Just visited an aquaintance today with a rather tasty 3 door track car.
This has ALS but nothing like I have ever seen myself.

It has extra valves and pipework to inject fuel and air into the exhaust
manifold just before the exhaust housing inlet.

Has anyone ever seen this kind of set up before. I havent !

The engine is a T4 mountune conversion and fook me does it have no lag !!!
