Cork Sports Cat Back - OrangeVirus Tune Rafael Answer my EMAILS!
What's that in the tailpipe? Exhaust silencer?
And why is the torque so low on the last pic?
Cork Sports Cat Back Facts
- It is a beautiful piece of engineering design, materials and perfect fit.
- The shipping and packing was first class.
- The support from CortSport's team was prompt and professional.
- The tips looks great on the back of the CX9.
- The CorkSport exhaust is tuned too loud for my liking. Cold start was even more unbearable due to Mazda post start revving the engine to 1500 RPMs for 20 seconds.
- I currently have three other modded\tuned cars. The CX9 with the exhaust was louder than my Audi S8 with 723HP/Downpipes.
- So I did not want to get rid of the free flowing design because I am working with OrangeVirus on tuning the 2.5T. Stay tuned OrangeVirus is currently failing in this request.
- In the pictures you can see , I also used the CorkSport intake and inlet tube all at the same time.
Solution to making the CorkSport more inline with my tastes.
- Using a iphone app to measure DBs. I lowered the decibels about 15 to 20.
- Two Patriot Exhaust H3844 Side Tube Muffler Insert as seen in picture.
- Noico 80 mil 36 sqft car Sound deadening mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening
- Installation of 12-15 pounds of mat took 5 hours. Pictures show I disassembled the back of car and removed the third row to install the mat.
- SHOCKING. The 2019 has a lot more sound insulation compared to previous years. When you disassemble the car the 2019 was still a TIN can. Almost no insulation near the exhaust area.
- I installed the mat everywhere where bare metal was exposed. This helped reduce the residence and vibration about 10 DB.
- The second change was to insert the muffler inserts in both of the tips. They were a perfect fit. I used some steel wool to make a friction tight fit. This really helped the cold start noise.
- I achieved a decent sound level and look after these two mods.
Torque\HP Charts:
- The first charts show four pulls with the three mods (Weather 50 degrees, Exhaust, Intake and Inlet Tube).
- I have tuned over ten cars over the last 20 years. I consider this a hobby.
- Results:
- Car has a slight seat of the pants increase in acceleration. Highway speeds also feel a faster reaction when you accelerate hard.
- Facts:
- DYNO numbers almost show limited gains to factory numbers. I only run super 93 octane.
- Calculating a 17% loss the horsepower would be 212/.83 = 255 HP
- Calculating a 17% loss to torque would be 277/.83 = 334 LBS
- Analysis:
- Torque has biggest gain because CPU dumps all the boost when you get to 6000 RPM. So at 3500 or in sports mode you hit the torque sweet spot.
- Horsepower is limited around 4000 RPMs and the CPU just dumps boost like a freight train. ONLY a cpu tune can help.
- Summary:
- If you install all three mods you will enjoy about a 10 percent gain in a usable torque range. Horsepower is a meaningless gain.
Tuning OrangeVirus:
- I spent over a one year period, $745 and over 60 hours of my labor with OrangeVirus. I used my 2017 CX9 signature as test vehicle for a CPU tune.
- I installed over 12 different maps and ran multiple test runs. I supplied output of each run to OrangeVirus so they can analyze the engine levels.
- The communication was very difficult over the the 12+ months. They never shared what the changes were in each new map. So after 18 months of work I had a tune but no information on what OrangeVirus was modified.
- In 2019, I changed to 2019 CX9 GT and have been trying for 6 months to get the tune moved from the 2017 to the 2019.
- OrangeVirus agreed to move the tune for an additional $150. They took my PayPal payment but up to now OrangeVirus has FAILED to help me get the tune on the 2019.
- It is VERY difficult to get a response from them. Even after I gave them over a year of testing their product.
THE LAST IMAGE is from OrangeVirus new claim they can tune a 2.5 turbo engine. YES the torque is 25% less than factory? WTF? The horsepower shows 225 so its 5% higher than stock.
ORANGEVIRUS answer my emails after taking my money!!!!
