Civic running well at Gurston, with a big PB at the last meeting.. and more three wheel action!

Yokohama tyres are clearly great, and worth a chunk of time. Drove home on the maxsports (to save very expensive yokos) and the grip that those have when warm was incredible. Must be great on a rally stage.

No further mods.. pondering a steering wheel change.

Too much time since the last update, and a pretty average second half of the season. Couple of decent runs meant some good results in the damp, but couldn’t get back to matching my best times in the dry. Guilty of overdriving but not convinced the car was quite as sharp.

A check of the front suspension revealed the coilovers were loose (again). I’ve lost patience with those, so replacements have arrived.



Shame that it’s not really an upgrade, but BC Racing seem to have a decent reputation and good that you could buy just the fronts.

So at 130k miles I’m having the timing chain changed, and predictably it’s stretched. So that was probably overdue. And I’m taking the opportunity to drop in some cams. Will be interesting to see what the mapping brings in the new year.

Hoping to try some different events in 2024, hoping for less rain.

What were the previous coilovers? Yellowspeed? I really need to have a look over my TEIN ones at some point, they’ve been on there a while.

I did my timing chain recently, similar miles and it wasn’t stretched too badly. Pics on my thread if you want a look.

Yes, they were Yellowspeeds. The garage swapping them over also runs Civic Cup cars, and he mentioned that even the more expensive Yellowspeeds work loose on track (they loctite them all).

I'll ask bad the old chain was stretched, it's just reassuring to get it done given it's use and age.

That's a bummer frown

Seen this at my pals (Grinspeed, up this way) re the Yellowspeed coilovers... The BCs should soon get you sorted. Have you gone for custom springs rates?

Yes, but I’ve only matched the spring rate that was already on the yellowspeeds. That seemed about right for how I use the car.

I’d say that the chain was well due..

If anyone needs some car prep support down here in the SW, I can recommend One Day Motorsport. Brilliant service again.

So a couple of test drives has shown an annoying occasional “clonk”.. all suspension exactly where it should be, so looked at new intake positioning. And yes, more clearance required from the slam panel at the front of the engine bay.. not helped by the bottom strut of the slam panel missing its bolt, so that nicely flaps about. Providing extra clearance isn’t exactly a fine art. Hacksaw and hammer being the tools of choice. Hoping that’s cured it.

Winter hibernation coming to an end.. car off the stands, and started on the button. Always reassuring. Mapping session booked in for early March, so that'll be an interesting day out in south Wales. Just hope the drive across there is ok.

Before that I'm going to get a proper sump baffle fitted. This being the version that is supposed to be decent (Clockwise Motion) and not loose it's flappy doors (which can have terminal consequences if it then blocks the oil pick up). Oil needs a change anyway, so aiming to get that all done well in advance of the rolling road.





Civic has been joined by a new stablemate, will I cope with changing gears from now on???

Good call on the Clockwise baffled sump .

They are said to be very good and i would have gone for one but in the FN2 you have to do a oil pump change so it comes in at around £ 1,400 so i went for a Spoon bafled sump in the end that was much cheaper .

Have you installed drop in cams ?

I will be doing the breathing upgrades ( CAI , 4-2-1 manifold , 3 inch exhaust RRC inlet manifold and Ecutek remap ) in the future but was unsure on the drop in cams from a £ to BHP point so would love to hear your thoughts .

Yes, Skunk 2 cams have been dropped in when I did the chain. Was the time to do it, and the chain was definitely overdue. Get the impression that the sports cat is going to restrict the numbers quite a bit, but hoping for a 10bhp + gain (was at 230bhp). I'll let you know the results following the rolling road, plus also how it affects the torque across the range.

Yes would be good to get your views on it as i may have to stick a set of cams on the shopping list smile

What made you go for the Skunk2 inlet manifold over the RRC as i was told the RRC is the best performing unit out of the lot .

This test me that it was unlikely to be significantly worse.

Worth looking at those graphs and having a think about the working range, that ultra street makes the most power but that's mainly cos it has the shortest runners. It's the best at peak RPM but one of the worst in the upper mid range.

Pretty crap write up to be honest, all it bangs on about is peak HP. Punch out of the corners is often where a lot of laptime can be made, this is a consideration I have a lot with circuit racing and I would think it's even more important for hill climbing.

It's all relative - perhaps worth spending some time pondering if you're trying to gain every last advantage in a one-make series, however IMO the time would be better spent 'in the seat'. Having run a Skunk2 inlet previously on a K20 they're not exactly bad either, it replaced an RBC inlet and after mapping to ensure the engine was 'safe' there was honestly no noticeable difference when driving. Far more beneficial was the DC5 gearset I had fitted (with a 1.5 way LSD and 4.9:1 final drive), lovely ratios and kept the car in the powerband far better.

Once you've done a good bit of reading, there's a very good case for either of the options. I don't think I'll be in a significantly worse place, and the cams will also change the car across the lower revs as well. Will be interesting to see what the results are, and how much the cat constraints the overall performance.

So a fairly terrifying journey over to wales for a rolling road session yesterday, the snow was just a bit unnecessary. Can’t remember that last time I was so uncomfortable driving on a motorway, not pleasant.

Results of the mapping session was just about what I expected, with a peak power of 244bhp. My exhaust manifold with sports cat set up costing me a fair bit. Something to deal with in the distant future perhaps, but still a good gain from where I was. Will be interesting to see how it feels at an event.
