And another question before I pull the trigger. I have always been afraid to run a blower. I hear terrible stories and a broken motor could land lock me for a while.

Horsepower aside, 'cause I hear the Whippled 502 has 650 HP while the 575SC has 550 or so, which motor is more turnkey? Which should (in a perfect world) last longer given the same lifestyle?

the 575 was designed to be s/c from the start, not the 502.

You could have 2 or 3 whipple 502's for the same price as 1 - 575

CJ:

A blower set is everything but "turnkey." It needs a lot of work.

The HP575 definitely fits "turnkey."

You may also want to look at the HP525. HP-wise, the 525 comes pretty close to the HP575 (for whatever reason, the 525 puts out 40odd HP more than rated.) It's the more modern engine, and no blower.

I was asking myself the same question a year ago, and made the wrong choice. Penny wise and Pound foolish

What's your experience topgunrcf. I need all the info I can get.

Yeah, out with it TopGun. I am considering adding whipples to my HP500EFI's and want to know the truth................

being that I am fortunate enough to be a rider and dont have to pay for the motors, I would suggest a whipple system. They make a lot of horsepower and torque. The torque curve is basically flat which is hard on drives. When we tested the boat w/500efi whipple system the bravos lasted about 30 to 40 seconds under full power on a 35 fountain ts. The actual motors were never a longevity problem just the drives, now running Imco extreme sc's. You pay a lot of money with the 575's for 550 hp but they do come with a 1 year warranty. The advertised hp rating with 500efi whipple system is somewhere around 740 which is a huge difference over the 575. The sound is pretty incredible under boost on the Whipple system as well.

So what you are telling me is that my Bravo XR's will only last minutes under the strain of 700hp?? Even with conservative use of the throttles?? I am just curious if anyone here has actually installed and run them successfully.

I want to whipple my 502 but i cant find insurance to carry the boat and motor so you might want to check in this also. I have heard a whippled 502 is pretty reliable. But depends on the driver also.
