Message: <blockquote data-quote="meltan7" data-source="post: 3962564" data-attributes="member: 22655">Hello to my fellow zth members and sifoos. I've got a problem here related to my car's top speed.Here's my car specs:Make - Proton Wira 1.5 MMC (Auto)Mods Powerzone camshaft Adj. Fuel Regulator Adj. Cam PulleyIdirium Spark PlugsCap ayam plug cablesK&N drop-in air filter with CAI4-2-1 Powerzone extractor and piping with S flow mufflerLightened Crank PulleyThe problem is that my car has trouble going up to speed from 140km/h onwards. It could reach up to 160km/h but after a long time of flooring the accelerator pedal. On downhill, i'll be fortunate to reach 170km/h. There's loads of talk about stock cars being able to achieve top speed much easier, so i'm a bit worried bout my car's performance since i've spent so much on it, yet it can't achieve it's top speed.I've done dyno runs when i sent the car for camshaft tuning and found that it's running rich from 1000x rpm to 3000x rpm. Could there be any problems with my fuel regulator? Apart from the mods i've listed, everything else is stock.Another issue is concerning my gearbox. There is a lag of 1 to 1 1/2 sec lag between gear changes, and sometimes when the gear engages, there's a slight jerk as well. I'm sure there's something wrong with my gearbox, but i just don't know which part exactly. So, i appreciate it if any members out there are kind enough to enlighten me on this particular problem.Thanks in advance!</blockquote>
