Is VTEC accurately recreated in this game??

[KaiZen]

umm.. what didn't you get about the power/litre statement?..

if an s2000 engine was made into a V8 it would be a 4.4 litre engine with 480hp and rev out to 9000rpm without sacrificing any torque in it's rev range

Honda has always been more about handling than power, but hopefully in the next NSX they'll shove in an v8 or v10 even..

Interesting stuff about the vtec engine...

By the way... which models (and years) of cars impliment vtec (apparently there are many different types of vtec engines for Honda, DOHC and SOHC and stuff like that)

I own a Accord 96 (auto, 4dr sedan, Lx) but really never cared much to learn about it (It is my first car and after a near gta I really lost connection to it for some reason...)... When it accelerates it seems to gain sudden momentum (around 3000-3500rpm but not sure) and jerks forward... I was quite annoyed by it and just considered a fault of an old car... I also had an incident where I pushed the gas pedal a bit harder passing a yellow light... I was startled by the loud engine sound cause I've never heard that from my car before...
Anyways... I don't know if that had any relations to a Vtec cause I don't think my car has one (I rarely open the hood... I don't know jacks**t so why would I?)

I tried to look on the net for models (I know newer models have it) with the Vtec engine but sorta couldn't find one that has strong confidence for their answers... (I believe mine is just an inline 4? according to several sites... So non Vtec?)

Also after the near gta the repair guy got a used Accord 97 key slot (and the other stuff around it)... The car engine reacted a bit different for some reason... (And my car makes a weird sound when it locks... 'Brrrrr!')

BTW really nice fuel economy though... My uncle was surprised that I only use 20 bucks per week for gas... He thought atleast 30 bucks... (He owned an Accord 98 v4 and now owns and Acura MDX...)

oh, and you want power per litre.. 1.3 turbo rotory dragcar doing 7's in the quarter!

Put that in your pipe and smoke it, big blocks!

 

[KaiZen]

ANIMATERIA.. do some more research I say.. nothing better than learning more about your car. I'd say, since it's a 96 and has good fuel economy, it at least has the economy version of VTEC, so just the variable valve timing feature..

try Temple of VTEC.. i think its www.vtec.net

 

[///M-Spec]

WE'RE comparing apples with pairs now..

IT'S all about power per litre (without using a turbo that is)

an s2000 still produces the most power per litre in a natrually aspirated engine and I think the new M5 runs in at a cloes second with 500hp at 5 litres..

There is a discussion in General Automotive about Specific Output you may want to read up on.

The short version is that in the real world, it is a useless measurement. NO ONE who buys a car is concerned about specific power because there is no quantifiable benefit. Much more useful is power/weight or dollar/horsepower.

if an s2000 engine was made into a V8 it would be a 4.4 litre engine with 480hp and rev out to 9000rpm without sacrificing any torque in it's rev range

Not anywhere near as simple as it sounds. As you add mass to a moving part, the amount of energy you deal with rises at an exponential rate. The increase in internal friction and amount of reciprocating mass due to doubling the number of bearings conrods and pistons alone would no doubt require a major redesign. Any amount of strengthening would add mass to the parts and then it becomes a vicious cycle. I doubt it would spin to 9,000 RPM unless it were made of unobtanium. If they did get one to work, it would probably cost more than a whole car.

Do me a favor. Don't multi-post.

EDIT:

Um. You DO realize that any form of supercharging (of which a turbo is a form of) is conceptually the same thing as increasing displacement, right?

I believe you took that out of context. The comment was in reference to naturally aspirated engines.

I'm getting 104hp/liter straight from the factory, no forced induction needed. And it handles like a dream.

[KaiZen]

Firstly.. I do apologise for multi-posting. I get carried away sometimes

b. the M5 produces 100hp/litre@8000+rpm so Honda should be able to top that, maybe not 9000, but at least over 8000. Just takes the right materials. I DO realise people dont care about power/litre and that power/weight is more important and/or dollar/power.

this thread got abit out of hand. the topic was if VTEC is properly simulated in the game and it turned into an automotive discussion. Maybe half the thread should be moved

3. yep, any form of forced induction is to compensate for the lack of torque and engine produces.

I just dont like it when people say "this is better, or this is better". Each to their own.. it all comes down to what sound you like your engine to make.. you can always add more power! That's my opinion anyways

 

[KaiZen]

AMV8.. yeah i know, but someone brought up dragcars, so I did too


EDIT: M, I didn't mean to multi-post here.. didnt refresh after reading your post so I didn't get to read AMV8's post

maybe I should have just edit my last post to include this comment


can I delete posts?

Some people do care about power to weight ratio, like me. It takes alot of time and development to get alot of horsepower out of an engine naturally. I like the thought of driving something that was developed with alot of engineering involved. I think it's "smart" horsepower.

The 5-liter V10 M5 engine puts out 500hp @ 8,300rpms. Very similar to the Lamborghini Gallardo engine, and that's considered an exotic.

BMW ///M does amazing things with engines. They did afterall build the McLaren F1 engine.

And yes, it has gotten a bit off-topic, but who cares? We all like talking about the cars we love and drive.

 

[Ronnn]

For those people saying variable valve timing has been out for long time and many cars have it. I think they have to re-educate of what VTEC really is.

VTEC is variable Valve and CAM timing, not just valve timing like all others Nissan and Toyota. Mitsubishi Lancer MR (Mirage) uses about the same technology as Honda, but just not as good as Honda, but that Mitsubishi claimed that pump out 175hp, at that time it had higher output than Honda Civic EK4 (EK9 wasn't out at that time)

VTEC cam has 2 different cam loops for each valve. All others manufacture only have 1 lop and uses timing to stimulate the 'variable part'.

As a huge fan of Honda, I can say Honda really makes the best mass production NA cars in the world. I say mass production because Ferrari and BMW M-series both have good NA as well, but they are expensive.

VTEC is just a brand name like Coke or Nike for a technology every major player is using these days. It may have been special in 1990, when the NSX was brand new, but it is really old news 15 years later. It is especially so considering companies like BMW and Nissan had their own valve timing tech. in mainstream cars for years before Honda decided to trickle it down to Integras, Preludes and Civics. If you think VTEC is the primary reason why Honda engines are any good, you're just swallowing the line from their marketing department.

They make good engines. And in their area of expertise (small, mass production mainstream fours and V6s), they are one of the best. But being good in these areas does not make them dominant. Especially when BMW, DaimlerChrysler, Nissan and GM are making some truly exceptional stuff these days.

hmm... VTEC.... just a name but I asure you that it lives up to its name. oh yeah if you can see skylines supras and other cars are factory turbo to produce their power but a NSX is naturally aspirated VTEC and can still make just about the same numbers. Isn't that amazing. you got to give in on that. V6 with vtec, no boosting or no extra 2 cylinders, just 3.0 litre of kick butt power...

 

[TrUeNo_oF_AkInA]

Honsetly, if you're going to post like this, just don't bother. No one is restarting the import vs muscle fight again.

With $2000 I can put a 5.0 Mustang into the 11s, starting with a running junker. It'll be a total pile, but it'll do it. So keep your silly $60,000 number in your head.

relax, I'm just agreeing that honda and acuras are better off in corners not straights.

 

[TrUeNo_oF_AkInA]

So, why doesn't Honda put a V8 Vtec in the S2000?

300 hp from a 5.7L V8 is still more than 240 hp from a 2.2L I4.

you know why, the balance of an V8 in a a short little roadster is intolerable. If you pay attention to the import industry, everything is basically performance in terms of handling and fuel efficiency. plus, balance is the key.

The nsx has a 3.2 liter engine : MT 3.2 liter 290hp
AT 3.0 liter 252hp
the nsx with the automatic transmission is a 3.0 liter.

 

[draven6801]

First off why are you guys comparing two diffrent class of cars. hondas are i4's fwd and mustang's and other muscle cars are v8 rwd you would never see them in the same class at a drag race unless it was a bracket race. All this bickering is useless. you guys sound like a bunch of school girls.

That's what I always say. 👍

I think it's just that, when people see a select few number of cars with only four cylinders, but still have that capability to wipe out an eight-cylinder muscle car, people get a little too excited. But then again, who wouldn't?

 

[Red Six]

Duke is totally right.

For every one of those variable-cam "ricers", there are TEN Ford 5.0's in Mustangs driven by rednecks that would smoke the imports any day of the week. And their cars usually look ike ROLLING JUNK.
Sure, a VVTi or a VTEC may have a huge redline advantage, but think about it for a second...the Honda might make 150lb/ft of torque at 8000, but the redneck in the Mustang has 225lb/ft available to him at 2500, about one second after he floors it.

I've seen 'stangs and Camaros that leak like the cold SR-71.
And still run 10.90.

ha, and ive witnessed a street race between a 5.0 w/cobra heads and a crx with gsr motor, wanna guess what happened?!? Probobly thought the 5.0 had him huh? Quite the contrary my friend, left the 5.0 in his dust, sorry 5.0's arent that great, 1.8 liters ate 5.0 liters, funny huh!

 

[Red Six]

Because it's not. It's nothing magic. With a properly profiled cam, the engine could make power like that all the time. Fuel economy would suffer, and the idle would get lumpy. Vtec - or i-Vtec - does nothing whatsoever to increase the peak power of the engine. What is does do is make the engine more economical and streetable to drive.

wow, highly wrong, maybe you should read up a little on the vtec system, It does alot more than you claim. 👎

 

[Red Six]

vtec was created with peak output in mind, vtec life starts at 4k and doesnt end till 9k in some vehicles, thats pretty much peak if you ask me. try reading a little more on the subject at "temple of vtec". Theres nothing worse than an ignorant person trying dictate like they have a masters degree in the subject, please dont take it personally 👍

...which is pretty much all the V-tec fanboys do. Believe me, I know plenty about cars and mechanics. And as I said, I drive a V-tec car: Acura TSX.

V-tec does not maximize the horsepower of the engine. It maximizes the delivery of that power. But if you put the same engines side by side, you could get precisely the same peak horsepower out a V-tec version and one with a fixed cam. The V-tec one would just have a wider power curve, a better street drive, and probably more fuel economy. But the power peak would be identical.

like I said dont take it personal, Im hardly a vtec fanboy, dont even have vtec never did, because you "drive" a vtec equipped car means you know all about it, dont think so, ohh and yeah I dont remember saying the horsepower would be different, maybe you dont know about vtec because you cant read 0-0---, like I said try www.vtec.net then talk to me, peace

 

[Pump]

But you will not hear any changeover. VVTi-L and VVTi is very smooth. Actually you will only have noticeable different when you drive a DOHC VTEC. You will not hear any difference in VVTi, VVTi-L, Mivec....etc.

If you don't know, just don't comment please.

You're correct about VVT etc. these are merely cam phasing/timing adjustments.

You're very wrong about VVTl-i. Their is a audible change, even w/ the stock airbox, and a noticeable increase in hp at the crossover 2nd cam "lift" point. About a 30hp jump within 200rpm. Put a CAI on there and the audible difference becomes very noticeable. The kick feel is mostly in 1st and 2nd. I'd imagine that feeling to be exagerated on en Elise due to its reduced weight.

Haha thats funny. I dont see any pro imports that run non-vtec, every pro car at the race track uses a vtec motor. Skunk 2 racing owns the all motor pro import record at 9.86 e/t and guess what its vtec. And vtec does maximize horsepower, take the vtec away and the car wont be nearly as fast.

 

[Double_R]

muscle cars are rubbish and can only be drivin in america unless you are rich and can afford to waste money on fuel every 30 miles. Sum1 said a $2000 muslce care could run 11s and i raise my eyebrow at that.

Ok sorry, may be i was wrong...

But I am just telling my experience...

I drove EG9 and EK4 and also BB6, all had huge different in sound and power
But I drove Altezza, I can feel the power is going up, but no difference in engine tone, or not as noticeable than VTEC....well may be I am wrong, but I am just telling my experience

 

[Pump]

The Altezza is not equipped with VVTl-i, it has VVT-i.

VVTl-i is only found on Toyota's 2zz-ge engine, which is a 1.8l 4cyl with 180-190hp depending on application. It can be found in the Celica GT-S (and SS-II, M-sport etc.), Corolla XRS (and other Corollas not sold in the states), Matrix XRS, Pontiac Vibe GT, and the newer Toyota-powered Elise and Exige.

 

[syclone538]

I think I see where you guys are disagreeing about VVT. Does it make a STOCK car faster? Yes, because a stock car without VVT has a mild/midrange cam to compromise low rpm with high rpm, while the VVT car has an aggressive/topend cam that it doesn’t use all of the time so you don’t get the rough idle and loss of power at low rpm. Now take two cars, one with VVT and one without VVT but otherwise identical and put a cam with the same aggressive profile as the high rpm VVT cam in the car with out VVT and the cars will be very close on a track and peak power will be exactly the same. The only advantage a VVT car will have in racing would be the 60’ time in drag racing or coming out of a VERY tight corner on a road course.

I sure hope so, as I'm getting a Surround sound system for my birthday that should recreate those perfect sounds in even more detail. Apart from when I play into early hours of the morning and parents tell me to turn it down hehe
