I have talked to some members and received the advice that I need a fuel pump with my new mods (cams, full exhaust,uicp,licp,tune) I talked to my parts supplier and install shop and they said it is not necessary until I am making more power, such as a turbo upgrade. I know you guys know everything about evos, so I would like to know the benefits of a aftermarket fuel pump? Is it overkill? Does it help with power? Thanks in advance.
I drive a IX MR.

 

its a cheap saftey investment i would do it regardless

 

iono what ur supplier is talking about but you DEF need a fuel pump...especially wit a tune...Do u already have a tune or planning a tune?...but no matter wat u def need that fuel pump wen ur makeing more power

 

When you get tuned, the stock fuel pump will be maxed out and will be stressed to the point of premature failure, so a whinebro would be a great investment.

 

Simple test.

Do a simple data log. 3000rpm-7000rpm. RPMxIPW/1200

Anything above 95% then you'll need a fuel pump...you'll need one anyways eventually. I've heard the IX stock fuel pump is a little better than those on the VIII's

 

yah ive heard that the 9 pump is better but i would try it over a 80 dollar part

 

+1 with replacing with a walbro or something to that calibur.

 

get a walbro for sure
