That is why we have invested so much valuable time and money into developing this system to guarantee you (our customer) that you receive exactly what you are expecting.the best cylinder head money can buy! Yes, it adds time to the developmental process but it is the only CORRECT way a cylinder head port can be developed, reproduced, and be released to market with confidence. These items are the only way you can repeat accurate flow figures for your product. At the beginning of a new project and after the final flow test is complete on a finished product, we check the calibration or our Saenz 680 to verify and insure that what we claim is what you get! We constantly check our bench's calibration with sharp edge orifice plates. Developed to flow 680 cfm 28" it has proven itself a very repeatable machine. Our Saenz Digital 680 is used for flow and high air speed testing.

CALIBRATION: Flow bench calibration is the last (but certainly not least) of the necessary steps to retrieve accurate flow numbers from a developed cylinder head port. There is no quicker way to achieve skewed numbers on the bench than to not have the valve open to the proper lift.Į. It enables you to guarantee that when you are recording measurements for.500" of lift that it is truly. VALVE OPENING FIXTURES: This insures that every time you flow test a cylinder head that you are opening the valve properly. If the clay around the port takes on a different shape then flow numbers are skewed! Our radius plates are doweled and bolted to repeat every time, no question!ĭ. Most companies utilize clay and mold (by hand) the clay around the port to create a radius entrance. Radius plates make the air entering into the intake port a constant. 1/2" radius is typically used so you can change port size and still have a radius plate with the same radius. We custom machine all of our radius entrance plates in house to match our various intake port openings. RADIUS ENTRANCE PLATES: Machined radius entrance plates are a necessity if you want to be able to repeat your work. The only way to do this is to invest in several different removable bore sleeves.Ĭ. VARIOUS BORE SLEEVES: You must be able to flow test your designs on various bore sizes to see the effects valve shrouding will have on your design. 010" change and not from the head being shifted. 010" is removed from the short turn you want to know the increase or decrease in numbers is from the. The only way to do this is with a fixture that locates off the cylinder head dowels. DOWELED HEAD FIXTURE: One word: REPEATABILITY! The only way you can expect to achieve accurate results when developing a port is to make sure that the cylinder head is located on the flow bench the same each and every time it goes on. There are many things to consider achieving accurate & consistent numbers that will repeat anywhere, anytime!Ī. This allows our marketing to boast true and accurate numbers that anyone can repeat after the cylinder heads have left our shop. Consistency is the key ingredient to properly flow testing cylinder heads and being able to repeat accurate numbers. We have come up with a unique solution to this ever growing problem and have founded the benchmark for all others to measure their cylinder heads by. Instead of high flow numbers all you get are excuses! The ever growing marketing ploy of inflating own numbers just to make the sale only to realize once the heads arrive the flow figures on your bench don't match the manufactures numbers. Most of you reading this (if involved in this industry for any amount of time) have probably fell victim to this. Cylinder head porting & flow figures are one of the worst when it comes to this phenomenon. The automotive aftermarket racing industry has a reputation of inflating the truth, coming up with "Big Fish" stories if you will. Let me begin this section with a bit of information and background on this industry.
