454 S480 turbo recommendations and expectations

[Jonathon Wolff]

hey I’m wondering how much hp a 454 with AFR 265cc aluminum heads with a .547 lift hydraulic roller cam and a single S480 turbo with a 80mm compressor wheel and 96mm exhaust side with 1.32A/R and a t6 flange would produce and how fast it would spool on the drag strip, also I have heard people recommend a 88mm compressor wheel and 106mm exhaust side turbo for the 454, what would y’all recommend?

That is above my pay grade so, I would have to do about 4 pages of calculations to figure that out.

Richard holdener did a test with one on the dyno so could give you an idea.
