Anyone who doesn't follow FB. This I tested my new K04 super hybrid. So what's different to your normal hybrid. 1) custom made billet 7+7 compressor wheel , same size as existing hybrids but an extra pair of blades 2) custom made larger turbine extending the original inducer on the turbine from 50mm to 55mm and 5% bigger exducer. 3) custom made 15psi actuator. Initial tests show that the hinder of surge with the old hybrid has now been eliminated.. This has profound impact on performance as where by the old hybrid needed to be throttled back below 4750rpm to ensure surge didn't occur we can now throw in 23psi boost straight with no surge.. This can be made between 3k and 3.5k and held till redline meaning in the rpm range from 3.5 to 5250 rpm an equivalent potential of 50bhp can be made extra over the existing hybrids.. This is still early stages and more testing is planned. This is the old hybrid v super.. Improvements in maf and boost..
