how can i get my turbo to spool faster?
i have a L76 6.0 engine. ported 317's, tick 226/235 .605"/.610" 115+2 turbo cam, and a masterpower t76 with a .96 a/r. Im currently getting full spool around 4000-4200 rpm. around 10-11 psi. it pulls like crazy, but id like to get it to spool a little faster if i could. i currently have dual 3" merge coming off the headers. I did some reading that changing from 3" to 2-2.5" pipe merge would help with spool up with out sacrificing any power. any other tips or tricks i could try? i know its not a big turbo compared to some of what you guys run, figured it might spool a little faster. thanks!!

With a 76 You could run a 2" pipe without sacrificing any power. If it was a billet 76 you might want 2.25" just for some headroom, but you won't be needing it with the master power. I would drop to 2" and wrap the hot side. Your spool should pick up considerably.

you are having trouble spooling a single 76 mm with a 6.0? something is VERY wrong.
also, how responsive are you looking for? i mean an NA 6.0 is freaking torquey even without a turbo.
if you want somewhere to start, look at timing, maybe looser converter, or if its just too slow- add nitrous.
good luck

3" crossover is one mechanical reason. Thats a massive reduction in exhaust velocity, the exhaust is hitting the turbine slower. 3" crossover is usually used in 2200+ HP apps.

Im running a billet 7675 on a 383 and it spools so quick it is ridiculous, even the shop that put it together was amazed at how fast it spooled. Im getting full boost well before you are probably low 3000, maybe even in the high 2000 range but I haven't really paid that much attention to know exactly.
