Bosch 803 injectors efi

[motec6.9]

Hi guys just letting you know that my silver 6.9 which is fitted with motec injection computer is currently running Bosch 803 injectors from a 944turbo i am currently talking to the guys at Kwinana Performance and Motec about changing to either the 968 or 012 ev6 injectors as they have a better spray paturn this is the formula used to work out injector size 286/8=35.75 x 5.5= 196.625 cc flow rate 803 flo 286 at 3 bar o12 320 at 3 bar going on that my 803 should be able to flo enough fuel for 406hp and 012 can support 465hp hope this helps anyone thinking of converting to efi

Thanks Motec.

If someone was thinking of going forced induction, say Supercharger.. would you recommend going to the Bosch 363 injectors??  They're rated at 560cc / 100hp per unit.

Also, do the Bosch 803 / 330cc injectors fit straight in on the M100 heads?  or does it require some modification to fit them?


Cheers,
Cam.

Sorry.. 1 more thing - found these guys.

Here is all their injectors that are 14mm - would any of these be a direct fit?

Hi Cam its a public holiday in Perth today i have to go to workshop tomorrow will have a look as it was 7 years ago i cant remember what machine work was done and i can ask Kwinana Performance as they are refitting my mod manifold to engine as for blown the formula for injector size is from bosch 286 in the formula is euro hp of your motor so 286/8=35.75x5.5=196.625 is the smallest injector flow rate you could use so work out what you think your engine will produce and what the cc comes to is the min you can use in flow rate

That's great, thanks Motec.  I can workout what I need from that formula.  Let us know how you go with injector size - it'd be nice if they're a straight fit. 

Soooooo keen to see some pics of this engine bay!!!  Hurry up mang!!  When's the dynotune happening again?
