550 to 600 hp which injectors ?

[Jamo]

Kind of the point the oem lines require the injectors to open longer to supply the right amount of fuel hence they go to a higher duty cycle and max out

[terrybullwon]

The reason people go bigger imo on petrol is they max out injector duty cycle due to poor fuel delivery on stock sized fuel lines

Bingo.......

A relayed Bosch 044 can close to max 750cc's, without fuel pressure taper.

To max 1000cc's I think you will need two pumps/fuel line mods.

And that with stock fuel lines? I'm just thinking of uprating my fuel lines... should I?

You did not run into a bad batch. They all start to do that eventually.
Especially after they've done 10k+ plus, the spray pattern basically does not exist at low pulsewidths.

Could explain my bad idle that won't go below 900 RPM...


On a slightly related note, as I am in the market - what spark plugs for 500 - 600 HP?

FR5DP work fine, so do NGK.
F5DP0R seem to have problems lately with the porcelain breaking.

Probably not, just relay the pump and fit AEB FPR. You are not going to make 700hp

[Thuppu]

Why change the FPR?

AEB allows more flow for return IIRC.

Yes had this issue at the 'ring last year with an OE plug

[Greg_S]

Doesnt sound too good, mine has always run better on Bosch plugs rather than NGK

625 injectors

Hi,

ebay No 370519010694

thanks roger

They're too short. You need adapters.

[Jamo]

Five o ones are direct fit no adapters

They fit plug and play only if they are with the "long" body. Normal lenght is too short and need adapters, also FiveO's EV14's.
