Testing the Magnuson TVS 2650 on a 2018 Trackhawk! Over 1000RWHP!

VMS Built 2018 Trackhawk – Magnuson TVS 2650 – 1000+ RWHP

This 2018 Trackhawk build is surely one-of-a-kind! We did a complete motor build, with forged rods/pistons, custom grind cam, billet main caps, billet Thitek heads, with the best drivetrain parts on the market. Topped off with the badass Magnuson Vengeance TVS-2650 supercharger, this Jeep flows so much air, its turning out far more than 1000+ RWHP on our Mustang Dyno! Thats impressive! Of course we have more than enough E85 fuel to feed this impressive 6.2L Hemi, with a complete Fore Innovations Triple Pump, Return Style Fuel System, and large 1300cc AUS Injectors. This is all custom tuned here at VMS (using HP Tuners) with custom ECM and TCM calibrations on the stock 8-Speed transmission and stock ECM to control it all. The driveline has been updated with some GForce1320 Engineering Axles and Driveshaft. There are some very minor suspension modifications, on this mostly stock platform. The Kooks headers and Exhaust system create quiet the growl with a perfect tone! While on our dyno, we did some testing for Magnuson Superchargers playing with pulley/cog ratios on the supercharger as well as VMP Performance testing their new 105mm throttle body, all which made impressive gains! To top it off, and add just a bit more power, we created a custom VMS Velocity Stack to suck in even more air! Check out more information below regarding the testing and numbers! Please note that the numbers shown are on the “lower” side of what this Trackhawk is actually putting down and what its capable of because the owner is a local Grudge Racer that will be at the track on a regular basis with this beast!

Dyno Results (5th Gear Pull, SAFE!)

With a good, safe, “base tune” loaded into our 2018 VMS Built Trackhawk, we did a baseline, 5th gear pull with the stock throttle body. We then swapped in the VMP 105mm throttle body (bolted it right on with no modifications), waited for temps to match the previous pull and did the same 5th gear pull, with the same tune (no changes at all were made!). You can see the immediate gains! Not only is the throttle response way better (you can feel it on the dyno), but we instantly gained 38rwhp at peak and brought the overall RWHP AVERAGE from 831 to 853. We also gained 5rwtq but more importantly brought the RWTQ AVERAGE up from 756 to 775! We love peak numbers, but races are won when the overall curve is greater! As you can see from the graphs below, the area under the curves for the 105mm TB (solid line) is far greater than the stock TB (dotted line). Not only that, you can see that the stock TB was a choke at high RPMs! With the stock TB, you can see the BOOST clearly hitting peak early in the run and then falling as you climb in RPMs. With the 105mm TB, you see boost hit and continue to climb as you get higher in RPM! No boost drop! In further testing, when we built a custom VMS Velocity stack (removed CAI, designed tube, and built in a bell-mouth the boost climbs ever HIGHER and gains are far over 1000RWHP!!!
