I have now seen two on-line comments about adjustabel fuel pressure on 1.6's. I was under the impression it was a 1.8 only thing.
Two questions then... First, is that modification approved by SCCA for 1.6's? Second, I need to understand how that modification will gain horespower or torque versus the standard adjustmemt of the AFM and timing on the 1.6.
In my case, I can achieve a near ideal air fuel ratio from 3,000 RPM's to 6,800. (But at the pretty immaterial expense of being too rich below 3,000 RPM's.) How can a higer (or lower) fuel pressure be used to affect HP or torque more advantageously than timing and AFM adjustments alone?
Thanks in advance for the tutorial! Rick
