for what im gonna be running, will the stock radix inj. be enough? what size are they. i was told 42lbs, is this correct? i will be running 10psi, with meth.

 

They'll be maxed out. 60lb injectors are recommended.

good luck,

well that sucks. do you know where i could get some for a descent price. also you say they'll be maxed out, does this mean it will be hurting me or just limiting my power? im looking for 500rwhp, is it a necessity that i get the 60lb inj. to meet this goal?

 

If 100% cycle is considered maxed out, yes, they will be maxed out.
I have seen trucks run on 100% cycle just fine though.

I'm sure you can reach 500hp with 42lb'ers on the dyno, but I wouldn't recommend a 1/4 mile pass or an extended run, the injectors will definitely be too small, imo.

You can also detune the truck, low on timing and low on rpms, that will get you by until you upgrade.

good luck,
allen

 

Would his meth not help take some of the burden off of the injectors? seems like I have seen lots of peeps on here with 500rwhp at 10psi with 42s and meth running at less that 100%....?

 

Ya, it'll patch the fuel system until he's ready.

 

So , I just shot myself in the foot ordering the 42's huh

 

Parish once said that his inj duty cycle dropped by 30% when running a **** load of meth

that sounds like what im gonna have to do. cuz i aint gonna change them yet.

 

I'm in the 600 rwhp range with 44lb flow matched injectors. I spray meth at 8psi and up. I've had 60s for about 4 months. Hav'nt had time to put them on yet.
