    Howdy all.

    I am very bored atm and also hungry for some power. So I figure, I've got some money and I want to play around with supercharging my ute. (253 V8).

    So my question to everyone is: what supercharger would suit my application?
    It will be blowing through a holley 390 carby and an edelbrock manifold. Also I want to do it pretty cheaply.

    I have looked at an sc 14 but I cont know if it would be big enough. I think something like a vortech/sta style would be good but I dont know if I can afford something like that. The other option is an eaton M-90.

    Let me know what you think, is one of those three better than another, have I missed an option all together or am I an idiot for even attempting this.

    Cheers,
    Steve.

    No such thing as a cheap supercharged application. There is all the added cost aswell to go along with the blower. Maybe look at upgrading to a 308 if your lookin for a power boost.

    get the bigger engine first, then if you still decide to get a blower you will like the results more. the sc14 is way to small, it struggles in the V6 application at anything over a couple of psi. even if you stick with your current setup you would need to get the holley rebuilt to suit the blow through application. personally i like the vortech style blower, can't see it and they don't know it's there until they are steering at your exhaust pipes in the distance.

    By cheap I mean I am going to do all the fabrication work myself, all I need now is my carby (rebuilt to suit blow through), rising rate fuel reg and S/C.


    I would upgrade to a 308 however the 253 is newly rebuilt and running sweet so I dont really want to get rid of her. I forgot to put up there that I was also thinking of two SC 14's. And yes the holley is getting rebuild. (just dont know by who yet). But looking at it now I think the vortech style might be best for this.

    Cheers,
    Steve.

    A project like this need not be very expensive actually. Been there and done exactly this with a Raptor on a 302 Cleveland with 4 barrell Edelbrock carb in a blow through setup, can do exactly the same with the 253

    The General dumped the ailing 253 cause the efi 202 put out as much horsepower...IMO it's pointless building up the underdog of v8's.

    If you wanna blow some money an EFI 304 stoked to 5.7 L would be a wiser way to go !

    As AirStrike said... There's no cheap Forced induction setup... the motor has to be build to stand up to the boost... you may aswell buy an electric leaf blower off ebay attach it to your Holley and plug it into your cigarette lighter if you want a cheap nasty blown engine...
