Peter Empson said:No track days for me for the foreseeable - long story short(ish), it has had low oil pressure for ages (well before the SC was fitted, as I though it would make more sense to grenade a worn engine than a fresh one). Not sure if it's rings or scoring but possibly both (although compression was pretty good last time it was checked).
I had been running the engine on treacle to keep oil consumption reasonable without problem but then due to poor communication my garage they put the normal stuff in. I thought it'd be ok, but in about 10 minutes on track the oil had run seriously low and the top end became noisy (which was recent and of very good quality). Shortly after the headgasket started to leak slightly - this was my fault I suspect, I was never happy with the transition between on and off throttle of the mapping, but given my DIY efforts I got a lot more track days out of it than I expected.
So I have to decide what to do next. A few years back a build of a new engine was started, but due to circumstances beyond my control I had to divert funds elsewhere. I plan to resume this one day, it'd be lower compression so we could increase the boost, with a dry sump and so on. For the time being a stock S2 lump may just be dropped in, it's a bit of a waste of money long term, but would get it mobile more quickly.
I'm at that slightly difficult point where a lot needs doing to recommission it properly for track use: engine build/swap, possible calipers refurb, tyres, professional remap (possibly with a move away from the Scivision MAF to something more accurate), geo setup and so on, so I'll aim to nibble away at them as I can. If it can be on the track next summer I will be very happy, it'd be a nice way to celebrate its 30th year (what's left of it anyway!).
Yes mine's 30 years young next year too.....
Oh blimey, I don't relish the rebuild situation having had my car off the road for 3.5 years whilst the project escalated from one thing to another and a lot of the items
you've mentioned were also the reason for this huge delay! What started with fitting 2 kevlar race seats, then became lexan replacing glass, fibre replacing steel panels and then the chunky stuff popped in my head and the engine and box was out! then the whole rear suspension, then the front etc..etc..it was virtually down to a shell.
Now it's done and being well used and abused it's a bizarre feeling not having to think about finishing a big project, however it's just starting to reveal to me today after 2 hours of intense driving it really is a waste on the road and I should consider caging it and having a crack at Circuit racing, only because it wouldn't take much but also as the diversity of cars and talent is very wide looking at the CSCC series.
However it would be a shame to take it off the road again ! As I would then probably never be a road car again, but set it up as a full race car and I would trailer it, I don't fancy driving a half hearted effort to events and back..
I've only done 2 Trackdays (944 @ Brands & 928 Silverstone GP) and I didn't enjoy them much due to both cars not handling good enough for me, as they were both my daily's and on soft road suspension.
