.....:laugh:....."If you build it... They will laugh". I don't know if thats a compliment or an insult!
i see him getting pulled over alot for obstruction of view!
+1 enough said!he probably needs a spotter just to get down the street safely :laugh:
that thing has Hot Wheels written all over it :crazy:
stacking roots blowers is the rat-rod equivalent to sequential turbos. It was never terribly common, but it was by no means rare.
If you have a roots blower with a 2:1 ratio, it will pump twice the air volume than the engine would draw natually aspirated, at any given rpm, two 2:1 blowers therefore move roughtly four times the air; ofcourse a single blower could be run with a smaller pulley to simply spin it faster and raise the ratio, but that maxes out the blower sooner and generates additional heat. This is where the benefit of twin roots blowers lies; twin blower can be spun slower thusly keeping heat down, while the multiplication effect significantly increases air flow. It may not be an ideal set up, the efficiency of turbos proves that, but it it effective none the less.
interesting, i did not know that. so would this be, in theory, the same reason why i saw two vortech blowers on a diablo? or is that not the same because theyre centrifigal blowers?
