Bruce2009KR Posted August 7, 2017 Report Share Posted August 7, 2017 So, life is too short and I've read so many positive things about the TVS addition to the KR that I'm close to pulling the trigger. For those who have actually done it, help me with the following: 1. I'm looking at the VMP Gen 2 TVS and the fellow there recommended this:VMP 07-14 SHELBY GT500 2.3L TVS SUPERCHARGER - 720+ HP KIT He also recommended a set of 8, 56 lb fuel injectors ($299) and a dual plug-n-play fuel pump 40 Amp Voltage booster ($549). I am a bit ignorant on the discussion of boost and pulley. I want to be conservative and don't want to encounter problems. Here's some of the description: The VMP TVS 700 HP Kit Contains: VMP TVS GEN II-R 2.3L Supercharger VMP Twin Jet 67mm throttle body Pulley of your choice (2.4", 2.5", 2.6" or 2.8") 1 year warranty Unlimited technical and racer support VMP Custom Calibrations by Justin Starkey additional starting as low as $199.00 (No charge to existing VMP Tuning calibration customers) May be used with 10% or 15% OD lower crank pulley for 17-23psi. Boost chart (at sea level) with included supercharger pulleys vs crank pulley/balancer size: SC Pulley Stock Balancer 10% OD Balancer 15% OD Balancer 2.40" 18psi 20-21psi 21-23psi 2.50" 17psi 18-19psi 20-21psi 2.60" 16psi 16-17psi 18-19psi 2.80" 14-15psi Step up to 2.60" recommended Step up to 2.60" recommended Boost is an estimate based on stock exhaust, subtract 1psi for off-road exhaust or longtube headers. Max recommended boost at sea level is 16-17psi before fuel upgrades are required on 07-10 cars. If you are significantly above sea level you can run a more agressive pulley combination to make up for the altitude. Most 07-09 cars will baseline at 420-460RWHP stock and 10-12 cars at 460-480RWHP stock. VMP TVS adds 170-220RWHP over stock, more depending on modifications. I'm open to suggestions and from what I understand, the KR does not need much other than the TVS itself so do you recommend the extras they're suggesting? Lastly, I fully realize suspension work is the next logical step should I perform this swap! Thanks in advance, Bruce Quote Link to comment Share on other sites More sharing options...
