Nice one Ash, looking forward to that ride with the new setup, you may convert me back to a large tubby;)

Ive not seen a setup like that before with twin wastegates on a single.

 

Yeah, the chatter from them is awesome, i feel like putting them back on. :D

Sorry if I've not kept up but what did you have on there before Ash?

 

Whats the benefit of twin wastesgates?

 

None I'd imagine, if anything it's going to make boost control tricky - any tiny imbalance on the wastegate (they are not exactly carefully matched things) and the pulse differences I would think make it difficult to properly control boost

The only real reason for two wastegates would be increased flow to stop boost creep when using large turbos, as already mentioned a single large wastegate would be much easier to manage.

 

You could use a simple open closed solenoid with two wastegates to give you switchable boost pressure using two different springs but with most modern boost controllers and ECUs its not really worth it.

Its the toyota ecu with a tectom board in, it was big in japan

but the sofware was a fortune.

Andy at AMT has it, it runs sweet as a nut fueling was spot on.

It runs closed low down which is smooth then swaps to map, on boost no splutter, miss or anything.
