When do you get full boost, Albert? Way past 4K RPM I would think

MrShades, what size Garretts do you have on your TT setup? T3's?
4300 RPM = 0.5 bar of boost, still stock internal. Too big.... but drives pretty well...

I have 2x GT 35R turbocharger,2x wastegate, intercooler for twin turbo, sitting in the shop.
One week I got nothing to do I cut the header and put everythings on 1989 930. I live 1 mile up on mountain in Taiwan, twin GT-35R turbo is not that bad.....Ball bearing turbocharger spinning well at low end, light pressure.

My plan is getting LN engineering 3.4 L cylinder and pistons, GT-2 EVO cam, race valve spring, twin plug, Pauter rods, raceware head studs. up the engine redline to 8000RPM.
1975 914, 1988 944 turbo S sold.
1986 944 turbo resleeve 2.7, DTA S-60 PRO.
1986 911 Carrera with 965 turbo motor, DTA S-80 PRO.
1989 930 EFI, DTA, Carrera intake, twinturbo,2x GT-35R.
1991 964 convertible, wide body conversion.
