Can we try it on a L-67???lower pressure Why can you explain I try it on a Chevy caprice whit a 5.7 Lt-1, and it'* 0.2 on 1/4 track.We make many test and the car is always faster at 35 or 36 psi....I don't understand but the result is there!!!!

Because the fuel injectors are different, and they may be managed differently. You're already running the lowest fuel pressure of any Bonneville.

The stock regulator on the 94/95 L67'* is only 2.7bar. All other Series 1 cars are 3.0bar. All Series 2'* are 3.5bar.

If you want to run lean under boost and go boom, go right ahead.

There'* something funky about that one. Higher fuel pressure (in general) will give a better spray pattern and better fuel atomization.

There are 2 of us currently running 4.0bar on our adjustable regulators. (3 AFPR'* are currently running on this Forum).

I'm just surprise about the result and I don't understand Why this engine have more hp...I know that I don't want make my 3.8 */c leaner.

Different injectors, different manifold design, etc.

Totally different setup.
