hi,
I have got an rb26dett with tomei cams 280 degrees and 10.8 mm lift. Now i was wondering what people set their valve (intake and exhaust) opening pressures at?
Mine was set at 90psi for intake and roughly 75psi for ehxaust, this was too high becuase after only 1100km's of running the engine in the cam lobes were showing signs of wear (really polished lobes just at the start on the up ramp on the lobe and the again at the peak of the lobe.)
Spring are tomei type c racing spring which has a inner and outer spring.
was thinking of setting opening pressure at around 65psi, also would people use double valve springs or just one spring shimmed up? Forgot to mention engine was built with the intenion to spin up to 10,000rpm
all opinions and feed back are welcome cheers.
