Well I got a call last night that a shop in Kamloops (Enhanced Autoworks) made 580hp with 30psi and a 70 shot of nitrous. I went down there today and they were sorting out some boost problems and with 4 of us in the hatch to prevent wheelspin the engine made 538hp without spray. They were going to do a run with nitrous but the head lifted (probably due to the load and stock head bolts) I think that the engine would’ve made 600hp. I’ll post pictures of the car once I pull them off my camera. I think that they’ll have video up soon. http://www.enhancedautoworks.com
