Wipple vs ATI procharger...Is one any better than the other

I ProCharged and I,m very happy with other modifications a 20 MPH gain 454 Mag.
Better?

Well, that is a good question..both are "good"..but there are major differences..The Screw type Whipple supercharger is the best "roots" supercharger,IMO..A roots SC will make more power than a Cent S at lower RPM's. A roots SC is also always self lubricating..A Cent S may or may not be, which means you would have to tap into your oil pan & bring an oil line to it. They both have their ups and downs, I like the look of the roots type better... Also, consider that all the major car manufacturers use the roots or screw type blower..but the Cent type seems to be the most common in the aftermarket world. Just do your research & make sure your engine can handle it...you can google roots vs centrifugal & learn more.

The PC will be easier on your outdrive. You're going to get a lot of opinions but i'm happy with mine. The good thing about a PC is the remote intercooler. If you frag a blower it will catch the debris. I'm not sure about the whipple. With a little "extra work" you could be running mid 80's.

Centrifugal systems can be packaged around the engine in a number of ways. Procharger uses a remote intercooler connected with hoses; we like to integrate the intercooler into the intake manifold. Either method allows for a much bigger intercooler than is possible with a positive displacement blower mounted on the intake. This is important because it keeps you farther away from detonation, a supercharged engine's greatest enemy.

Packaging is important when selling to boat builders. This is an Rtech system on Konrad's new 800SCi engine/ACE drive package. Same height as a 525EFI, same length as a V-10.

I like the way the roots or Whipple system looks on an engine, but there is something to be said about those "hair dryer" set-ups like the ATI, Vortec, Procharger systems.

BTW, there's a pretty interesting induction system that Dave Wesseldyk (WESCO) personally created for the M5 Procharger he's using.

I know with a wipple there is a ECU flash required, and with the procharger there isnt and ATI's claim is that their system doesn't produce the heat a wipple system does causing the detonation promblem. But my concern with the procharger if there isnt any ecu flash and there only upgrade the the fuel systm is an extra or bigger fuel pump then how lean will that run.

How long have you had yours? Looks great!!!!!

With the procharger system, they supply a boost sensitive fuel pressure regulator. The regulator increases fuel pressure according to boost. More pressure=more fuel during an injector pulse. This was the part of the system that I always questioned. But it worked well for me.

Either "set up properly" will work very well. I had an
M-1 Procharger (for sale) and was very happy with it until I went bizerk and bought a Quad Rotor Whipple!!!

The Procharger is a great unit, again with everything set up properly. A reprogrammed ECU is a must for either if you are doing it right. There is no way a stock ECU program can properly compensate for boost.

whats good for carb motors a 509 with a nick 1050 making a base with 9.5 to 1 670hp or bg 850 less power. PG OR WHIPPLE OR VORTEC? AND HOW MUCH BOOST AND HP CAN YOU GET.

Can you guys do a ECU flash at your shop Im going with 1.8 Rollers a set of imco powerflows and either a PC or wipple charger? Thanks for all of your help

I've had it four seasons and Miller88 had it before me. I did upgrade the upper gears to the newer design. You definitely need to flash the computer because it will run lean top end. Fuel system upgrade is a must also. Blowers get a bad name when people half ass install them. This board is invaluable when doing things your not sure about. Good luck.

You can pop wheelies!~

Airtime: Talk to Dean Nickerson; he makes 1000 HP with our setup using one of his blowthrough carbs and 10 psi. Another customer made the same HP using EFI and 10 psi. They were both at 8.25:1 CR. Your compression ratio is too high for that much boost. We have put 3-4 psi on top of that much CR but it's an expensive way to make a little HP. What heads and cam are you using?

Blowers, Superchargers, MONEY
 

I've been through one of the exhilerating and expensive boating seasons in 2006 that I can imagine. I started with a Crockett 565 Whipple, 930 HP, 1000Lb torque at 3700 rpm. This was in my Lavey Craft 27 Cat. It was awesome. Three drives later it was just as awesome but I was infinitely poorer (1 IMCO that lasted 2 1/2 hours and 2 Max Machine that lasted 10 times longer). HP and torque cost lost of money. Not just in the initial cost for he engine but in drives. Please keep this in mind. There is no drive other than a 6 that will give even the most careful driver all the trouble free hours that we would like.

I know this drive issue has been beaten to death on this forum, but the fact remains, SPEED COSTS LOTS OF MONEY. HOW FAST AND HOW LONG DO YOU WANT TO GO"

I keep telling you guys; centrifugal blowers are easier on drives. Just look at the graph above ~ 750 ft-lbs @ 3700 instead of 1000 ft-lbs. It makes a difference. Don't forget the Konrad drive in this power and price range. It will save you in the long run.

I agree the centrifugal blowers are easier on the drives but for the very reason I do not like them, they have no power at lower RPM. I like my old school roots 16:71.

Whipple and a Konrad...:evilb:

Oh yea and a 28 Pantera!!!

What are you saying Brad, 750 ft-lbs @ 3700 isn't enough for you? Like to zing the rev limiters when getting on plane?:evilb:

Hey Pantera: If you can't break it I'll never have to worry.:D

I like the punch of the roots blower. I had a Vortech V4 540ci engine and hated it. No power under 4000 rpm. I do not enjoy waiting for an engine to boost up. In my application 4000 is 100 mph. I would fall asleep waiting for the boost. KE was having problems with the 1700 engine with the centrifugal setup. Real dog down low. But the latest is they seem to have found more power on the low end by using a new type supercharger. Dual stage? Not sure what they did but my friend who has them was really upset with the first version and now seems to be happy with the more broad power band after KE reworked them.

Hi Brad:

Sorry to hear about your experience with the Vortech V-4. It's a good entry level 700 HP system. All I can say is that when we convert the Vortech EFI system to our intercooler arrangement we see 800 HP on the dyno and no complaints about low RPM performance. This comment is based on our experience with engines using stock heads and cams, with vees operating up to 100 mph, and with cats up to 125 mph.

The trouble seems to start when you move above 1000 HP. We're used to the big intake ports and big cams that work with Roots blowers and we expect them to work with centrifugals and/or turbos. Matching the right compressor size to the job is also important. Mr. Eickert, Mr. Hofstetter and others are blazing trails here and kudos to them all. With help from Mr. D'Annibale we are doing some blazing too.

With the advent of 150+ mph poker run boats, the difficulty of running a one gear boat at low RPM is compounded. Yes, positive displacement blowers can manage this situation, but centrifugals and turbos can make more power, so don't be surprised if 2-speed transmissions start showing up. The advantages in dock manners, idling speed and ultimate top speed make it worth the effort to solve the problem that way.

Love your choice of boats and have no problems with your choice of blower. Maybe see you in Sarasota.

HI there the merlin vr marine 310,cam isky I thing it was 622 617 254,244 114 some thing like that :rolleyes: I had talked to them isky and gave it to nickerson when they built the 1050 this fall. I thought about giving the heads to jim v or nickerson to port them. this winter but money is to tight now.

Kenny, did you call flight control at BNA for clearance before you did that?

The take off was fun...... The landing was hell! Did you splash last weekend?

Im running the stock cam and heads as of now.I appreciate everyone's help on this cause the first time something blows up my wife will never let up.I can hear it now "it ran fine until you worked on it".

No, I put my shortie lowers on Friday night. When I finished, I was give out and I kept thinking something doesn't look right??? I was missing the cavitation plates that bolt to the uppers. So, I have a set on the way......but I didn't figure I could get out of the hole without them....Smith's old 388 lost both of them one day up at the hill and we could not get it on plane!
