jturrell Posted October 29, 2010 Share Posted October 29, 2010 It'll be several months before the car shows up (and probably a couple more months to build it), but until then I can torture myself by staring at this . . . it arrived a lot quicker than I would have expected. http://i51.photobucket.com/albums/f394/jcturrell/Quaife_Sequential_Small.jpg Link to comment Share on other sites More sharing options...
11Budlite Posted October 29, 2010 Share Posted October 29, 2010 Looks interesting! Is that a Quaife? Link to comment Share on other sites More sharing options...
jturrell Posted October 29, 2010 Author Share Posted October 29, 2010 Yup. It's the Quaife 60G. I went with the Helical version. My understanding is that the straight-cut gears may be stronger and provide better power transfer, but are really noisy. I'm not sure the extra strength or performance would mean much to me - I'm not a competitive racer or anything. The helical gears seemed like a good compromise.

jturrell Posted October 30, 2010 Author Share Posted October 30, 2010 (edited) It was a bit pricey, but not quite that bad - even with all of the ancillaries and shipping. I made a few frugal decisions in other areas that allowed me to fit it into my budget. For example - I have no weather gear or windshield. I'll be building the car myself. I'll probably purchase a low mileage duratec from a salvage yard, rather than going the $3800 dealer route. (There are 2010 duratecs out there with less than 500 miles on them for under a grand. I suppose it's a risk, but I can make two or three big mistakes and still come out ahead.) In the end, the sequential was more important than a lot of other options for me.

BrunnyS1 Posted October 30, 2010 Share Posted October 30, 2010 Yeah, very trick, I was looking on their site and saw it at 5k to 6 k GBP ,so I figured door to door with current xrates it might be @ 9k to 10k USD;does anyone else you know have one?

Off Road SHO Posted October 30, 2010 Share Posted October 30, 2010 That's a sequential box? Looks like a regular H pattern. Tom Link to comment Share on other sites More sharing options...

Ian7 Posted October 30, 2010 Share Posted October 30, 2010 ... is that the straight-cut gears may be stronger and provide better power transfer, but are really noisy.... I've got a straight-cut Quaife in my car, really not all that noisy, given the exhaust and wind noises as well :-) Link to comment Share on other sites More sharing options...
jturrell Posted October 30, 2010 Author Share Posted October 30, 2010 It's not this one: http://www.quaife.co.uk/catalogue/products/qbe26z6h but rather this one: http://www.quaife.co.uk/catalogue/products/qbe60g-0 Here's what it's going to go into: (when it arrives in a few months) Caterham R400 (narrow chassis - Caterham blue w/ white stripe and noseband) Lowered Floors Dry Sump Titan Plate-type LSD Avon ZZR's w/ 13" Wheels Track-day roll bar Battery Master Switch R500-style switchgear (Standard on UK R400's now, but an option for us in the States.) R500 Tunnel Cover (has a slot for the sequential transmission instead of a "boot") Aero Filler Battery Master Switch Stack Dash (not the race one w/ data logging - just the regular display) Quick Ratio Steering Rack I'll build most of the car myself, but will ask Jeff Sloan at British Auto (where I have purchased the kit) to build the engine. Engine internals are a bit out of my mechanical comfort zone. Can't wait to get started. The next three months are going to be agonizingly slow.

I don't know anyone with this one, but I expect it to be somewhat similar to the Quaife sequential in my old Radical. Link to comment Share on other sites More sharing options...
BrunnyS1 Posted October 31, 2010 Share Posted October 31, 2010 Do you think a sequential is practical for everyday road use>? Any pros and cons? I have never driven one myself hence the questions? By the way, is yours to be a track car? Link to comment Share on other sites More sharing options...
sdca7 Posted October 31, 2010 Share Posted October 31, 2010 If you haven't already ordered one, you may also want to order a drive shaft loop. The hoop from Caterham is a plate with a big hole in it. Link to comment Share on other sites More sharing options...
jturrell Posted October 31, 2010 Author Share Posted October 31, 2010 If you haven't already ordered one, you may also want to order a drive shaft loop. The hoop from Caterham is a plate with a big hole in it. I've heard a couple of people mention these, but can't find one on the Caterham parts site. Also, couldn't find mention of them on BlatChat or Pistonheads - but I know I've read posts about them before. I'm probably searching on the wrong term. Can anyone direct me to a specific part?

I have never driven one myself hence the questions? By the way, is yours to be a track car? I've never driven a car with a sequential transmission on a public road, so I'm not sure what it will be like. I don't know why it would be any less practical than a regular transmission - motorcycles don't seem to have any problems navigating public roads and they're all sequential. My car will be registered for road use, but I'm not sure how much time it will spend there. The lack of a windshield will likely prevent any significant road trips. (You don't need a windshield to register a car in Texas.) I'm not sure how I feel about tooling around town in a helmet. We'll see. I might end up with a windshield later on down the line. Since I won't be involved in any competitive racing, the main benefit is the fun factor. Banging through the gears with clutchless upshifts will put a very big smile on your face. All you have to do is lift off the throttle a bit. And while I wouldn't consider myself a particularly skilled driver, the sensation makes you feel like Michael Schumacher.

sdca7 Posted October 31, 2010 Share Posted October 31, 2010 (edited) Mine came with the car (R500), so I'm sure if you call Caterham USA they can order one for you.

WestTexasS2K Posted October 31, 2010 Share Posted October 31, 2010 I have been wanting one of those for awhile. I will have to keep dreaming for a little while longer. That is going to be so sweet. I would have choosen the helical over the straight cuts too. I have to admit I am a little envious. Link to comment Share on other sites More sharing options...
bsimon Posted October 31, 2010 Share Posted October 31, 2010 Do you think a sequential is practical for everyday road use>? Any pros and cons? Basically any dog box can be driven satisfactory on the street, be it a sequential on an H-pattern. The only mildly irritating part is the backlash in the dog clutches. When you get in "speed up-slow down" type traffic, you get lots of clunks an bumps as the engine takes up the slack on or off the throttle. IMHO, a pretty minor issue for a Seven type car.

Mondo Posted November 1, 2010 Share Posted November 1, 2010 Clutchless up & down shifts... This is great for bike engine 7s (paddle shifter accessory) and it looks like they're working on car sequential gearboxes. http://www.flatshifter.com/ Link to comment Share on other sites More sharing options...
