Based on what on heard from PBracing the Cold air intake i have might not work so i'm buying their carbon intake solution in case. The price of the kit for the supercharger, oil coolers, lighter flywheel and racing clutch including the tune will be around 12k. I think i'll be having Allen work on my car. They just recently left mohulland motorsports and started their own shop. They have a great reputation in the business and have done more projects on evora's than anybody else.
Regarding the dyno , last time i had the car on dyno it was making 276whp with all my mods. I'm thinking that my car will be making somewhere close to 425 since i have some other mods and complete free flow exhaust system.
