pascoe Posted October 23, 2007 Share Posted October 23, 2007 Are the camshafts fitted to the 140 x-power k series the same as those fitted to the m g 135 engine? If not where does it get its extra 20 bhp from over the standard 1.8? CORNISHMAN NOW BACK IN CORNWALL willie pascoe Link to comment Share on other sites More sharing options...
oilyhands Posted October 23, 2007 Share Posted October 23, 2007 If you believe the extra 20BHP, the 140 cams are the 1369 profile which is the same as the VVC exhaust cam / TF135 profiles, 252 degrees, 9.3mm lift, up from 248 degrees and 8.8mm lift.Two VVC exhaust cams will do the same job, or you can get them from Piper, you could also have your stock cams reprofiled to that spec., they are pretty tame. The other changes are a VVC inlet manifold and 52mm TB. The VVC inlet manifold is not matchd to the head so there is a large step between manifold and head face.

pascoe Posted October 23, 2007 Author Share Posted October 23, 2007 Thanks for the early reply Oily I was thinking of fitting these cams together with a larger TB into a 1.4 to give me an exrta 15 BHP What do you think? willie pascoe Link to comment Share on other sites More sharing options...

oilyhands Posted October 23, 2007 Share Posted October 23, 2007 I'd go for a bit more cam than that, the BP270s or 633s are more like the SS cams Stock 1400 244 degrees, 8.2mm lift stock 1800 248 degrees, 8.8mm lift TF135 252 degrees, 9.3mm lift BP270 260 degrees, 9.6mm lift 633 264 degrees, 10mm lift Oily Link to comment Share on other sites More sharing options...
Andrew M. Posted October 23, 2007 Share Posted October 23, 2007 Question for 'Oily' I think. Which of the camshafts that you listed are the ones that PTP list as R140 part no O1LGC000280 X 2 ? Link to comment Share on other sites More sharing options...
oilyhands Posted October 23, 2007 Share Posted October 23, 2007 Like it says in the first post.. "the 140 cams are the 1369 profile which is the same as the VVC exhaust cam / TF135 profiles, 252 degrees, 9.3mm lift, up from 248 degrees and 8.8mm lift" oily Link to comment Share on other sites More sharing options...
Andrew M. Posted October 23, 2007 Share Posted October 23, 2007 Thanks Oily , that makes that clear. I wasn't sure if the part number including the number '280' indicated 'degrees'. But obviously not. Link to comment Share on other sites More sharing options...
oilyhands Posted October 23, 2007 Share Posted October 23, 2007 280 degrees would be extreme indeed on a 4 valve engine... Oily Link to comment Share on other sites More sharing options...
CAB Posted October 23, 2007 Share Posted October 23, 2007 Hi Oily How close are the SS cams to the BP270 and 633 profiles? Are the prices on your website up to date? I might be after a set of adjustable cam wheels and a new cambelt for an 1800 SS in the next few weeks. I need to take the engine out to change the clutch release bearing so this will be an ideal time to do it when it's on the bench. I might also be in the market for a K16 Caterham SS throttle body kit at some point. Is this supplied with instructions and does it work with the standard short primary 4-1 exhaust? Hello Willie/Irrotational. I'm a fellow Cornishman as well but stuck in Bristol. Willie, where do you live in Cornwall? My mothers maiden name is Pascoe....

pascoe Posted October 23, 2007 Author Share Posted October 23, 2007 Hi This seems to be turning into a lost cornishmans forum Iam now living in Trevithicks hometown -Camborne The ss cam or the similar profiles are a good choice but you rarely see any s/h for sale Thanks one and all for the information willie pascoe Link to comment Share on other sites More sharing options...
Englishmaninwales Posted October 23, 2007 Share Posted October 23, 2007 The ss cam or the similar profiles are a good choice but you rarely see any s/h for sale Put a 'wanted' post up; I got a secondhand pair of SS cams last week as result of doing just that!

oilyhands Posted October 24, 2007 Share Posted October 24, 2007 CAB, the 633 profiles are pretty close to the early SS, later SS ones are tamer. Please contact me off BBS for any information about my website / prices. Oily Link to comment Share on other sites More sharing options...
neil.cavanagh Posted October 24, 2007 Share Posted October 24, 2007 Or if you wanted to go for even more power I have ONE 285H piper cam up for grabs. Brand new in box.... Link to comment Share on other sites More sharing options...
oilyhands Posted October 24, 2007 Share Posted October 24, 2007 You'll need piper springs and probably some fettling of the follower bores for a BP285.. and to be honest you cant really run them happily on a plenum, even with an Emerald.

Englishmaninwales Posted October 24, 2007 Share Posted October 24, 2007 later SS ones are tamer. Oily, how can I tell the difference? Is there a big performance difference? Malcolm Link to comment Share on other sites More sharing options...
oilyhands Posted October 24, 2007 Share Posted October 24, 2007 The shape of the lobe if you are experienced enough, or measure the lift. The later ones are the xpower/TF135 ones... Oily Link to comment Share on other sites More sharing options...
