Updates?

 

Just installed the treadstone 342 today. Its a direct swap from the walbro 255. I was able to make it prime right away by leaving my fuel cap open upon first start up. I am also running a killswitch just in case , which would technically add more resistance, but its performing just fine. This pump is MUCH more quiet than the walbro.

 

noise isnt a concern, Im more for how much HP is can put up with. What was your reason for changing?

 

My walbro was starting to die out. I was hitting 13's on my wideband running E85 under full boost. Not safe at all considering idealy you would want to be around 10.9 to 11.1, at least I think.

As for hp they claim it can support up to 700hp on their website.

 

Pal I'd say you can run 11.5's and thats still conservative...
