F20c TTS Supercharge - Lack of Power
I have lost power on my F20c with TTS Supercharger running on Emerald k6
it runs fine on idle and when driving under power, just feels slow in anger.
i have
- checked all pipes and sprayed with soapy water
- checked map sensor on laptop
- checked tps sensor on laptop
- removed exhaust and changed all the gaskets as when it lost power it blew a joint in the box to the manifold
- have changed the Vpower fuel in it
- removed dump valve and blanked off pipework and vaccum line to ensure thats no leaking
I have ordered a leak detector to bolt onto the turbo to test intake pipework
it has no o2 or lamda sensor, no knock sensor with the emerald. (im not touching sensors or the map as mapped my emerald and it ran sweet as a nut).
Any other ideas to eliminate items.

Enable logging on the K6, set it to something like over 25% throttle opening and watch MAP and fuelling, if it’s making decent boost you should see
plenty of fuel being poured in…
Pity you do not have a lambda sensor, it would be worth fitting one.

Have you tried removing the intake hose and seeing if the impeller rotates without the engine running? This would rule out a snapped impeller shaft,
not uncommon on a Rotrex unit.
If the impeller shaft is damaged have a chat with UKSuperchargerRepairs on Facebook, he has repaired and upgraded one for me.

Does it need to have a laptop plugged in when driving for this?
Hopefully easy to find the option!

Laptop needs to be plugged in, with logging enabled it will then create a file with an option to save as an excel document you can then graph the
results easily

Long story short, i took it to a dyno. Was making 176bhp and i unplugged the vtech solinoid and it made 146bhp so that was working. It making full
boost pressure and sounded well.
got it off the dyno and came to the conclusion engine prop fried.
The mechanic held the link pipe and found number 3 wasnt getting hot. we tried one last thing of swapping the coil packs around and . . . it was the
coilpacks.
Borrowed a coilpack and loaded it back on the dyno. Its back upto full power after we had to strap it down to the dyno again because it kept spinning
its tyres 
Feel like an idiot. . . but a happy idiot!
Guy said he was amazed by how normal it sounded on 3 cylinders.
