Which Are The Best Injectors

[Ekul]

Got the Bosch 986's fitted and a re-tune - what a diffrence!!

Have noticed that I get a few really good hits of accelaeration when the boost comes on, but then that dissapears after two short bursts or one more prolonged spurt - presumably intake air warming / heat soak etc?

Have got the plazmaman inter-cooler stage 2 (upto 800hp)kit and the race airbox coming and also a 4" dump with a high-flow cat, hopefully this will remove the flow restrictions and cool things down a little. Also have Process West surge tank and motorsport 044 pump c/w harness at home waiting to go on.

Will hopefully get all this stuff fitted and dialled in this week, or next, depending on when the postie drops the rest of the stuff off.

What sort of rwks can I expect from all of the above on my 2011 FG XR6T 6sp auto ute?

Almost everybody on this forum seems mad keen on 60lb Siemens Deka's; was wondering with my above Bosch 044 pump and Bosch 986 injector set-up and all the other above bits and pieces fitted, what would be a realistic performance difference if I spent another $450 to swap out the Bosch 986's (42lb) for the 60lb Siemens Deka's?

Was quite happy with the recently fitted Bosch 986's by themselves - you wouldn't realise just doodling around town that anything too much was different from standard (though much better economy around town), but as soon as you start and squeeze the accelerator - it turns into a differnt ute with phenomenal acceleration until presumably things get a bit warm under the bonnet and it loses the boost feeling - on cool morning/ evening, giving it a bit of a squirt above 100km/hr gets it up to big numbers on the speedo pretty quickly, till the heat kicks in and takes the boost effect away on succesive attempts, till it cools a little.

Is the difference between the 986's and the Deka's huge, or will I be happy with everything once all the other bits are fitted?

With all the mods done you will get approx 300-320rwkw.Going to the dekkas wont gain anything as you will be at the max limit of your turbo. The 968 injectors will close to max aswell but should be ok. Tuner will be checking duty cycle one would imagine.

Yeah I have the green top 42lb injectors in my BF and they are nearing capacity at 317rwkw, haven't logged duty cycle though but I expect they are at 90%. I chose them to have better idle quality as vs the Siemens 60lb'ers.

whats everyone think of the 80lb deka's over the 60's?

Will I notice any difference?

the first stage of my mods I expect about 330 atw, but will stretch it to 375 later on.., am I best of just doing it once and going for the 80lb'ers?

[discostig]

If you're spending the kind of dosh that 400rwkw needs, I think Injector Dynamics would be a better bet? ID1000s? Would be good to hear from some with more expertise.

60s will get you to 400wkws, 80s will go high 400s... ID1000s 500+

if your going to stay under 400wkws then the 60s will be fine... BUT, if your thinking of E85 later on, get 80s as they support 450+ on E85.

968s on an FG with stock XR6 / G6ET turbo will be fine but getting to their limit.

60lb Dekas are popular mainly for their price and plenty of headroom for sub 400kw cars.

If you want a big injector that has terrific idle abillities, go for the ID's... even the 2000's will idle smooth as

[RAP1D]

...and the 55lb Bosch 3/4 length are apparently liquid gas injectors, so not really the best bet for petrol... they work, but can be tricky to get a smooth idle ect.

my mate has even put the 1000's on his 1.6 twin cam turbo (tuned on Envy's ethanol brew)

The big Bosch ev14's have a CNG origin but are popular with petrol and ethanol etc. The 52lb Bosch ev14 come stock on the GT500. Not sure what the 55'er's are but 52's are readily available.
