Thanks bros, I got checked my car speed on petrol i got 110-120Km/h and i hope it can go beyound this but due to trafic i have to reduce speed.
Other things I am not such expert as you people but sure car engine and clutch plates are not weak, replaced clutch presure plates few month back.
Please help me what i need to check or what should ask mechanic to check, but if i asked mechanic to check what he can do you people better know.
