yeah ron not oct..
u sure vpower racing is 98ron? i thk its just still 97 with additive etc
our petrol quality sux but price ok ba :D
in need of higher octane!!~~
, thats why shell get away with it

hi bro gobiz, your rb26 runing 600 bhp or just the turbo rating can take up to 600 bhp (twin hks )right? people over here using ron 95 for 500/600 hp no problem, i been runing ron 95 my engine ok
jet fuel (usually used in turbine jet engines) burns hotter then automotive fuel, avgas (used in piston type engines) is similar to automotive fuel, the only difference it has a higher ron value.
if my guess is correct sir, ur fren was using jet fuel for the test. testing a jet fuel in a 2-stroke ICE doesnt prove anything sir, its not intended for the purpose. a very interesting test though
a higher octane fuel for the right application doesnt hurt any engine, its like an engine dat has been tuned fora higher ron will be destroyed in seconds when a lower ron is filled in. d lower ron wont be able to cope with the aggressive tuning for the higher ron fuel, hence produces much detonation during operation and destroying the engine
