What Makes AFR Special
|
|
While Airflow Research has
a great history of success in racing, it has been their ability to bring
sophisticated porting technology to their wide assortment of cylinder
heads that makes them truly special. Airflow Research pioneered the tooling
and machinery necessary for true 5-axis CNC port machining, which allows
total flow consistency from head to head once the optimal port design
has been established. No other manufacturer incorporates this complete
machining technology into their cylinder heads.

Research & Development
|
|
Cylinder head technology starts with research. That includes hundreds
of hours designing and hand porting intake and exhaust ports to experiment
and compare flow and horsepower characteristics. Airflow Research has
tested thousands of cylinder heads over the years, for every application
from top fuel dragsters to Saturday night street rods. Understanding the
application and performance requirements is where AFR starts its design
criteria.

Dyno & Flow Testing
|
|
To accurately evaluate port designs, AFR spends thousands of hours on
engine dynos and flow rates are all compared to determine the optimal
port design for specific applications. Testing does not stop in the lab though;
AFR has spent more than their
share of time at drag strips and circle tracks to carefully measure performance
results.

Special Manufacturing
|
| Air Flow Research uses the latest in metrology
technology to bring you the finest cylinder heads available today. During
the manufacturing process, cylinder head castings are mounted in the machining
centers and then searched for and located using optical work coordinate
probing systems. This insures the most accurate location possible to begin
the machining process. This eliminates the "stacked tolerance/human
error" from the equation when loading and unloading cylinder heads
at each work station. |

Quality Control
|
|
Airflow Research's racing roots have set the standard for quality.
Because our first heads found themselves on the fastest cars in NHRA and
NASCAR, we established benchmark quality control standards that put AFR cylinder
heads in a category by themselves. Every aspect of the manufacturing process
- from our in-house casting to final port finishing - is upheld
to the highest quality standards. When you get AFR cylinder heads, you get the
best.

Competition Proven
|
|
| Airflow Research consistently out-flows and out-powers
the competition! And that's not just us talking - check out our
website and read what the magazines have to say about AFR heads. Our flow
rates surpass the competition - not just at maximum lift but especially
at the critical .400"-.600" valve lift curve where so much of
valve time is spent. What that means is more power from your engine at the
track or on the streets. That's AFR power! |
