I'm assuming that you have cowl induction. Have you modified the underside of the hood in any way to direct air to the turbo? Any problems with rain? Has anyone modified the air supply snorkel to gain greater air volume?
What are the best methods for increasing air volume delivery to the 6.5TD?
I had a 4inch Harwood fiberglass cowl scoop molded into my factory hood by a friend who has a body shop and I think it looks awsome. The reason I did it this way is because all of the aftermarket hoods dont have the bulge in the front that the HD's have, plus I think 4inches is a lot meaner lookin than 2 1/2........and I think that bulge is what separates a Hd from a 1500 in looks (unless you have a GMC then you dont have a bulge to begin with)......from the font anyway........Cost was about the same as buying a whole hood and getting it painted.

I'm pretty sure Ratdoc has the steel Goodmark you posted above. Looks pretty smooth, check the CT Dyno Day III pics for pics or ask Hootie if he has some. I really ment for you to buy his stock hood though.
Hired Gun - Reflexxion just started shipping the cowl hood for the 03-04. The have two other versions that may have shipped or will soon.
As far as fiberglass, I have yet to see one that lasted more than a couple of years without problems. I've seen them warp, and in a couple of cases the top layer delaminated. Going down the highway losing a 5x6 chunk of Fiberglass is not good. There may be some good glass hoods out there but if steel is an option, I feel it is a better choice.
