If Dempert are no longer making this Gaz from Spitfire who is on the forum has a solution. He may be able to make something that achieves the same outcome.

Hey Guys,

I had a few difficulties but my engine is now running after a long time. 

The Video has german subtitles, but you guys can see it running there. 

Its running really rough because the amount of fuel isn't right now, the ZZP-Stage2 Cams, and the "missing" balancer shafts.

But it sounds really nice when I rev it.




In the meantime I refreshed my rear axle with new screws and so on. 

I also added an oil thermsotat to bypass my additional oil cooler when the oil isn't heated up. 

To do that properly I had to buy new hydraulic lines and in the same process I connected the oil-water-heatexchanger in the right way (counter flow princip).


I also fcuked up one thread in the intake manifold because I had to shorten the screw to get it into the mounting hole from the harrop (the one next to the TMAP-Sensor).

So tomorrow I will buy a helicoil-set and then I can reassamble the car.

Wonderful mods,

by any chance, do you know if the reinforcement bar between the two toe links is still on the market?

Hey gozer, 

sorry for that late answer. 

I have been very busy the last months to get my car up and running. 

Sadly you cant order that bar any more. Dempert Automotive is inavtive since 10 years or so. 


My Engine is running and makes good power. 

406hp until now without WI. 


Here is a video of my last stint on the Nürburgring. 

I think I had some power losses, because of the very high IATs. 

I thought, that my setup maybe could handle it, because I have just 1.1bar of boost. But I was wrong.

Engine was running at lambda 0,75 and made 5° ignition retard.

IAT was an average of 90°C.


Next time with WI it will make some more power and will hold it on the track :)
