tonight desielgeek helped me swap out my 57lb injectors for some big dog 95lb units. the 57's were high impeadance and the 95's are low impeadance(requires a high current driver(part of megasquirt)).

the thing runs fantastic. it starts better, it idles better, it free revs better, the tuning is not course at all. made a few quick runs and my previous tuning is still prety close. it seems a little rich down low and a little lean up top. probably have to spend 1/2hour tweaking that if i want it perfect.

a short wot blast and i saw all of 54% dutycycle. that should leave me some room to grow

time for a new header and some nitrous, the nitrous will be a dry set up with megasquirt adding the extra fuel. i am prety sure i will be finding the limit of my fuel pump set up and the stock 3/8" feed line. i log my fuel presure so i should see it before i have too much of a problem.

 

Were you close to maxing out the 57's?

WHat's the stock PCM as far as impeadance goes? Low or high?

 

Yeah, I thought that if I ever got out of control and needed to run big injectors, I could use one of these in conjunction with the factory PCM: http://www.acceleronics.com/versafueler.htm

Seems like low impedance injectors are the way to go.

 

95 lbs fire hoses....... Holy **** you are keeping the iraqis busy making petroleum.

 

stock system is 4 bar, sounds like parish got 3 bar injectors

 

maybe i'm not reading/remembering that right but i'm to comfy to get up and check

 

That's good knews man!

Hmmmm I wonder......

 

stock is 4 bar ???...what exactly do you mean by that grippy ???

 

Just out of curiosity why did you decide to go to a dry nitrous setup?

 

4 x 14.7psi = 58.8psi

4 atmospheres of pressure, or 4 bars of pressure
