CHRIS CLARK Posted March 15, 2001 Share Posted March 15, 2001 Not at that stage yet (I wish !) but what is the suggested type for Dissy operation VVC ? Link to comment Share on other sites More sharing options...
Paul Ranson Posted March 15, 2001 Share Posted March 15, 2001 I'm not sure what level of mods you're talking about, but a starting point may be Champion RC6YCC which are available everywhere. I think these may be OE for the VHPD. Paul Edited by - Paul Ranson on 15 Mar 2001 19:49:34 Link to comment Share on other sites More sharing options...
tbhall777 Posted March 15, 2001 Share Posted March 15, 2001 Does anybody know the correct NGK equivelent to the Champion RC6YCC. Link to comment Share on other sites More sharing options...
Bob Corb Posted March 16, 2001 Share Posted March 16, 2001 Come on Chris! We're not talking 143BHP std spec VVC. You will be slap bang in VHPD territory when you've finished. The std champion plugs are well suited to the std spec tune with very little pre ignition (caused by the plug glowing red hod) at max power speeds. But it wouldn't hurt to run a grade colder. All that can go wrong is you may get a bit of fouling at prolonged idle (which won't happen, especially after what Warren sid about your cams). Its better to be safe than sorry.

Bob Corb Posted March 17, 2001 Share Posted March 17, 2001 Chris, the plugs I gave you are Champion RC6YCCs. Its just that they have been labeled Unipart to suit Rover. They are made by Federal Mogul who label them under the Champion brand for aftermarket and Unipart for Rover OEM use. They'll be okay as long as you don't go doing much autobahn driving!!

Andy Checkley Posted March 18, 2001 Share Posted March 18, 2001 VVC Spark plugs! I would not bother with the standard Champion Platinum plugs at all. I had a very repeatable problem on trackdays with the standard plugs. Usually just before lunch the car would develop a misfire under load at about 6,000rpm. If you just replaced the plugs with new (Caterham supplied) Champion plugs the problem disappeared until the next trackday. Using a slightly cooler running NGK plug, which I believe is used in the Elise racers, solved this problem. If you checked the impedance of the Champion plugs after the problem developed they were all different. Not being an expert in these things I suspect that the plugs were breaking down with the additional heat generated in the engine on trackdays. The NGK plugs I used without any problem was a BKR7EVX. (About £30 a set instead of £60 for the Champion plugs) Please do your own further research and speak to an NGK dealer, but this sorted my problem.
