Croc Posted January 26, 2011 Author Share Posted January 26, 2011 Brilliant photo - really does look like the backroads of nowhere. Yet again this reminds me of what a huge roadtrip you achieved with your Seven - monumental achievment! Back to the discussion topic - I think you are right. Cosworth does say it will take a mix of regular octane and premium octane for short periods but the motor should be in unstressed conditions. Not something I would want to intentionally go for. Did you use an octane booster for any fill ups on your trip? Link to comment Share on other sites More sharing options...
blubarisax Posted January 26, 2011 Share Posted January 26, 2011 I thought the 256/260 hp motor was 12:1 Link to comment Share on other sites More sharing options...
Dave Posted January 26, 2011 Share Posted January 26, 2011 Fantastic looking machine. The engine is drool worthy. I love that dash as well. Link to comment Share on other sites More sharing options...

Did you use an octane booster for any fill ups on your trip? No, I did not use an octane booster, though I probably should have carried some. i didn't think i would be able to carry enough, and I was already carrying lots of spare fluids -- 5 extra gallons of gas in a custom can, and 4 quarts of oil. I meant to explain --the large brown box that looks like it's attached to my Seven in the photo, and the one on the other side of the gas pumps, are bear-proof trash receptacles -- the only kind to have in his part of the world.

Did you carry pepper spray and wear little noisy bells? http://www.usa7s.com/vb/attachment.php?attachmentid=2054&stc=1&thumb=1&d=1280589687 .

Inquiring minds :-) I would be genuinely interested to hear of altered geometry and suspension pickup points . Ok...so we should get back on track away from the question of using a Seven to outrun bears or just put noisy bells on them. The website marketing blurb says this: A bright future For over 30 years, Caterham chassis have been handmade by highly skilled craftsmen at Arch Motors, who have bronze welded the chassis tubes together and panelled the cars in their distinctive, lightweight, aluminium skin. In 2005 Caterham realised that, despite the craftsmanship of Arch, to further improve chassis tolerances and overall rigidity a new high technology construction method would be required. This also provided an opportunity to switch to all-metric dimensions for the first time! In 2006 Caterham announced a partnership with Steel Fabrications*, already responsible for manufacturing the Seven’s F.I.A. approved roll cages and road-going roll-over bars since 2002. Steel Fabrications undertook the metric based development of the Seven chassis and invested over £500,000 in sophisticated new equipment. Technology Steel Fabrications purchased both the latest CAD modelling with finite element analysis (FEA) and state of the art computer controlled tube and sheet laser cutters and robotic welding cells. These advanced processes give tighter tolerances and improved quality control, resulting in more accurate components and ultimately a better chassis. The goal of the program was a 10% increase in chassis rigidity, although final testing has confirmed a 12% gain over handmade chassis. This is a remarkable improvement for a chassis that has already been honed and developed over more than 30 years. Crash Tested As part of Caterham Cars continuing commitment to meet European type approval standards, the chassis successfully completed an extensive crash test programme that complies with Low Volume Approval. Compliance means that Caterham Cars is one of the very few low volume manufacturers that can register product in EU markets, in particular France, Germany and Italy. This crash test represents a huge achievement for a car manufacturer of its size and highlights the technical integrity of the chassis. Passing these crash test requirements will guarantee that Caterham remains ahead of the competition and any forthcoming regulations in future years. The best gets better Chassis rigidity is a key component in the handling of all cars, because chassis flex is the enemy of suspension geometry. So, all this technology means that your new Sigma engined Caterham 7 will handle, ride and fit together better than ever before! To put some more meat behind the blurb, there is this study which was originally on the Caterham UK website but now seems to have disappeared - click the "O'Connell" attachment to this linked post: http://www.usa7s.com/vb/showpost.php?p=29481&postcount=1 I know it talks about Roadsport SV however in marketing terms it became the CSR. So that is the theory and statistical element covered, now the other aspect of your question is whether there is truly a seat of the pants difference in feel? No idea - have not driven a CSR back to back with a regular de dion or other Seven for that matter. I have driven a Birkin IRS car at some length and was thoroughly impressed with it over the regular Birkin live axle on same real world crappy roads.
