Aftermarket lift pumps

[revemup15]

Hey guys just curious what lift pumps y'all are using.... my plan is around 400-450hp.... I was going to go with a low pressure piston pump on eBay but I just read that they can only take around 300hp... any opinions would be appericated also.... thanks in advance

I use a raptor 150 and it is great! Easy to hook up also.

Normally how much HP can a raptor 150 support

If you want to stay mechanical you can run the P-pump LP with a boost-reference reguator, but after that mechanical stuff gets pricey. It should be able to support 400hp fairly easily.

:edit: From what I've gathered in the last few minutes, the P-pump LP runs out of steam at around 500 horse on a P-pump truck.

Thanks taco claw for the info.... are you refering to a stock LP on the ppump trucks?

I make 350hp on my LPPP.

they sent me the wrong lines, but other than that it was a simple install.
oh, and if you end up going electric with new lines, be carefull of the quick attach fitting on the top of the tank, i broke the nipple it attached to on mine

A Walbro 392 and external regulator serves my mess alright.

Keep them coming guys.... is there any that I or any other newbie should look out for when shopping for a LP?

Upgrade the lines to 1/2" and 600 is the top of the limit.

Well crap, guess mine won't be usable on my truck after all.

I typed out a confirmation to this I thought, must have forgot to hit reply.

Yes, the factory P-pump LP is generally known around these parts as the HPLP.

Ron A made 1200 something horses on a piston pump, he forgot to flip the switch for the electric pump to kick in.
