Its been nearly a year since the last update on this thread.

So been drag racing and track daying still then laid up for the winter, a one off film shoot (street dressing in a local period film).

I've added a manual fuel pressure regulator so I can turn the boost up more (15psi now), although drag times don't seem to have reduced much it feels quicker. I need better traction wheels as the track days tyres are designed for some heat, drag is stone cold and spinning up doesn't really help.

I've chewed a CV joint causing the cars first every recovery truck, annoying because I could have repaired it on site but mistakenly identified the gearbox as the fault. I think the cause maybe grease loss as another joint was also loose, not sure why yet. Seems to be leaking from the metal-metal joint at the flange.

Brake size increase still on-going slowly, have made some pipes to duct cold air into the disks.

Fuel surge modifications still to be applied.

Modified the rad to reduce the blocking bits and added baffles to increase the air flow.

Looking good!

Notice you haven't got a radiator shroud on - am I right in thinking this is designed to aid cooling because it covers the radiator or have you found it to adversely affect cooling?

15psi is pushing that little 13c to the max now, might be worth considering an upgrade to a slightly larger turbo from the same family? 15g, 16/18/19t etc?

Yeah the radiator shroud is just to make the fan more efficient at idle/low speed IMO, maybe protect the disti from water. It blocks it at high speed where I am having the temperature rise (max throttle track etc). I am feeling confident the rad mods (removing 1-2cm of blocking material top and bottom) and the baffles will bring this just into spec, but not tested yet because of the CV failure. I think I just needed about 10-20% more cooling. Next step is the wider intercooler.

The 13C seems to manage 20psi no problem, but I know the word on the street is this is pushing it creating extra heat. I'd really like to measure that, but not got decent logging setup yet.

So I've been doing more mods and track days, but not sure its getting as much better as I'd hoped.

Fuel mods
Trying to pump up the leaky swirl pot in the tank with some success. Taking the lob joiner pipe and pumping from that into the inj pump inlet and the tank. Helps me down to about half a tank now, but then starts spluttering briefly on some corners, and recovers quickly. Have found a place above the gearbox for a small custom spirl pot.

Found space for a pump

little bit of pumbing
Brakes
Increased to Mercedes A class 276mm disks and calipers, still problems to resolve.

Bigger disks
Cooling
Current mods of opening up radiator and baffles seems to be working in current weather, but did get a little warm in the hot weather (only by a few degrees). Might try and get an aux rad in under the intercooler.

Power
Put in an A-cam, buggered if I can tell the difference. Even with the better sytec pressure regulator.

Looking good Tony! Surprised you didn't feel much difference with a cam swap, the 'T' cam felt as flat as a pancake above 5000rpm in a 940 I once owned.

Great work on the brake conversion, they're a much more appropriate size for the amount of power you're running now!
