Anyone know whats the max boost my 112 radix injectors can handle?when is the need for walbros etc etc?
I was recently running a 3.90 pulley(stock)5-6psi
i just installed a 3.70 now it runs at 6-7 psi i was expecting 8

so now im gonna try a 3.50 pulley-just wanted to be sure first.

The injectors will provide enough fuel to make about 500-525 rwhp.

 

Thanks -how much boost u pushing on that 4.8?

 

5 psi

 

Watch out!
