Turbo Manifold
Turbo Manifold
I have a Garret Airesearch T04 turbo with a split pulse exaust housing, I'm building a manifold for a E series falcon my question is do I need to segrigate the pipe's ie 3 pipes to each of the 2 inlets or will it work ok with 6 into 1

Re: Turbo Manifold
obviously the 2 lots of 3 is the optimum with running a split pulse housing
if it was me
if rear housing is on the smallish side for the application you can just run the 6 into 1 which will increase flow and lower backpressure
if the rear is on the big side id seperate them into the 2 lots and run them split pulse to give better boost response
id also use split pulse if the turbo should be right for the application
either way it will work you only have to worry about manifold design once you step up in the cam duration and overlap

Another question with a split pulse setup how would an external wastegate be plumbed? If I only gate one inlet port on the turbo would it bypass enough exahuast gas or would I need to run 2 wastegates?

Re: Turbo Manifold
do not only gate 1 port as that will lower TIP on those 3 cylinder which will make them run lean as they will flow more than the other 3 cylinders with higher backpressure
iv used twin wastegates on a rotary with excellent results
you could tuck the gate in close to the collector and take the wastegate off there 50/50 both banks
you will get a syphon effect through the gap but its still better than open collector
