For Canadian and metric market Supra MA-71 Turbo Cars



Hi Supra fans. I am sending this to you guys because I am always asked,

"what is the boost going to on my factory gauge"? Most of you may have

converted this over but I was not sure. Anyway here are the pressure

values in mm/hg x100 = psi for anybody who is interested





  51.71 mm/hg = 1 psi

103.43 mm/hg = 2 psi

155.14 mm/hg = 3 psi

206.86 mm/hg = 4 psi

258.57 mm/hg = 5 psi

310.29 mm/hg = 6 psi

400.00 mm/hg = 7.75 psi {Last numbers on your factory gauge "4" or 400}





Have fun boosting your Supra
