What fuel injectors come with the Radix Magnacharger kit? They are 42lbs right? What brand are they if you know?
Also, what is the peak amount of boost you see with the kit without headers? (if you have a boost number but it is with headers, I am kind of interested in that number too)

Thanks. Ryan

 

I asked one of the techs at MagnaCharger about that and he said the only thing he knew was that they were 43lb/hr Bosch injectors. He didn't know what fuel pressure they were rated at though.

If someone with a RADIX kit could check there "injector flow rate" table with LS1edit I bet we could figure it out pretty easy.

Mine are 42lb Delphi injectors.Mine made 6 1/2 lbs with headers and 3.4"pulley,7 1/2 lbs with 3.2"pulley and 9 1/2 lbs with a 3"pulley.Those boost numbers are what I see normally the peak at 6000rpm is about 1 1/2lbs higher for each pulley.

 

I see about 7 1/2 psi with headers with the stock pulley.

I don't kwo what size injectors I have, but the flow rate is 5.25 all the way across.

 

Do you have an fmu with the radix blower or just use the stock feul pump ?Thanks

 

Radix system comes with Superchips programmer with special tuning for application.They also include a inline fuel pump.

 

About the inline fuel pump ... I was told by MagnaCharger that the extra fuel pump is there for high engine speeds. The stock fuel pump will keep up with the flow up to about 5k rpms under WOT, and then it starts to lean out.

 

5.25 works out to like a 42# injector at our fuel pressure. The RC Engineering injectors are about the same size. They are probably the same injector.

I guess that's the biggest injector available as a direct replacement.

 

Is anyone using the superchip programmer that comes with the radix? Or just junkin it and using Ls1edit or predator?

 

I am using the superchips program....seems to work very well.

I call Magnacharger today and they said that the injectors are 43 lb.
