Do you know what type of injectors you are running? Disk or pintle? Any problems with them?

Thanks, just doin some research,

Ron

 

not sure on the type, no problem with them at all other than i am nearing their limit. i am up to almost 80% duty cycle. 408 is going to push them prety hard.

here is a link to them and the place i got them at http://www.racetronix.com/3172FM.html

might be selling them if anyone is interested.

 

I may be interested in them if your getting rid of them. How much is involved in tuning them to run right, and not flood out the engine?

 

just a matter of finding the right injector flow rate. you should be able to use the calculated value but that seldem works for some reason.

you just put them in, enter the calculated IFR number and see where your ltrims go. then adjust the IFR till your ltrims get close to 0

 

hey parish snakeater and myself are working on this for my truck. how much would be wanting to sell them for. do you think i could tune them to idle good in my 4.8. my goal is 400rwhp daily driven but i want room to grow. snakeeater don't think i can get 400rwhp daily driven. but we will see.

thanks for the help.

 

when i am ready to sell them(thinking about 1 month) i am going to try and get something like $325shiped. they will run fine on a 4.8 and will support 700rwhp easy. these are the biger style and do not plug right in, the largest you can get that plugs right in are the 43lb marine 8.1 injector. that may be an easier way to go with your set up and still have some room to grow.the 43's are good for at least 500rwhp.

couple things to keep in mind, the 43's are rated at 59psi wich is our fuel presure so they flow an actual 43lb's. the 57's are rated at 43.5psi but we run them at 59psi so they flow closer to 67lb's.

here is a swap page xlr8nss put together if your want to goto the biger injectors >> http://hauln.net/LS1Tech/truck/fuel_injector/index.html, it really isn't that hard and only takes an extra hour or two.

 

cool i never read that before. hell yeah let me know when your ready to sell them i'm hoping i'll be ready for them bout the time your ready to sell them. i may be asking a few tuning questions for them once i get every thing together. so do you think i can manage a safe reliable 400rwhp. thanks for all the info and yes i would like them injectors please.

 

Hey Parish, you are running your trims around zero 0? I was under the impression that -2, -3 was a better target? Or is zero better for your application? Sorry to ask so many questions but inquiring minds wanna know. BTW, I am running HP Tuner software, stock O2/narrow bands, on the motor listed in the signature.

 

Dibs on the injectors if you guys decide you don't want them.

 

don't worry i definatly want them. just waiting on my bonus thats all.
