I am looking to put a super charger on my baja 240sport it has a 454 330hp.Iwas going to freshin up the motor over the winter and put forged pistons and a steel crank new bearings etc.Is that the way to go?how much boost can i run safe?

From what ive read the 7.4L has weak internals & a sc may not be most reliable option. i have same engine & saving my nickels for a 502 to replace it.

Upgrade your fuel system and oil cooler .Arp rod bolts , upgrade valves. We ran 5 psi for 3 seasons prior to removing blower to sell the boat easier.
The new owner ran the boat over a pile of rocks first time out!

You are on the right track. You also need to put in inconel exhaust valves.

I did this in my old boat. ran a 174 B&M at 5lbs boost. made 560 hp on the dyno. With the small blower the boat idled like it was stock.

Oh yea, i used my stock fuel system and stock oil cooler. Just be sure to get fuel press and boost gauges to keep an eye on things.

To build a motor with a crank rods heads and blower is going to be 15k. I have a 540 that made 625@5750 for 6k. Only has 22hrs on it. This should rocket a 24 baja over 80.

Sutphen30, are the blowers the polished 172's or the powdercoated black ones? I'm asking because I am looking for one to purchase asap. Port blower ate a piece of the flame arrestor.
