RC Engineering Injector Service Before/After results.

deephouse · 11-29-2007, 01:43 PM

Maybe this explains why I couldn't pass smog. High HCs @ idle due to dripping injector? I bet the dirty MAF (photos posted a few days back) has something to do with it also.

I'll wait till I get them back in the car before I say "I'm happy with the service" =)

the "fair" one flows more (may have had a higher A/F ratio = lean = pinging = retarded ignition). With the flow rates so even now, you will very likely be amazed with the smooth power. (At least I hope you are).

Good stuff.

Sent them Tues. Rec'd, tested & cleaned Wed, shipped out Today.

They include new Injector O-ring seals which run about $1 each on FAP but another $10 to ship makes that a $20 value. =)

Overall might not be worth it for you if you plan to upgrade injectors... Another $140 and I coulda just got the RS2 Reps from 034. But not going that direction....yet.

The previous owner went through this length being that other components of the car were in such terrible shape.

Being meticulous can be an expensive habit.

Bonus is you will make more hp now that... the "fair" one flows more (may have had a higher A/F ratio = lean = pinging = retarded ignition). With the flow rates so even now, you will very likely be amazed with the smooth power. (At least I hope you are).

Maybe even locally to us. __________________ Naturally, IMHHEO(tm), Dave F. aka the Librarian Car and Mods: 93 S4, 1.8t coil pack conversion (First in world using integral POS coil packs (??)), CF (OE), S6 steering wheel, RS2'd, Samcos, MRC, TDS-1, Apikol FMIC, Eibach/Bilstein, BIRA Sys 1, relayed FP Click here to link to the UrS FAQ Thread Start Uncle Dave says "You want my 'high horse, elitist' opinion ?(IMHHEO(tm))Then just post something stupid."
