Fuel Injector Clinic 1GR-FE groupbuy (FEELER)

I’m in for a set of 445’s. Talked to them today and they have them.

 

And thanks @loginfailed i was gonna reach out to you about this soon, you beat me to it.

Mine idles a bit smoother and I believe @Roostfactor said his idles smoother too. He and I were running Siemens Deka 640cc injectors before (from URD). I don’t have a frame of reference on idle smoothness of the stock injectors because I haven’t run stock ones for a couple years.

The difference with flow matched injectors vs. not flow matched isn’t likely something you will notice on the butt dyno. It is a more precise match so that each cylinder gets the same amount of fuel. When you’re firing away at 5-6000 RPM you want them to be as close as possible for safety and smooth power delivery.

Normally aspirated 1GR = 330 cc/min
Supercharged TRD 1GR = 455 cc/min

It won’t hurt to go larger than you need. 650cc is the biggest most of us (99%) will ever need. There are some outliers (the other 1%) such as @Torspd who is I believe currently running 1300 cc/min injectors.

True statements on both points. Mine are 1300 ccm. Only if turbos, large rotrex, or larger liter twin screw blowers are installed will a larger set be needed.
More pounds per minute of air equates to more HP potential, which in turn means more fuel requirements.

P.S. which likely also means rods,pistons, and head studs.

 

@loginfailed So just so I understand this right - These FIC injectors coupled with the billet fuel rail are not so much power gainers but more of a safety net from lean out conditions ?

 

Yes exactly

 

So what size should I get ? currently I'm just running the s/c on the stock pulley, but piecing parts together swap to the 2.8", as well as 3 deg cam gears

 

650s hands down. Or bigger

 

650 cc/min will support up to 600 at the crank.

I have the FIC 650 cc/min injectors with stock air cleaner, AFe ProDry drop in filter, supercharger w/2.5 pulley, headers, JFR y-pipe, 1141 resonator and TRD exhaust. My injector duty cycle last I looked was about 65% at WOT 5500 RPM. When I had stock injectors on a similar setup, the duty cycle was 95% (very scary, lol)

 

Yes!!! Im in!.... Put me down for the 650’s. Thanks for putting this together sir

 

Got it!

 

Put me down for the 650's then..

so what happens when the injectors hit 100% duty ? full lean out ? Ka-boom ?

 

So what happens if I just run these injectors and no billet fuel rail ? what is the advantage of adding the billet fuel rail ?

 

Bling, and a bigger well to draw from so more consistent rail pressure.

 

There is no problem using the stock rails. That’s what I’m currently running.

This right here ^^

 

I’m in for 650s

 

There’s got to be more than 4 of us that missed out on the first round. We need to make this happen!

 

I’ll add you to the list!

Spread the word!

 

5 more!
