I use twin 67's and it spools quick. I get between 618 and 976 rwhp depending on the boost setting.

single Gt4276 with 1.12 ar hear. Its a journal bearing turbo. It shoudl spool decent, and should be able to make great power down the road. Twins cost more, you need 2 wastegates, and they take up more room. And a properly sized single will just about always make more power. Meaning, if you have x amount of dollars, and you get the biggest single you can for the price, or 2 twins for the same price, the single can make more power.

Good luck, Chris

TC76 is still the best choice for both. Spools very quick and plenty of power for 9 sec passes 140+

how much power on the dyno did it make and what 60' on the run? was is only done once or repeate. im not trying to dispute your times, just learn a bit more, was it a traditional truck manifold kit?

Twin 67s and a single 76 arent even in the same catagory you would need like a 88 to be comparable to twin 67s. Or you would need one of the big turbos forced inductions makes like the s85 or something like that. Those two setups arent even comparable to each other.

Forget BB, go journal. For twins, check out the MPT70 units. However for your power goals, a single unit would be more simple.

well finally decided what to do, my turbo fabricator/mechanic recommended twin 61s that are dual ball bearing, and trust me I am not spending extra let me get that across as people on here and everywhere think I will be spending more but I am not, I am getting more than a good deal and I think this guy is from the mafia at these prices haha. Hope to see what it does on the dyno!

some guy has a forged 370 with twin 61's and it absolutly kicks ***. Theres a video of it walking, or more... running away from a 800+ rwhp cobra. I think he makes like 100 plus more h/p now then that video (1,050 hp i think???). Maybe heel come on there and say something about it.
