Dull Pop Sound Comeing from area of Passenger Side Header
I just completed the entire install of my 9 PSI Powerdyne BD11. For starters the car has been off the road for 5 months with the battery disconected. I started the car up and it idled a little rough for a few min then things started to get smooth out when everything started to warm up. I did a few quick 1/4 thorttle revs to about 2500-3000 RPM in neautral and after the Rpm starts to come down I hear this dull but noticeable POP come from the area of the passenger side header. The car maintains idle after being reved and it dosn't stall out. My fuel pressure is currently set to about 36 PSI accoring to my Autometer Electric F/P gage and Timeing is at roughly 14-15*. Could this pop be from a lean condition or is something wrong internally. The engine is practially brand new, it has about 2000 miles on it since being installed last summer.
Could be your heater core under the dash. Mine did the same thing just ONE big loud pop. Look for antifreeze on the floorboard and near the back of the passenger header coming out of the firewall. just my .02
