Stagger jetting question
So let's get back to my original question. Does anyone do the staggered jetting? I am not going to mod the intake and my engine was a little lean on the dyno. The builder jetted up, but my final pulls were set at 13.2 to 1. I was only considering adding a jet size or 2 up . I understand why Vizard wants the two opposite corners done. My intake is an unmodified open plenum max wedge port M1. There is a 1 inch spacer installed by the builder.
I appreciate the answers and my dizzy is locked at 36. This is race only. I know every combo is different and may respond differently. So let's keep it simple. Anybody running staggered jetting on an open plenum intake?
And thank you all. I wish my thread on leaning out my cruise A/F ratio on my street dual quad tunnel ram Roadrunner got as many replies! That has been a mess. Clearly running on the transition slot and rich. The people at Holley can only offer to sell me new Quick fuel 450s or there new FI tunnel ram set up.....oh well. Thanks again all.
