NOW AVAILABLE! This Nitrous system has been thoroughly developed and tested over the last year on multiple cars throughout the country. It is optimized for max power and longevity of your stock engine. The kit is designed to support up to 200 wheel horsepower. Unfortunately the limitations of this kit are the stock connecting rods in the stock engine and the fuel system. Hence the fact that our complete direct port nitrous system is being sold with a pre programmed and sealed nitrous controller (full throttle and window switch) by JHM and only 1 set of jets. This setup is designed to work best with a stock engine and stock fuel system. So far we have safely produced 70 to 80whp (100 plus at the crank) and 70 to 80wtq (100 plus at the crank) gains with several cars. Some JHM Header equipped cars have created 100wtq plus. We have also performed a lot of dragstrip testing and have seen as high as .5 second ET and 7mph gains with 2 different cars at 2 different tracks with a best of 12.03 @ 116mph (customer in Indiana reported this ET). With our JHM in house test car we went 12.70 @ 111mph all motor then 12.29 @ 117mph with the nitrous. This was a 6 mph and almost .5 second ET change, in the video you can tell we drove the car a lot harder in the all motor pass and got a better 60ft. So our estimates are conservative as always. See the video below.

If you are existing JHM tuning customer a free update is supplied, if you have a stock or non-JHM tune a $350 option is required and must be selected below) 1 x pair of JHM 4.2l V8 direct port nitrous plates, 1 x JHM programmed nitrous controller (full throttle / RPM window switch), 1 x JHM jet pack, 1 x JHM fuel pressure stabilizer, 1 x 10lb Nitrous bottle (shipped empty) 8 x JHM spec Bosch spark plugs for nitrous, 1 x Nitrous Solenoid, 1 x Fuel Solenoid, 1 x Purge Kit, 1 x Bottle Heater Kit, 1 x Nitrous filter, 1 x NHRA spec bottle blow down tune and all hoses, lines, wires, switches and hardware necessary to perform the installation. The JHM Nitrous System is an Eaton M90 supercharger stomper as well. Nitrous makes more torque longer and more HP earlier as well as longer so even with similar peak HP and Torque numbers it will dominate a supercharger kit in any gear. Check out this video on YouTube of it in action vs. an Eaton M90 supercharged car. -> HERE
