TT sizing for 427
Looking for good a good TT size that won't have that much lag, and won't run out of breath up top for a 427.

I would at least go with 7675's, they spooled up quick on a 364 and can easily make north of 1500hp.

how much over 1400? I know someone that runs 6870s and makes a little above 1400whp in a vette. spools fast and doesnt run out of breath

I would say a 67mm compressor minimum to hit your goals - I'm running 72mm Borgs that still spool nicely and make solid power.

I saw your build. Trying to stay within the stealth look. I like my AC. I know the engine bay will limit what size turbos I get. Badass build tho.

Mid-mount or fender mount is probably the best way to achieve your goals. Space is a little tighter in that area, but should be able to fit a 67+mm turbo in that area. Comp oilless turbos work pretty well when space is tight and make solid power.

I think 6870 is the biggest turbo you can fit if you're trying to go mid mount with something like the Huron Speed C5 hotside kit.

Maybe dump the dry sump for space.
