Any one going? We should be there, hopefully with an all new Barry Grant 400 fuel pump and fuel system, after the 280 packed in at the nats, we have now been told the 280 is only good for upto 650 hp so no good for our setup, and we may manage to squeeze a bit more out of the car at the top end! Hopefully back to consistent 9 sec passes,

hey mark, i would have thought that a 280 would be ok on your car, what power is your mtr? around 700 horse, i only run a holley black 140, on the tube challenger that goes 8.90s and i worked out that it has 750horse,
might be wrong if i am could mean with a bigger fuel system i could go faster
will be at shakey, shakin that ass

To determine required fuel flow, multiply your total expected horsepower
by a bsfc (brake specific fuel consumption) of 0.65. This will give your
fuel flow requirement in lbs/hr. To convert to gallons per hour, divide
this figure by 5.87.
You should pitch "total expected horsepower" a bit above what you realisticly expect to make from your engine.
For example;
If you are expecting your engine to make about 700hp you might be wise to shoot for 750hp.
So 750 x 0.65 = 487.5lbs/hr
487.5 / 5.87 = 83 gallons per hour.
So you need to select a fuel pump and install fuel lines/filter that will deliver at least that amount.
Hope this helps.
