PaulJeffries Posted October 3, 2005 Share Posted October 3, 2005 I bet this has been asked many a time! I have a 1.6 Roadsport and now have that bug that we all have - I need more power. The car pulls well upto about 80mph, then it just creeps upto 100 I know this is probabaly sue to Aerodynamics - does anyone know how to improve this - Can you put smaller lights on? Are there any easy upgrades for the 1.6, does the 52mm alloy throttle body do anything?, Cool air ducting to airfilter? Any other suggestions. Just using 95RON unleaded at the moment does 98RON improve things or is the ECU fixed and doesnt make any difference? Link to comment Share on other sites More sharing options...
Support Team Shaun_E Posted October 3, 2005 Support Team Share Posted October 3, 2005 Best way to improve aerodynamics is to remove the windscreen and fit an aeroscreen. You can buy smaller lights (try SVC for 5 3/4" headlights) but that won't make much difference. For the engine upgrade bible look at DVA Power although of course Caterham provide upgrades (Supersport - 135bhp, Supersport R - 160bhp).

Kermit the K Posted October 3, 2005 Share Posted October 3, 2005 Further to my e-mail of this morning, a Supersport kit has just come up in the For Sale section, might be worth a look. Link to comment Share on other sites More sharing options...
Mr Locust Posted October 3, 2005 Share Posted October 3, 2005 SS Ecu and cams makes a good difference. Alternatively a number of Blatchatters have used a Piper 633 cam grind and a secondhand SS Ecu as a lower cost option to achieve the same end. Basically, it fills in the missing bit from around 4000rpm-7600rpm where the standard engine goes a bit flat. Good location by the way Ian Green and Silver Roadsport 😬 Link to comment Share on other sites More sharing options...
PaulJeffries Posted October 3, 2005 Author Share Posted October 3, 2005 Hey Ian where abouts are you in Stafford, any local Seveners you know...go to any meets? Paul Chris - thanks for that will have a look... Link to comment Share on other sites More sharing options...
Bricol Posted October 3, 2005 Share Posted October 3, 2005 Alternatively - fit the 5spd axle ratio and use a 6spd box . . . at any speed up to about 100 it will just take off on flooring the throttle . . . ask any number of tailgating BMW, Porsche, Impreza, motorbikes on various motorways in France, Germany, Austria, Switzerland (and why do I have to pay a full years motorway toll to use their motorways for a day - and they don't when they come here?) and Italy. All done at 110/115 ish tho. Bri Link to comment Share on other sites More sharing options...
Mr Locust Posted October 3, 2005 Share Posted October 3, 2005 Paul, local meets at Longden nr Rugely (Mid Staffs area) and Wybunbry nr Nantwich (Ches/Staffs area). Both are pretty well attended. There are plenty of locals once you start looking. A number of us have also been known to venture into the Peak District for an early Sunday Blat+butty. If you feel the need to SS your car you will need to know whether the engine is Eu2 or Eu3. Drop me a mail off line if you want to call round. Bri, you are just a traffic light Grand Prix tart aren't you 😬 How are the blue illuminated washers doing Ian Green and Silver Roadsport 😬 Edited by - Mr Locust on 3 Oct 2005 11:07:45 Link to comment Share on other sites More sharing options...
PaulJeffries Posted October 3, 2005 Author Share Posted October 3, 2005 Ian Will it tell you in the ECU Cover? Its a 1999 Roadsport if that helps? Will try and get myself over to Rugeley sometime then, I'm in Gnosall so not to far. Paul Link to comment Share on other sites More sharing options...
Mr Locust Posted October 3, 2005 Share Posted October 3, 2005 Easiest way to spot is EU2;one big plug on the ecu and you can see the plug leads/distributor. EU3; big curved plastic cover over 2/3 of the engine top, no distributor and 2 plugs on the ECU - 1 large, 1 small. I would have thought yours would be EU2.

Alan Bowler Posted October 3, 2005 Share Posted October 3, 2005 Slight hijack... I'm currently looking at the 633 cams + verniers route (got 'em, need to fit 'em). I was very curious as to whether fitting a second hand 1.6 K (EU3) Supersport ECU would be "OK" with the 633 cams - or whether it really had to be matched with original "Supersport" cams (and so I'd have to save up for an Emerald ECU...). Are 633's and Supersports near enough the same? Also, I read stories of "friendly rover dealers" upgrading standard MEMs ECUs to a Supersport map for ~£15. Is this still true? Where?!

oilyhands Posted October 3, 2005 Share Posted October 3, 2005 It'll be fine with the 633s... Oily Link to comment Share on other sites More sharing options...
Pierre Gillet Posted October 3, 2005 Share Posted October 3, 2005 And what's the difference between the 633s and the BP 270H cams in terms of performance improvement please ? Pierre Link to comment Share on other sites More sharing options...
Area Representative Richard Price Posted October 3, 2005 Area Representative Share Posted October 3, 2005 I'll second that 633's without SS ECU are good, but better with SS ECU. Link to comment Share on other sites More sharing options...
Area Representative Richard Price Posted October 3, 2005 Area Representative Share Posted October 3, 2005 Paul, This wouldn't be a bad way to go here, and I'm sure Ian (Mr Locust) would help you fit it! Link to comment Share on other sites More sharing options...
oilyhands Posted October 3, 2005 Share Posted October 3, 2005 270s vs 633s is probably around 4-5BHP depending on the remaining spec. 270s give a marginally better idle and progression. Oily Link to comment Share on other sites More sharing options...

Mr Locust Posted October 3, 2005 Share Posted October 3, 2005 Good pics from Harewood Richard. Pictures 23-28 are more discrete than the Aintree "off" ones as you are disappearing from view but the shower of stones give it away. 😬 Paul if your car is EU2 Shaun's kit sounds ideal Ian Green and Silver Roadsport 😬 Link to comment Share on other sites More sharing options...
Support Team Shaun_E Posted October 3, 2005 Support Team Share Posted October 3, 2005 One of Paul's questions to me was is it a head off job to replace the cams and I realise I don't know the answer. Obviously I have the head off but is this necessary to swap cams? Yellow SL #32 Link to comment Share on other sites More sharing options...
Mr Locust Posted October 3, 2005 Share Posted October 3, 2005 No. Just remove the cam ladder. Took me a couple of hours on Oily's drive having never even looked at the job before. Probably a good idea to get new cam seals and definitely need a squirt of the Loctite anaerobic sealant stuff to reassemble.

Support Team Shaun_E Posted October 3, 2005 Support Team Share Posted October 3, 2005 Cheers Ian. New cam seals are definitely required as mine were leaking a bit. Yellow SL #32 Link to comment Share on other sites More sharing options...
Bricol Posted October 3, 2005 Share Posted October 3, 2005 "traffic light tart" - nah! Stevio hairpin big-bike upsetter - yes! You can out-corner them and initially get the drop - and then the braking zone for a bike is too early for the next hairpin for them to be able to stay with you, never mind get past - after a few of them you are whole straight bits in-front (apart from the loony on the super-moto . . .). And there is something about sliding the rear around those bends, tyres howling . . . Of course, as soon as you catch the next coach / Honda Goldwing (seem to take up about the same amount of road when you try to get past) they are straight past as they fit through the gap. I will get round sometime to fitting my performance bits . . . maybe . . Bri Link to comment Share on other sites More sharing options...
