Got it back. Running-in begins...
Discussion
Popped over to Newbury yesterday evening to collect the FD. New engine in. Bit of a shock to learn it's going to need 2000 miles of running in before mapping. Had already come to terms with 1500 miles so this is a bit of a bugger! Thought, for a laugh I'd update this post over the running in period. A mini blog if you like...
120 Miles
First trip, home from Newbury. Bad rain and too many numpties on the roads - I've not driven the FD for over four months now and concentration on the driving is pretty high making the rush hour traffic more of a pain than usual. Main area of concentration is on keeping the revs below 3500 but actually being able to make some progress. Short skip roads are entertaining! Should've stopped at Tot Hill services for a pee.
Choice of M25 with warnings of serious delays or through Clapham Common and round the south circular. Decided to go through town. Potholes serve as a constant reminder that the suspension is still set to it's VMax settings and that I could do with finding a place for a 'pit stop'.
Heavy traffic brings out some of the new portings 'nicer' aspects - idle sounds superb but part throttle is a nightmare. Used between 1000 and 2100 rpm induces learner-like hopping that threatens immediate bladder slackening. the rev limit means it's impossible to keep above 2100 all the time
Home after 3 and a half hours. Absolutely knackered but looking forwards to choosing some less congested routes in future!
505 miles - 07/04
After a trip up to my folks and a Saturday pootling around Cheshire with my brother (Pretbury must have the UK's highest rate of Ferarri and Porsche spotteds going!) I get to the magic 500 miles. Time for an oil and filter change. All goes smoothly but I break my golden rule of car maintenance and can't find any axle stands at my Grans so it's all a bit makeshift.
On the trip up I noticed that the whole thing really really idles badly when hot and the weakness in the part-throttle fuel map is exaggerated. Kangaroos'r'us.
738 miles - 08/04
Pretty uneventful drive home. Not much traffic and having plugged the ECU controller back in I can keep an eye on water and air temps. Water temps stay at a rock steady 85C which in nice. Air temps hanging around 38C which is way to high given no boost and ambient air temps of ~15C so I suspect the usual problem of the air-temp senso heat-soaking is to blame.
7am start tomorro to Castle Coombe to support a fellow Rex owner in his first race of the 2007 campain. Ugh.
Some really nice Jap metal out and about including a pristine DC5 through Stoke that wanted to play. Shame - I'd have loved to be in a position to lay down some manners. There is a hierarchy after all
1018 miles - 09/04
Trip over to Castle Coombe to watch a day of club level racing there. Some fun stuff on show, mostly there to show support for Jon (Atomicrex) in his first outing of the year in the newly built race car. It looked stunning but suffered from a few technical glitches in the race.
Car's running better and better as the ceramic tips begin to bed in. Still running with a 4k rev limit although I'll be upping this to 5k on Tuesday evening. Statrt to build a little boost as well but wil be mainly avoiding it until ~1500.
Half way there!

hope we get some figures soon
'soon' will be somewhat realtive. In 1890 miles it'll be ready for mapping!
Carl does his mapping 'on the road' (test track obviously!! *ahem*) so there won't be power figures available immediately BUT to get decent behaviour for low-load and part-throttle mapping I think it'll need some dyno time. I'll have a chat with Charlie closer to the time to see if he can do me a decent price down at his place
One of his customer cars has the same porting and is putting out 500bhp with only 1 bar boost. The dowelling and ceramic tips mean I could run up to 1.5bar with no worries BUT we'd need either race fuel permenantly OR water injection. Neither of which I'm too keen on at the mo. Looking to map it to 400rwhp for now

How long do you think it will take you to run it in? I did 1000 miles in my Skyline in a week all at below 4k and 0.4 bar of boost
all at below 4k and 0.4 bar of boostank Holiday weekend will involve some roundabout trips - folks up north and Coombe on Monday. Should rack up close to 1k by the end of that. Need to do an oil change though at 500 miles!

you're at coombe monday?
fancy meeting up?

Should be. One of the guys from MRC is racing his FD there (oange and black beastie). He should be right up there for class wins but it's pretty much a new car for the season and you neve know what gremlins might be lurking.
Aiming to get there for 9:30 I'll drop you my number by email so you can text me if your'e there...

Iain, currently doing that sort of mileage in a week... happy to help (assuming you pay fuel!) 
You really really don't want to be taken up on that offer - you'd arrive everywhere frazzled and knackered. driving in slow traffic becomes very old very quickly

Been there, done that... ran the Chimaera as a daily driver for two years...

cheers fella, i know your rex will be faster than the alfa on low boost, but you should hear her

Cna't hear it, too busy looking in the cabin to see if the women driving it is hot or not

lololololol
Have a spare roffle too.
Batty - not low boost - NO boost and no revs to use to build it
I'm currently saxo fodder! Thought the RX7 I saw in one of the carparks (between chicane and last corner) looked familiar....looked just like your one
Looks very nice I must say, although I usually prefer slightly larger rear wings on RX7s (although a little smaller then the one on that orange+black one in the races!)

I've been thinking about changing it to the '99 spec wing, not as in your face at the GT style wings but has some effect. The thing on the back of mine is a '96-'99 spec spoiler. Much nicer IMO than the '92-'96 spoiler but not a patch on the '99+ wing. Pretty hard to get hold of an OEm one though!
