[QUOTE="Charles, post: 1521188, member: 103"] I have no doubt it would do perfectly well. I imagine it might spool a bit slower than a 38R, so out of the hole it might show that a bit, but a compound truck is [i]rarely[/i] under the chargers... so I doubt it would be a big deal. I don't know what kind of boost those can take and stay together, but you'd want to be careful during initial setup that you didn't accidentally hurt it as it might not be as forgiving as the 38R to say a blown wastegate signal line and running 55lbs as a single for a sec. Although with compounds any initial foo-foo can get out of hand with triple digit manifold pressure coming faster than you can imagine, so engine block might be an issue before the charger anyway... Conceptually the chargers don't necessarily "work together" as much as the second stage (small charger) compresses air into the engine and is sized for that engine in the range of rpm you intend to operate, whereas the first stage (large charger) is sized for the resultant "engine" that is created by that second stage charger. For instance, with say 20lbs on the engine from the second stage, you might as well have the first stage hanging off the side of a 950 cubic inch engine, because to it.... that's what's happening.
