Default RC engineering

Sent my injectors out Monday from a middle-of-no-where post office after pick up time, asked about them yesterday (Thursday) and was told they were completed and already in the mail Haven't arrived yet (Friday) but they're only going from California to Oregon, so I expect them tomorrow, unless UPS delivers late.

Total not including the ~$6 to ship to them was $94 and change. Looking at the results, the quick turn around time, and the very nice customer service, I am an INCREDIBLY pleased costumer. If you use them, don't forget to mention mt.net for the 10% discount.

When I emailed asking if they had received them and was then told they were done, I asked for this electronic copy, so if you use them, don't be afraid to be as impatient as I was and annoyingly ask for the results.

**Didn't see an RC engineering forum, so if there's a better place to post this, feel free to move it.

Wow...good results. Makes me want to send mine off seeing how far off some of yours were.

I don't think they care, rc injectors or anything else. They were RX-7 injectors. They actually figured that out themselves, as I had told them my car was a miata, wasn't thinking about what car the injectors came out of. Man I'm illiterate after 2 beers...

Nice. So you might have installed a dripping, <440 cc injector in cylinder number 4, had you not done your prep work and had them cleaned. Awesome.

Actually I did install them, and had 2 cylinders cutting out randomly. I blamed my COPs harness, but finally figured out it was the injectors. Put my 265cc 1.8's in and it started working awesome, so the 460's were sent out.

Brand new RC injectors have a 1 year warranty - I sent my 750s in after my motor blew in November and they cleaned them for free.

Damn. All four within 1 CC of spec?!? Amazing.

R-comps, real ecu, big injectors, well over 100,000 grams added lightness, you're gonna be tearing up the track this year.

Yeah. Deatchwerks promises 2% +/-. Those things are (point) .2%!

Man i'm sending my 550s to RC now. I'm pretty sure injector rehab didn't do a very good job on mine.

I'm sure RC would say, as with all things, "your results may vary"!

This! But at least they appear to be promising though...

More good news, they finally arrived today. Not that it took that long, about a week after she said they shipped, not bad for paying for the cheapest shipping they offered and having a weekend in the middle there.

Clearly labeled 1,2,3,&4, very VERY clean (spotless, literally), plastic caps over the feed hole, new top and bottom o-rings (top o-rings can't be seen under the red caps), and a little baggy with four new spacer thingys. Individually wrapped in bubble wrap baggies, which were slightly over sized so there was at least two bubble wrap layers protecting my injectors during shipment, along with the cushion of the baggie next to it. Oh, and a RC FUEL INJECTION sticker plus a hard copy of the results.

I'm going to go install them now in this 45* weather where's my global warming? The labeling is nice too, if I keep them in order I'll be able to see which one started to fail first and blow my engine up when I pull a Savington.

As I stated before, very satisfied customer. Did I mention these things look brand new? ZOMG.

And yes, results will most likely vary, I'm sure I got lucky. But then again they took one from 437 to 459. 2% is 451, which I would not be satisfied with.

Cueball, I'm planning on quitting my job and returning to school full time possibly as soon as June, so I'm not sure a track day will be in the picture. Hopefully I'll be able to squeeze one in, might be a rainy one though. Normally I wouldn't mind since I don't have to worry about cooling issues. But I got rid of my all seasons! Damn R-comps.

Went from running car to a leak tested assembled one in 20 minutes, I'm getting good at this! Took a bit to get the lap top hooked up and going, as my ac adapter didn't have enough juice to power the laptop with the engine off. Which meant running 460's when the MS thinks I have 265's, and it ran like crap. But it generated 14 volts and as soon as I changed my required fuel it ran incredibly smooth. Unfortunately going from a closed throttle to anything but is pretty choppy, something in my idle settings must need changing with these bigger injectors. Just got back from my last data logged N/A run, brought my MBC in, and I'm off for a boosted run, wish me luck!
