Thats haulin some serious "A-hole" for a 2500HD!! Good luck, hope you do it!

 

lol, i just threw that number out there semi-randomly. My bone stock 6.0L with a whipple made 416/478 and ran 13.06@102. Not sure the extra 300hp will give me an extra 1.5sec but how cool would it be for my big *** truck to get kicked out for not having a friggin roll cage, lol.

 

For comparison's sake, my best in my truck is 11.63 @ 119 with a 1.80 60 foot. That's at 15 psi with methanol and a -240 something DA on the track that night.

 

Problem is he has about another 1200lbs on your truck, maybe more. I think the fasted 2500HD is stil a DMAX. I think it was BMDMAX with a 11.9X or something like that.

 

Michael Tomac has went 11.4. I'm not sure if he posted it or not though.

 

Cool! Got any links or pics or anything? PM me so we dont "F" up DenaliHD's thread.

 

Yeah that's why I posted up....it will take a lot more to make his heavy truck hit mid 11's. Maybe some spray coupled with the KB

 

For what its worth my KB has been good to me, I also dont have a problem getting ahold of them.. They used to be impossible to get ahold of however I havent had a problem do so for some time now. Mine is only a 2.2L compressor and I have had it as high as 12lb on my 6.0 Without the big air to air intercooler it would be even higher. I still can drop down 3 pulley sizes as well so that would put it at 15 or so I am guessing (assuming no belt slip) I would really like to see how the 2.8 does on a 408 and will be waiting for your results....

 

not really sure how much boost or how much HP to expect out of the kit as ordered. I have a 7.25" crank pulley and i ordered a 3" and 3.5" blower pulley. we'll see soon enough.

 

Best of luck to ya, you could always jump up to a 8" crank pulley. I have thought of doing so that way I dont have to run as small of a blower pulley.
