Croc Posted January 22, 2011 Share Posted January 22, 2011 Here are some photos of my part way built CSR Superlight. I am fascinated by the differences in the suspension to my current SV - really neat evolution of the design. http://i15.photobucket.com/albums/a354/mjohnson555/seats/CSR/DSC00618_edited-1.jpg http://i15.photobucket.com/albums/a354/mjohnson555/seats/CSR/DSC00619_edited-1.jpg http://i15.photobucket.com/albums/a354/mjohnson555/seats/CSR/DSC00620_edited-1.jpg http://i15.photobucket.com/albums/a354/mjohnson555/seats/CSR/DSC00621_edited-1.jpg Link to comment Share on other sites More sharing options...

Croc Posted January 23, 2011 Author Share Posted January 23, 2011 (edited) So I do not forget this and I save it somewhere, the final spec settled on: CSR Superlight kit Cosworth Duratec CSR 260 engine package. This takes the standard 2.3L Duratec and (as I have it listed from Cosworth) uprates for the following Cosworth parts: forged pistons with CR at 12:1, piston rings, forged connecting rod, billet crankshaft, level 2 race camshaft, cam friction washers, race valve springs, cosworth polished cylinder head, high flow fuel injectors, high capacity fuel rail, modine oil cooler, high flow oil pump, stage 2 dry sump, roller barrel throttle bodies, carbon airbox with foam filter, new ECU with Caterham specific map, carbon coil cover, lightweight alternator (40 amp) [*]Caterham 6 spd transmission [*]limited slip differential (3.62:1) [*]inboard front suspension [*]independent rear suspension [*]ventilated front discs and 4 pot calipers [*]15" Caterham motorsport wheels and Avon CR500 tires - 6.5" front and 9" rear [*]Quick ratio steering rack [*]Carbon front cycle wings [*]Carbon rear wings [*]Aero cross section front wishbones [*]Integrated ("curvy") dash (comes with lowered floors, momo wheel and push button start). It also comes with column pod for self-cancelling indicators, wipers and headlights. [*]5 point harnesses [*]Track day roll bar [*]Paint is Titanium silver with Platinum silver stripe and noseband [*]Black pack (headlights, windscreen, carbon-look sills) [*]Brackets for quick change over of windscreen to aeroscreen [*]Spa carbon mirrors with convex lens [*]Carbon indicator pods (with clear lens) [*]Battery master switch [*]Leather seats (I was unfortunately not comfortable in the alacantara carbon tillets - pity as they were superb to look at and drool over) [*]Heater (I know - its not superlight...but it does get cold in my part of the USA) [*]Aero filler cap [*]"7" grille with mesh grille [*]Cool touch exhaust muffler [*]Tonneau [*]weather kit (sidescreens, hood, hood sticks) [*]SBFS half hood with double easy entry in [*]Aces change up lights - will be mounted on the underside of the scuttle above the tach/speedo [*]secret sauce kit good for an extra 10 hp There are other miscellaneous things that I am adding now - 12 volt plug, fire extinguisher, half doors, Hella horns, wind deflectors, high level rear brake light, sump guard, door pockets,mirrorsforsevens wink mirror, etc. To protect the carbon it is being clear coated front and back and will also be 3M clear bra'ed front and rear wings plus nose. For the aeroscreen, I am yet to make a final decision but this one is calling my name right now as it can be configured with the quick change brackets to be a 10 min conversion job: http://www.fluke-motorsport.co.uk/carbon-fibre-contoured-lip-aeroscreen-suitable-for-caterhams-p-30.html Edited January 24, 2011 by Croc Link to comment Share on other sites More sharing options...
Kitcat Posted January 23, 2011 Share Posted January 23, 2011 (edited) If there is an option you missed, I can't think of it:)! It will be quite the se7en. I am looking forward to more build pix! Mike M Edited January 23, 2011 by Kitcat Link to comment Share on other sites More sharing options...
blubarisax Posted January 23, 2011 Share Posted January 23, 2011 Mike, What about a carbon fiber diffuser and rear wing from the new SP/300.R? Great specs! Link to comment Share on other sites More sharing options...
yellowss7 Posted January 23, 2011 Share Posted January 23, 2011 Mike, No sequential? How about a video/datalogging set up for your trackday forays? What's the anticipated delivery date? Tom Link to comment Share on other sites More sharing options...
Croc Posted January 24, 2011 Author Share Posted January 24, 2011 :smilielol5: No diffuser needed - I think they look silly on a Seven because they have to hang so far off the back it looks like you have a crop harvester. Rear wing? I suppose I can use it as a drinks stand in between sessions at the June track day? Sequential - I did give this one some thought. Having driven one on track before I thought it was :drool: then I took it out into traffic. I also got very confused as to which gear I was in. So I am safer in a convention "H" pattern gearbox. Is there an option I missed? I doubt it....I did spend a wet Sunday afternoon and evening in London while there on business last year prowling the Caterham parts website catalog, Fluke Motorsports, Cosworth, Demon Tweeks and Carbon Bits for ideas that I could order for this car. And video/datalogging? Gee just great! Why not buy something that will memorialize my spin on a track day or more likely getting pulled over for speeding on a Lotus club drive...

Sean Posted January 24, 2011 Share Posted January 24, 2011 Looks great! One thing, though... if I am reading the Cosworth catalog correctly, the CSR260 engine does not have the billet crankshaft as standard, but it is available as an option. Or did you specify it on the order? Secret sauce for 10 hp? What is that - a small nitrous bottle with undersized plumbing? Link to comment Share on other sites More sharing options...

I was confused about the crankshaft initially based on the same catalog I thiink you are looking at. However Caterham UK sent me something that said it was in the spec. Short of opening up the engine I have to trust that. Secret sauce? Mmmmm.....if I tell you then it would not be secret! Link to comment Share on other sites More sharing options...
blubarisax Posted January 24, 2011 Share Posted January 24, 2011 (edited) Mike, When I was takling with Cosworth UK about the 2.3L Duratec motors, they told me that the 280 HP spec engine they normally recommended for Caterhams did not require the billet crank. Under 7,800 the stock crank is supposed to be just fine. The Cosworth 250 HP motor has 12:1 CR, 280 HP has 13:1 CR and the 295/300 HP (formula atlantic) has 14:1 and the billet crank. Cosworth UK said the billet crank was overkill other than for all out racing, but Cosworth USA seemed to like it in any application. (I'm sure at $3,500 it helps meeting sales targets!) I'd be curious to know what Caterham does to get from 250 to 260. I know that the air throttle bodies are caterham not cosworth and I bet the rest is ECU programming. If they do include the billet crank in the Caterham/Cosworth 260 that would explain a few more RPM and HP and make the motor a real bargian. I chickened out in going with the 14:1 CR and detuned my motor to 13:1 CR. The higher CR motor definately requires race gas all the time and the MBE ECU does not retard timing to prevent detonation. I definately do not want the motor go go BOOM! Nitrous, why didn't I think of that... Edited January 24, 2011 by blubarisax Link to comment Share on other sites More sharing options...

If they do include the billet crank in the Caterham/Cosworth 260 that would explain a few more RPM and HP and make the motor a real bargian. Yep that stacks up with what I was told. The standard package does not include it but it is an available option that a lot of people elect to go with but probably is not necessary other than for meeting sales targets. The roller throttle bodies that I saw match the looks of the Cosworth catalog. I bet Caterham buys them slightly down spec'ed from Cosworth and rebrand them. Caterham is not in the business of making throttle bodies but clearly someone else is and I doubt they copy a Cosworth looking design without Cosworth having a hand in it somewhere. Interestingly the Caterham UK email I have does state them as Cosworth. To get from 250 to 260? Probably exaggeration. Most of the advertised engine specs from Caterham have always been slightly optimistic. If there is any real gain then it is in the ECU software programming.
