Hi.
Just running the motor up (part throttle) after fitting a V300 and there's a variance of 200 degrees between hottest and coldest on the EGT's.
IF this the case on full power runs, is it worth chasing the jetting to equalize them ? Anyone have any experience ? Did you pick up HP staggering the jetting ? How much does changing one jet effect its neighboring cylinders ?
580 wedge, heavily ported 572-13 heads, Indy T/R and 2x1150 T/R Dominators.
A little bit more info: square jetted (98?) 1:1 throttle linkage.
TIA.
BEFORE the days of one O2 per pipe per cylinder. I used to dyno for a pro NASCAR team. YOU CAN tune an engine WELL with cylinder egt data. YES it is worth power and worth to understand HOW to adjust and WHY it needs it. Probably most intakes including 2x4 tunnel rams can respond to either modifications AND/or jetting changes. We used to balance all 8 egt's within around 10 degrees F and it ALWAYS was worth power. Based on my O2 data, which was bank to bank only, my right bank was about .5 point LEANER than the left on my INDY T/R with 2 4150's
