GSsoldier Posted December 28, 2004 Share Posted December 28, 2004 i was reading the generations of LS on www.lexls.com ( if u guys havent checked it out check it its freaking awesome!!!) and it seems as the gens went on the top speed decreased down from 149 - 130.... now being a speed loving teen... if i ever jump generations with LS... say a gen 3 sometime between now and my late speed loving days i want an explantion for a 19 mph decrease from top speed... does anyone know why and how they did it? and is it possible to change... i've hit 135 mph... safely i assure u... LOC doesnt condone crazy driving... it no traffic on a empty highway straight... and any speed under 120 isnt exciting... anyone help settle discomfort... why for decrease in top speed... wow what the heck did i just write ahhaha -joe nguyen Quote Link to comment Share on other sites More sharing options...
Lexus. Posted December 29, 2004 Share Posted December 29, 2004 They didn't put in the speed governor until 2001 gen 4. The gen 3 goes 157 MPH. Quote Link to comment Share on other sites More sharing options...
vcv10guy Posted December 29, 2004 Share Posted December 29, 2004 I think the reason why they changed it to 130mph versus 150mph is because the LS430 uses H rated tires as factory equipment and for a smoother ride. H rated tires are capable of a maximum of 130mph before they start to come apart, thus the reason why it needs to be limited to 130mph. H rated tires are supposed to in general ride better than V or Z rated tires and also last longer. In light of those reasons, that's probably why the LS430 dropped off in top speed for the sake of a smoother ride. Oh ya you could probably change the top speed by changing/tricking the ECU if I'm not mistaken. I remember this topic was talked about in the RX forums a few days ago. Try doing a search in that forum. Ya I added some more information after I posted. Quote Link to comment Share on other sites More sharing options...
VBdenny Posted December 29, 2004 Share Posted December 29, 2004 The government requires tires to be able to handle the top speed of the car. VCV hit the nail on the head. I guess Lexus owners would rather have tires last 50K instead of 20K and only be able to go 130 instead of 150. Frankly, I rarely go over 130 anyway.

ECUPirate Posted January 3, 2005 Share Posted January 3, 2005 I guess you don't have deer in Sacramento. The best reason I can think of not to go 130 at night is that you are outrunning your headlights, so to speak. By the time you see that deer, it's far too late. I saw a guy hit a deer at night on I-66 just outside of DC. (this is a busy ~8-10 lane highway with plenty of streetlights.) He was only going 65. I was right behind him, and I only saw the deer just before he hit it. The deer hit his windshield and shot straight up in the air like a friggin mortar. The thing damn near landed on me. The guy was lucky to have lived. At 130mph, the deer would have gone through the windshield and killed him. Quote Link to comment Share on other sites More sharing options...
