why only 120

If the cars came with V or Z rated tires, then they wouldn't have the limitter. But why would the factory want to put high speed rated tires on a Civic? The most I have ever got out of mine was 124 MPH indicated and it wasn't cutting out yet. I don't think it will pull any more in top gear.

Rep Power: 0 High Octane fuel will make you un even slower.... Higher octane fuel is as exlosive as lower octane fuels... it is good for high compression engines because it will not detonate as easily with compression as low octane fuel... Butting in cheapo 86 Octane fuel will give you the most Power from our 2k1's.. Not enough compression for pre-detonation anyways.

Rep Power: 0 I disagree. The EX engine compression ratio is 9.9 to 1. That is rather high in today's engines. Just how does that engine keep from knocking on regular gas? I believe it's partly due to the computer sensing knock conditions and retarding the timing.
"Higher octane fuel is as exlosive as lower octane fuels". If this is the case then why do I need to run at least 91 octane in my LT1?

I believe he meant "Higher octane fuel is <font color=white style="background-color: 3E3E3E;">NOT</font ft> as exlosive as lower octane fuels", which I agree.
Higher octane fuel has higher resistance towards spontaneous combustion so that un-controlled burning does not happen as easily on high compression / hot running engines.
High pressure and high temperature are the main cause of pre-ignition / detonate.

Rep Power: 0 It's all a matter of engine tune and at what point you are going to get "pre-ignition knodk" (minor detonation)
Anyone with experience with the earlier emission control cars and the early unleaded gasoline will know what I am talking about.

<< why do you need to go over 120mph anyway >>
, Agree, the only thing your going to do @ that speed is kill yourself or SOMEONE else. >>
If you got some redneck in a monster 4x4 running on your back bumper and you speed up to 90 or so and can't get over on account of the right lane is full of traffic, then it's nice to be able to speed up and find a spot to get over. Besides, those 4c4's don't corner all that well at 120 so he'll probably back off. It's not that you want to go out and drive 120 all day, every day.

Rep Power: 0 I think that last statement is bs. I don't mean to tick u off or anything, because i think that is the only reason you would speed up to 120mph. If the person in the truck ticks u off so much, I would slow down and pi$$ him off. I can see maybe having a higher rev limiter (If you had more power)to get out of his way when you're merging onto a highway, but not up to 120mph cause that doesn't make sense.

Rep Power: 0 ok, i've gone 135 in my civic. there's no need to go much more than 80 to merge around traffic and such. when people creep up on your a$$, you just slow and let them get all mad. this one lady earlier wouldn't get off me, so i slowed almost to a stop. she floored it past me. i floored it as well and clicked on the high beams and followed her all the way to her exit ramp. never went faster than 100 though.

Rep Power: 0 my compression is 10.4 and I need 91+ in my Si, she has no problem doing 130+!
As for the 2k1, its not worth even going over a 100. After going past 100 it accelerates so slow to make it even worth it.

Rep Power: 0 << I've gone 121 with room to spare. Why does the manuel say to use 87 gas if your not suppose to?? And my car goes 100 kinda easily in 4th. >>
you are supposed to use 87. if you use any higher, not only are you WASTING YOUR MONEY, you are also LOWERING GAS MILEAGE
So why are people telling other people to use a higher octane. And I thought all honda top out at redline at the top gear...unless this speed limiter is something new to hondas. i have gotten my moms 96 civic dx up to like 115 but then the car gets all unstable and stuff its kinda scary.

Rep Power: 0 The only thing a higher octane gas does is burn quicker and better for more efficiency. But with our engines being ULEV, we dont need it. 91 or better octane is designed to be put in bigger vehicle with Eight cylinder and some 6 cylinder engines in them.

Rep Power: 0 Burning higher octane gas in an engine designed for regular is a waste of money and a waste of the environment. Higher octane fuel burns SLOWER on purpose, and has fewer calories/gallon (thus you may see lower gas mileage). But lower gas mileage is negligeable. You'd never really be able to quantify it in real life. Higher octane gas wastes the environment because burning the additives that increase the octane number are nastier for the environment than not burning them. They're better than lead, but they still ain't great. If the engine is designed to run on regular, it will not benefit from fuel with higher octane. Among MANY other reasons for this - If it would increase the HP rating, or gas mileage, or whatever, Honda would simply specify higher octane fuel, like they do in many Acura models. It is no sweat off their brow, nor money out of THEIR wallet to spec it.
I won't sit here and prove these facts - they are well established, and can be found all over the internet if you want research them. Don't believe all the gasoline marketing hype. Knowledge is good.

Rep Power: 0 I read an article once about gas and different octane levels...to sum it all up the difference when burning them in a normal car, no forced induction at all, is that it doesn't matter what you burn....
burning the "cheap" stuff or the high octane stuff doesn't make a difference. unless your running a turbo or super charger.
