Rich Krause what are you running for fuel pump,pumps.And fuel lines.

 

I'm pretty sure he's running a bosch 255lph intank, with a kenny bell Boost-a-pump. stock lines. He's also using the carol superfueler. I think he was considering upgrading to the racetronix dual intank setup for this year.

eh, here you go: http://www.kennedysdynotune.com/fbody.htm

 

TimbrSS had it right. I haven't decided whether to try my current Bosch intank+BaP with the new setup or upgrade. If I upgrade, I am leaning toward an external system with a single big-*** pump, larger feed line and using the stock feed line as a return line. But what I have now supports 733+ rwhp, and it was pretty cheap and easy compared to a lot of what I see others doing.

Where is the best place to buy a boost-a-pump.Rich thanks for your reply. your past post have been a big help to me on my car.

 

My friend Bob Kennedy sells them, and unlike many other vendors is willing (and able) to actually answer technical questions! Call 716-693-5354 and ask for him. Prices on some items (the BaP will be as low as anyone though) are a few bucks more than some other places, but like I said, if you call you will actually speak to someone who knows something. You can mention my name if you want. Or look at www.kennedysdynotune.com

The Racetronix harness allows for the Plug & Play addition of any pump enhancer without having to splice into your factory wiring. Even better yet is takes power directly from your alternator with a dedicated circuit to further enhance your pump's output even without a B-A-P.

The single in-tank system supports apx. 550RWHP w/o the B-A-P.

Not to butt in on your thread, but Rich, how much HP potential do you think the boost-a-pump adds?

I am considering fuel upgrades for n2o and am wondering if perhaps it with my stock fuel pump would work for an eventual 200-300 shot on my stock engine (yes I know that's another story).

Thanks for any thoughts.

 

As far as the pump itself goes, I believe that the output is proportional to voltage. If I recall right, I measured 17v at the pump with the BaP turned up to max. An ~40% increase. So, if the initial pump would support 500hp at 12v, it would flow enough to support 700hp at 17v, assuming nothing else became a limitation (lines, fuel rails, and (of course) the injectors, etc.).

It's too bad voltage vs. flow vs. pressure curves aren't readily available with these pumps. Trial and error can be expensive and frustrating. That's one reason why I may go to an external pump system this year. A lot easier to change pump if I need to!

Rich,

You would be lucky to have enough flow to support much over 550RWHP with a factory pump running at 17V. The pumps output does not increase linearly with voltage and at a certain point starts to cavitate instead of producing more volume.

As far as your setup goes you might want to consider a dual in-tank system which is capable of supporting well in excess of 800RWHP with upgraded lines. The entire system is plug and play, reliable and quiet. You would have to spend more than the price of the DP system on a single external pump to net the same volume. You would never have the same hour life / reliability though.

Jack, I think Rich was referring to his Bosch 255lph pump offering 500hp stock, not a stock pump.

I probably confused him with my question. I'm the one that has a stock pump. You think it might support about 550rwhp with a BaP. That is probably right on the edge of what I'd be pushing with 200-300 shot on a stock engine. Interesting. Like I've said in another post... experimentation to hasten my rebuild.

Only gerotor pumps such as the Walbro exhibit a fairly linear increase in output volume vs. supply voltage as they are of a positive displacement design. The factory pump and Bosch pumps are vane type pumps which exhibit more frictional loss as they are spun faster or pressure demands increase (similar to a torque converter in some respects).

You can try a BAP with your factory pump and keep an eye on the fuel pressure as you step up the jet sizes.

This off the tread but it is my tread.Rich I called bob about the boost-a-pump.I got off on EMU.and ask about FAST.bob recommended Electromotive.Are you using it on your new combo.

 

I am using a stock computer with two major add-ons: the Superfueler and the LJ's low-Z injector driver. If I were to go with an aftermarket ECU, I would choose Electromotive over the FAST, for sure. I can elaborate as to the "why" if you like.

Jack: I looked on your website for the twin in-tank setup and didn't see it. Is the best way to find out more to call you?

Rich Krause

 

Rich: My emails were returned by Racetronix within almost 30min every time..and I sent a bunch!

Too bad the Electromotive is not SEFI like the FAST or DFI Gen VII...

The dual in-tank pump system is not listed on the Racetronix web page as it is a custom item generally sold through dealers such as Agostino Racing Engines to support high HP in-house projects / customers. If we were to advertise these units for sale on our page we would not be able to meet the demand for them as they are very labor intensive to manufacture and we have limited free production time here. If you require more detailed information on these units please email sales@racetronix.com or call ARE. ARE's phone number is listed on their web page here:

PS. If Kennedy's Dynotune is using that New Age injector machine fresh out of the box to flow match injectors he will be doing his customers a BIG disservice. That machine along with most others such as the Asnu that are designed for general field service do not have the capacity to accurately flow test and match injectors without major alterations to both the electronics and mechanics.
