    Has anyone installed a mini-Blower on their SBC? I have been told that it might improve my 13mpg gas mileage? Any comments??

    its not a full blown blower stickin through the hood and all.....(read the rest with a grain of salt cause it makes sense to me in an exhausted state) and better fuel atomization may cause higher mileage, as well as increased power from a standstill, resulting in less throttle application being deemed necesary, hence less fuel being dumped into the engine.

    I think he means somehting like a Weiand 144 or 172. They are often called "street" blowers. I want to build a motor with one sometime.

    If you find more information about this mini-blower, I would love to know more. Good luck.

    Most blower setups will set you back at least $1,500. The Vortec types run more in the $2,500-3,000 range. That will buy a LOT of gas! Blowers also increase cylinder pressures and temps, so you have to run premium fuel to prevent detonation. (You'll need a pretty hefty mileage increase to justify the difference in fuel cost alone). You'll enjoy the kick in the seat of your pants from the boost so much that your mileage will drop anyway. /forums/images/graemlins/wink.gif

    So it isn't worth it as an effort to increase fuel mileage, but it'll make your truck a LOT more fun to drive! /forums/images/graemlins/thumb.gif

    definetally not something I would do to increase mileage. Definetally something I will do someday to increase the fun factor of the loud pedal /forums/images/graemlins/smile.gif

    I have one on a 454. I'll just say this, regardless of ANY advertising you might read, blower and fuel economy do not belong in the same paragraph! I imagine some company has found one lone application, where under exact circumstances (something like going straight, downhill, 15% throttle) they may have achieved some ridiculously slight increase in gas mileage (say 2%). But as soon as you take that same test vehicle and put it in real life driving, I'm sure the mileage drops dramatically.

    Just my 2 cents worth, and that's all I have left after filling the tank on my blown truck!

    yeah I forgot, blower means bigger carb, bigger carb means more fuel, more fuel means less mileage.

    Perhaps it's an oversimplification, but cramming more "air" into and engine doesn't produce more power....it's the extra fuel that does that.....


    Forced induction = more fuel in cylinder = more power = less fuel left in the gas tank. /forums/images/graemlins/grin.gif

    In all the ATI prochargers I have installed, they have gotten better gas milage. Of course the are intercooled so that helps. I installed one on a 89 suburban 1/2 ton 4x4 with a TBI 383, and he gets 16 mpg. It has a 4" lift, 33s and 3.73 gears. I depends on the supercharger, how you use it, and if you have FI.

    yeah and that burban doesn't make as much horsepower as an old carburated 383 with a mini blower would I am sure. Its horsepower relevant, if you can produce 450horsepower with 15mpg PLEASE let me in on this buildup.

    I think the mileage determiner is in your right foot.... /forums/images/graemlins/eek.gif /forums/images/graemlins/thumb.gif
