With gen 3 rods be careful how fast you bring the power in. What size turbo?

 

78/75.

 

so it comes in quick then, at 20psi on a 6.0 have you ever measured your pre turbine drive pressure? That may answer some questions.

those have a really small hotside IMO.

 

haven't measured, thought about going to a better turbo or slighty bigger. Without being able to compare a different turbo, I did think it kinda started running out of steam at the big end. But I'm getting decent times for my set up.
