my pro systems carb worked spot on right out of the box !! love my procharger !

ok,iv been watching this thread,now il chime in,i just finished a pair of 588s,dart 355cnc heads,whipple 8.3L,and a fairly big hyd roller cam,just north of 1200 hp at 6500.i did a pair of 523 inch motors with edelbrock heads,minor blending of bowls,almost identical cams as my 588s,with m4 procharger,it made 1298 hp at 6500,on the same dyno as my 588s.damb near 100 hp more,my 588 were at 12 lbs boost,not sure if i want to go any higher on boost with 92 octane,the m4motors were at 16 lbs boost,and safe at that with 92 octane,will the 588s make more hp at 16 lbs boost,yes,would it be safe on 92 octane,i dont know,and not going to find out,maybe dustin can answer that,i cant.buy the way,both engines are carburated,no fuel injection.is it safe to say the pro charged motor makes more power,yes,if the pro charger was on my 588s,id look for 1400 hp,on 92 octane.now,wich will be more efficiant for most boating,hands down,the whipple engine,pulls like a trane from idle all the way to max rpm,the pro charged engine,dead under 4000 rpm.if these engines were in identical boats,crusing at 3500 rpm,and then both wacked the throttels,the whipple boat will leave the pro charged boat,and that xtra 100 hp wont catch up for a mile,by then,the race is over!

just wondering,did you dyno the engine?

Mike, can you post the dyno sheets on the 2 motors just for comparison,

i have the sheets,but i dont know how to do pictures on here.

If you have them on your computer, in reply, click manage attachments, click browse, find them, click on them, click upload, click submit reply.

That was my thought also. The whipple product is by a boater for boaters and is the best turn key diy kit. Dustin is easy to reach if you need info. Customer service is extremely hard to find in this (or any) industry.

Which blower makes the most HP? They can make equal boost with similar sized blowers, but PC can boost higher on pump gas as they have the biggest intercooler. Thats a bench racing arguement and has nothing to do with being fastest on the water, and turn key all season. PC's huge intercooler is a huge advantage, Whipples around when you need help and has the bugs worked out of his kits. I would choose the one who backs their products.

What was the cost difference between the Whipple and Procharger systems ?

the pro chargers were on the engines that i rebuilt,so i dont know the cost of those,the 8.3L whippels were 7000.each,that does not include carbs,drive snouts, or anything else you need to make them work,i allready had these components.

I am watching the thread also. Thinking about supercharger for 502MPI mag but concern about the Bravo? Don't want huge HP just basic upgrade but don't want to blow up the drives. It will become very costly. So Prochages got set up and running issues but easier on drives than whipples. So not sure what to do. Don't want to change my boat with stronger drives! Any thoughts?
