Talked with the previous owner of my truck the other day about how much my pump is turned up and the high egts. He claims 5 1/2 turns. Thinking about turning it back down some until I get my water/meth. How much should I turn it back down?

 

i would install a big intercooler before i turned my pump down, with that big turbo and not enough fuel it wont be fun.

 

Well, If you have guages I would back it down untill you are happy with all your readings.. Every truck varries, Back the full pwr screw out a turn or two, re adjust idle.. Take it for a burn.. Do that untill your happy..

Most of the trucks that I've messed with there is about .700 from the end of the pwr screw to the backside of the jam nut. That is a stock truck. 2-3 turns in puts it at about .550 to .600 out.. Then the low idle is usally like .200-.250 out..

Here is a link to one of my Dynos. I think it is too much fuel right now it dumped that from half throttle.

 

that didn't look like very much fuel, i think you could tune that out with the afc, and i ment you wont have enough fuel to spool that turbo if you turn it down

 

That smoke looks fine.

It clears up fast, thats about normal for a stock injectored truck with stock fuel pin.

In my opinion I think you may have an epic boost leak.

You have all that turbo with stock injectors and stock fuel pin and you're even talking about turning the pump down...something just don't sound right

Is that a 62/71/14 or 62/65/14

 

I checked all my IC boots and they look fine. It hits 42 psi and blows the waste gate no problem. I dont want to turn it down, but I dont want to melt it down either. I know if it is a 62/65/?? the only options it shows on their site is for a 14 cm or 12 cm turbine housing. The previous owner installed it. I would guess by reading the site and the moderate fuel upgrade he went with the suggested 12cm housing but not sure.

 

I really want more power and plan to order a water/meth kit in the next few days along with a fuel pin, but I will be pulling my boat on a 2 hr trip for the 4th and dont want problems with the egts. Dont think it will be pulled it on the highway earlier and only got to about 950 after the turbo and that was lugging on a slight grade it to see how hot it would get. Just wanting to get an idea incase it starts getting hot I can pull over and back it down some.

 

how hot does it get on a 0-80 run? egt wise

 

No trailer? 8 or 9 if I am really getting on it hard! With the boat I didnt get in a hurry, just ran the gears up and shifted and got 800-900. After I got to a cruising speed it came back to about the normal 600-700 range. It really only heats up if I dont spool over 10-15 psi, anything under that and it rises pretty quick. But with a trailer of any size I see no reason to get in a hurry.

 

before of after the turbo egts?
and you have 4:10 gears right?
i think with that turbo you have to keep the rpms up to stay cool, how is you intercooler working?

with what i have i can hit about 1300* pre turbo with the trailer on by 55mph lead footing it. i think i have 190 injectors and my fuel screw is in untill it stoped.

with that big turbo you should have any issues with heat and stock injectors

 

The pyro stinger is right after the turbo, as close as you can get it to the turbo. Right after the pipe connects to the trubo. The PO was confident in drilling the manifold. I plan to relocate it during the meth and fuel pin install. And yes they are 4.10 gears. Dont know how well the intercooler is working. Dont have the resources or knowledge to check it. How would I check to see how will it is working.

 

i bet if you move that pyro prob it will run cooler at cruise speed but it will climb fast when getting up to speed.
i would invest in a bigger intercooler before w/m

 

Pressureize the Intercooler system. GEt a spray bottle of soapy water and spray it on EVERYTHING with about 30 psi running through the system.

And here towards the bottom of the thread https://www.dieseltruckresource.com/...ze+intercooler

IF you pressureize the whole sytem all you'll need is a Boot the diameter of the turbo inlet with a peice of PCV pipe clamped in it with a valve in the end so you can hook your air hose right up to it. Hook it right up to the front of the turbo (inlet).... (SEE PIC BELOW) BE sure to adjust your air compressor regulator down to 25-30 psi, as soon as you hook up the air line to the pcv pressure tester, it will start pressurizing until it hits whatever its set at.
