Injectors - Fyi

[boomer01]

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.

Regards,

Boomer

Part Number Delphi 01D030B (Lucas old 5208009, Lucas New 621031)

Static Flow Rate: 42.29 lb/hr @ 43.5PSI (300kPa) or 320gm/min

Static Flow Rate: 48.83 lb/hr @ 58.0PSI (300kPa) or 370gm/min

Dynamic Flow Rate: 9.96 gm/pulse - 2.5ms pulse width and 10ms repetition rate @ 43.5PSI

Coil Resistance: 15.9 Ohms / High Impedance / High-Z (No ECM driver modifications required)

Physical Dimensions > CLICK HERE <

Additional Information:

Top feed disc injectors use a small disc with six holes around its circumference. The disc rests on a short chimney that surrounds a metering hole. As the disc is raised off the chimney by magnetic force, fuel flows through the holes in the disc, over the walls of the chimney, and out the metering hole to form a full, finely atomized cone.

Performance advantages over pintle injectors (I.e. Ford / Bosch & Accel types) as listed by Delphi:

• The flat mating surface ensures that no excess fuel is present to evaporate and therefore, no deposits or clogging can occur.

• Compatible with alternative fuels (I.e. Methanol)

• Longer service life

• High-speed disc action allows wider dynamic flow range for improved idling

• Quieter operation

• Revolutionary disc design resists build up deposits which can affect fuel flow.

• No Fuel leakage for quicker starts

No mention of dual spray but the ohm's are incorrect for the XR6T..

Interesting though as it states 6 metering holes which should be better for atomisation .... I might investigate these as at that price its gotta be worth a look I think.........

They have a specialist Tuner in WA now ?

Everywhere I read they say no good tuners over that way? who is this tuner?

[F6_Tornado]

I thought id email these people and ask some questions about size spray pattern etc

this was the reply I recieved:

Hi F6,

The Delphi 621031 will replace the Bosch Ford SVO EV1 42# injector.

The body size is almost identical and the electrical connectors are the same.

The 621031 produces a fan spray pattern with three concentrated legs.

The best thing is to buy one set and try them out! I am pretty sure you will be happy with them.

S&H&I via Xpress Post to AU is apx $36-$42US depending on the qty you require.

Note: it’s not an EV6 but an EV1 and has three spray legs not two although I think that could be advantageous with atomisation.

This type seems to be similar to all the injectors that people are buying from OS but this is the best price I’ve seen .

Anyone game to try them out?

Maybe Boomer01 can post some details of his tune and what was the tuners thoughts on these compared to the BOSH 0 280 155 968 Dual spray/Long Body injector?

I’m sure if your tuner knows his stuff he should be able to give us some feedback please.

[bugster70]

I'd be very interested to hear some feedback too please!

I'm no techo so don't really understand the consequences of the ohms being different, can anybody enlighten me? But at this price, as F6 says, they gotta be worth checking out!

Thanks for bringing this to our attention boomer01!

Hi,

No problems RE the info on the injectors. As mentioned it was a forum member (Jordak) and Chipmaster (the tuner) here in Perth that brought them to my attention.

The following link details a dyno graph of my car with these injectors and a Di Filippo 3.5" turbo back exhaust fitted. The goal was to try and bring lots of neddies on early and by the way the car drives it certainly feels that way.

Anyway checkout the following link... (NOTE the dyno for my car is the second graph).

Hope this helps.

Jeeez-us, and you certainly achieved that goal!!

I can't believe the power increase you're getting at 3,000rpm, that's just fantastic. It would certainly seem that these injectors aren't doing too badly at all!

So, anybody got any more info about the different ohms, what it means, how it affects performance, etc, and why, if these injectors are supposedly the incorrect ohms for the T, they appear to be working so well on Boomer's car?

Isn't the 'tri' spray innefective in the XR head?? I would have though it would loose some 'atomisation' as it hits the 'splitter' because the fuel would form 'runs' like paint does, and not be as 'misty' when it entered the cylinder??

Sorry to be so technical, but u can see what I mean..

[F6_Tornado]

Probably no where near as bad as drilled out STD injectors.

Atomization is a result of forcing a fluid through a controlled orifice at a pre defined pressure. Drilled out orifice at the same defined pressure will result in les atomization.

I would imagine with the 3 orifice setup, two would be directed to the intake ports and the 3rd away from it centrally.

The advantage here is with the increase in cc and the addition of one more orifice atomization should be maintained at the highest level.

In simple terms 30% more fuel with the extra orifice per cycle.

This is presuming the orifice is the same size as the STD injector and with no addition pressure increase to the fuel rail.

which begs the question.... why not just get 968's?? apart from $$, is their another reason?
