Just a note on the 6776 ball bearing turbo

Agree.



Great let us know. It would be nice to have some track 411.

Data logs are the most important for comparison. Unfortunately i do not have data logs for the old passes from 5 years ago with the journal 6776 he ran. Not a totally fair comparison since he will be using a much more efficient 9.5" PTC converter. Ill take note of the charge air temps and possibly the exhaust backpressure numbers under power and others can do the same instead of bullshi tting and bench racing. I can assure one thing.. It will have lower backpressure with the s-trim wheel especially at 5500+ rpm. My guess is 5mph improvement over the 6776/AC converter combo at the same boost levels. He ran with a stock MAFS with a screen in it for his old passes. He will likely have that for a while on this combo too.
