The SuperFlow original, industry standard SF-110 comes with complete instructions on how to measure flow changes as small as 1%. All necessary air-blowers,  controls and airflow measuring equipment are built in. Just plug it in, turn it on and test. The SF-120 model gets a high-pressure motoron the intake side of the SF-110, which produces roughly 30% more intake fl ow capacity. For example, heads tested at 10" with an SF-110 can be tested at 15" with an SF-120. Talk to K&L Supply and choose the model that best fits your operation.
