anyone here have an apexi afc-r? I am going to get one but wanted to know if it would be a good tool to use in conjuntion with a walbro fuel pump and maybe a fuel pressure boost. I am going to be running a supercharger at about 6lbs of boost.

 

umm, that's not going to help you with a supercharger... only for turbo.

if you are talking about the s-afc then yes it'll help. but you'll need some bigger injectors as well.

 

Now how do you figure ti is not going to help me? A paxton nelson kit only comes with a fuel booster and that is satifactory. I am going a little higher. The most I will want to get is some tII injectors maybe.

 

I don't know what kind of fuel pressure numbers you need, but with the walbro gss341 you are going to be running rich most likely. You will need bigger injectors but I don't see why the S-AFC wouldn't work for you. Maybe Scott can explain.

 

Has anyone here actually used the apexi s afc? Will they for sure works with our cars?

 

The avc-r is a boost controller for a turbo. The s-afc is used to control the fuel (curve). What do you need? You would prolly be good fuel-wise with a TII pump and injectors.
