The aero screen bug is hitting me. If you have one that you don’t need, let me know!

Hi thanks. I bought a 985 from SBD. And they are going to renew 9A4 with 9M4, which I may get later.

Sad to see you are selling the car… I am also in AZ. Btw do you consider selling the seats separately? Thanks.

Hello 7 owners, I am looking for a used MBE985 ECU communication module and/or a MBE 9A4 ECU unlocked. Please let me know if you got anything! Thanks!

Yes. I have done autox many times but found I am more of a track guy clearly. 😁

This was my experience when registering my 7. I actually didn’t need to transfer the original title to my name, which is a bit different from your experience. Anyways welcome to the club! There are a few other 7s that run track days with Porsche club. Would be fun to get together sometime!

It’s a detour of the thread. But today I drive my Miata track/race car after I drove my 7 on track last time… I never thought my Miata was not balanced until now…

Thanks guys! I did have a lot of fun and got to know some other caterham owners. Yes, during street driving the fan and temp behaves just like you said, turning on at 105 and then temp goes down. The part I don't like that much is on track, the car is going to or a bit above 105 since I would think on track, fan is not the major source for cooling. At least that's what usually how my track Miata do. But agreed, maybe it's just how the different cars cool. Btw, my car has dry sump and oil cooler. Sadly no ac though😂

Hello guys, here i come again... I did a track day with my 420 duratec the week before and I am so happy with how the car performed! Super fun and sliding around But I do have a question: in the afternoon (ambient temp ~70-75F), my coolant temp slowly creeped up to ~105C range at the end of the session. In the morning, no issue at all the car can do whole session at 100C. I am running zetec coolant (yes, not water since my 7 is more of a street car). Is it normal that the cooling cannot keep up at this low ambient temp? Any improvement I can do? BTW, here is a video from my track day!

If I remember correctly, from my experience with dji, it will try to follow until it thinks it lost the object and then will start hovering around…

Yep. I found a dynojet As long as it's safe, I am fine at least for now, I am not too worried about powerrrrrrrrrrrrrr...

Update changed the spark plugs and went to a dynojet shop for dyno. This time numbers seems much reasonable. 160 who 130 wtq. But the shop is concerned about AFR seems to be very lean at lower rpm. Do you guys see the same? I see @SK400has similar AFR but that’s on roller barrel. Ideas? Thanks.

Plan to change spark plugs and redo a dyno on a dynojet with AFR. Any other idea on starting point for troubleshooting? The issue here is I don't have any shop who is familiar with Caterhams...

Hello @sf4018, thanks for the information! I am wondering if the dyno is the reason. Will try with some other type of dynos. Thanks!

May I know what kind of Dyno did you use? I am thinking to use another Dyno to verify now... Thanks.
