Sori just to share some experience i encounter before.
I did have a sprint (30 lamp pole from stop ) with few of my friends' cars listed below :
1) Totoya altis (A) 1.6 '05 mod - air filter change & lighten crank pulley , rest stock
2) Hyundai getz (M) 1.6 2 door ' 06 mod - lighten clutch & flywheel , simota air intake , lighten crank pully , exhuant stright through
3) Mitsubishi lancer 1.6 (M) sport ver. '05 - Open pod air intake , piggy back ECU, exhuast stright through
4) Honda civic ES1 (M) 1.7 ' 05 mod - Open pod air intake , exhuast stright through , lighten crank pully
My car - Honda civic ES1 (A) 1.7 '05 mod - drop in stainless steel air filter , lighten crank pully , supiours 2nd intake .
Result :
My car Vs Totaya altis - we try 3 time , initial take off , altis seems to be faster but when come to 2nd gear , altis seems to drop back and by the end of the sprint i won by est. half a car length
My car vs Hyundai getz - we try 2 time , initial take off , getz pick up fast but around 3rd gear , i felt my car catching up but by the end of the sprint getz won by 3/4 car length
My car vs Lancer - we try only 1 time (due to tp coming) inital take off , both car seemsl to on par , but once into 2nd gear , lancer start to overtake and by end of the sprint lancer won by 1 car length
My car vs civic (M) - we try 1 time (i felt boring after this try) inital take off , civic seems to fly out and no matter how i try i can't catch up , by the end of the sprint civic won me by 2 to 3 car length.
The above is just a small race i did with my friends to share , not to be taken seriuorsly as only reffence many factor not inculed eg. driver factors etc ....
