Any Twin Scroll experiences?
I'll be starting the installation of a Twin Scroll T4 Borg Warner internal wastegate on my '97 NA. The idea started with the excellent behavior of the BW Twin Scroll in my Mini Cooper JCW which has no lag and is very small.
Anybody here has installed a twin scroll on a non-VVT engine and if so how did it come out? Having talked with the main players in the turbo kit manufacturing area I didn't find anybody interested in prototyping a kit for a 20+ year old engine. So I'm left to my own resources, something not foreign to me going back to the first Ford Cardinal-Saab V4 turbo which I co-authored a very long time ago. Any ideas will be much appreciated. |

Twin scroll, internal gate BW. This better be an efr. Custom manifold is going to be the way to go.
|
Yes, maybe the EFR 6258. Thinking about positioning it downstream.

I think with all the extra bends required to get the runners to the right spot on the collector at all the same length the tiny advantage you'd gain from being twinscroll would be lost in head loss.

But you lose heat energy by positioning it further away.
|
And you cant really do a twin scroll from far away.

^ and ^^ Not if you know how to increase the heat and maximize flow/pressure in the manifold. Just completed a test with excellent results.
Good thoughts I'd like to pursue but I better stop posting for today or I might get nuked as a noob. |

but seeing you make 3 threads within an hour none of which had much if any useful info or content definitely catches people's eye, considering your join date. |
Isn't Fae running a twinscroll BORGWARNER S366? He's pretty much our resident ALLOFIT massively oversized turbo guy, you might want to look him up, I'm sure he can drop some knowledge on you ;)

The word "downstream" concerns me.
|
I'm surprised its taken this long before someone pointed that out.
