bracket racing a FED
THE FRENCHTOWN FLYER:
Speaking of charging batteries, I would also recommend using an alternator. They absorb little power. One horsepower = 746 watts. At 16 volts that's 46 amps worth of charging, and a fully charged battery will not draw 46 amps worth of power. Even at 50% efficiency that 46 amp draw only requires 2 HP. Trivial.
Remember - consistency over maximum performance?

Noway to get alternator in the mix,if I wa nted one. With smog pump and fuel pum being belt drive there is just no roon left. I have cranked car about dozen times in a day and never had issue. No water pump,only fan is trans cooler,ignition is msd mag and fuel as said belt-driven. Only juice draw would be small fan for trans,computer,delay box and taillight if on.
I do have a new starter on order which should be better since lot newer and probably more efficient. I also have booster pak on four wheeler if cranking became issue.
Not saying alternator is bad idea just next to impossible on this deal.

I'll just have to make sure I have a generator/battery charger that puts out enough amperage to run everything and "top off" the battery.
Speaking of battery, I suppose the only way to go would be with an AGM battery for safety sake.

Moroso has an electric motor with a belt to drive a stock style pump. They work well but its just more stuff that can go wrong.
From the sounds of what you're going to do engine wise you could get away with a standard lead acid battery. Mine worked OK until my 60 foots went under 1.20. An AGM would always be a better choice though.

Thanks. The pump I'm most considering is a "remote" unit from Allstar Performance and it pumps a LOT of water! Price is around $150 (I'm hooked up with a race parts warehouse) and just bought a 1200 Goldwing radiator on Ebay for $35 including shipping to give it a try.

Funny thing about all the reason why you couldn't bracket race a fed 'when I started project. Two funniest. They don't work if so someone would be doing it and winning the big money races. Best of all they are too inconsistent. That old guy in Kansas told me he had one customer call him complaining about new car he built that made 5 runs and last one was .001 off first 4.This was with 526 hemi with 14-71 high helix. Of coarse the guy was joke complaining. Not sure what you call consistent but if it take more than that, you might be asking little too much.LOL
