He pulls DHRA Work Stock and was points champion last year. It is rumored that he is the one with a modified stock charger simply because, as you can see, his truck runs like a raped ape! I have seen his truck get teched and it passes. I don't
think the DHRA can enforce an inducer limit on the Work Stock class cause it just says stock appearing charger. Also, his truck smokes white at idle even on hot n humid summer nights and doesn't clear up after running a while (warmed up). Not sure what all is done but its not just bad injectors smoking.
He almost certainly has engine work done, I just don't know how much. Someone does though, and I'd be willing to bet someone on here knows simply because there are only a few places in the country to get certain pieces and I'd venture to say, he has them on that truck. I'd just like to know how his susp. is so dang rigid that it pulls a wheel. He has to have upward limiting straps on the front end. I know people say it causes bouncing but his don't bounce and that damn tire was off the ground. I don't know about you all but it takes quite a bit of jacking the truck up to get the tire off the ground on my truck and I can't imagine the frame was torquing that much to get that much lift to pull a wheel like he did.
Back to the charger... I only have heard of and confirmed one other Duramax that had a modified stock charger. It had a larger inducer wheel swapped in along with some housing work (eds04dmax on TDP). His truck also ran really for a "stock chargered" truck. You just couldn't run that charger in a 2.5 class like you see a lot of now because its a 2.6x" inducer "stock" charger IIRC. Otherwise, I'd have it.
