dieselpower04,
there are three reasons that we've seen that people don't feel a major difference.
1) They are already running way up in the HP, like 190's and the difference is not something you can FEEL. Even if the cam does add some HP, it's not percentage-wise, enough to physically feel it. I know you didn't dyno the cam.
2) you've run to the limit of what the injectors can supply. Isn't yours is the cam installed by Krout? Both he and I discussed this with you and it appears to be your particular problem.... you failed to mention that. I don't think your claim of 'no performance gain' is fair assessment when you exclude that bit of information .
3) The torsion value needs to be altered as much as 4.0+ to -6.0 to find where your engine runs best. Unfortunately, the crank lock has about a 1-2 degree inaccuracy. That will change where the camshaft degreeing needs to be set in order to maximize the performance of the cam.
In any case, your cam was toast and you needed a cam change. If you upgrade to the larger PD150 injectors, I am sure you will see the performance improve, but first, you need to experiment with your torsion value (VCDS/ Engine Module/ Block 4/ torsion value). The adjustment is about as fine as that of the ALH/ AHU's injection pump. A small movement can make a lot of difference.
I personally recommend moving the cam -2.0 points, running for fuel economy and check power, then move the torsion value +2.0 points and see what works.
It would be nice to make the torsion value setting more scientific, but until there is a decent way to find TDC, some experimentation is required.
I hope that gives you some basis to work for improvements on your cam setup.
Other than that, since you had your cam install, we have created a BRM injector profiled cam. The BRM injector lobe has a higher lift and it may be able to provide additional fueling for those who want 'all the beans'. Since we have created an improved oiling to the cam followers, we feel that the higher lift of the BRM should not be a wear issue when the cam is reprofiled and chrome-plated.
Other than that, be aware we are already catching flak for 'adding a wear coating' and the claim is that it's not needed. Isn't that a surprise... from the same ones that take over a year to come up with a cam...
Chrome-plating does raise the hardness to between 72-74 Rockwell, but that is not the only value for the chrome. It is also a great heat transfer medium, it is smooth as silk and the abrasion resistance is higher than the same hardness steel. It is a well-known performance addition.
