larger high impedance injectors

[496chevy]

i've been looking for some larger injectors, right now i'm running rc racings 750cc or 72lbs/hr @ 43psi. i'm running 60psi and don't want to run anymore fuel pressure. I know you can get a conversion controler to run low impedance injectors but was hoping that there was something around a 100lbs/hr that was still in a high impedance in a bosh stile top feel injector.
thanks for any info.

Dont think i have ever seen a high imp 100 pound injector-

I believe the biggest high impedance (12Ω) injector is 72lb/hr.

[MSURacing]

These are the biggest ones I know about.

They are very hard to tune at idle though, I don't think you can run under a 3.7mS pulse width.

Update courtesy of MSURacing: 79lb/hr is the biggest 12Ω injector so far.

They will be over 100lb with 4 bar surely?

[MSURacing]

At 4 bar, 58psi, the 79 lb/hr's are a little over 91 lb/hr's.
They really get hard to do a good idle cal with though, you are lucky if it will run at 11.5:1

[joecar]

We're assuming the rating "standard" (if it can be called that) of 3 bar.

Check the RX7 1984 or so... I believe it to be 100# and its high Z

its a pita to tune injectors

[ringram]

How about these too http://www.racetronix.com/3105FM.html
86lb/hr at 3bar!

Nope... those are 2Ω (low Z) injectors, sorry they don't qualify. :)

thanks for all the good info. i just found these injector that are 1000cc and can be run up to a 100 psi if you were so inclined. they are still top feed but aren,t bosch style but you could modify your fuel rail.they almost sound too good to be true, here's the link. http://www.t1raceparts.com/ProductDetails.asp?ProductCode=B1000S&Show=TechSpecs

sounds like some bad ass injectors, i want some!!!

forgot to ask what project is this that needs these kind of injectors you are talking about-
