I competed in my second auto x yesterday and after being on the limit of second gear a few times I want to install a rev limiter.
Does anyone know what I can safely push a 2.7RS spec engine to? My car has an MSD 6AL ignition that takes plug in modules in 100 rpm increments - so 6900, 7000, 7100 etc. Thanks John |

One further thing to note. A lot of engine builders set up the valve springs to the factory heights without checking the seat pressure and open pressure, with dire results. My experience had been that with that a good set of factory springs and an S cam it will not rev to where it is supposed to without increasing both seat and open pressure to avoid valves bouncing.
Cheers, |
