with a few modifications its pretty easy to develope some decent power out of these cars. a engine management system, bigger injectors, intercooler, fuel pump and a few bits and pieces but the key is the right exhaust

The original Ford BA XR6 factory turbo assembly with cover removed

Move over image to see
inside the turbo housing notice how the waste opens

After careful consideration and what was available we decided [i was told] to make this dump pipe with a separate wastegate pipe. The dump has a small separator between the wastegate and the engine pipe to ensure perfect gas flow and minimal leakage between the waste gate pipe and the dump pipe

With this pipe we produced good results, 303kw @ wheels

the system on this car is 3 1/2" from the cat back and could flow to around 400kw @ wheels

The large body mufflers are straight through for maximum flow

With 4" single dump power increased to 321kw @ wheels

Dyno results

Twin dump 303kw @ wheels

Dyno results

4" dump 321.7kw @ wheels
