damn if you were close if slip in a little tune on that truck :D

x2 on tell him to put up some cash or shut the hell up.

:booo::booo::booo: not worth it even if you could beat him he must watch the show pinks and has an ego the size of texas.

Don't do it, check out the june issue of diesel world. The 8.1 is a monster. def get efi live or ppe before you mess with that sh t biscuit.

just an update. I did not get to race him bc he traded it in on a nissan altima! LMAO

Well thats funny!! I had a 8.1 for about a month after my powerstroke was stolen and it hauled ass. It would burn the tires at a light and it was stock. I raced my buddies 6.0 with a edge in it and i beat him with my stock 8.1.....

no replacement for displacement:tu:

holy shi--.....They're honestly that fast? They're at 340hp 450ft-lbs of torque IIRC...I thought the duramax or a powerstroke would be able to trump that. Similar horsepower but way more torque.

I think it is the fact that they dont have to wory about turbo-lag. I cant wait to get my PPE! Hypertech=sucks

The 8100 (thats 496ci!) gasser can be absolutely brutal with some tweaking. Keep in mind the marine versions of it are rated as high as 500hp! That's in a factory engine with a warranty! The power is there. It's all in the ECM tuning. Buddy had one in a 2500HD with the 5-spd manual trans and 4.10 gearing. Everything stock except a straight-piped exhaust and he could get rubber through 4th gear.
