Speed vs revs in each gear

Post by IanD » Mon Jun 02, 2014 10:02 pm

After our Clachtoll conversation and me saying how high geared my car is, Steve didnt think his 111s was as high so for the benefit of Campbell and Steve here are my investigations on the way home and with some extrapolation

2nd gear , would do 77
3rd gear, would do 103
4th gear , theoretically about 500revs before the cut off it would do 132
5th gear , revs at dead on 3000rpm at 70 on speedo - I checked that out

I do know 100 on the speedo is a genuine 92 from previous experience.
I also found out some route logging showed I did 260mph so my K-series actually must have done 11,500+ revs in 5th gear :lol:

This is for my 2004 111s
Noticed later on along the A890 nearer Loch Carron a guy was stopped by an unmarked dark blue volvo estate, hope you guys were ok, bet they always catch folk on that road with miles of straights, i'm always careful if i can see any car parked up or driving

Edited for accuracy 3rd June.

I would advise you to edit this and do the conversion to 'Tuts' as this is a public forum with police officers and insurance companies frequently reading these posts. The cold sea up at Clachtoll has affected your judgement. Better still, keep your findings for the next Campaganza beach conversation and edit/delete your post.

I only get to 60 Tuts in second before I moderate my speed to the road conditions and speed limits. :D

I used to have this gearbox on Egor pre-Audi. Compared to the standard S2 CR box, I loved the low revs cruising. The main issue I have with the S2 111s gearbox is the gap between 2nd and 3rd. On track it's not an issue, but on the road it leads to either bogging down in 3rd or dropping down to 2nd and revving the scunners out of the engine; it's particularly noticeable on the passes I found.

Cheers,
Robin

So, Steve - does your car have the same box as Ian's or not?!

Spot on, I actually like using 3rd gear sometimes for long periods of time on a fast road run on flowing roads as 3rd goes up and past what I need and want to do on the road but the gearing at 55-60 means being in 2nd you only have seconds of acceleration before you hit the limiter, I tend to use 3rd unless a quick overtake is really required or for corners where the exit is a reasonable steep uphill, Duke's Pass has a few corners like that.

And as per Campbell comment the whole point was to see if we have different gearbox ! Reading up it says you can check on the gearbox casing as long as the sticker is still there, mine is and it is a G6BP which is the standard s2 111s box.

The gearing on my Evora is rather tall. 70mph is about 2k revs in 6th
If I can find a very very long, very steep and straight downhill it should be good for 240mph :-)

Agreed, although I used to find my 111s frustrating coming out of the chicane at Knockhill where in 3rd it didn't feel it had the oomph to get you going again up the short straight. Left foot braking was probably the answer but still haven't mastered that.

Checked mine tonight, with the Sport box 70mph is about 2.5k revs in 6th, would I be right in saying that with Sport mode on the revs were higher for the same speed?? (Not much if they were, maybe 2-300 revs higher :? ) I didn't think to check until I was off the motorway & was struggling to keep a steady 70 in traffic.

Even better, read his 911 stuff too. Jackal is a bit of a leg end : http://www.jackals-forge.com/lotus/

I would be surprised if sport mode changed the actual ratios ... unless it has 1970s style overdrive technology :-)

Sport mode changes the throttle response, reduces the TC and stability input and increases the rev limit, it doesn't make any difference to the gearing.
Re-checked mine this morning, 70mph in 6th is showing 1800rpm.

70mph in 6th on N3 was 3800rpm. Hell of a difference, and it really needed a 7th, or a different set of ratios for a S/C car.

The new car has the UK engine and gearbox which has higher 4,5,6 so an extra 10mph in the cruise at the same revs. On the road, gear selection is 2,4,6.
