Injectors - Fyi

[cqae]

As far as the ohmd readings go, they are directly related to the length & thickness of the wire used in the coil of the injector. longer coil equals more resistance, thicker wire less resistance, sorta like trying to push water through a hose. How it affect electrical circuits is as follow: higher resistance draws less current through it's circuits, specifially the driver transistors in the ecu. the lower resistance the more current draw.

So using a lower resistance injector in a car not suitable will draw to much currernt through the ecu & blow the driver circuits as happened on apollo/camry(same engine different injectors). 1 ohm should not cause any dramas though.

voltage also affect current draw as well as resistance-called ohms law current is directly related to voltage & resistance or some other crap I learned to long ago!

if they are just as good ...there are 500 good reason for these injectors

Looking at the injectors, the 3rd orrifice is centre, but aimed centre aswell. This would see the spray directed on the wall of the intake port yeah?? I know u can't really see from the pik, but I wouldn't think it's centre and aimed to either side either..

other than price.... I'm all for a cheap alternative..

not bad....

how do these compare to 968s??

From what I can gather they both are 42lb

Difference being Dual spray for the 968 and Tri spray for the other.

Ohms for STD is 14.5 ohm and the 968 is 12ohm, but this one is 15.5 ohm’s Resistance.

I think the 968 is a good injector but needs higher fuel pressure with only the dual spray so probably requires a fuel reg to match.

Trouble with all of this is you can never seem to get a complete spec sheet on any particular injector to plot its workings over variable conditions.

I think also these are similar to eugene’s spec wise.

Hi,

I upgraded the factory XR6T injectors 2 weeks ago now using 42lb injectors from a supplier in Canada.

The tuning specialist here in Perth (along with a Perth forum member) informed me of the following website...

http://www.racetronix.com

Details on the specific injectors I ordered can be found by clicking on the following link...

http://www.racetronix.com/621031.html

The injectors are a direct replacement for the factory items and don't require an adaptor plug 

Six 42lb injectors cost me $AUD298.48 plus an additional $AUD30.77 to ship them to Perth.  The injectors are $US34.99 each so the conversion to $AUD will naturally depend on the current exchange rate.  Shipping is $US14, however it will cost a bit a bit extra to send them to a destination outside of Canada or the US.  They took 7 days to arrive from placing the order (full tracking is available from the shipping company's website).

So total cost (inc. shipping to Perth) is $AUD329.25 (for six 42lb injectors!).  Had them installed and new custom SCT tune for under $700.00.

To date the car is running fine, safe AFR's and picked up 31rwkw for a total of 249rwkw (NOTE no inflated rwkw figures by allowing intake temps to increase giving a higher dyno correction factor...)

Anyway just thought I would post this info. as they may also be a viable option for other forum members.

Boomer

Hi Boomer

with these injectors what duty cycle are they at when producing the 249RWKW ? the standard one would be at 100%, just want to see how much potential they have left in them. It sounds like a very good buy.

Hi,

I'm not sure what the injector duty cycle is at my current rwkw level. I'll email the question to Chipmaster. FYI I was advised that they do have headroom for further mods.

Also they are much quieter than the stock injectors. The stock injectors make that ticking sound, however these don't

Boomer, the results say it all. Well done mate. You may have just found the perfect injector for the T. If so, I say we call them Boomer's Injectors. (Like Eugenes, but cheaper)

No worries. However like I said Jordak and Chipmaster here in Perth put me onto them and Chipmaster tuned the car, so all I had to do was handover some cash (I have only good things to report about about the tuner ).

As mentioned, if they work, are safe (whatever that means when modifying cars hee hee) and can save people a few dollars then all the better. I'll see if I can find out some info from Chipmaster RE the duty cycle and will be sure to let people know if I experience any issues with them.

One thing, I certainly don’t profess to know much about tuning cars so please ensure that you carry out your own due diligence on the product.

Boomer
