Ok, I am running out of fuel. I have 42lbs injectors,inline 255 and the stock pump. I was thinking that I would just run another 255 intank, and put a hobbs switch on the inline. Set the switch for 10 psi to turn on the inline pump. I will also be adding 3 bar map sensor to the alky, and another nosle for more meth at 20psi.... Do you guys think that will be enough? I do not want to change my injectors that will change my tune. Do you think I will be ok like that?

 

I am running out of fuel at 4500rpm

 

What is your injector duty cyce at 4500rpm?

 

I was not loging on this run, but the last time I asked rick he said 80%. I was not running as much boost at the time. The tune was set up for 15psi at that time. Dam! I think the injectors at this power level would be maxed out. Do you guys think I could get away with just using more meth?

 

I would really doubt that your running out of fuel pump, but injectors on the other hand, I'd put money on that. At that power level, you really need 60 pounders. You could run a second meth nozzle, that would help, but you should really look into bigger injectors.

PS, if you want to sell the injector you have now, I would be interested. PM me.

 

You could probably do it but it would be risky. Are you prepared to lose the engine should the alky fails?

Good Luck!

 

You really need more injector and pump to be safe.

 

get some bigger injectors and sell me for 42 lb injectors haha

 

I already called dibs, lol

I got a 5.3 going into a '72 with a turbo I need them for.

 

when you say your running out of fuel, does the truck just shut off then runs again when you let off the pedal for a second or so? im betting this is happening in 3rd?

i mean as shut off all guages start to act wierd and if you let off the pedal time passes and it regains its position?
