all i said was VTEC is way overrated, I waste ex’s that have 127hp, why? cause it’s a VTEC 127hp, do you see what I mean?
I’ve raced a few of the newer civic SI’s, they’re lighter and have 30+ horsepower, the SI is definately faster, but not alot. Not the difference I’d expect with a car that’s 200lbs lighter with a 30hp advantage.
As far as killing your low-end, when I race the only low-end I see is 1st gear, then it’s high end the whole way.
Maybe you’re right about why it VTEC was created, but if you look at what it actually does, it doesn’t make your car any faster, what it does is improves your mileage by only giving you your full power in a certain rpm range.
and I don’t understand what the tranny has to do with anything. Because Honda puts on a shorter geared tranny in their VTEC’s that makes the engine technology better or faster? That was honda’s decision, to be fair you’d have say that both engine’s type’s had identical trannies.
the only good thing about VTEC is the transmission, and valve cover. [/B]
You missed the point if you don’t see the advantage in gearing… You can put shorter gears in the transmission on the Vtec engine because you have additional rpm to work with. What do shorter gears do for you? Well, you multiply torque through gearing. What does this mean? In a nutshell, more power to the wheels. Saying that Vtec doesn’t make your car any faster is a complete and total false statement. Did you not read the part of my previous message that states that it gives you a broader powerband, more of a “flat” torque curve if you will? Remember, its not always about how much you put to the ground. While this does have an impact on a cars acceleration its also equally important how long you can sustain the power to the wheels. Wouldn’t do me much good if I made 500ftlbs of torque for 10rpms, now would it?
You are comparing your car to a Civic Ex. I already reviewed with you the idea behind the “Vtec” in the SOHC engines. Its not really there to make mad power or anything. Its there to give the car a small edge over the lower models while still maintaining a good amount of economy. Its like a balance of the two. Does this mean that ALL Vtec engines are designed with this in mind? Certainly not. You can’t compare apples to oranges, and this is exactly what you are doing.
When you say you raced the “newer” Si’s, are you talking about the 99-00 or the 2002+ Si’s? Seen as how both have completely different engines. I certainly hope you aren’t talking about the 2002+ Si’s as those are everything but lighter then your car. Please clarify as I have more for you. I just don’t want to ramble on about something unreleated to our discussion. Keep this in mind:
2002+ Si : 2744lbs
Your 90 GS: 2606lbs
1999-00 Si: 2612lbs
I don’t know where you get this “200lbs” lighter garbage. Kinda changes the whole arguement now about the Vtec engine not being “that” much quicker doesn’t it? Remember, the 99-00 Si makes a good amount less torque then the Gs does. Trust me, I know. I drive em both. The GS pulls harder then the Si (keep in mind its decently modded) but the Si would still hand the GS its ass in the 1/4 mile and anything beyond. In fact, I would say the GS would only MAYBE have a chance from 0-60 (again keep in mind the GS has a decent amount of mods on it).
