What hp levels should I be able to support (safely) with the following fuel system?

Returnless system
255lph intank
Kenne Bell boost-a-pump
60lb injectors
stock lines and rails

BTW: there are future plans to build a sumped aluminum tank to fit in the stock location while still utilizing the fuel level sender. Also allowing me to convert to a return style fuel system. If anyone is interested in this please let me know as I will likely need all the help I can get.

 

I don't think you're going to want a secondary fuel pump in a returnless system.

 

Who said anything about a second fuel pump on my returnless system. IF your refering to the boost-a-pump that is a voltage booster not a pump.

 

Oh, cool. I've never heard it called that before. That would certainly be helpfull for the fuel system.

 

60#s are good to 740hp at the crank, assuming: proper fuel supply (looks like you have that covered), 80% IDC limit, BSFC of .60, and 58 psi of fuel pressure. You are probably going to be a tad higher with the boost-a-pump, but its better to estimate low for injector support than high...

 

I'm not sure the single 255 will be enough even with the BAP, that is assuming the ugly belt slip deal with higher hp ATI setups doesn't pop up. I've seen one pump(hot wired with full alt voltage) take people to 600rwhp(6 speed). I think Ranwalk knows a little about how to cure the belt slippage thing though.

So you guys think a single pump will be enough?

 

I say go larger than the 60lb injectors. You should be able to max those with a D1 on a 408. I would also look into doing twin intank pumps with one on a boost refernced switch to come on only at a set boost since you are returnless. I dont see a single pump and a boost a pump supporting the hp that combo should make, unless you arent going to push it to its full potenial.

 

is doing the twin intank the same on the returnless as it is with the return style. what im asking is the intank module the same. how does everything wire up, like with the switch.

 

I thought running a boost ref pump in addition to an intank pump on a returnless system was a no no? no?

 

boost ref pump? You talking about the "boost a pump"?

A boost-a-pump(BAP) is a device to increase voltage to the single intank pump.
