SB,

I'll have to look at that issue. However, I am not looking for that much out of my truck. Maybe I'll go from my 90 HP module to the 125 HP module, but definitely not the 140 HP module.......................well, maybe the 140 but there's no way I'd think about the 215 HP module.......................check that, maybe just the 215 without propane or nitrous.......................

There is a guy that posts on The Diesel Page who has ran 12.49 @ 105.37 with just boxes, and 11.95 @ 111.46. I don't remember if that pass was with just one 215 HP box, or if he had a couple stacked. Getting the HP out of the engine is fairly easy and relatively inexpensive, but there is about a $6K bill to pay to get the Allison properly beefed. Also, I'm not sure how he keeps his front end under his rig. Full boost launches in 4WD can't be the best thing for the factory CV joints and tie rods.

Here is the link if you are interested: http://forum.thedieselpage.com/ubb/ultimatebb.php?ubb=get_topic;f=3;t=007149
