I think those are low impedence.

I run an Acceleronics Versafueler with 84 lb/hr on my stock ECM.

I believe RC Engineering makes a 75lb high impedance injector. There was a set for sale in the classifieds around a month ago.

RC's 75 lb injectors are the biggest that I know of.

The do some custom work though, so they may be interested in building (ie hogging out) one.

If you need that much injector do it right with a Low Imp injector. Much better control at that volume.

Ugh i missread the thread title. eyes saw one thing brain saw another.the largest High Impedence injector that I know of that actually works halfway decent is the 60pph mototron/siemens unit. It flows 72pph at 60 psi of fuel pressure. Its base rating is at 43.5 JIC you didn't know.

The RC injectors every set I have ever seen are absolute junk. that pintle design bosch injector really get hairy aroun 50pph on a small engine. Not to mention its very poor dynamic response.

Stick with PICO style High Z injectors or switch to Low z.

If ya run a BS3 then Low impedence is a Non Problem.

I am running the RC Eng 75# and I love them.
