T. Turbo is back

What’s with the twin wastegates? I know nothing about them but is one not enough?

Twin scroll turbo so one wastegate for each scroll on the turbo, with 2x exhaust ports feeding each side. In theory one large gate would work but thats how Nortech set it up.

It does spool quite fast for a low comp engine and large turbo, so overall it works decent. All in around 3800rpm from memory. Boost control is rock solid hits whatever level its set at, and holds it right to the 7800rpm rev limiter.

Thanks for the explanation. Makes sense now 👍
