Made up the brackets to hold the fuel rails in, so now they are done. I used some scrap steel angle to make up some spacers (expertly cut with the angle grinder) to go underneath the brackets and give them the required height to get over the fuel rails. The brackets were 4mm sheet bent to the right angle to match the top edge of the rails. 4mm sheet is very rigid, which was good for holding the fuel rails in, but also very difficult to bend. A hydraulic press and a jig did the job, albeit narrowly averting disaster when the jig slipped at one point. A bit of silver paint to finish them off and the brackets mounted onto holes already on the throttle bodies.
Because the fuel rails are in different positions to original, the crossover pipes don't reach. Working on fixing that with new banjo fittings and braided lines.

OK, so it is in serious need of a tune as it is currently running on the settings for the old engine, and there is no gearbox installed yet so the engine isn't really bolted in...
But here is first start-up of the new engine.
Improvements over the old engine:
* Higher compression * Much bigger cams (higher lift and longer duration) * Bigger (440cc) injectors * Coil on plug packs (supplied by Clayton) * Individual throttle bodies * Mild port clean-up * Running on Avgas (old engine was 98 octane)

Grrrr, I can't get the clip to run on my phone. Is it on YouTube? Looks so cool Andrew, the blue against the chrome. Have you got a map sensor & IAT sensor or is this impossible with the individual T/B's? Actually that must be a stupid question as you can't run MAF or air flow meter. Umm just thought about it & I'm guessing there must be a vacuum line running from each two T/B's into a single line & into the Motec internal MAP sensor, is that correct?
Please let me know when your going to test the car Andrew as I will def come & watch/help out.
I have a spare TPS if you need to borrow in a hurry.

Ok I just saw a close up of the throttle bodies & there is a vacuum on the outside of each one. Have you got these hooked up to a map sensor yet? Sorry I can't watch the video right now on my phone. If you haven't done this yet it may run better after. I'm pretty shocked it started with the old map on those new cams & gas! Did you change the injector rate tho?

No MAP or AMF mate. Motec gets load from RPM & throttle position, which is why having the busted TPS is a hassle... It also gets info from engine temp and air temp (which it uses to estimate air density).
The only vacuum line we're running is for the power steering. I don't even know what that line does, or how it affects the power steering if disconnected. It was connected on the original car and I've always had it connected.
All other vacuum outlets on the ITBs have been blocked and will not be used.
The old map was good enough to start it, with a few tweaks (like having 8 coils instead of 2, which is why I needed the dwell info of the coils off you the other day). It is not good enough to run it though. For a start, with the bigger injectors it is running WAY too rich. Ignition timing is different with the cams too.
Still lots to do before a test run, but I will keep you posted.

Ah wow, I feel like a dummie now. I guess Motec have mastered it as they are top dog. How would it read boost I wonder? Anyway how's the gearbox coming along? I think a lot of people like myself would like to see a Dyno clip of this! Besides I think Ben just smashed the Soarer record at Wakefield. Or was Damien still faster?

Not sure how the Motec reads boost, but I do know they have the capability to handle all sorts of inputs - including MAP and lambda sensors - so maybe that's how the turbo stuff goes.
The gearbox was stripped down and checked out and is in excellent condition. Still waiting on a new input shaft for it and we have to figure out installing the hydraulic release bearing. The rest of the gearbox installation is ready to go though - flywheel, clutch, bell housing adapter. Then we need to modify the tail shaft (already have the bits and a plan) and then it should be right to install.
Not sure on the lap time question. I know from reading the lap time thread that Ben is the only one who has posted his time up, so that makes him the fastest. Aaron thought Damien may have run a 1.06 but nobody has confirmed it.

Rumours are horrible things. Full of truth and innuendo.
Yes, the rear subframe was reinstalled last weekend. I have no photos. New adjustable toe arms and trailing arms, new bushes all round and the upper control arms had the ball joints removed (you know, the ones Toyota say are non-removable and non-replacing) and replaced with spherical bearings and newly machined tapered pins. I should have photographed these, as they were a work of art as well as mechanical prowess, again thanks to AGM Engineering. I'll see what photos I can get now it is back in the car...
Other progress: Gearbox adapter modified to mount the hydraulic bearing for the clutch, and the clutch installed on the flywheel so that everything could be measured up for the new input shaft. Just waiting on the input shaft to be made, then the whole gearbox, clutch, etc. can be installed in the car (the engine is already in).
Then it will be the tail shaft and a couple of other minor bits to be made up, then I can start it and move it around under its own steam.
Also still fibreglassing, with the ducting for the air intake almost done and the radiator ducting essentially done but needing fine tuning to mount on the car.
