Yeah I see what you are saying, that's why I suggested maybe you have a blown up pipe, boost leak ect.
You installed a wastegate at the some time as the cam? Did I read that right?
.
Ive been saying for almost 2 years, even after i installed a cam on my 08. There is no hard data on how beneficial they are, or if they are at all on a stock turbo truck. Whether it be a stock regrind or a billet cam. I will not be doing a cam on my current truck build for that reason. Plenty of big numbers out there with stock valve train.
like I said I think the biggest benefit of a cam in these trucks is it holding power through the curve instead of dropping off at high rpms. people with stock turbos probably wont notice it as much as someone with bigger set ups.
You are completely right about that, I could careless boost dropped off but I feel a loss of 6-7 is a big drop, plus if it was moving more air my egts would be down when I was pulling
I would think a cam does the same thing on diesel as it does on a gas engine.i wish i knew more about cams to say what duration effects. maybe jared or tadd will chime in.
That cross over pipe for the EGR started leaking on my truck. I would check it. They are fun to get off with the cab on.And that hissing is probably a up pipe or the cross over pipe for the EGR on the exhaust side that's what mine was and is doing around 1800rpms you can really hear it start to hiss
There is a huge diffrence between gas( natural aspriated) compared to turbo charged. You will find that If you went to put a turbo on a gas motor there is diffrent cam grinds for turboed motors. What makes a huge diffrence on a non asp motor might not make much or a diffrence at all on a turbod engines.I figured they make a difference in gas motors and I haven't really heard of anyone putting them in a powerstroke so I figured I would try it
And that hissing is probably a up pipe or the cross over pipe for the EGR on the exhaust side that's what mine was and is doing around 1800rpms you can really hear it start to hiss
What tuning?
Hellen Keller sent this?
Were there any tuning changes to take advantage of the cam? Most cams broaden the RPM as well as carry the "redline" out further, so if your tune is trimming fuel where the stock/canned parameters tell it to that could make all the difference.
I didn't read the whole post just the first page but here is my story. I bought a cam from a diesel company when I was having my engine rebuilt. The people rebuilding it profiled the cam, had it checked out to make sure it would work with my diesel engine, and the results were not good. The camshaft was made like a camshaft for a high revving gasoline engine. It was no good at making power in the range that diesels make their power. I think this is a problem a lot of companies are having. They are getting people to manufacture their camshafts that are used to doing cams for gas engines and don't understand the way diesels work and where their powerband is an such. I don't think its the companies fault that's having them made it just the lack of knowledge of the camshaft manufactures that are making them. Anyways I did not use that camshaft and had a custom camshaft made from a company that understands diesel engines and made me one that would work in my rpm range. Just my story.
thats somethign that matt would have to answer, he said he might add some fuel up top, but idk what else was done to the tuning
