Cleaning Injectors

[Roy]

Ok name is Norman Andrews Automotive Repairs, in Richmond. Ph. 4588 5777

Receipt reads: Check injector, fuel flow and spray patterns, ultrasonic clean injectors, replace pintle caps and seals as required.

I also got a sheet listing before and after flow, spray pattren and leakage.

The after results list spray pattern as good, leakage Nil and flow improved and equal across all injectors (contrived, typical i dont know, it could have to do wiht the method of test????)

Reason i went there is i have often seen imports there (he brings them in occassionally) and runs a well presented/ neat workshop.

Apart from the injectors all having the same after flow value, is that normal, i would assume a little variance is typical, im happy.

Oh and Dan, dont worry, when my engine lets go and dumps oil all over the track on turn 1 after 3 laps, you can drift past me aided by the oil slick courtesy of my humble little RB20.

Did you get like some kinda dyno type printout of a before/after of the flow etc ?

Be interesting to see the difference.

Does the fact that they all had the same flow after the cleaning seem a little rehearsed??????????????

Still at the very minimum they have been cleaned and are all working properly so wont cause my engine to let go when installed.

What's the measurement mean ? 110 what ??

Sorry for all the questions. I thought flow would be in cc/per sec/minute/hour or whatever.

Thanks Roy,

Same ere, still though u got atleast a 10% better performing Injector after having them cleaned so it should be good.

Hills motor sport does a great job

[Brody]

how much?

[JiMb0]

I'd be interested in how much hills charge, I'm about to get the car dyno tuned at hills and might aswell get the injectors cleaned first at the same time.

How much would it cost to clean carbies, i got a civic twin carb.. im stuck with it till i get cash for a skyline, suppose some extra grunt wouldnt hurt, getting extractors put in for $150 air filter isnt possible on my 1 i dont think

i got some fuel cleaner too, some red shit u put in petrol
