That's a standard thing to do - very few people bother with the more 
vulnerable deep sump, which was really intended for long distance events. We 
don't need them for sprint racing (1/2 hour sort of events), or slaloms.

If you are in a long high speed corner, you can seriously starve the 
bearings. You won't hurt the pump.  Having a baffle will lessen the amount of 
work an Accucump needs to do. In racing we use both.

Do NOT remove the cooler. You will come to grief. Don't believe me? Be my 
guest - its your money.
But I don't understand why you would WANT to remove the cooler. There are 
other places for the Accusump. You are just manufacturing problems for 

My advice? Just put a baffle in the sump - you will be better off for 
spirited street driving and slalom. If you aren't going to race it, don't 
waste the money on an Accusump.
