s2000 motorway cruising out of VTEC zone

[mat59]

Hi guys.

Can anyone tell me at what speed the '99-'02 s2000 goes into the VTEC zone whilst cruising on the motorway in top gear?

I'm thinking of buying one but want to be able to cruise at 80 without drinking fuel.

Thanks,

Matt

I cant off the top of my head, but i'd guess that 80 is about 5k rpm.

When you start getting north of 90 its in VTEC.

Pretty quick from 100 - 140 though, so i've been told.

I think it's gear limited to 170mph @ 9,000 rpm

So assuming VTEC is at 6,000 rpm, that = 113mph.

But I can't remember in reality. I've not got up to those speeds in ages, and my VTEC kicks in at 4500 rpm.

I'm pretty sure you'd be able to cruise at 100 in 6th gear on the motorway without being in Vtec.

I'm pretty sure its less than that Bibbs. I'll try to look remember next time im on a private test track.

Surely VTEC engagement is based on throttle position and not just RPM?

Nope, dont think so. Im pretty sure it just engages based on RPM.

Thats surprising, I'd have thought the new i-VTEC was more advanced than that.

the s2000 is vtec though, not i-vtec.

I'm not even sure i-VTEC does that.

A-VTEC, if/when it appears, will do though.


S2000 is geared at, from memory, 17.9mph/1000rpm in 6th, so 89.5mph (indicated 93/94) is 5,000rpm. So the 6,000rpm cut-over will come in at around 107mph actual, which will be about 113 indicated...so Bibbs is pretty-much spot-on.

Short answer is it's loud but not stupidly loud, and unless you cruise at about 90, you'll see 28-30mpg on M-way trips.

This muight seem rude, but why do people buy sports cars AND worry about fuel economy? You want a 2l 240BHP car to be frugal? At least there is a credit crunch which is driving down fuel costs

Most people don't, but:-
a) It's nice to know that it won't empty your pocket THAT quickly;
b) With a small fuel tank (55l) it gives an idea of effective range;
c) If you're doing e.g. 12,000miles a year, the difference between 30mpg and 24mpg is ~£500 a year. And EVERYONE works to a budget of some kind or another...

115 MPH

OK. If you are going to use the sports car on longer journeys as well as for fun then it is an issue.

You'll be fine at 80mph in top gear, it's pretty economical there.

I sat in 6th and in VTEC in Germany, cruising at 120, and emptied the tank in less than 2 hours, which was a bit of a shock!

[Welshbeef]

2hrs @120mph and empty tank Im guessing not dry so maybe 5ltr remaining - that would equate to 22mpg, thats really not bad for that speed.

Can anyone here - confirm how reliable the engine is? Is it as mythical as the press leads you believe? What sort of milage can it do before a full rebuild is required & at what milage is the timing chain changed?

Check s2ki.co.uk to be sure.

The only UK failures I'm aware of have been due to oil starvation, and there are a number of guys on s2ki in the UK running cars WELL over 100,000 without anything other than routine servicing.

Given the specific output (equal to or better than most Ferraris), it's astoundingly reliable.

No that's true I suppose, I just wasn't used to having to fill up every 2 hours! Fortunately not dry, no, but was doing 56mph for a while to make sure I got to the station.

Well I'm 6 years and 44k into mine and it's totally faultless and friends of mine have never had any issues, so seems pretty bulletproof. Never heard of anyone I know needing a rebuild or anything.
