Capping the entire intake side. From the turbo outlet to the intake horn. This will tell if you have a boost leak. Might want to also check your radiator for blockage. Look between the rad and the ac condenser. There is usually some blockage from the puke bottle mist.

 

You didnt happen to add a brush gaurd, or "cow catcher" to your front end did ya? Some of These can raise both EGT's and water temps due to the lack of air flow.

As stated before throw about 20-25 PSI through your intake. Its possible you have a cracked intercooler, also. If you cant find any leaks, then I would say you need more air. I can reach about 1250-1300 degrees at WOT with my mods listed below. Pushing about 27 PSI with the factory charger.

Another thing that is easily looked past is the ambient temp. Now that the cool weather is over and is Hot and humid this does have a slight affect on your temps. Especially when towing heavy...

Good luck!

 

Ok i got a EDIT load of soap and poured it on every part of the turbo to the intake. I have a Huge leak where the 3 piece ATS manifold meets together. Would this cause high egts?

 

I doubt it, the only way would be if it's loosing so much that it's not driving the charger.

 

These are the leaks on the ATS manifold that was put together by them and powder coated. I would assume this would make a difference in the egts, seeing that the exhaust gases are escaping through these holes and not going in the turbo?

 

Are you seeing more black smoke out the exhaust pipe?

 

I have not noticed anymore smoke, I have not paid that much attention to that area. Whyy??

 

Lots of black smoke means you need lots more air.

 

I would guess boost leak, or the tranny is going away. Is your E-brake stuck on

 

How about a bad injector dumping to much fuel.

 

Injectors are new and the tranny has been rebuilt!!

 

If you're getting more black smoke than you used to, it's a sign you have less air available to burn the fuel you're putting in.

I doubt those leaks on the exhaust manifold are causing your problem. Based on the pics, I don't see any soot marks on the manifold that suggest a leak while running. If that test was done cold, the contraction of the metal would allow small leaks that would be sealed when the engine is running and the manifold is warm.

Only being able to pull 30-32 out of the HX35 does sound somewhat low. Are you sure that your wastegate isn't opening prematurely? In any case, 35psi is pretty much the limit for the HX35 and based on your fuel mods, you do need more turbo.

 

But it should not be leaking at all, and if it is leaking your not pushing all the air to the turbo which you should be. Thus causing high egts and lower boost. Dont you think??

 

I've never run a multi-piece manifold, so I can't speak from personal experience. Having said that...

I would expect that a multi-piece manifold would have leaks when the metal is at ambient temperature. The places where the pieces intersect would have some looser clearances to allow the pieces to move. When you start the engine and start flowing warm air through the manifold, the pieces will expand and seal off the joints.

In any case, if you had a significant enough leak to cause enough drive pressure drop so that you couldn't spool the turbo fully, I would expect to see soot stains around the leaking areas since you would have soot escaping through the leaks when you're rolling smoke.

Have you been using the BHAF as your intake the whole time? Are you running a heat shield on the BHAF?
