    Which injectors for around 450 bhp?

    Question, what is better: smaller injectors very near the limit of their duty cycle or larger injectors that are really too big?

    For around 450 bhp which would you fit (only from the choice below )

    440cc Bosch green giants ( as in Volvo T5)
    750cc EV14

    What do you guys think?
    Honda CBR 1100XX Blackbird Turbo....undergoing major changes.....
    S2 Coupe... bit easier off the line...
    '03 ZX12-R daily hack.... lots of nice bolt ons...

    Given that the ev14 are working quite nicely with motronic and aftermarket I'd use them. However you can get ev14 of smaller size

      I don't think Bosch greens will do a genuine 450hp so you need the 750's.

        Perhaps I should have mentioned - will be on Vems...

        My gut feeling was the gg were too small... I have both sets so ideally want to use what I already have...

              Or... would I really be better getting some 630cc Siemens ones...?

              Really wanted to use what I have but maybe not at the cost of sensibility...

                Siemens ones are ok but Bosch ev14 are ment to be better. I have got some 1200 c.c. ev14 injectors for my urq build and have been told idle is good with these.

                  I can offer you my used RC 750 saturated injectors... I used them in my 450HP setup with VEMS and had no issues with them... can also offer you my old VEMS base data for these injectors.

                  I changed them to bigger ones because of next power step...

                    That could be interesting - I saw in a different thread that you run with windows 8 tablet - it works well?

                    Would be interested to know more about that too!
