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?

Are you mounting the twins upfront and in what car?

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