Good on you. I use to have a gyrocopter with a turbo without a muffler, I find it acts like a muffler. Do you have twin turbos? It's going to make a nice foot heater that close to the panel.

No idea bout the other kits, but I thought most of them were body off.

I thought I was a bit mental with a turbo V8, but a turbo gyro takes the cake! hahaha

I'm probably taking the turbos off. I can't make them work vertically (they smoke excessively) and horizontally I can't make enough space to put them in a location that drains the oil back into the sump correctly.

Ive had a bit more time to play with the Cobra the last few days. I bit the bullet and removed the turbos after long contemplation. I dont think I could get them to stop leaking oil into the mufflers. I made a mini pipe to swap for the turbos out and if i can think of a way to stop them leaking them they can go back on..

Sorted out the ABS module comms issue, which also sorted the trans issue (the ZF auto uses speed and throttle position to work out gear position), so took it for a quick spin to see if the module is talking correctly, and if the traction control works correctly...

I can report that the traction control is perfect! As the engine comes on cam, it just slightly steps off line, a hint of torque control, grip returns, and BAM! More POWER! The trans is also really good, almost seemless shifting, worth the headache of wiring and the complication..

The engine note is just great, it is not in limp home, so its putting in full advance of the ignition. Theres a video, if you'd like the link, just PM me, as it may or may not have been legal to test it....

sorry, i haven't looked through the whole thread but a couple of questions about your turbo setup that could help, potentially.

Does the oil drain have enough fall into the sump? if not then you can use a diff oil/scavenge pump to pump it into the cam covers ,oil filler cap.
Switched from ign acc on and with a timer for 5 to ten seconds after switching off can draw remaining oil from the turbo (also does away with any need for a turbo timer)

Are you running a oil filter inline into the turbo, to suit the feed line? these as well as a low pressure (2psi) check valve can stop oil draining into the turbo once the engine is switched off, assuming you have a length of oil line falling into the turbo.

hopefully something i suggested can keep you on track to over 400kw atw.

see you on the other side....
