This photo shows the TA Performance SPX single-plane intake used during most of this month's testing. We did not employ the intake's cool-water passage under the plenum. The purple things in the Holley 750 are quick-adjust jet plates from Percy's High Performance. All our testing was with 91-octane gas from Rockett Brand. View Related Article
