If you think your car has a loud rattle. You should hear mine. I have a multi disc clutch for the paddle shifter that my mechanics say is normal to sound like a box of rocks when idling. And the whine from the straight cut gears is like a B52 taking off. :drool:

Get R Done John. In fact Croc and I were just talking and we decided you should get a spare one done up too just in case your son gets too exuberant again :smash: Hopefully it will be done by October. Can’t wait to see it go. Tom

I don’t know your plans for it, but in those pictures it has the aeroscreen so make sure you wear good eye protection or a helmet when you take it out. Bugs and stones hit really hard at speed and even with the clams you will find a ton of stones on your seat after a blat. Be careful and enjoy. One last tip. Make sure your steering wheel is straight when giving it the stick.

Welcome. Seriously? It’s an S3. Which means Series 3. Itis the standard size Caterham. Those other numbers are irrelevant to your model. Oh. And welcome to the clam club. Clams rule!!! :rofl:

Guys not to be a downer, but I chased bubbles at high revs pressurizing my coolant tank for a couple of years. Tried Evans coolant. Replaced water pump,radiator, installed one way valves and moved the headertank to the highest point. Tested for exhaust gases in the headertank. Negative I installed a higher pressure cap which worked a little better but I still got pressure build up at track revs. After each track session I would winch my car up the trailer ramp to put the tank as the highest point. Bubbles would bleed up into the tank and the level in the tank would go back down to normal. It did appear that the higher pressure cap prevented it blowing out the cap. I would do that after every session and the car ran fine and did not overheat. BTW. I ditched the Evans and went to straight water with water wetter. I had enough of this so I did an experiment to see at what revs the pressure built up. I ran successive session on track at fixed RPMs starting at 3000 and cranked it up 500 RPM in each following session. No bubbles/ pressurization at revs under 5000 rpm. At 5500 RPM. The pressurization and bubbles in the system showed up. No loss of coolant. No gases in the tank. But after all the time, money on part replacements and huge denial. I finally pulled the head and replaced the head gasket. There was a small area that appeared to cause the issue. After reassembling, it runs great with no pressurization or bubbles in the system. May have no bearing on your issues but just felt the need to share. Best of luck. Tom.

Mine appears to be just slightly angled

It’s from a rover. Caterham used to stock them

I have a 2000 Lhd Hydraulic clutch. what do you need.?

True story, I let Maureen sit in my Yellow S3 and since she is very tall and leggy, I told her that she should try the SV next to mine to compare. She asked if it was mine and I said no but the guy who owns it wouldn't mind. :drool: She gets in and I could see Croc across the lot trying to figure out this Blonde sitting in his car. Maureen BTW is a long time member of the NJMP drivers club and is a shit hot driver of a Lotus Extige. Her husband Steve, is a customer of Tom's having taken delivery of a new Birkin last year. We really did have a good time at that LOG, but only because we bonded as 7s owners.

Mike and Mike. That event was epic. Starting with Croc leading us 7s on a wild escape over hills and fields back to the hotel. And where I first met kitcat on the autox course helping to fix some loose front a arms. Then his hotel parking lot encounter, which had a lot more detail in the telling at the time. The track day at summit point and kitcat getting caught in a downpour on the way either home or to summit point. I’m a bit fuzzy on that. Ah the good old days.

You forgot to mention you fixed your fuel gauge issue too with the swap. :leaving:

Nice work John, Hopefully you will have a nice smooth break in, and be out hooning around shortly. Good Luck. Tom

Croc, Simon, Jeff and I had a great day on track yesterday on TBolt at NJMP. That track is really good for our Sevens as it has some nice tight sections with weight transfer areas that really play to our light weight cars. NJMP seems to have their act together as far as the logistics go. Sign in and tech are outdoors, masked required and everyone seems to be social distancing properly. Drivers meeting was outdoors, over loud speaker or you could sit in your car or truck and listen in on FM radio. Breakfast was outdoors, while the chef was inside handing the plates out thru a pass thru window. Lunch was plated and set at tables outdoors, Some played nice and sat at the opposite side of a long table, others not so much. Option to take it out and eat back in the paddock was available. Most drivers set up chairs in large circles 6 or more feet apart and that seemed to work pretty well for socializing. All in all, very well run IMO. We are now just over 3 months away from our 10th annual Se7ens gathering at NJMP. Seems Croc and I got lucky in pushing the date later in the year than usual eh? Just wanted to give you all a heads up and prod you to get your cars ready while you still have time. Don't wait until the week before as usual. :smash: Hopefully things will get better in a few more months. There has been a few management changes since last year, so Croc and I have a little more work to do to get the registration process finalized, but that shouldn't be a major issue. Stay tuned. Stay Safe. Tom

Vlad, you probably have a Sierra Diff with the ZF plate type LSD. Tom

You choose :seeya:

The old style front “wings”/fenders are known as “Clams” as in clamshell. I have a 2000 Caterham and when I ordered it they were still available although I heard that they only did a couple with them that year. I specced mine with the wide track front end which was never usually done but the standard tires do just fit within the width of them. The nice thing is that you can stick 10 inch wide Hoosier slicks under them no problem for autoxing. Downside is you can’t watch your front wheels bounce up and down when driving. But you can always buy a second Caterham with the cycle fenders if you get the urge to see them. Worked for me :rofl: Good luck with your search. http://www.usa7s.net/vb/blob:http://www.usa7s.net/98441bc3-a3d0-4d7d-92b4-7e9dd58926d6

I have an S3 and an SV with lowered floors. I'm Just over the Delaware state line in Pa. You will fit in either car. Biggest difference is in the footwell size. The S3 requires pixie boots to drive. The SV you can get away with a normal shoe or running shoe Assuming you don't have size 15 feet. The S3 will be snugger but you won't slide around at all. The SV, depending on the seat choice you will have a lot more room. IMO.

Cem Congrats on the new car and welcome. I have a Sadev sequential mated to a Duratec with about the same HP as your 620R, althought mine is normally aspirated. You will love it. It's a great gearbox and no lift upshifts are thrilling as the power just keeps coming. But mine also does rev matching downshifts too but I do have to lift for those :driving: If you haven't driven a 7 with 300+ hp you are in for an experience. BTW I had a new clutch installed this winter and since the gearbox was out, I sent it to Sadev for a refresh. Great service, turned it around in two days. I had the car out this Past Sunday and I'm still smiling. Had a slight issue during the first session, where it got stuck in 6th gear, but you won't have that problem. Luckily it was easily corrected back in the pits. Good Luck with yours. Tom

Mike, I believe it’s up around 9200 with the crank that Karl specced For it. I know they took it up over 8700 when I had it dynoed I however find no need to take it that high. I scare the crap out of myself at 7000rpm

Hi John. Sounds like you are going to be social distancing from all of us on the track with that new beast of a motor. Hopefully we will all be in the mood to burn some hydrocarbons to Help get that global warming thing back on track. . Can’t wait. Tom

The plastic dowels on the early k series did cause head gasket issues. They were later replaced with metal ones. That helped correct that issue. Speaking from experience

Beautiful! When your battery dies there are lots of nice smaller low profile options available. You can lay them down as well. Remember to add lightness! Good luck with the first test drive. . Tom

Lighten up guys, it's a Joke!!!:smilielol5:Shane, they obviously don't know you like we do. :seeya: Tom

I asked the same thing Michael. Apparently it created a lot of heat.
