Thoughts on exhaust housing size for a twin 66mm 347? I was shifting my old combo at around 6600 rpm with my 331 and single 76mm turbo. I currently have two Turbonetics 66mm turbos rated at approximately 750 hp each. The turbos came with .68 housings. I'm worried that the .68 housings might limit my shift point. Any experience with this? I'll try them and if it won't rev, I'll get .81 housings next year I suppose. I'm shooting for 1000 rwhp through my TH400 and 8 second 1/4 mile times with this combo.

I am using the same housings on my 363 and they work great
OK...Good News! I can't wait to see the difference in power delivery versus my old combo last year.

You will need a transbrake to hold the car while you build boost, but I was building 15# at 4200 rpm and could go as high as 17 at 5000.
