[s-cars] Alternatives to RS2 Injectors

[Trevor Frank]

Of course to get it to run correctly you are going to need someone to
correct the RS2 based software to run the larger injectors, hmmm.

Dave, the pressure increase calculation isn't correct, the right formula
is:

sqrt(new pressure/old pressure)*old flow=new pressure flow.

So this means that 36 lb/hr @3Bar injectors will flow 41.5lb/hr at 4
Bar.

Flow increase isn't linear with pressure increase, otherwise it would be

easy to install 3B injectors and run them at 5 Bar for 600 HP....

Siemens or Lucas 37lb injectors should be fine for you, they flow
exactly
9% more fuel than RS2 injectors at 4 Bar rail pressure and RS2 boost
levels.


HTH,
