225 turbo headers

Very nice! Exactly my point.

Both Tom Wolfe and Ryan Peterson have 233 cubic inch 225 motors that run one 4bbl Holley, turbo-boosted, on gasoline and both make about 500 horsepower.

Can you show me an EFI slant six, running on gasoline that makes significantly more horsepower than that?

Just askin'...:glasses7:
