AFD start up a Cleveland Cylinder Pressure / Valve Timing /
Pump Fuel Testing Program.
Everyday I speak with countless engine builders and customers from all over the world about AFD cylinder heads and their combo's and outcomes and hp and torque curves.

The magazines you read (and I do) can sometimes scare the readers into believing there's a limit to compression ratio's using pump fuel,and it eventually becomes the normal standard line of thinking for young engine builder's or DIY's when the actual truth is a long way from it.

It is all too common that a customer will tell us how much static compression they want to run and then proceed to ask for advise on making maximum all out power for their Pro Streeter or Weekend Warrior.........as a result of the perception out there, I have set up a new engine test program to explore the limits of cylinder pressure (not static compression ratios) on pump fuel engines fitted with AFD cylinder heads.It is widely known that with our chamber design, only 28 degrees of total ignition timing is require for the engine to achieve peak torque on pump fuel.

The question that needs to be anwered is "What kind of cylinder pressure will it take to achieve a detonation point closer to the igniton timing peak??? and what will happen to the power curves??"
The objective of this test is to exploit the relationship between cylinder pressure/valve timing/ ignition timing using 98 pump fuel.
I bet it is a lot higher than anyone thought pump fuel (98) would handle.

I will post the results a soon as the testing is completed.................................................Dave

New High Port Race Cylinder Heads for the Cleveland/Clevor engines.

Development has began on our new High Port Cylinder heads for the Ford Small Block engines,these are high flow,high output cylinder heads.

The intake port design and chamber design have been completed,work continues on the exhaust design.

As soon as the exhaust is completed,tooling production will start.............Dave

Testing of the AFD (High Rise) Prototype Intake Manifold is completed.

AFD has finally completed testing on the prototype intake manifold for our range of cleveland/boss/clevor type cylinder heads.The results were outstanding, torque curves on a variety of engine sizes.
Tooling is now being created for this product to go into full production in a few months time.

Once again..AFD has kept our customers in mind when developing tooling,a higher investment on AFD's part= less production cost= cheaper product for the customer

I will be starting development of a new under the hood single plane manifold very soon for those who just cannot make any room under the hood........ Dave.
