I've had this DWR pump in my engine now for 20 years. 
No issues. 
I echo Bob's comments.

We recommend the high capacity for all road engines using a standard type crank up to 6000 rpm and the standard pump for race engines, steel cranks or anything over 6000 rpm. Both are precision machined and assembled in-house to control the highest quality.
