OMFG this is the Funniest threads ever. sandblasting sand in the engine thats gold, why dont u put sugar in ur fuel tank it gives it more octane, makes ur car run more rich so u can booost more LoL.
if u really want more HP drain ur oil and just use 4L of diesel gives it more of a spark
and to make ur car run more smooth add about 1-2L of oil in ur water to give the engine more lube..
tell me how it goes after that.....
