Shawn has always been a huge advocate of attacking any factory cylinder head with the die grinder, in search of greater head flow and better performance. I also agree with this CFM searching mantra, especially when performance cylinder heads and manifolds do not exist or are otherwise out of reach.<\/p>\n

With common Ford and other head designs it is a simple matter to research the work of previous head porters and mimic those successes, however with the Lada engine, this information has been somewhat less easy to find.<\/p>\n

So how do we know if we are having a positive impact on head flow?<\/p>\n

A cylinder head flowbench is the best place to start; it measures airflow in test conditions, somewhat like a dyno, but for air movement. It is very possible that hand porting efforts can actually harm flow, and make an engine perform worse if done incorrectly, so a flow bench is a great idea.<\/p>\n

One problem,<\/p>\n

They are massively expensive, and for the purpose of our IVAN2104 project, far outside the budget.<\/p>\n

While Shawn twirled the air power die grinder impatiently, \u00a0I stormed the internet in search of a home built solution. I found it, and the whole idea of building a home flow was not expensive or stupid as it sounded. This link from musclecardiy explains the theory, parts, and process to build your own DIY Flowbench.<\/p>\n

We were off to the Home Building Supply store and quickly located everything we would need for the project. The following few hours were spent doing art & crafts in the shop, and at the end, much to our surprise, the contraption worked.<\/p>\n

We did a few basic tests of the bench and found it did respond to valve lift changes and should give us our flow baseline and a means to test as we open up the ports on our Lada 1500cc cylinder head.<\/p>\n

The test data at this time can only be compared against the items tested on this bench, we are attempting to have a calibration plate built so that we can convert our numbers to the more familiar CFM measurements. However we can measure that a port with 9 inches (of water) vacuum reading, after porting drops to 8.1 inches (for example) demonstrates a 10% flow improvement, if a change results in greater vacuum we know that we have harmed flow.<\/p>\n

As we work with this crude but exciting tool we will publish our test data for reference and discussion.<\/p>\n
