If you want to do a standard performance build you are stuck. As you know, there aren't many off the shelf "performance" parts available for these engines. There are some things that I would suggest, but they take a lot of... time I guess you could say.

How much time/money are you willing to put into it? *cough* my signature *cough*

I currently have a Heath GLE, I was satisfied with it for the 3 months I ran it.

Turbine Doc, I mostly agree with your statement as it applies to stock manifolded engines. But, in an engine where other options of making power have already been exhausted, and someone is trying to get that little extra edge, there is room for improvement. I wouldn't take anything from many...

mr goodwrench 06, I took got all my specs using a Comp Cams professional degree wheel kit. I took all my measurements at .050" off the seat, as this is the industry standard, and makes it easy to compare camshaft profiles to ones that are already produced. I checked everything over 7 times, took...

Thanks aka diesel driver, I called them too, and sadly they receive them from Canada, but are cast in China. Places tend to give you the truth when you tell them how high profile of a build you are doing. That's when you find out what they are all about, is becoming a real eye-opening experience...

Grr.... I'll change it. Edit: fixed :)

Mind if I add a picture of mine installed, using this guide of course :D I'll get new lenses when I decide on the colour I want :)

I think you right, it must have been too early in the morning and I obviously read it wrong :mad2: I was going to get my heads from them, but as I found out, their stuff is cast in China "with whatever metal we send over there" is what I was told. I like to know what grade the material is I...

I think you got it backwards, the factory precups are non-magnetic (300 series stainless is the most likely alloy group) The aftermarket precups are magnetic from what I have heard, and it sounds like they are a 400 series stainless (which generally has a higher chromium content among other...

A tuning tool that I like to use (made by a company that has lots of experience in EFI tuning) recommends IIRC a 16:1 AFR for diesels at WOT. Maybe it was 18:1... I forget exactly.

I am copying and pasting my post from the other site here, as it cleared up a lot of things for people, and I think it describes it very well. While valve overlap CAN increase power, in a stock engine like the 6.5, with very restrictive exhaust manifolds, increasing overlap is bad. I'll try...

:ugh: I guess I missed that, having three conversations at the same time :lol: But engine temperature would be more manageable, because no extra fuel is added, and the "extra" power is simply being unlocked, it is already there to begin with, just being wasted :)

No need to increase valve lift for the average performance build, is it more about pressure differentials. Without getting into a big long post, there are massive pumping losses on the 6.5 diesel, and they can be overcome. Stainless steel pipe is more reliable than cast iron, and setups that...

I build custom headers :) And there is someone working on them that is almost done. :thumbsup:

There is plenty to be had with an aftermarket camshaft in a 6.5 turbo diesel, provided you loose the insanely restrictive exhaust manifolds. There is a reason the factory camshaft works so well, it is because they designed it to match the bad manifolds and exhaust setup. Take that away and the...

I was going to get the well nuts, but they were $8 a pack :o I tapped the factory stainless screws into the sheet metal. Also I found out where to put my factory plug for my clearance lights into the block under the dash.

I am glad you asked :D http://www.dieselplace.com/forum/showpost.php?p=3393233&postcount=136 I am working on a custom billet camshaft right now, but the specs for it wouldn't be useful to any of you guys/girls anyways ):h

You are correct :)

I have considered those, but I doubt they will hold enough horsepower either. The 599 is supposed to have the thicker cylinder walls ect. but I am doubting it's ability to hold so much horsepower in. Bolt hole sizes don't matter too much to me, I'm getting either a one piece cast or billet...
