i wanted to use a denso supra fuel pump in my turbo build because its quiet, and it would seem more reliable than a walbro.
my main concern is that the supra pump draws nearly 20 amps at 45psi and a walbro 255 draws like 7 or 8 amps at 45psi.

 

this is a idea i have had for months, just have not put my hands on the supra pump yet to see its size, power requirements are not a problem, just use factory power wire for switching on a relay and run a new power wire (i already do this on high HP cars using the 255hp)

 

yea the supra pump is significantly bigger (in pictures at least) we will have to see how to fit this soon...

 

 

for 99 bucks like most sell the walbro for, and for the hp it supports why go to a supra pump?

Like the old saying goes if it aint broke dont fix it

 

Might want to also look into a stock Evo 9 fuel pump, as far as i know its the highest flowing stock denso ppump. It can be bought for much cheaper also.

 

i know the walbro pump is good to 550 hp - and i have pushed them to 600 with a rewire and relay, but would not do that on a daily driver, but again at these hp levels the fuel line sizes are to small and need to be upgraded, so a real pump (external with modified fuel tank pickup is what really should be done) but getting a customer to spend a couple thousand on fuel system is hard to do.

 

sell the value of of going with an external setup, it should be a no brainer at 500-600 hp

 

I just re did my fuel system....i put my new fuel pump on tob of the stock gas tank and suck it up form the tank. Then i just ran larger line to the fuel rail. cost like 600 bucks total.

 

i really dont like hearing the fuel pump. thats all. if the walbro were quiet i would get it. plus the denso pump is only like 200 bucks whats another 100 dollars after spending thousands on everything else?
