Vtec?
why hasnt anything about VTEC or a similar system been posted here before?

would be pretty cool to have at least one of the cars in the game with something like that wouldnt it?
i mean, the sound and the realism would be cool, but then you could argue; why not just put in longer duration cams in the first place to make more power throughout the range rather than after 5500?

would be nice for honda fans though...

*dons flameproof suit*
it .. has been posted before

vtec? What is it? I heard of it a 100 times

VTEC
---variable valve timing and electronic lift control---

basically, the camshaft has 2 sets of lobes. one is standard and the other one is aggressive. when driving normally (town driving perhaps), the aggressive camshaft does not come into play, when the engine gets up to a certain rpm (5500 rpm for instance), the little computer thingamajig tells the vtec solenoid to engage, which forces a little pin to lock the 2 sets of lobes together using hydraulic pressure. due to the aggressive lobes having a higher profile, it overrides the less aggressive lobes, which therefore gives it a greater lift and duration and lets in more air and fuel.
in effect, you have 2 camshafts in one, which is good for economy and also sports if you may.

for example, you have a 1.6 litre VTEC engine. it puts out around 160 bhp.
this is means you have more power than most 2 litre engines whilst keeping the economy of a 1.6 when VTEC is not engaged.

*may sound a bit baffling but makes perfect sense while im typing*

i would put a gif up or something but i dont have one.

if anyone else would like to contribute or elaborate then please do. we must teach these noobs. knowlege is power...
It's a system devised to allow 'sporty' granny cars to pass emissions and noise regulations. It works by varying the cam timing or profile, usually above a certain rpm, so that a high economy/low noise setting is used a shopping speeds, and a louder, more aggressive profile/timing is used at throttle openings larger than most grannies will consider. However, it's almost exclusively for front wheel driven cars, which are, by definition, granny cars.

lol thats true...

but good luck buying a cheap rwd car these days that hasnt been to the moon and back.
if only honda or toyota made a nice 1.6-2 litre rwd car again that cost £15k tops.

there is the mx5, but thats old hat now. we need new blood. new cars. i guarantee that if a new sporty-ish rwd car could be bought for £15k or less (ignoring bmw 1 series and mazda mx5), then manufacturers would see a big increase in profit and a lot of sales. anyone with half a brain and a passion for driving would want one.

RWD
Been to the moon and back and probably can go to the moon and back again.
1.6 litre twin cam
Pick up a tidy one for £2000

thnx for explaining A M R.
Shopping trolley racing was fun yes, but only because I pwned your ass!

And I do have an MX-5. Twas cheap (ish), is brilliant to drive, and means I don't get picked for the Friday Night Driving run to the pubs and back From what I've heard the BMW 1, whilst it's a nice car for what it's trying to do, is overweight, over priced and (like all BMW's of the last 15 years) butt ugly. Plus no one will ever like you again, or be nice to you on the road

The only thing I'd want for less than £15k would be a mid engined car. but the MG TF is poo, the MR2 is so underpowered a UF1000 would beat it, and the Cappuchino is left hand drive only. LHD isn't the problem (I drive both regularly) but it doesn't half make overtaking difficult in the UK, and I don't have a lot of patience for sitting behind people at 40mph in a 60. I'd rather to 80. If they made an mid engined MX-5 type car then I'd start saving the pennies. Until then I'll cope with the odd blast in a Stratos. Is the new MX-5 (the Mk3) actually any good. I've only read one article about it, and it's handling was slated, which is odd I thought. Was it a one off, or have Mazda lost the plot?
Surely you can now pick up Mk1 Elises for under £15k and maybe VX220s (actually a better car IMO).

An old MR2 is just what you want really for todays roads fast enough to be pushed without worrying to much about the Piggy Bank Partnership vans. With such a short wheel base they handle beautifully to at road speeds (although they're unstable on fast tracks).
Quote from tristancliffe :and the Cappuchino is left hand drive only.

uh huh ? isnt the cappuchino a car that exclusively sold in japan so the real problem is its only available as rhd ?
Cappuccinnos are RHD only but Tristan come on I know they're mid-engined RWD but really would you be seen dead in one?
lol cupuccino. yeh i thought they were rhd as well. hmmm...
but arent they only 600cc? i heard they had turbos though? my mates cinquecento is 900cc and it has like 35 horses or sumthin like that, but the way he drives it makes it feel like a 1.2 hehe.

anyways. i meant a NEW car. woo if toyota brought back the AE86 somehow or even sorted out the mr2, then maybe something could happen...

hmm. why did they stop making mr2 turbo or twin tubo? we need turbo!

theres no real drivers cars anymore. maybe mx5, but thats about it. ah yeh, the new mx5, apparently its still pretty good, if not better than the old one. dunno where you read that review from, but top gear seemed to think it was pretty good, as did the driving section from the sunday times.

why the hate on FWD cars

Although it isnt seen much in racing i think Vtec and other Varible valve timming and varible cam timming could be usefull if you used it wisely


you guys looking at cars Honda S2000 is where its at Very nice driving car
:doh:

I didn't mean the cappuchino, I meant the, emm, what is it. Italian. I forget. I looked at a few when I was buying the Mazda. God my brains dried up. Little thing, nice to look at. The Barchetta, thats the one! Sorry
All fwds are granny cars. Ok. Try driving a Saxo VTS or 106 Rallye (or some other similar fwd) with hard suspension and stiff ARBs fast and well see what you think then. The Barchetta is FWD too btw.

As for the vtec its not made for emission control. Actually there are 3 kinds of vtec (e-vtec and sth like that). The two of them are to combine economy and some performance and the top vtec exists because if they just made a 1.6 160 hp engine with long duration high lift cams and not the vtec cams, it would be dead below 5000rpm (or in the low-mid range anyways) and unusable in traffic. The vtec cams make the car able to move with not much difficulty even at low rpms.
screw them stupid gay french cars. all you ever see is chavs driving them crappy saxo thingies. B16 civic eg/ek would kill them anyday.

Quote from A M R :screw them stupid gay french cars

know what you mean, i came home today, there was a saxo parked accross the street, on closer inspection i realised it was parked on top of a Megane, and it was engaged in a rather dirty act
Barchetta is FWD? *throws list in bin*

Driven lots of FWD cars, and none of them excited me. I had a Pug 205 (though it was a diesel, but that just meant a year to get up to speed), and I've driven a 106 Rallye a 306 GTi-6 and a Saxo VTR. All of them are purely designed to be shopping trolleys, with slightly bigger engines. They're still pants. I've never enjoyed driving any front wheel drive car that much. Oohh, understeer on the power. Oohh, lift off oversteer. Oohh, I've fallen asleep. RWD is the only way to propel a car in any interesting fashion.

Of course FWD has it's place. I fully imagine that when I start a family (God forbid) I'll be forced to get something dull, and the missus will obviously have to have a FWD car. But until the day I'm forced by situation to buy one, I'm RWD only. And none of this pansy 4WD for me either (unless I'm towing a racing car somewhere).

the turbo in em are smaller than a fist.. soo tiny and soo cute for a turbo.. :P

jup and the engine is up front too
I know there probably isn't alot in the UK, I know I have only seen a few, and those were from people that were american that were stationed overseas but the Dodge SRT-4 is a very good FWD. The torque curve is amazing. I have an ACR and the way the car will carve and pull out of corners I am guessing that the car is in the miata range on the skidpad( have not seen any numbers yet for the ACR, stock is .88). I walked off the lot paying around 25k. I couldn't have walked away with anything that will match it for at least another 10k on top if I went looking for RWD or AWD. This is anything but a granny car. 230HP 250 Pounds of torque that will stay there for at least 2 grand. I can post the power curve if anyone is interested. I get 30 MPG cruising down the highway. or 7.8 liters for every 100 miles. Another thing Dodge added to the car is a limited slip differential.

Performance: 0-60 in 5.6 seconds
60-0 in 110 feet
1/4 mile in 13.8 seconds

My cousin has a 99 Z28 Camaro, I walk away from it in any type of corner situation and the strait line performance is exactly the same. Same performance as a carrerra 4 too if I remember right. For alot less money.


This all being said your just asking for a car that has no low end power and has everything loaded up on the last 3 grand, and is FWD? try driving the UFR =P
next time in ENGLISH please. not AMERICAN.
I lived in the UK for 3 years. Looked like perfect english to me, if you don't know the numbers convert them there are plenty of converters on the net.

I will convert the HP for you,

230 HP = 171 KW
250 lbf·ft = 338.57 NM
