My biggest wonder about the Kremer's, RUF, and factory Group B is how they handled the CIS fueling and AFR's at 1.3 bar?

350whp is within the fuel deliver capacity with maybe a little lower control pressure.

However, 1.3 bar would put it over the edge quickly.

RUR, Kremer, and the factory (Group B) had some tricks up there sleeve and it was more than lower control pressure and mildly bumped system pressure.

RUF has some type of what looks like a fuel pressure reg on it. Never figured that one out unless it was to lower control pressure some way at higher boost levels or to protect some of the early WUR's from rupture (a known issue).

I am sorry but I truly have to believe it would include the profile of the metering cone (as seems to be done on the 3.6T) to work at such air flow numbers.

I love this stuff a little to much.
