Leadership Team 700newtons Posted June 1, 2015 Leadership Team Share Posted June 1, 2015 I'm putting super unleaded in my 160 (with its Suzuki k6a engine). Any wisdom about choice of fuel appreciated... I understand that for older engines whether you use 95 or 98 doesn't make any difference. Link to comment Share on other sites More sharing options...
SM25T Posted June 1, 2015 Share Posted June 1, 2015 As it is new .. I would ask the manufacturer. Link to comment Share on other sites More sharing options...
simon_h Posted June 1, 2015 Share Posted June 1, 2015 160 is mapped for 95. No gains to be had with 98. Link to comment Share on other sites More sharing options...
CharlesElliott Posted June 1, 2015 Share Posted June 1, 2015 I've got one, works fine. Link to comment Share on other sites More sharing options...
Leadership Team 700newtons Posted June 1, 2015 Author Leadership Team Share Posted June 1, 2015 Thanks Simon. So I suppose that fancy fuel will just keep the engine clean at best.How did you know this by the way? Link to comment Share on other sites More sharing options...
simon_h Posted June 1, 2015 Share Posted June 1, 2015 Use 98 if you want for that reason but it won't give you anything on the standard engine spec. I may have been there when it was done..... Link to comment Share on other sites More sharing options...
Ian B Posted June 1, 2015 Share Posted June 1, 2015 I thought from the thread title that this was going to be about fitting a dump valve to a seven Link to comment Share on other sites More sharing options...
Leadership Team 700newtons Posted June 1, 2015 Author Leadership Team Share Posted June 1, 2015 No, that is something like the noise it makes. Link to comment Share on other sites More sharing options...
stallard68 Posted June 2, 2015 Share Posted June 2, 2015 The unmistakable noise of the 160 Its great to listen to as you go up and down the gears. I've just stuck with regular unleaded and its working a treat. Link to comment Share on other sites More sharing options...
NedK Posted June 2, 2015 Share Posted June 2, 2015 Simon_HInteresting. So, do you think there's any more capability in the engine? I've seen crazy Japanese website where they've got 100+hp from the K6A engine.And on my first test drive, the CC sales guy did mention that there was rumours of an ECU remap at some point...CheersNed Link to comment Share on other sites More sharing options...
simon_h Posted June 2, 2015 Share Posted June 2, 2015 No not really any more power to be had in the standard form and believe me we looked for it.You would need a bigger turbo and all that goes with it to get the 100hp.Have a look at this to see what lengths the Japanese have gone to for 0.5hp, i.e. nothing really.http://www.speedhunters.com/2015/06/less-is-more-caterham-160/As to what ideas CCL have for this car I dont know as we all got made redundant last year.

martyn Posted June 2, 2015 Share Posted June 2, 2015 Simon, do you know of any caterham cars that weren't mapped using standard 95? i.e. are there any cars where it is important to use the expensive stuff for best engine performance..?Cheers.

Member Jonathan Kay Posted June 2, 2015 Member Share Posted June 2, 2015 When Ratrace rebuilt my factory-ish 1800 K they recommended 98 RON.Jonathan Link to comment Share on other sites More sharing options...
NedK Posted June 2, 2015 Share Posted June 2, 2015 Thanks for the info, Simon. The Speedhunters article is interesting - not sure what I think about the new tyres. I had assumed that the car was designed around the concept of narrow tyres with high walls. Although the manifold looks rather nice, I don't think it's worth it for 1/2hp, you're right... Even in combo with the exhaust, for another 1/2hp. Probably get just as much by cleaning the airfilter!All the bestNed Link to comment Share on other sites More sharing options...
Grandmaster Flatcap Posted June 2, 2015 Share Posted June 2, 2015 I like the look af the replacment wheels though. Link to comment Share on other sites More sharing options...
rj Posted June 2, 2015 Share Posted June 2, 2015 If the engine is mapped for 95 the only "gain" from 98 is less power as it burns slower.Of course if you are unsure that the 95 at your pump is not up to spec it's safer to use 98. Link to comment Share on other sites More sharing options...
