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

Great minds must run together. I'll await Dave's answer to yours.
