Mikes immaculate 2018 Jeep Trackhawk is ready to be shipped back to Gold Coast QLD along with his DT ram etorque we fitted a Harrop supercharger too.

After making 1000awhp on 98 we flexed it over to E85 and made 1223awhp / 912awkws 1488nm of torque 23psi boost

If you don’t think a Kong supercharger is for you then this 3L direct connection is the next best thing as I am quite impressed with the results from a OEM blower considering this engine build is a very basic 426ci

Mikes immaculate Jeep Trackhawk with only 9,500kms on the clock was sent down from Gold Coast QLD to improve the build for him.

Already fitted with a built 426ci and 2.7 demon blower it made 844awhp 20psi boost on 98.

We have now added the following…

✅ 3L direct connection supercharger with SDG ported snout and 108mm TB
✅ Built Stage 2 SS Dontex Performance built transmission (2 year warranty)
✅ Built Stage 2 Transfer case (2 year warranty)
✅ ATI 10% lower balancer
✅ Dontex Performance True Flex Fuel

It made 993awhp / 740awkws 1158nm of torque 21psi boost pump 98.

Now time to flex over to E85 and send it to the moon and see where this direct connection supercharger taps out.

For those who chose the old school over the new school in the last post here is 1100 reasons why I would chose the demon 170 any day of the week. 🔥

This car came to us completely stock with a full exhaust and made 828rwhp out of the box on pump 98 fuel.

Now fitted with our Dontex Performance custom D170 Camshaft package this made a solid 1101rwhp / 821rwkws 1338nm of torque 22psi boost on e85.

We are still using the factory OEM flex fuel system and believe it or not we still have the factory D170 injectors in it and it made 994rwhp / 731rwhp 1068nm of torque pump 98 22psi boost

This thing is a complete handful on the street even with the Mickey Thompson ET R 315/50R17 but still drives like a factory D170 while cruising with the nice old school idle chop it deserves

Contact us today if you want more out of your D170 from the specialist that now your D170 better than anyone else in Australia

Another 🇦🇺 Australian Record laid down last night for Dontex Performance at Peter Pisalidis

Mitch’s first time out in his Twin Turbo Jeep SRT 6.4 with a 10.45 @ 216kmh / 134mph and a lazy 1.8 60ft

We took some solid data away to keep working on this car achieving a 9 second pass.

Mitch also ended up in the final eliminations of roll racing with a trap speed of 218kmh.

✅ Dontex custom built 6.4 engine
✅ Hellion 62/62mm turbos with IWG
✅ Dontex stage 2 Transmission
✅ sipple speed hi stall
✅ plazmaman intake manifold

This build is a very basic set up on 18psi boost and is the ultimate sleeper 🤫

It seems Rams are in season here at Dontex Performance!

Currently getting our token 6.4 swap is this high kilometre DS 1500, which has suffered a grenading failed lifter and two cracked exhaust manifolds.

Now receiving a fresh 6.4 BGE and Manta Reproduction header replacements this Ram will feel like new once we are done here
