catastrada Posted August 8, 2013 Share Posted August 8, 2013 I'm thinking moving to a sequential gearbox ( plus a flatshift solution). I know several people using the Sadev 6 but don't know anybody who is using the quite new (and cheaper) Quaife 7 speed. Would someone share his experience fitting and using this 7speedgearbox ? (My Caterham has an imperial small body with a 2.0 L Duratec producing 224hp). Link to comment Share on other sites More sharing options...
2GBR Posted August 8, 2013 Share Posted August 8, 2013 We are running a 89G (7 speeder) in a race R400 1.8 K virtually the same size as a type 9 and at 33kg is 5kg lighter than the 60G. 7th gear is 0.920. A handy box for a high reving low torque engine. We 🥰 it. AP Racing have designed and supplied a 5.5"clutch plate which we are testing which can take the down shift loads ok which will be available very soon.

Pendennis Posted August 9, 2013 Share Posted August 9, 2013 I never knew that Gerry It is quite a bit cheaper than the Sadev and with the extra gear really has to be a better option than any six speed Must admit this is probably the route I am going Gerry I will be sending you an email for a bit more Cheers Ian Edited by - Pendennis on 9 Aug 2013 16:30:52 Link to comment Share on other sites More sharing options...
catastrada Posted August 9, 2013 Author Share Posted August 9, 2013 I guess you are using a 3,62 final ratio? What tyres are you using and what is your max speed please? Link to comment Share on other sites More sharing options...
Rob Walker Posted August 10, 2013 Share Posted August 10, 2013 Never any posts about the Elite 6 speed IL200 box, its much lighter 22Kg and half the price of the Quaife at £3600. I know that the very early boxes gave trouble especially when used with the electric solenoid shifter but I have been told that the box is now sorted and really good value. Simon Rogers ran one for years perhaps he can comment. Rob Edited by - Rob Walker on 10 Aug 2013 07:38:46 Link to comment Share on other sites More sharing options...
2GBR Posted August 10, 2013 Share Posted August 10, 2013 Quoting Catastrada: I guess you are using a 3,62 final ratio? What tyres are you using and what is your max speed please? Plenty of gear calculators on line but,We change diff depending on the circuit either 3.62 or 3.91,Tyres ZZR in A60 compound 560mm, Max speed on data so far is 215 kph at Castle Combe going over the crest into Quarry with the 3.62 We are still using a stick shift, No flappy paddles as yet Not sure the 7 speeder will be any good on a big duratec though The Elite IL200 is a very cost efective way of getting into a seq, And yes there has been problems in the past. Mostly sorted now i believe. As allways you get what you pay Link to comment Share on other sites More sharing options...
Pendennis Posted August 10, 2013 Share Posted August 10, 2013 I used the Elite ILS200 6 speed in my last race Caterham, in fact it's still in there. It never missed a beat for me over 4.5 year period, but Rob they don't like heavy handed use Closer ratios will always offer more speed irrespective of engine torque, Gerry there is a few in the Mags using this with Duratec power But your right the Quaife is more than the Elite for a reason 😶🌫️ Link to comment Share on other sites More sharing options...

BSA Posted August 10, 2013 Share Posted August 10, 2013 I have been using a Elite IL200 6 speed for this season for track days mated to a 1.9 k Series with a very light sub 2kg Flywheel i had made and a 5.5' twin plate clutch from super clutch, Simon at Meteor worked out all the ratio's for me. Its a tight fit with the reverse leaver it didn't help that they supplied it with the wrong input shaft length but once that was sorted it went in ok I fitted an oil temp gauge to make sure it doesn't over heat, The transmission tunnel is open passed the hand break to help ventilation and i change the oil every other track day. pendennis recommended fitting a catch tank for the breather that was a simple job. were pleased with the results its an idea combination for a our K series engine.

Pendennis Posted August 11, 2013 Share Posted August 11, 2013 So how much is the Elite ILS200 nowadays? Link to comment Share on other sites More sharing options...
BSA Posted August 11, 2013 Share Posted August 11, 2013 I think its about £3,800 + gear position sensor + VAT if i remember correctly its a lot less than a Sadev but i could get away with one with the lower torque of the K Link to comment Share on other sites More sharing options...
Pendennis Posted August 11, 2013 Share Posted August 11, 2013 The 200 is meant to represent 200lb torque as it's working limit, as you know my 180lb Duratec didn't cause any issues. decisions, decisions, decisions Link to comment Share on other sites More sharing options...
BSA Posted August 11, 2013 Share Posted August 11, 2013 Ian as you know the Sadev is all round a much better Box its a tricky one isn't it because its a fair bit more expensive. Quaife i hear they are a not the most pleasant company to deal with Link to comment Share on other sites More sharing options...
Pendennis Posted August 11, 2013 Share Posted August 11, 2013 There will always be moans and groans about suppliers, especially on the internet So unless it's first hand experience generally I try not to take them on board Does anyone know how much oil the Quaife 7 speed takes, without wishing to hijack this thread, also the Sadev Link to comment Share on other sites More sharing options...
catastrada Posted August 11, 2013 Author Share Posted August 11, 2013 No hijack, as you know I'm very interested in all those information to make the right seq. choice for me. Link to comment Share on other sites More sharing options...
BSA Posted August 11, 2013 Share Posted August 11, 2013 Catastrada an Elite IL 200 6 speed would be ok for your Duratec if its under 200lb torque I bought mine through Simon at Meteor Motorsport who supplied the mounting bracket and worked out the ratios BUT if you have got any ideas of using it on the road forget it its a pig it was never designed for road use.

catastrada Posted August 13, 2013 Author Share Posted August 13, 2013 My Caterham is a track day car only (not registered). I'm very pleased with my ccurrect Quaife qbe15z, 5 speed, h pattern, alloy main case and cover. My Duratec does not rev very high as the max power is at 7.300 (engine built by Ammo). To adapt my max speed I'm using 2 different rear tyres depending on the track . With Michelin 22/54/13 max speed is 217 km/h at rev limiter (ok for A majority of tracks like Spa, Magny-Cours...). it´s way too short for Dijon or Hockenheim. With Michelin 24/57/13 max speed is 230 km/h (like in Dijon, but slower in Spa or equal in the best condition as the straight line is going up). Acceleration is fine with both tyres. I don't have the torque value in my head, I need to check when back home (I'm currently on holiday). (Max speed values are coming from AIM data login using the AIM GPS antenna).

elie boone Posted September 5, 2013 Share Posted September 5, 2013 The Sadev is not that more than a Quaife G60, here is the Sadev maybe there is even a small margin on the Sadev ? Edited by - elie boone on 5 Sep 2013 08:31:05 Link to comment Share on other sites More sharing options...
catastrada Posted September 5, 2013 Author Share Posted September 5, 2013 Hi Elie, I hope you are doing well Now the Quaife 7 speed is out of my list. If I go seq. I will buy a Sadev. Deicision is not taken yet. Link to comment Share on other sites More sharing options...
elie boone Posted September 5, 2013 Share Posted September 5, 2013 I am fine thank you, i have just send a PM with some pic of your old nosecone. I also need to decide wheter or not to go for the Sadev. Link to comment Share on other sites More sharing options...
Pendennis Posted September 5, 2013 Share Posted September 5, 2013 But the Sadev is comfortably a 1000 euros more than the Quaife 7 speed 😬 Catastrada, why you no like 7 speed? Link to comment Share on other sites More sharing options...
catastrada Posted September 5, 2013 Author Share Posted September 5, 2013 At today's rate, the Quaife 7 speed costs € 5.907 compared to € 6.528 for the Sadev (both exc. VAT) I'm not convinced that having 7 speed is an advantage on a 2.0L Duratec. Link to comment Share on other sites More sharing options...
Pendennis Posted September 5, 2013 Share Posted September 5, 2013 Depends who you buy it off. Today I would be paying 5320 euros 😬 If your not bothered about getting the most from your car, then the 6 speed will do, but if you are then the 7 speed will make you faster. It's simple, forget talk of torque closer gears saves you time and will make me faster Link to comment Share on other sites More sharing options...
Racing Snake Posted September 9, 2013 Share Posted September 9, 2013 The Sadev is a brilliant gearbox and well worth the extra euros. Thats probably why Caterham put it in their R600 😬 Link to comment Share on other sites More sharing options...
