Had a great day on track with SEXIGE on Sunday and thought I'd share. The car is going great now and ran trouble-free all day :)

This was the first session of the day, and was a bit caught out with the extra grip from my fresh Toyos on the first corner and ended up apexing early (got the blind entry wrong and apexed the penultimate ripple strip rather than the last one),ran a bit wide onto the grass, but was a pretty good session:

The third session of the day was brilliant fun, I got to have a bit of a play with a freshly built V8 Supertourer (NZ's version of the Aussie V8 Supercars). These things are normally a good deal quicker than me, but this one was having its first shakedown run and I was just about to keep up for a lap or three. It was also my personal best laptime at Hampton Downs, lapping in the high 1:13s bracket, which is pretty nippy.

I love my car :)

Yeah that S14 was very quick and fairly well driven. It monstered me in a straight line and not bad in the corners, I was only really making lots of ground up under brakes. It's a good example of how a car doesn't have to look crazy to go fast, it was very subtle.

Well, I made it out to the track again this weekend just gone. Two weekends and two trackdays. Car ran almost faultlessly again and went even quicker, despite running more fuel and a less-grippy track.

This is from the second run of the day (first being a warm-up):

And this one is the third, where my third flying lap was a new best lap for me around Hampton Downs of 1:13.5s:

This session was cut short by a high oil temperature warning, that made me s**t myself. However, subsequent sessions showed it to be nothing more than a dying temp sensor, which is on the cards to be replaced. Even so, I restricted my pace for the last couple of sessions.

She's quick! I'm not sure how many road-legal cars can turn Hampton Downs laptimes like this, but there can't be many. With the car getting better and better, and my driving having another second or so in it, it's not doing too badly for itself! It's also so nice to drive quickly, it has very few vices and while it's not an easy car to drive fast, it's a very predictable car once you get it up to pace. Just how I like it!

Oh dear, it seems we find ourselves here again! :(

I took the car out at about midnight tonight, I'd not driven it in anger since the trackday a couple of weeks back and thought I'd take a midnight run out to Bethells Lake out in the Waitakere ranges. Had a lovely drive out there gradually leaning on the car more and more. Out towards Bethells the road really tightens up and it's all pretty much from the bottom of second gear to the top of third and the car seemed really on-song and healthy. I wasn't really hammering it, generally shifting at about 6800-7500 or so.

Then, just as I was nearing the end of the road I heard a nasty metallic buzzing/rattling sound so I immediately backed off it and could hear all sorts of mechanical knocking/banging as I slowed down.... sounded very much like a bearing had spun or I'd lost a big-end. I coasted the car to a stop and the oil pressure low warning was on and it was down at about 20psi at idle, which in retrospect was about right for the oil temperature (~102 degrees) but at the time seemed a touch low. :(

Anyway, the engine was still running okay, with what sounded like a bit of a knock. With no cellphone coverage I thought I'd try and limp the car back as close to Auckland I could get it without it sounding too awful.

As I drove on, in 4th-5th gear it sounded generally okay, at about 2500RPM it sounded pretty gnarly but if you stayed off the throttle it sounded okay, with just perhaps a slight rattle, and it didn't seem to be getting any worse. As the oil cooled the pressure came back again and whereas before I'd convinced myself the oil pressure was too low it was now reading about normal.

Anyway, I pressed on and it wasn't until I came to a set of traffic lights in Henderson that I finally figured out what was wrong.... I changed down into third, and then down into second and then GNAAAAAARRRRRRRRNNGNGNGNGNGNNGGNNGGNANNAANAGNNGNNANAN..... FUCK!

I came to a stop, and at a halt, it generally sounded okay, pulling away in first again I could hear a slight rattle but then when I slotted second it snicked home with no synchro action at all and I could hear a KNOCKKNOCKKNOCKKNOCKKNOCKKNOCKKNOCKKNOCKKNOCK through second that was quite loud. In third gear again it was fine bar a light rattle and 4th/5th/6th it generally sounded just fine.

So to me it sounds like it's knocked a couple of teeth off second gear or a baulk-ring or something has flown itself to bits inside the box. I got it back to the workshop and the engine oil level seems just as it was before I set off and looks clean, second gear is definitely gone though.

I guess right now I'm just feeling a bit thankful that it's not a big end, as I'd really rather not rebuild the engine again right at this moment, but it looks like the box is going to have to come out and apart again..... At least Ken's used to getting it in and out again now.

It's a shame though because I was just beginning to get confidence in the car as it'd run like clockwork at the last couple of trackdays, now I'm back paranoid again. I might treat her to an oil and filter change before I take the engine in, at least then I can inspect the oil filter to make double sure there aren't bits of big-end floating around in it.

Oh well..... sodding car.

Sadly, I bought the box used, it's second-hand so Quaife have no obligation, and even so, a warranty wouldn't extend to this.

The box has seen a few seasons racing and while it's been rebuilt/serviced before, that's only extending to replacing worn components. This 2nd gear may have been overstressed before and the damage is only now becoming clear. When I strip it this time, I'll probably send all the internals off for crack testing to make sure there's nothing else there about to go tits-up. It's just a case of it never having been rebuilt properly in the past and it's now coming back to bite me in the arsehole.
