As above, what is the maximum power safely achieved running 8 dark green (803) injectors??

Forgot to mention Cosworth YB Turbo

cameron2

What spec is the engine?

crazycage

about 600hp .

Running 605 bhp on 4 no 1000cc injectors, want to swap to 8 no injectors to get good emissions on idle and better low down driveability, i know most mappers dont like missmatching injectors i.e. 4 no greens 4 no grey etc.
I assume this is mainly due to most of them having a base map for 8 greens.

Mark Shead

4 1000cc injectors should have good emissions if mapped correctly and the engine spec allows it,
What make injectors are you running and what make ecu.

Give MSD at Blackpool a ring and tell Stu what you need!

Hi Mark,
Currently on P8 with mountune ALS board, injector make i cant remember, they are half black half silver, i have purchased a T62000, the engine will be re mapped for the T62000.
I have been told that the emission levels would still be high for a MOT using the 1000cc with the T6.

iv just change from 8 greens to 83lb 4 of and it drives a lot smoother and lamba is on 13.8 to 14 when driving insted of 11.4

Mark Shead

What car and age as emissions will be diff for all the range,
I cant see why a T6 cant drive the injectors correctly as 1000cc are hardly big ones nowdays, who's the mapper.

I only need to make 3.5% co, it will probably get mapped by one of the local guys like Tom Field or ahmed Bajoo.

Mark Shead

At 3.5% you should piss it with any good Ecu and 1000cc injectors.

Thanks for the advice Mark, perhaps i will cancel that siamese 8 injector manifold i orderd today and stick with my existing set up.

i have all you need ie 8x803s and inlet and fuel rail if you need it pm me

easy work! our 83lbers can run less than 1% idle content, as mark said its down to the map

pauljh

What about MSD 1000cc injectors?

tabetha

I know it's not 1000cc, but I run greys, that some say are very high emissions, but as it has been mapped correctly it breezes the mot at 0.97% co.
I do know of 8 injector set ups(cossoes) running perfect, but again these are mapped correctly, last one was 8 greys.

Mark Shead

I have used these but there are far better injectors out there of the same size.

The Siemans injectors seem to be favourite, what make are you refering to Mark? I cant find Siemans injector in 1000cc, would the 83LB injectors be suitable for 600 bhp?
Thanks.

i would look closer at Rochester injectors, i believe they are 1008cc
if not then i would use the Siemens over the Bosch

siemens 83lb are 875cc.

LHD220Turbo

siemens:

55lb = 575cc
72lb = 750cc
83lb = 875cc

Rochester = 1008cc

The MSD injectors look the same as the Rochester, are they made by the same manufacturer?

i think you will have to ignore me; becuase i cant remember what injectors MadRod uses

thinking about it now; i think the rochester have got a shit spray pattern. I'm just trying to find the name of the injectors i'm thinking about

LHD220Turbo

iTrader: (4)

anyone know the name of these injectors?

Mark Shead

yes 3 standard yellows and one standard blue there where there just to block the holes.

Mark

Mark Shead

Yes they are the same and I dislike both.

Mark

crazycage

why what up with them ??

Mark Shead

1 is the spray pattern and then the most important is pattern and amount each injector flows is diff on most sets I tested.

Mark

crazycage

ive got 6 new ones would you suggest i get them flow tested?? i only need four for a zetec turbo.

Mark Shead

Yes get them flow tested.

didnt even spot the blue one

what make 1000cc (ish) injectors do you recommend, obviously not Rochester!

Mark Shead

RC engineering or Bosch.
