You can test this by removing power from the LASAR system when the engine is running too hot...you will reduce CHTs by 30 degrees as the timing reverts to baseline. A plenum will help reduce cooling drag, but probably not make the engine run cooler unless you didn't fit your baffles well. fun fun, John -------- Life is too short to run lean of peak.

You can test this by removing power from the LASAR system when the engine is running too hot...you will reduce CHTs by 30 degrees as the timing reverts to baseline. The LASAR system will generally only increase CHT's by 15-20 degrees. http://www.unisonindustries.com/products/lasar_installation/lasar_inst_seven.html -- Walter Tondu http://www.rv7-a.com Flying!
