Anyone know what company makes a super charger kit for indmar 340

[jk13]

The X-80 has two engines

Does anyone know how the drive train works, assuming one prop?

Two props, two transmissions.

No one makes a kit specifically for an Indmar motor, though any GEN-I SBC kit could be made to work.

That said, you are going to want a screw-type blower, not an centrifugal style. You will also need to be able to tune the motor somehow, bigger fuel pump/injectors and I'm not sure how much the bottom end can take on a boating application. Likely some bracket and intercooler fabrication as well. I'd expect a minimum of a $10,000 investment (excluding any internal motor work) if you do 100% of the work yourself, including tuning.

$10k? Seems a bit high to me.

Ahhh, I can see that now. Mahalo.

There was an Xstar for sale up here a few years back, it had a blower on it.

You are looking at 6k for the blower alone.

well I wont be doing anything anytime soon as the season is upon us. I am just gathering info for next winter at this point. So lets say I go with an LSA and its a gen IV motor, who is making adapters to work with my transmission or would I have to replace the transmission as well? Then nothing from my current motor would work so I would be looking at new manifolds as well. So I could just not do the LSA and get the LSX if we are going to that extent. hahahahahahaha its only money right!

Gotta figure out throttle too...

Stillen s/c may be worth looking into.

[Nitrousbird]

Stillen s/c may be worth looking into.

Stillen doesn't make superchargers for domestic motors.

Stillen s/c may be worth looking into.

If they do have one, find out who they're buying it from and save some money on the name plate.

Be sure to note those are not for MPFI.

MA, that link (on the stillen website) says edelbrock...

And that it is them selling an Edelbrock kit. Also, that's an old-school Roots supercharger, not a Screw style that you would want. Edited April 17, 2014 by Nitrousbird

I don't know the newer GM small blocks, but this might be a bit closer. Looks a lot like an Eaton blower to me.

wow. 30 bucks and hour.

Easily. If we roll with a crew of 8-10 and go really heavy... Figure 15+GPH for the bonkers big wave.

[Bawshogg]

Its not the 130k $ boat price that kills ya......... It's the $800 dollar a month fuel bill. Lol.

I use nowhere near that amount of fuel, and usually spend 500-600 a month during the summer months on boat fuel.

The bell housing pattern for the gen I/II and the gen III/IV are the same minus one bolt, they will bolt up, I'm not sure about the distance the crank sticks out the back and how it the flex plate would mate up with the damper plate. I believe it is compatible, people will bolt up early gm auto trans to LS motors. www.ls1tech.com has lots of info. I honestly think if your mechanically inclined, sounds like you are, it wouldn't be all that hard a conversion to make.
