What about windage induced by the oil squiters?
Or is enough durability gained to offset windage losses?
I used to add windage trays to my sbc's religously to get the free hp.

If your pistons are really made of raisins as you stated above, you really need the squirterers. How often do you need to refill them?

On a more serious note, you probably will need a higher volume oil pump than stock, like a Melling. Send Jason Harding at Katech an e-mail and see what galley modifications need to be done and what pump they recommend. Some of the heavy breathing Corvette LS3s have had the squirter mod done.

I think I remember reading about these first in the Soltice Turbo motor... before the LS9. Not sure if thats right but it sure does sound like it might be a good option if scratch building a motor... squirters aren't too bad in price from Katech... just wonder what the machine work cost is. "Cool" stuff

$400 for a set of squirters
$159 for block machining

The LS7 pump is a for a dry sump setup, as is the LS9. Have you guys tested the on the regular crank driven style pumps (LS6, melling HV, etc.)? Switching to a dry sump to run these would be a PITA IMO.
Besides you only need one for cyliner #7.

LS7 and LS9 are gerotor pumps driven off the front of the crank just like every other LS engine. We have not tested the piston squirters with any wet sump oil pumps.
