Alright guys heres the deal... this car has 189 stock hp.. so if youre realyl serious you should get a performace chip ( Could add upt to 22 hp if you buy a nice one) You should also get a new intake which will add another 15hp but you need to remember that BMWs are geard for high speeds so ur best bet is like a 50 mph roll on but even then be careful who you race. The best was to learn what you can beat is to race! I meen what have u got to lose. ( just dont bet money until u know what ur car can do) Have fun ! Drive hard...
