70 Double Blown GTO
My 1970 GTO with two blowers. It's 474ci Pontiac engine with a 8-71 blower
on top of a 6-71 blower. This is from the last day of being double blown.
I'm going to one single 8-71 blower and going racing. The front clip was
removed to make it easier to work on. The reason for the double blowers was
not as a power enhancement like many ASSume. I stacked the blowers to have
a car that stood out in the crowd. Most Pro Street cars were starting to
blend together. If you seen one, you had seen them all. That wasn't the
case with this GTO. Al someone had to say was "The double blower GTO" and
people knew which car. I was told it couldn't be done, so I attempted it
and it worked. It stayed that way for almost 2 years. I knew a twin turbo setup would make more HP. I knew I could
have run a 14-71 blower and made more power. That wasn't the point. I
wanted to be different than the other cars in the parking lot, I did that
now it's time to ove on. For all those people who don't understand why,
I'm not going to try and explain it to you anymore. Get over it. I didn't
expect EVERYONE to love it. But you won't forget it.
PONTIAC - stock Pontiac Super Duty 421v8/405hp vs stock Chevy 409v8/409hp on DYNO
WATCH THE VID TO SEE HOW CLOSE THEY Dyno TO THEIR FACTORY
405hp/409hp ratings. Growing up.....Pontiac/Oldsmobile old timers/EXPERTS
who taught me most of what I know, often told me Chevy rated their horsepower in a more
optimistic way than say Oldsmobile or Pontiac. I've even heard Pontiac
rated/tested their engines in a 100 degree room, compared to Chevy in a 60
degree room. These Dyno results seem to reflect
that some of what I heard was true. Both of these engines are great, but
the results do seem to show that Pontiac was not rating their horsepower worrying if it
would cause "songs to be written" about their engines .... like the great
song "She's real fine my 409"--(Chevy).
