Dave....we use the 830 allot for circle track applications that are ran on larger 3/8 to 1/2 mile tracks where the RPM of the engine stays above 4000RPM....with high speed turns and low end throttle responce isnt that critical.....

In most street/strip applications either the 750 will be used or the customer will go strait to the 950/1000......Jesse @ BIGS!!
