Exx Posted December 28, 2020 Report Share Posted December 28, 2020 Hi, Do you know the labour cost/hours of work to change the ratio ? What about the gain ? Does someone know if there is really a gain in performance ? Quote Link to comment Share on other sites More sharing options...

Exx Posted January 7, 2021 Author Report Share Posted January 7, 2021 Yes i know that link 😅 i would like to know feelings of those who have done it, i ve already seen people here who seemed enthusiasts about it Quote Link to comment Share on other sites More sharing options...
Gold FFM Barrykearley Posted January 7, 2021 Gold FFM Report Share Posted January 7, 2021 Here’s a thing. Once someone’s spanked £2k doing something to their car - it’s highly unlikely they will admit it’s pointless. changing an Evora to CR - is though. Unless you are competing properly - it’s utterly pointless. Quote Only here once Link to comment Share on other sites More sharing options...
Gold FFM C8RKH Posted January 7, 2021 Gold FFM Report Share Posted January 7, 2021 In my humble opinion total waste of £2,000. If you are having to change your clutch anyway then the extra cost of this would be fine. But to open the gearbox for this. Sheer madness. I believe you'd get better performance gains from 2bular headers and removal of the 2 pre-cats for around the same price. Added benefit of taking a lot of heat away from the engine block too. 2 Quote Alcohol. Sex. Tobacco. Drugs. Chocolate. Meh! NOTHING in this world is as addictive as an Evora +0. It's not for babies!

Wilbert Camshaft Posted January 10, 2021 Report Share Posted January 10, 2021 In my first Exige Sport 350 I pondered between the "Close Ratio" and the "EX460- Kit" - given that I had bad experience with modifications at the exhaust line with a Porsche I previously owned I decided for the "Close ratio" option. Downside: apart from the expense there is noticiable increased gearbox noise Benefit: sunstantially better torque and speedup, car feels much stronger and agile, not only in 5. und 6. gear. BTW: the gear range from my perspective is not perfect for track use (3. gear - 146km (154), 4. gear - 187km (202) Here you can see the (limited) advantage compared to an equally powered Exige without "Close ratio" gearbox https://www.youtube.com/watch?v=qTQOiaBEjlQ Conclusion: In my new Lotus Exige Sport 350 I decided for the EX460 Kit and against the Close ratio - without power upgrade I would have installed the "Close ratio" again.

Mattmahope Posted January 11, 2021 Report Share Posted January 11, 2021 I am considering going for the close ratios in mine when I do my engine build. The engine (and hence also the gearbox) will be out of the car anyway, and I will probably have to open the gearbox for some strengthening work as I am already right at the gearbox limit with 500hp. I am in two minds about changing the ratios. On the one hand, the car has loads of torque and so rips through the standard gears as it is. I also quite like the longer 6th gear for motorway cruising. But on the other hand the standard gears are long so I find myself rarely dropping below 3rd on track or above 4th. I didn’t even get to the top of 5th gear at 150+ mph by the end of the Kemmel Straight at Spa. Daniel at KT seems to really recommend the closer ratios and I know @Wilbert Camshaft also recommended this approach. But it’s a lot of money for what might be minimal gain, especially given the amount of power I will have. Definitely don’t want it to feel like sprint gearing!
