Your system has to be one of the nicest set ups I have seen for a pro charger. Although the gimbals could be the weak link on Lake Michigan. See you this summer.

I'm on my second boat with Prochargers, M-4's 1100+ hp, no problems. I don't know where the story of them being hard on drives came from, my Baja had XZ never blew one. I like the way the power comes on.

Thanks,
Yes, the gimbals are a weak link. Broke one a year back at over 100+ mph,it was not pretty. Drive was only left attached by the tie bar, made for a long day. Schumaker Performance is one of the few engine builders I know that builds a great fuel injected pro charger motor.

I guess i don't understand the ecu part, the vortech comes with a programmed ecu and a map sensor. This replaces the existing ecu correct? If so is it any good?

Thanks

A custom tune is necessary because A/F ratio does change with load and atmospheric differences. All reputable custom builders come tune the ECM's in the boat. I know mine changed from the dyno to the boat quite a bit. I'm sure Vortech runs theres to err of rich for safety. If it turns out rich in your boat you will have a black transom and all the sequelae of unburned fuel. It may be okay.........maybe not it's nice to know that it is right. In the scheme of the cost of the project this will not be pricey.

CNC nice set up..........

I was out there running with you when you broke the gimbal. That certainly was a mess. I have to agree on the Schumaker setup.

Thanks for all the help.

The way of increasing the fuel to the engine with the boost sensitive fuel pressure regulator on the stock ECM is not the right way to do it.QUOTE]

I was out there that day too, way behind you guys! I remember hearing what happened with the broken gimbal ring, Id have definitely needed a new pair of underpants if it was me...

Glad it all worked out though...See you guys this summer...

Summer cannot come soon enough for me.
