I have a 2013 Brembo GT manual that I have driven and tracked since new. In 2021 I had a timing chain get loose and hurt motor while running at Barber (car had over 100,000 miles and several hundred road course laps). Installed a Frankenstein 3-2-1 long block that included L&M Gen 1 intake / exhaust cams and 2018 intake. I have stock exhaust manifolds and now have GT500 mufflers. Car made 426 rwhp @ 6900 rpm on a conservative tune at Palm Beach Dyno (and made 441 @7150 on E85) with stock GT mufflers. I recently bought a first generation Cobra Jet intake and was planning on getting a JLT intake and VMP twin 69mm throttle body. What is a realistic expectation for horsepower gains and potential torque loss?
