I don't have one for sale but can tell you about spool up. It's a non-issue with mine. I have a BD power HX40 turbo and it spools up real fast with the mod. s I have. There is no lag at the low end and the high end is unbelievable. I have to agree that your probably going to need some type of fuel enhancement for good HX40 response, it will probably be a dog at the low end without the assistance of bigger injectors or a fueling box, at the minimum add a Edge EZ or equivilant. If you don't have the BD 4" e-brake, your gonna have to upgrade as the down exhaust pipe from the turbo is 4". I think it would be self defeating to attempt to place a 3" brake into the loop with a HX40, it's meant to be used with a 4" pipe turbo to tail. With my rig, I see 40 psi's of boost at WOT, my turbo is wastegated at 45 psi's.
Hope this helps.
