Hi guys...
I just returned from Iraq and Im in process of tuning my N/A full brideport motor with dual true exhaust to borla muffler and holley 600 double pumper(not RB but it has no choke plate and choke body it was professionally dremmled off.

Couple things, I been contacting holley and Car is running strong but I know I can run better.
Holley setup
primary jets: 62
secondary jets: 64

Power valve 4.5
Primary discharge nozzle: 28
Secondary discharge nozle: 31

Car pulls good in primaries but hesitates around 7,8,9,000 band. I was told to use 60 primaries and 64 secondaries but I wanted second oppinion from the racers. Mixer screws are out about 2 turns plus or minus 1/2 turn.running oil metering pump.

Thanks for assistance.

 

Papo,

en que parte de Tx vives? creo que necesitas mas gasolina en ese motor, injecciones mas grandes. el motor se esta quedando seco.

 

I suggest a wideband. SO u can stop guessing what jets you need.


SUggested n/a AF's are 13.0 - 13.6 afrs WOT

 

Vivo killeen, tx, pues trate de subirle los jets y el carro no sube los rpms y entre mas bajo sube hasta 8000 rpm. Pues tengo un spacer de bajo el carb y pienso sacarlo, tambien estoy pensando block metering pump y correr mescla.

 

Las linias de el metering pump se las metes in las dos primeras bocas de tu carb.

JUst push the metering pump hoses into directly into your carb about an inch and zip tie. or they might just hold themselves.. I seen bunch of puerto rican do this
