TC 67 vs TC 76 Twin TC-67 ball bearing turbos vs twin TC-76 journal bearing turbos. Which would you choose? I have both of them.
App is my '08 Z06. 427/tfs 245s/tr6060..100% street car/from roll racing.
Reason I'm considering it is I have a C5 with a powerglide I could use the bb 67s on and be legal to race in some classes. It'll be quicker even with a little less power because of the glide.
Edit* I'm not asking which size would be better for which. I guess I should have asked, what are the merits of a dbb turbo over a journal bearing turbo?

What's up brotha!! What size engine is in the C5 again? I'd say that the 427 would be able to spin the 76's just fine without needing BB. What compression is the 427ci?? The most important question of all, when are you coming home?? =)

408 in the C5- 9.5:1 with TFS 245s
427 in the C6 Z0- 9.5:1 with TFS 245s Almost apples to apples in the power production department. I just never read much about dbb turbos. I knew they were able to spool easier, just wondered if they were "better" as far as durability.
Disclaimer- I do not have an engineering degree.
I will be back again in July buddy.

Yes they are. I know this is for garrett turbos but here is some info. http://www.turbobygarrett.com/turbob..._ball_bearings
I dont think you will have a problem with durability with either of those turbos though.
