THERMAL REDUCTION BLOWER SPACER PLATES
Thermal reduction blower spacer plates featuring 1 piece custom o-rings help to reduce heat transfer caused by the supercharger sitting directly on the cylinder heads and spacing the charger up off the valley of the engine. The supercharger being in direct contact with the cylinder heads and sitting directly over the valley of the engine reduces thermal efficiency and heat is always the enemy in positive displacement superchargers. With the Thermal reduction plates the blower will operate significantly colder, reducing heat soak and increasing consistency. The air entering the combustion chamber will average lower temps and be denser, allowing a HP gain and when tuning more ignition timing thus again more HP.
WHAT ENGINES AND SUPERCHARGERS DO THE PLATES SUIT?
The plates will have a very dramatic effect on downwards discharge style blowers as they suffer the most from heat soak, they also have a temperature reduction on upwards discharge blowers such as the LSA and Heartbeat. We have noticed with the LSA blower combined with our interchiller that that entire blower absorbs the cold temperature not just the intercooler core, this results in faster recovery times after wide open throttle and lower intake temperatures. So both upwards and downwards discharge blowers benefit from the spacer plates.
The plates suit LS3, L77, L98, LSA, LS9, LS1,LS2 style cylinder heads the brand of supercharger will not matter, the plates are 10mm thick and will raise the blower up by 10mm so check to see if you have enough hood clearance before ordering, 10mm isn’t much so they should clear most cars. You may also require a slightly longer drive belt, in most cases your current belt tensioner will have enough room to allow the increased height otherwise a ½ size increase in belt length is adequate.
When the plates are combined with one of our interchillers the intake temperatures are reduced even further as efficiency is improved even further.
