Limits of RS2 360 cc/min (at 3 Bar) injectors?

[UrS4boy]

I was trying to compare 42 lb/hr (actually 43 lb/hr) Bosch Green top (non-RS2) injectors to RS2 injectors (360 cc/min or about 34.3 lb/hr at SG = 0.72) and bumped in to this RC Engineering website . Playing with the calculator there, if you run the 360 cc/min RS2 injectors at 86 psi in the fuel rail (4 Bar + 28 lbs boost), with 5 injectors, and a Brake Specific Fuel Consumption factor of 0.6 (low end of turbo engines), and a 90% duty cycle you can just get 360 hp, i.e. MRC Stage 3 software levels with RS2 turbo and injectors (actually you start with 360 hp and end up with 359 cc/min). To get to 380 hp (the top end of typical aftermarket RS2 software, e.g. MTM/Dahlback), those 360 cc/min RS2 injectors need to be running at 95% duty cycle, i.e. they are basically maxxed out.

Prj is your man

Afaik,yes 380 should be the max limit on 98 Ron fuel

And any Rs2 hybrid turbo will max them...


Does someone used them with 5bar fpr?

Yes, I hoped dmitri or Paul N. would confirm (or refute) what I suggested.
