Your lower is alot more effective than Eric's. Yes with 4 liter whipples & 6 drives it would run 140 MPH.

So Reggie the 6 drive has a thinner gearcase than the -4 SCX because of smaller gears and counter rotating shafts verses the SCX -4 single big gears ?

Yes, it's taking water in through both drives and the one large pickup at the keel. Those 3 go into one large strainer. The intercoolers each have their own pickup and strainer.

Its actually not to bad...I can live with it for sure. We just want to see how it affects the performance/water pressure/oil temps overall. And yes, we are still pulling through the pickups. We may go back to no spacer...it just kinda depends.
