Sharpness is all to do with contrast. With these photos, the blurred, smooth background provides a high edge contrast around the relatively sharp car, giving a greater impression of sharpness.

In reality, they aren't nearly as sharp as the same photo shot static, since the blur requires a slow shutter speed (which leads to potential camera shake) and the relative movements of the tracking car to the car being tracked.

The skill element with a tracking shot lies in being able to hold the camera steady enough to get a sharp picture, whilst hanging out of the boot of a car doing 40mph over rough tarmac. Then you put in the light, and the composition and any little details, and you have a good photograph!

You can also use a rig - meaning that the camera is attached to the car.

The rig is then Photoshopped out. A lot of smoke and mirrors involved and from my experience no two photographers use the same rig/techniques.

As is the first shot on this thread!

Jamie, I've just looked at your website - your work is outstanding!!!
Your 911 is absolutely beautiful, too.
Just be careful of that carb cleaner so near to your MacBook Pro!

Keep posting your stories and fantastic pictures.

Cheers Stu.

OK... Took a few days off to get cracking with this EFI conversion. Hiss boo pop bang. Bye bye horror Zeniths!

It was always going to happen that as soon as the time for the conversion got near, the carbs which I planned to replace would suddenly begin running perfectly. And they did. A friend offered me use of his workshop, and the drive down there was just amazing.

But they are fickle little sods, so off they come.

Simple job turned into a massive bitch - mainly due to my custom injector spacers requiring longer port studs. I thought the old ones would come out easily enough, since this side of the engine stays relatively dry and cool. But having done the exhaust studs 18 months ago I should have known that wouldn't be the case.

Got five out after a night soaked in WD40, then Tim my mechanic friend freed five others. I snapped two, and Tim drilled them out (by hand, with an 18V cordless drill - the guy is skilled - as in, skilled enough that the stud thread could be picked from the hole and was the same thickness all the way along).

The other big job was fitting a new high-pressure fuel pump at the front of the car. I opted to jubilee-clip it to the front cross-member - the same place as the feed pump on CIS cars.

If anyone else ever comes across this thread thinking of doing the same thing, make sure you have an empty-ish fuel tank, since doing this on a ramp, above your head, with a 3/4 full tank, will drench you right down to your underpants. Fuel stings your eyes, armpits and man areas a lot, and will make you unattractive to members of the opposite sex. No matter how much you dance around in your fuel-soaked pants, it will still sting mercilessly. A good time to quit smoking, a bad time to learn how to weld.

It took two full days before the intake manifold made it onto the engine, but it looks cool. Have to connect the engine-end of the loom together, fit a pre-pump filter, wire the pump to the relay and work out a way of controlling it without running another wire from the back to the front of the car, and adjust the throttle linkage (too short) and tune the system. So another few days of work...

Took some pictures on my phone:

This is Tim blowing stud swarf out of my engine bay.

My custom injector spacer blocks. I made these to raise the height of the angled injector and so remove the need to notch my intake ports like on a later CIS car. Another benefit is that the CIS intake is raised and the runners don't foul the oil cooler duct, thus removing the need for a later-style CIS engine shroud.

Carbs out, engine cleaned up a bit and injector spacers in place.

Mmm... homebrew gypsy spacers. New longer studs with copper slip to help out the nutter that next plays with the engine in 36 years time.

Can work a spanner, but can't work out colours on a wiring loom.

Where I am at now...

Hey, Nice spaghetti Jamie

Looks like a neat install too (Once you've sorted the wiring of course)
I thought I'd warned you about some of the unpleasant properties of petrol !!
Just let me know if you need a hand.
Cheers
Tim

Brilliant tale so far Mr Lipman, although slightly disappointed that you didn't manage to sever a finger using just a cotton bud

.

Good luck with the next stages.

Cheers guys. Tim - I wouldn't offer to help because next thing you know I will be sitting outside your house with the passenger door open and a 100-mile trip south on the cards.

Got to wait to do the wiring install as I am really jammed up all this week.

jamie · Post by **jamie** » Sat Aug 23, 2008 10:24 pm

Finished the wiring off today with the help of an electrical engineer friend who happened to be hanging-out at another friend's workshop where the car has been abandoned the last week.

We (mostly he) fitted a new fuel-pump relay next to the fuse box.

I had this idea that the ECU pump signal could be sent down the old pump live feed in the existing loom, which meant not having to cut anything up or run any new wires back through the car. He looked at the wiring schematic on Pelican and discerned that this was OK (nothing else tagged onto the wire), so that is what we did. It's very neat.

My new pump power supply runs through the smuggler's box and down to the pump, which meant nothing had to be drilled either.

I never realised it, but the electrics on these old 911s are a total bugger's muddle! Bridges, random live feeds, dual-fused madness, and it's all factory. Very odd. Very un-German.

Anyway, we completed the job, plugged the ECU in and cranked the engine on the off chance that it would run...

IT LIVES!

Rough as shite, but it lives.

I couldn't believe it. Dead happy. Now I need to learn how to tune it up with this Innovate WBO2.

The fastest EFI install in the world

I spent a couple of hours this afternoon resetting the Zeniths after a spirited runs across the Peak District. They were all over the shop! about as balanced as a one legged tight rope walker

See all the fun you will be missing?

jamie · Post by **jamie** » Sat Aug 23, 2008 10:44 pm

No.

I won't get too excited till it's tuned and pushing over 400bhp from that might T motor. I reckon I'll get that after a few hours of number-crunching. Yep...

In fact, now I think about it, the hose to the MAP sensor in the ECU wasn't even connected. I don't understand how the thing ran, but it did. I even moved it to a different spot in the yard, so it drives. Weird.

I like it though.

impmad2000 · Post by **impmad2000** » Sun Aug 24, 2008 9:27 am

Congratulations. Quite the "Eureka" moment when it fires and runs.

Cool eh

1)Make sure it ticks over
2)Make sure there are no "resets"
3)Make sure the Tach trigger is solid, no misses.
4)Make sure all the sensors are working, IAT,MAP,O2,CHT
5)Make sure it throttles
6)Try to go for a drive, with a tuning buddy. Tweak as you go
Great news Jamie

Rolling newflash:

Spent the morning over the road at Mani's (Manipou) workshop. We were going to fit a rear ARB, but it turned out to be a bit of a severe welding endeavour without moving the old fuel pump bracket, plus the trailing arms didn't have the rear bit of plate for welding-in the ball-socket peg things. Instead of cocking about with all this, I fitted some Weltmeister bracket adapters I had bought a while back - they bolt onto the torsion bar and mean no welding. Need to buy some sort of aftermarket rear ARB that attaches to the trailing arm bolts instead...

Whilst the car was up, I then did some work on the fuel pump area at the front - fitted posh glass inline filter before the pump and re-jigged the hose to tidy things up a bit. The pump is also now mounted on some rubber, to reduce the noise a bit. I forgot to take a picture, but the install looks wicked.

Thanks to Mani for letting me use his ramp. One day I will have a garage with a two-poster! Or a bit of fork-lift truck like optician-dentist Mike

I did a bit of pikey-tracking on the rear nearside wheel, which was squiffed since I took it all apart to fit my SuperPro mounts. Should be good enough for the impending trackday!

Drove the car home - all 30 yards and did a bit of mapping on my idle. Got the MAP nice and low, and it idles stable at bang-on 1000 RPM

Nice.

Back on it after a bite to eat...
