Black magic Mk5 GTI track car
fuscobal:
It's very good you posted the pics there Bruce, I would have done it anyway today (was very tired and went to sleep yesterday). Didn't do anything with the "thank you" button :confused:
As for the next Hring track day that's on 30th of mars I don't know if the car will be ready. The radiator will arrive tomorrow and will install it in no time but I really want to sort out that idle and besides another problem appeared at my first WOT since I redone the engine and that's the clutch slipped wich is really strange as this clutch should be very powerful and has only like 2000 miles driven hard on it. I hope it's just disc contamination and will open the gearbox to check it !

Some measurements made today :
- Forge twintercooler > 5.2kg for the core and about 1kg for each of the 2 hoses (7.2kg all together)
- THS > 11.9kg for the core and about 0.5kg for each of the 2 hoses (12.9kg all together)
- S3 FMIC > 7.6kg (S3+Forge = 14.8kg)
- Hot climate radiator + plastic guide > 1.1kg (about 2 to 2.5kg with all the extra hoses needed for the install)
- Air-con compressor + hose > 6.3kg
- Air-con radiator > 3.1kg
- Other air-con hoses + fluids > aprox. 3kg
All in all I'm cutting about 12.5kg by letting go the air-con system and also gain (hopefully) better cooling for the main water radiator and the intercooler. As for the radiators/intercoolers, by replacing the S3+Forge with THS I will gain about 2kg wich I will then lose again with the install of the hot weather water radiator ! However, had to do it because the aditional water radiators sits very tight against the twintercooler's hose wich can cause problems under high vibrations on the track !

I'm very pleased with the THS IC currently fitted to my car, and would rate it above the S3+Forge TC solution :happy2:

Just came back from my mechanic and the car is 99% ready. Filled the coolant tank with water for the moment and started the engine wich seems to work well this time (no more oscillations for now). Installed the THS cooler with a custom pipe between the turbo and the THS and also the additional hot weather radiator. Since we were missing some clamps I couldn't take the car out ! Tomorrow we will have the clamps, mount the front bumper and CAI and that's it. I've also replaced the flexible joint of the Milltek downpipe wich was leaking and we made a straight stainless connector between the upper water hoses to replace the plastic T wich was no longer needed ! Tomorrow everything will be done and there is no need for burn in cause we didn't touch the engine block this time. However, only after some logs and gearbox monitoring I will be able to say if the car will go to the next Hungaroring wich is next saturday !
PS : Seems I didn't mention it but I've entirely replaced the cylinder head with one that had low mileage and wasn't machined like mine (the machining on mine was of low quality so the valves didn't seal well on the seats wich might also have caused those idle oscillations)
