Thanks bud. Not trying to debate what blower system is best, everyone has their own needs, wants, budgets, etc. All 3 style of compressors work well when used and setup properly. .

Just trying to clarify any confusion about a whipple being in boost all the time, requiring rebuilds every year, etc.

I also read that theblowers and whipple type had to be sent out every year or two for rebuilding.

Just curious were you read that? because that is completely untrue

VetteLT193 Said he never heard of anyone NOT having to rebuild every year with a whipple.....I think he needs to take off the earmuffs and step out of the bubble.

It was on a old thread about 575sci motors. I was looking at a 36 with them at the time.

I did beef up the bottom end, but it lasted 5 years as stock efi500 and 5-6psi before I did. My ECU is custom via the boat and an air fuel meter, the only way I would suggest.

I see just a touch under 90 with a 540 and 7psi, 28' Nordic, 1.36 gears at 5500 and a 28P bravo.

My buddy and I have same boat, he has whipple, I have vortech. There is so much mis-information out there it's crazy. We both come into boost just around 4000 rpm.

If you have a vortech, you don't need to "wait for rpm" to get the boost to "kick in". Just like the Whipple isn't making full boost all the time.

If we we both cobbed the power at 3000 rpm, totally in vacuum, we would both get to the other end of the lake about the same time.

There is no waiting with either one, the power comes on, RIGHT NOW.

This is rarely getting over 4000 rpm on this video. Plenty of power on tap. 540/7psi, 28' Vortech

i have a 38 scarab avs with m4's on 540's and have had nothing but problems with the drives. motors have been great make alot of power, but i keep blowin up drives. imco sc's cant hold the power on this heavy boat. upgrading to SCX with sc lowers. only issue i am having is its running way and i mean way to rich. running 850 quick fuel blow thru carbs and they just arent rite. going to 750 pro system blo thru carbs. whats everybodys thoughts on going back to 1.5 ratio on new drives. guy with a 42 fountain with same motors says it helped his motors a ton with putting all the load back on the drives instead of the motors. he is running 13-15lbs. of boost i am going to stay with 5lbs.boat is fast enough. 107 is fine with me, just want more reliability with the whole package. any feedback would be appreciated! thanks

Save yourself the headache, spend the extra $ and buy Whipples.
They dont rattle, they are WAY more efficient, the intercooler isnt a box on the floor..etc.Not saying Prochargers can't make a lot of power, but its doing it the hard way.
Thats going to be my only post because I know the posts that will follow. If you want more info PM me.
