Your screen name says it all.

I am well aware of how the system works and as you know proper setup for the EFI motor includes having the ecu re-mapped to take it out of the the cold start mode it defaults to after removing the thermostat. Not biased at all here, like I said all the kits are good if set up properly.

Good info guys...Thankyou and keep the info coming, perhaps like Indy did in his post about speed gains after all it is the second half of the equation here.


Strip POker , I think that the price difference is very close at the time I am writing this. I know pro-charger usues a huge intercooler that I know has to help with the air charge temps.

Bryan,
When I got my setup it was after tons of research here on the board and had actually decided on the Whipple( the old kit) but in order to install it in my boat required cutting a hole in the fiberglass section behind the back seat for the pulley which I did not want to do. In the end it all boiled down to price, I found my ProCharger here on the board brand new for only $3500 from a guy who took it in on trade and have been impressed ever since. If I were to do all over again and had to pay the going rate I would probably lean towards the new style Whipple though. Just my .02 cents.

I believe the m3 comes with the bigger innercooler but you have to fabricate a place to mount it , They recommend mounting on the stringer They smaller kits it was a option

Ck out Rtech on what they did with there innercooler its alittle tall but it works, its on top of the motor not hanging off the side with 10 feet of pipe.

When I cked on the Whipple vs the proCharger $$ it was about 2k diff. I know ProCharger gives a discount to dealers in Nov or Dec $500. per kit . That would help if the dealer passed it on to ya.

Good luck shopping

What is your application?

Bryan Rose

This is for a 98-2002 Hp 500 EFI , in a Donzi 27 ZX that runs 70 MPH now.

GPM

I would think you should be able to make 750 reliable hp with either system. I've been running the Procharger for 4 seasons now without a problem.

I'm not biased at all, I own neither and probably never will, beyond any performance arguements I am an old school roots blower fan. It's an astetics thing with me. You are right eithe rone is only as good as the installation, the diffrence is that a proper installation is much simpler with the Votech kits. Tey fix the fuel system the right way and don't leave it up to the customer to figure out wh the hell to do to make it run right throughout the engines RPM range not just at WOT. Prochargers can make great power and can be very reliable there is just alot more guesswork and ultimatley money spent by the customer to make it right. Accessible Technology, prochargers parent company, does not have the best tech support in the world either, you can always get someone on the phone but they don't ussualy have the first clue what they are talking about and wouldn't know what stoitametric ratio means to save their life. If you call Vortech Marine tech support they will give you Bob Endress's personal cell phone number that he will answer day or night and not hang up until you have the problem solved. He will drive or fly to youy home to fix the problem if neccesary, I have had nothing but great dealings with him and I don't know anyone who feels diffrently. Bottom line is that you are going to spend alot more money making a procharger make the same reliable power as a Vortech.
