whats a merge collector? is it like equal length pipes?
will be mating it to a t3/t4
to simply explain it
its a dividing part in the neck of the manifold, so it helps distribute the air through the manifold evenly, ensuring a similar level of air flows down each collector and into the head
distributing the air evenly is key to aid quicker spooling of the turbo, but most importantly, once the turbo is spooled, to then allow it to sustain boost as much as possible with the air flowing evenly and quickly throughout the manifold which is aided by the collector
I hope that helps
If I was you, I would speak to Bill Brockbank at
www.badger5.co.uk.
he will best be able to answer your question on which manifold is best to suit you design or application of turbo, but please for the love of god, dont buy that manifold, it looks shite
which company are selling that manifold by the way?
