"Got a Holset H2C from work and was wondering if it would work well on my truck, as in more or less boost and spool time.."
- The H1E is the early model HX40. The H2C is off a semi engine. Massive exhaust housing. As a single charger you couldn't spool it. It has been used in twin setups before.
- yeah it came off of a Cummins L-10
