I was just wondering what the difference would be between going with a 62 or 68-1 instead of a 60-1? I'm really looking for spool up differences and max HP differences. Thanks.

 

Turbonetics says the 62-1 is 10% more efficient than a 60-1. I have heard that the 62-1 is not much of an improvement over the 60-1 and definitely not worth the big price increase over the 60-1. The 68-1 is good for over 600hp on a rotary. I have a 67-1, the father to the 68-1, and there are many people trying to steal it from me. This in my opinion is one of the better all around rotary turbos.

 

But you think a 62-1 can give me even 10hp extra at the same boost level? Is there any difference in spool up time?
