Has anyone driven a car with sequential box around town for any length of time?

I'm wondering how it might be as a (dry) daily driver.

I did use a BEC Westfield for a while some years back but not long enough to get used to it.

I imagine stop start traffic would be a nightmare. Arent they designed for flat chat upshifts ?

There is a lot of 'clunking' and, depending on the box, lots of whining from the straight cut gears. Quaife do a Helical geared 60G which I have in the Phoenix and it is doable on the roads....

Having been in a few (although admittedly not driving one), I think you could get use to the driving characteristics of it. The big issue to me is the noise...... the 620 is slightly quieter but the early boxes are incredibly loud and would make a daily drive (even with ear protection) incredibly tedious

Sadev with Geartronics padleshift and K20 Honda, I never fitted the gear lever,I live in London get traffic every time I go out I never have a shifting issue, the box is not noisy, the engine is on Jenveys with a BTB exh it's loud!!!. I would say the only (issue) is that if you have to get reverse quick because of the interlock system with only having paddles the process is somewhat slower than with a gear lever, mainly an issue when a large vehicle in front decides they have a change of plan and wack into reverse and don't even see a low 7 behind, being a biker too I always keep to one side and always make sure I stay well back

My experience so far is that it's not too bad, but does require a little more forward thinking. You don't want caught too far up the box when you are stationary.

If you have the Geartronics paddle shift it will shift as quick as you need, at first I suffered from too much (push) on down shifts with light throttle or on the over run, but set up now is perfect there is an anti push stratergy in the GCU, you get to know when using the clutch is needed, like rolling down hill to a set of lights at red and you think you are going to have to stop, you get a few raised eye brows as it blips the throttle every down shift.To begin with I used Honda/Hondata management and the off idle part throttle fueling was horrid, just struggled to get the Jenveys to work, switched to another make and it transformed the car and how it drove, WOT no issues, the Kings road!!! arrrr

The main difference is that you have to change down through the gears as you slow to a stop to prevent an embarrassing 10 seconds of repeatedly lifting the clutch slightly to align the dogs to get down from 6th to 1st when the car is at a standstill.

If you've made the most of the sequential box with a lightweight flywheel and plate clutch then you will need a bit more finesse to prevent stalling when pulling away.

A straight cut dog box will always be noisier but isn't that part of the fun?

It's no big deal, just like a motor bike but nobody says thats an issue with them, you do get used to it. I run a gearbox oil cooler and filter, I drained the oil last weekend and checked the filter..... nothing like new having done 2500 miles and 4 track days

I have the standard GSXR1000 sequential box. And a big gear display !

Really not as bad as people make out. Clutch is sortable. The real issue isn't the box or clutch, it is the delicacy of the throttle response. But once you remember to gently dial in 2000rpm you are fine. Doing it like you do in a "normal" car is when it stalls as you end up with far too many revs.

More of a nuisance than in my little Skoda with hill start assist ? Yes.

Much more of a nuisance than a crossflow without an accessible handbrake ? Not at all. In fact somewhat easier as the start button is a millimeter away and any restart is instant .... a hot Crossflow was never thus smile

Hi I could be wrong but I suspect he thinks the GSX1000 lump is in a 7, I'm not sure it is and poster is just commenting on the bike launch

It is in a 7 smile

As I said, clutch/box isn't the problem (for me, YMMV wildly) it is the throttle control.

Yep but seems he is happy with it. As far as I am aware the clutch is used in a regular dog box when pulling away so a hill start should present no additional problems.

Not the same but comparable - I've a Fisher Fury with a 'dog sequential box (R1 powertrain) and while not exactly smooth compared with the average family hatch, it is by no means impossible around town.

The slight (wet multiplate) clutch drag leads to clunks, straight-cut gears lend a certain whine, but even if you get caught in upper gears at a stop it's easy to shuffle clutch bite vs paddles to get back to the (only) neutral. Even without reverse I've not got stuck in traffic in the 5years running it.

I've had a go with a Caterham +Sadev, it's easier! Don't be afraid.
