Jetting 6pk carbs - 12/25/09 01:31 AM
What is the limit on jet size on the center carb and also meter plates on the outboards for vacuum secondaries? They can only flow so much right?
Quote:
Outboard jet plates will allow you to better tune for wide-open throttle without compromising the idle and cruising circuits of the center carb.
Quote:Mopar recommends enlarging the bottom fuel hole in the stock plates to around .084 for drag racing with open headers on the outboard carbs I have one set of carbs like that, they run good also
[Thanks for the replies. I bought a nos direct connection rejet plate kit for my carbs the part number was P3690793 and installed it already. It really woke the engine up. The stock plate hole size is like .030 ? These were .053 You could see the size difference. Night and day in the performance of my engine.
I am interested in the promax plates, so I am still wondering flow wise what size jets would be too much for the size of the air horn. I don't have the right terminology but I guess it like saying if you run a 650 and jet it too much, then you are better off with an 850 for flow rates.
