1970 Pontiac GTO Double Blower - Blown Pro Street

The 8-71 is on top of the 6-71. The 6-71 is 1:1 and the 8-71 is 9% underdriven so that it moves the same amount of air as the 6-71 does at 1:1. Both blowers move 411ci of air per revolution. The car runs on pump gas. Static compression is 7.7:1

hey ponitiac462... You sure you mean its a 871 on a 671? personally I would have thought it would be other way around. what sort of drive you runnin to each blower? pump fuel or methanol?

Most of the weight is in front, controlling it should be a bitch, not to mention that he probably can't see that well and the engine might fall on him if he didn't build it really well.

o Boże ale bestia !!!!!

but seriously.... what the F**k

lol if he touches the gas too much he will go soo fast hed end up in another universe.

I am curious to know how much boost its running. Does it work in a "master-slave" config, or is one just really really under-driven? And is it a trailer queen? How the HELL can you see whats down the road? lol? Sick car man.

id be more of scared to drive that thing when im thinking my blower(s) might fly off!!

Damn that baby is hunting hard ! nice car

When one supercharger will just not do, why not go with two! Or, maybe they were just on sale that day, he had a coupon...extra bolts...Summit shipped two by mistake...why not!? Seriously: the car is artwork and absolutely perfect!

Around 1,600HP, he says in another video of it.

How much horsepower can that thing do? seriously

holy crap grows a few chest hairs

Killer 8)

Congrats on owning such a beautiful car. How did you come to own it?

That is how it idles without me touching the gas. Once I give it gas, the engine smoothes out and runs fine.
