Aeromotive is too much $$ and too loud. Plus on high horsepower big boost apps they are only good to around 700HP, I don't care what their specs say they are not true. A Single Walbro GSL-392 just about outflows it for 5 Times less money. Run two Walbro's and the Aeromotive does not stand a chance and you get to keep $300.00 in your pocket when you are done.
