Ok, exactly like it says. how do you wire a whipple boost a pump if you aren't using the whipple computer???

 

heck i would run it like we do the inlines. hook it to a relay and then use the factory pump wire to have it turn off and on.

or i think parish is running a hobs switch somehow that turns his on. maybe he will chime in.

 

I wouldnt wire it up direct. I would put it on a boost switch because i think it would bump your fuel pressure to high at idle. Whith the whipple comp hooked up it only comes on under boost.

 

I spoke to Jeff at Whipple today and he says hook it up to a pressure switch(Hobbs switch). I didn't realize "hobbs" was just a brand name. So, I just purchased a pressure switch on ebay that hooks right into my boost line and adjusts from 1-4psi. I'll hook the boost a pump up to the factory fuel pump wiring as described in the whipple install instructions, then to the relay supplied with the whipple, then the blue wire out of the relay will go to the switch which is grounded. when i hit 2psi, the switch will allow the boost a pump to turn on and that sends something like 18v to the fuel pump instead of 12v. I'll probably burn out the stock fuel pump but I plan to do a in tank pump in the future anyway.

 

It sounds like you got it there Ya putting higher than built for voltage to an electric motor will prematurely wear it down. Just keep your eye on your fuel pressure down the road.

See, the guys at whipple aren't sooo bad

 

Ya, but they have this one cat there that can't type for ****! I was grinding my teeth just reading the paragraph (if you can call it that).

 

where are you going to install the boost pump. is it inline. if it is inline wont it have to work all the time or cause a restriction.

 

for clarification, the whipple "boost-a-pump" is not an inline fuel pump. it just sends a higher voltage to the stock pump at a sae amount of boost, determined by the pressure switch

 

ya they need proofreaders

So is the pressure okay now DenaliHD?
