Ok so now does it being a carb require more fuel flow then a injector set up??

not really but thats not enough pump. I would run an a 1000 if it was mine. starve it for fuel and it wont last very long lol.

Hmmmm, intersting... Guess I will have to look into a bigger pump.. Like I said these pumps are good for 700 hp. At least that is what it says per the site..

Thanks :coolcowboy:

you will also need rear notched floats and rear jet extensions,,under boost the fuel will be pushed to the rear rear float bowl,when this happens the rear jets will get air instead of fuel,the jet extensions keep the jets in the bowl of fuel..

you will need a minimum of 150 gph fuel pump to keep everything wet in the fuel system for a pro charged application, aeromotive a1000 or a sx performance 18201 will put out plenty of fuel for your needs..i would also use a -10 to supply from the fuel tank to the pump then to the regulator then step down from their..

C&S specialties makes a aerosol carb that would work the best for your application..They rock!:drink:

if you decide to use your existing carburetor its best to run a annular type booster,this booster idolises the fuel better under boost,a standard booster will have a chitty throttle response..you will also have to modify the metering blocks were the pv's are,they can only flow so much fuel and the two little holes going to the jets will need to be opened accordingly to the jet size used..First jet the engine fat then lein it out,if your lein on the first run and trust me you will hurt the engine...

Ok thanks.. Like I said the carb is going to be set up by somebody who has done MANY of these, so I am not going to question their ability to do a good carb.. I still am in?? about the size of the fuel pump, line size that you guys are saying needs to be used to achieve/feed 6xx hp.. But am not going to ?? it.. Just seems weird that I am using this pump on a vehicle on STOCK fuel lines 3/8 on 12psi, making well into the 6xx crank HP range, yet need a bigger pump then that to do it on a carbed set up.. Again I am not bringing a argument up, as I did ask the question, truly app the input and info you guys have posted up.. What am I missing though as far as the big fuel lines and huge pump for such little HP??? Thanks again

well then just run and see....we'll watch and listen..

Cars and boats are not the same. Cars go wot for 10 seconds. Boats go wot for 10 minutes.

not to mention a fuel injected set up has no float bowls to run dry........

Great point, I actually did think about this after posting back up.. Also do you think the stock merc canister fuel filter will give me enough flow,my dad has them on his big Chris Craft and it flows 30 gal hour at least on that big thing.
