Dyno Proven Horsepower &
torque |
|
To illustrate the potential of Arao
Performance 32-valve Cylinder Heads, we dyno tested a 5.7L Chevy small
block with 10.0:1 compression, LT-1 cam, single-plane intake and 750 CFM
carburetor. We tested the Arao head against a ported and polished,
well-known brand 2-valve aluminum head with 2.08" intake valves and a
stock open-chamber iron head |

HORSEPOWER
The chart shows the Arao Performance
32-valve heads made 474 HP @ 6000 RPM, 159 more than the high-end 2-valve
aluminum head (Brand X) and 203 more than stock iron! |

TORQUE
The dyno also reveals a broad, flat torque curve with a peak of 437
lb./ft @ 4500 RPM. In fact, 85% of peak torque occurs all the way from
3000-6000 RPM!

|
RPM Range
The unique valve gear arrangement
made possible by Arao Performance's patented head design (US Patent
#5,007,387) allows rev's to over 9000 RPM without use
of exotic valve train parts or freakish valve spring loadings. |
|
FLOW CHARACTERISTICS
The graph shows the intake flow
capability and higher volumetric efficiency of these heads as compared to
a highly developed aftermarket 2-valve and a stock iron unit. The large
flow openings are more beneficial to acoustical or ram tuning, creating
even greater volumetric efficiencies during engine operation. |
