I had to search for some rare 12mmx1.0 pitch banjo bolts for the fuel rail, and also figured I should get my fuel injectors checked and cleaned (just in case). I bought my DASC kit used and they came w/ NickG's upgraded Bosch 310cc injectors, and I wanted to have no doubts, and proper tuning when this car gets running (with NickG's stage2 program). Anyway, RC Engineering is right around the corner from my work, so I dropped the injectors off yesterday at lunch. 1-day turnaround gives a printout with before and after spec sheets, new O-rings, caps, filters, and makes sure they're all "matched". I thought the injectors would be fine, but I'm glad I had them serviced. Here's the results: (test @ 43psi) ------------------------------------------------------------- BEFORE CLEANING: / AFTER CLEANING: Inj.# cc/min- pattern / cc/min- pattern ------------------------------------------------------------- 1) 294.0- Dripping / 309.0- Excellent 2) 301.0- Good / 310.0- Excellent 3) 303.0- Good / 310.0- Excellent 4) 305.0- Good / 311.0- Excellent Can't wait to fire her up~ | | | 08-29-2010, 10:30 PM | #2 | Senior Member Join Date: Dec 2007 Location: Gulfport, Florida Posts: 3,208 | Quote: Originally Posted by JP422 ------------------------------------------------------------- BEFORE CLEANING: / AFTER CLEANING: Inj.# cc/min- pattern / cc/min- pattern ------------------------------------------------------------- 1) 294.0- Dripping / 309.0- Excellent 2) 301.0- Good / 310.0- Excellent 3) 303.0- Good / 310.0- Excellent 4) 305.0- Good / 311.0- Excellent Can't wait to fire her up~ | Damn that's a nice set of matched injectors you got there. Us guys in the real world have to pay extra to have someone go through a box of injectors and test them to match a set for us. Nice job Those should run real good for you. I always clean my injectors every 10 hours on my drag boat motors (over-kill). I just installed a set of matched 60# injectors on my car so I hope they stay clean for at least 10K miles. | | | 09-02-2010, 12:27 AM | #3 | Senior Member Join Date: Feb 2008 Location: Oceanside, CA Posts: 421 | Generally Bosch injectors are very consistent and there's nothing really you could do to balance them, unless as John suggest you go through a box and pick them to be close together... Not sure who the OP used for his service, but when I had mine services I used this guy: http://www.witchhunter.com/. He did an excellent job and the injectors came back with a similar report... __________________ 2003 Z4 2.5i 2002 Ducati Monster S4 | | | 09-02-2010, 12:47 AM | #4 | Member Join Date: May 2010 Location: CA Posts: 95 | Hey Luca, This is Joe (Joemamaman). Basically when I said they came back "matched", I just meant they were a good match set. No need to pick out different injectors, etc. I just dropped off the injectors for service "just in case", since I didn't know the history on them, and sure enough the cleaning brought them back to perfect "matched" specs. I'm going to drop off some 750cc injectors soon... and hope they come back just as matched as these. | | | 09-02-2010, 01:00 AM | #5 | Senior Member Join Date: Feb 2008 Location: Oceanside, CA Posts: 421 | Quote: Originally Posted by JP422 Hey Luca, This is Joe (Joemamaman).

Drop your injectors off and grab some Hawaiian food while you're down here. They have a 1 day turnaround time... if you come early morning, and request, maybe they can do same day? Looks like normal price per injector is $24 each. | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
