I have been running some 598's with Blower Shop 14-71's. I lost a motor in KW and now it is time to rebuild, so why not try to make some more HP. I have been researching the quad-rotors and like what I have been hearing.Just wonding if anyone here has any experiences with this set up.

quad rotor EFI on a 540...built by Gt Performance. does the trick for me. awesome power, behaves at idle, turn key...

I have a quad rotor EFI on a 565...built by Pfaff 40 hours and runs great. 1021hp at 8# pump gas and 1365hp at 18# race gas but only on the dyno.

What kind of torque are they making?

What type of heads and cam are you guys running also how many RPM's.I have Brodix 2X, which I am considering selling and getting some CNC heads if it will make any difference. Right now I'm solid roller with 1030hp and 1000tq turning 6400.

I'm running Dart pro 1 heads (non CNC) with a crane roller cam. at 1021hp 985# @6200 rpm and at 1365Hp 1165#

BTW I'm running the 3.3 Quad

Whippled is that a solid or hyd. roller.

Hyd. roller, if you go with a solid you can go higher on the RPM

Still working on that. I will probably take it back to my previous engine builder. Either way I will have both motors gone through. With a probable head upgrade and cam change.

Whippled do you have any trouble getting those r's out of hyd.I like the idea of less maintaince, but I was afraid I couldn't make that much hp or turn the rmp's.
