This turbo is perfect for 190/100s. I'd be willing to bet it wouldn't clean up 225s.It would do okay I think. Might be a little bit big for that size but it would give you a lot of room to grow in injector size.
I think what everyone needs to realize is this is still a 300 frame charger. This turbo is not a substitute for a 472 or even a 467. If you gate it good with a big injector and spray it hard i think the average 6.0 could see mid 11s. My truck runs mid 12s on fuel all day with 190s and a friends truck runs 12.2s with a 371 and 225s. I'd put this turbo somewhere in between. Jay@php said he went from a 371 to a 369 and egts went up. I think this turbo is a great substitute for a 366 but unfortunately borgwarner made some ridiculous claims (outflows a 472) that it flat out can't back up.What kind of hp are these putting down?
better yet, track times?
