Just heard back from Falkland Performance.. Car producing 309bhp (up from 276) & 392NM (up from 357) with a sustained 1.2 bar @ 12.9 lambda but only 250bhp atw..(using an LM-1) I didn't expect such a large tranny loss?
Apparently boost is sustained with slight spike at 4000 to approx 1.25 bar which thereafter settles back and LM-1 readings look good after they adjusted the pressure regulator. Apparently pull is strong throughout rev range.
However - I have to feel slightly disappointed in those figures - Does it mean that the G H-Chappal map is not as good as we'd hoped on the fuelling side or that the car's set-up is a bit tired.. may be time for a new chip or to replace the LC injectors. Disappointing given the mods etc but perhaps highlights the fact that not much has been done to the internals of the engine other than some light porting.
I wonder if the stock Sport300 turbo itself is hittings its max.. D suspected that may be an issue. Perhaps the Freescan's MAT reading give us a better idea? If I have the tubby uprated I'm guessing I'll need a new map anyway but the fact that the boost remained pretty constant perhaps indicates that this is the proper pre-set level of the chip.
Will run some long Freescan data at next run and send on to see what to do next. What's for certain is that 309bhp and 392Nm will feel a bit different to 190bhp. Will post data and curves shortly.
