If I were contemplating this, I think I would want to ask Emre the
following:
1. Do you think 24.5 psi coming from a K24 flows as much air as a RS2 at
24.5 psi?
2. Does the setup you mention work because the charge air is so much cooler
coming from an RS2 in comparison to a K24?
3. You don't think increased airflow versus unchanged fuel values can
contribute to lean running?
4. Does the ECU somehow compensate for this?
At least get yourself a wideband A/F gauge if you're going to do it. I
wouldn't put much stock into what others do. For instance, did Tom M have
RS2 injectors on his motor? How about the AW folks? I bet if any of these
guys was to pull their plugs, they'd look crusty white-a sure sign of
running a lean mixture.
Folks,
He really doesn't need to worry. The mass of the air measured by the MAF
determines the mixture, not the turbo.
I used "stage 1" software (it was, in fact, a TAP chipset) and stock MAF and
injectors to break in my GT30R equipped engine. I have the wideband, and
there were no lean running conditions ever experienced.
He won't hurt anything.
Take care,
Dave
