I got my gauges in, and my EGTs are crazy high. With no load I could get that bad boy up to 1350. I was freaking out, I mounted the prob pre turbo. I bought the truck with the injectors in it and have no clue what size they are now. I was planning on doing a plate and 3 k spring kit, but I think i need to cool it down first. Am I on the right track and if so where should I start. (I have a stock intake box with a drop in K&N)

 

Sig says 215 injectors... true? sounds to me more like 300's...

 

Nothing wrong with 1350 provided it doesnt go higher.

 

Not sure now...They guy I got the truck from told me he had them replaced and was not sure, but it could have been this could have been that type of thing. Should I pull one out to see what it is?

 

I'm not sure that would tell you. AFAIK, the only way would be to get the flow tested.

Given the price of Bosch 12V injectors, I'd just buy some 300s to be sure.

Towrig,

You sig says 4 inch is that a full exhaust, if so then the next thing is to get some air in the engine, the stock air box no matter what filter is marginal for a stock truck much less a modded one. Get a Pro Guard 7 intake and it should help with the EGT's and let the turbo spool up a bit faster as well. We stock the systems and will be glad to help you, call us if you need to.

yes its a full 4 inch. I was thinking of intake. How much would this help? I am afraid to put the Yota on the trailer next weekend after seeing those empty EGT'S

 

Is 1350* your peak EGT, or does it stay there? A peak EGT of 1350* isn't that high. Even with my mods, I can still peak at 1450, but it doesn't stay there.

 

Towrig- Another problem for you out here is the altitude. Stock turbos just can't keep up with moving the air thru the engine- especially if you have bigger than stock injectors.

I wouldn't be too afraid of towing your rig.
Now that you have an EGT gauge, just keep an eye on it and modulate your throttle to keep the temps reasonable.
Like no higher than 1250* for extended pulls.

I HATE having to back out of the throttle when pulling long high altitude passes, but the only cure is a new $$$ turbo.

 

Thanks for the info, Yeah I tow over Ute and Wilkerson pass all the time, and Go up I 70 out to Moab. I am leaning on the cold air intake and then I will start to save a few bucks and see what Santa brings me

 

Mark Craig is right you need a better intake mine was real High then I went to a k&n in the stock box and that helped a bunch then I went with the scotty II and that helped even more.

19-20 pounds Thats it.....

 

Try clamping your wastegate or get a boost elbow.

 

yep, try clamping the wastegate hose, then get the boost elbow if you need to adjust the pressure. i don't know what elevation you're at in colorado as it seems to vary a ton, but don't run over 32 pounds of boost at 7200 feet (guess it from there + or -). remember, i lost 8psi from sea level up to 7200ft, so at 7200ft 32psi equals 40psi of boost obviously...i wouldn't push an hx35 beyond that since it's only creating heat past 35psi sealevel anyways.

Timing would help if you haven't done that already.
