order a #5 fuel plate, 4000 GSK and 370 stage 2 injectors so i think i will make 35PSI

Just make sure you install the boost elbow when you get that other stuff, with that much fuel you will likely overspeed the turbo!!! Stock turbos don't like morre than 35psi

Also you do have a pyrometer correct? that much fuel will likely push EGTs through the roof with the stock turbo!!!

HAVE FUN....Josh

ya i got a pyro,boost,trans on the pillar fuel guage in the dash, oil temp and diff temp in the overhead so i like to listen to my truck when she is talking to me

Boost line
 

Make sure the boost line that goes to the back of the AFC isn't crimped, I had the same issue with my S300, and I found that my boost line was crimped and not supplying the neccessary psi to my AFC to move my AFC arm all the way forward.

well i have a line comming from the intake manifold that also gos into the AFC so im not worried about that

Bud you need to wait a couple weeks so you can buy my turbo and the you will max at 60psi.

well i might just have to do that that turbo would be great in that truck i had a fealing that 11secoundcummins was your name i seen it a few days ago

Your pickup looks good in the snow bud.
