    supercharging a tb42

    just wondering if someone has done this and is it worth it.
    i have a tb42 dual fuel - carby motor.
    the torqe is good but overall power sucks.
    i was thinking of of fitting a sc12 type blower. they can be turned on and off like a air conditioner.
    dose anyone know if they are compatible with lpg?
    any help is appreciated.
    cheers

    I don't know what your looking for but an sc12? It would be to small for a 4.2 I would think. ^ to part 2 of your question YES you can supercharge on LPG with a blow through type your looking at.

    Your TB42 an "E" or an "S" ???

    I have a tb42e on dual fuel with a sc being fitted next week - that said, apparently it is best to lose the LPG completely due to reasons beyond me (like, proper adjustment of fuel mixtures is a lot more difficult, different boost required for each?, etc).

    I'll know more in the next few days as I found out what's going in etc, and let you know.

    how about a solenoid that swaps to petrol when the blower is engaged. how about the sc14 is that any better.

    SC12 was fitted to Toyota 4AGZE 1.6 litre engines, SC14 was fitted to 2 litre Toyota engines. Both are far to small for a 4.2 litre engine.

    If you can wait till tomorrow mate, I'll get the model of the one being installed in mine - all I know at the moment, is he is talking about 60-80 kilowatts extra - talking 180-200 odd kw's for a vehicle that came off the showroom floor with a touch over 120 ...

    Assuming you're looking at second hand blowers an Eaton M90 off a supercharged V6 Commodore (also used on some American Ford V6 engines) would be closer to the right size.
