If you want to invest in a Gameshark to get speeds that are crazy and stay on the ground you can. Its called the Hybrid Theory. You can even add a 7th gear all sorts of fun things. I have gotten cars up to 680 without doing anything but throttle using hybrid theory. You can also unlock that lamborghini that you see in the vid, as well as some other nifty cars.
The trick is possible through gliches in the physics system, you guys have no doubt gotten air (not deliberately) in your cars before right? What happens you get a boost in speed because the physics engine is like WTF!! and you fly back down skidding all over the place, and or you pull a 400000 degree flat spin all while still maintaining 200+ mph. Many FPS games have problems like this.
My personal fav for the hybrids is the FTO with 10000 hp that corners at 438 mph
and God knows what is the top speed. In the 2nd one there is a dodge intrepid funny car that has 5000 horse and is just a beast
The Escudo is obsolete in GT3 as they no longer have the Pikes Peak Uphill and Downhill from the 2nd one. The escudo imho should not be able to be modified, it has two race breed vitara engines in it and is already tuned out the wazoo. Also if you guys want to score a cool billion the easy way get a fliptop ps2 cover and buy GT3 Concept 2001 Tokyo auto show. If you get done with the game you are given access to a GT3 A-spec save with a billion.
What I want to know is what the hell happened to the killer 3000 gt with the 7 speed tranny from the first two!!?? And why the hell can you only perform displacement on 1 or 2 cars!!?? And when you do it does precisely nada just about.
