what size should i use on the walbro pump and ati sc?

 

Each added psi is 6.8% more air so this is a good rule of thumb.....6 psi ~~40% more fuel.

 

I would say at least 440cc. I'm eventually gonna go with the 550cc RC injectors when I get my Walbro and go with the 2.87 pulley on my Vortech. But that's a few months down the road.

 

yeah ill prolly go with 550cc injectors. ill be pushin around 7psi. wheres a good site to get them?

 

Anyone know the difference between Deatsch Werks and RC? Any preferred brand? I was told by 98Intrigue to get 650cc injectors for my vortech tuner kit. . .wouldn't that be a tad overkill? I thought 440 or 550 would suffice.
