Thread: Gen 111 injector results

I am a bit surprised of the results there...

Any thing under 14/100 is still good I think if you have more usable Power and torque with it

Your surprised, 13 liters on the old black tops blew me away!!! ... My point of view is that I have manage to get this motor from 20 litres per hundred .. to 13 is outstanding ... AND the injectors are 300tho k old ... well beyond what I would have considered it's use-by date

The day of test was .... Flat ground rolling road ... No breeze / cool day 25c

I did a "0 to 100 test" and got 11 1/2 seconds (sub 12) ... yet to repeat it on the Gen 111 ... But will later

Yea thats what I ment. Suprised how good on fuel. Under 14 is better than some oilers around that vintage and newer.

Just finished installing mine tonite.
Off the boot, BIIIIIIIIIGGGGGG difference driveability wise!!!

Power is definitely up, smoothness is humungously better, idle is much smoother, responsiveness is up, overrich fuel smell at idle is down, exhaust note is different at 3000-4000 rpm but due to my new found joys, fuel economy will be down for a bit until the happiness recedes in my shorts!! .

Think a full tank run would be a better gauge of results.

The best run I have had on an unloaded country trip was 16.65l/100km, my normal round town figure has for quite some time been between 19.7 - 20.8l/100km based on figures i have been putting into the "Fuel Gauge" app on my iPhone. Most of this is the morning work crawl I have to do of about 30k's each way everyday.
Will probably demolish the best part of this tank but will start putting up some results.

As Rangier said too, if its only up that minimally but power etc is significantly up, its not such a bad thing.

The one way to make it even better is to install oxy sensors which will most likely be the next major thing on my list to do.

Cheers

Maybe I missed earlier threads, but this is all news to me.

Now I have something else to do!

As I said earlier , I expect that you will have more smoothness with the Gen111s as I had with the Gen11's but won't see much in economy.

Remember you are comparing against OLD Lucas injectors which may drool, be partially blocked etc etc.

BUT it highlights that injectors are wear items and maybe should be changed at maybe 160KK, especially if the ECU does not have o2 sensors and self correction for injector flow changes.

... Jon ... as they say .. Just do it ... You WILL be pleasantly surprised

There is a definite power increase & the motor is very lively ... I have put a 2 core wire with a switch in parallel with the motor temp sensor ... On the 2 core wire I soldered in a 300 Ohm resistor ... So now I start the motor with the switch off (gives me the Cold start Ohms off the Temp sensor) ... then flick the switch to the resisted wire ... which measured 260Ohms at the ECU plug .... I "think" this is telling the ECU to lean the fuel flow // Hence my economy was below 14L / 100 on the Lucus black tops

I will see where I can get injectors.

They are just Commodore Chev Gen III injectors? Straight bolt in fitment?
