I'm building a 383 for my WS.6 and plan to use two GT35Rs. After I'm done with school and get established I plan on building a 427 with two PTE 6766s.

Curious why SNOOP's post with the video link got deleted...

For 1000rwhp cast or billet will be easy to do with that size. I would go BB if you can spring it. No worries about thrust assemblies when you start pushing it.

Yeah they are awesome. We have a customer running a pair of them, but you better have ALOT of room...lol. They are twice the size of standard 66mm units.

Pulling this back up been fitting the mock up block/trans in and really think that twins are going to be way more complicated due to the steering trying to snake a downpipe past so i make opt out and go with a single even though i did not give up just yet! But if i do what single would work best for my needs for the 427 build?

Old thread, but why are the BW's physically so big ? Does the larger volute actually make them any better ?
