A properly designed combustion chamber will allow you to run
extreme compression ratios on pump gas. Our engineers have over
20 years of experience building successful racing engines. We
apply innovative and proven techniques to improve flow in your
specific application, increasing power and efficiency without
sacrificing reliability.We offer cylinder porting services
for any modern four or five valve head designs, any modern motorcycle,
and some two valve heads. Some of the techniques we use are
detailed below.
We also redesign combustion chambers by welding and reshaping
them. This example is a Datsun L6 E88 head. This engine has
10.6:1 compression ratio and runs on 89 octane pump gas! No
gadgetry or trickery, just a properly designed combustion chamber.

*Note1: All
Cylinder Head Porting is custom tailored to the individual customer
needs.
*Note2:
Porting for Turbocharged and Supercharged applications have
more significant modifications performed on the combustion chamber
and exhaust ports, while less work is done on the intake ports
so as to properly balance flow.
