I am using the holley carb on my Bridge port 12a, just out of curiosity, What size jets are u guys running on the primary and secondarys?

i cant believe it!
 

Nobody on this site is running holley carb on there rx7? With some useful info...

I have a bridgeport, but not holley powered. Its weber carburated.

I know this is an old thread, but bump. What size jets are you guys running on a 1/2 bridge or full bridged 12a w/ a 600 cfm??

I am currently running 58s in the primaries and 60s in the secondaries, but the car is still running rich

On my bridge i was running 66 jet on holley 600

wow! Great info there ace!^^ Was it a 12a or 13b? Did you happen to dyno it to see what it put down? Was the car running rich or lean? afr??

same 66

66 at all four?? Primaries and secondaries??

12a bridgeport on side housing and midle streetport, 600 holley vac secondaries. on my I only have jets on one side of the carb, car was doing 13.5 1/4 miles 103mph. but never toked to dyno, never run rich sparkplug burn fine

So are you running a 600 DP or a 600 Vaccum secondary carb? Why do you think it's running rich? Because it smokes or because the plugs are black?

Sorry for the late reply, but yes, the plugs are pretty black, full of carbon.... I actually just dynoed the car and w/ a 3rd gear pull it made 151hp and 102 ft/tq. The a/f were 13:1

Doesn't this seem a little low?? BTW, I have NOOO idea where my timing is, prob should get on that ;)
