Having problems with my 4-shooter! Have
a mild 454 with 32 nozzels /78 return pill.
Have had several people say that it is wrong,
said to contact you. My engine spec are 30/
over @ 12.50/1 compression, ovel port heads/steel/solid
lift cam. Thanks for any info!

You do not really say what the
problem is. What is wrong? Does the car go down
the track ok? Etc, etc.
If you are questioning the nozzle
and main jet choices, then the only way I can
be close to right is to flow the system. (Best
way.) Anything else will be an educated, thumb
nail engineered, wild a-- guess.
Here is the trick question. Do
you know what the actual free flow of your pump
is at 8000 engine rpm (4000 pump speed) or any
other given rpm? All pumps, jets, and nozzles
flow differently, but if I know the pump flow
I can at least give you an idea whether you
are in a ballpark tunable range.
Feel free to resubmit the question
to
fuel@dragracingonline.com and get into a
little more detail.
Have a safe race,
Dave Koehler
