On3 Cobra Forward Facing Turbo System
Details
On 3 Performance is proud to release the newest 2nd generation Mustang 4v Mustang Cobra turbo system with forward facing headers. After almost a year of developing this new On3 turbo kit, they are stocked and ready to start shipping. On the same boost level they ran with the previous 1st generation kit, On 3 picked up almost 30rwhp/50ft. lbs. mid-range. Most of this is due to the new design and being able to spool the turbo quicker. On 5psi, we are making full boost in the upper 2000rpm range, that’s around 700-800rpm quicker than before. There is nothing like turbocharged power on your modular 4.6 Mustang, bolt on and double the factory horsepower. With this kit they have had customers go deep into the 11’s. Looks like we might see some 10 second passes with the new 2nd generation kit on a stock bottom end 4v car. You will have no problem trapping 120+ mph, they are trapping almost 121mph with the shop 2002 2v GT.
By designing a header that comes directly forward they were able to eliminate about 4'+ of tubing pre-turbo. This also allowed them to route the tubing for the intercooler differently as well as the downpipe. This provided improved ground clearance. Even though it was never an issue, why not improve it if possible? In order to drop weight with the kit they also went to aluminum intercooler tubing over the stainless, this lost almost 15lbs from the 1st generation kit. This is also a shorter, and more direct path which also has shown benefits. In addition to the turbo kit they added a few other features to make the install easier and prevent issues down the road. On 3 also designed a laser cut intercooler bracket kit that is manufactured just down the road from their shop. While they were at it they also had a turbo support cut that allows the weight of the turbo system to be tied back to the engine. This way the weight of the pre-turbo/turbo is supported by the bracket instead of the actual tubing.
Each of the On 3 Performance turbo systems come with their 70mm turbocharger which is rated up to 700hp. Currently the 2v shop car has around 20,000 miles and 4 years of daily driving year-round. They have proven the turbos durability over time, and if maintained and installed correctly its unbeatable for the money. The turbo is proving to stand up to the test of time and they could not be happier with the results it has provided.
Each header is constructed of 3mm wall mild steel which they have been proving the durability of on daily driven cars. From the headers to the turbo is 304 stainless all the way from the turbo back. On 3 also went to a slip fit downpipe instead of v-bands. This allows for more adjustment due to the lap bands which is necessary for the application.
There is some movement in the way the turbo can sit so this allows the installer to be able to get a better fit. The cold side now is made from aluminum instead of the stainless to drop weight. This will also help with dissipating heat, and will allow for slightly cooler IAT’s. Each tube on cold side is bead rolled and uses t-bolt clamps for a perfect seal and to prevent blowing a coupler off under boost.
Key Features:
– Perfect fit for AUTOMATIC transmissions
– Retains factory accessories – Air conditioning and Power steering
– Quicker spooling
– Forward facing turbo headers
– Less exhaust connections pre-turbo
– Turbo support bracket/Intercooler brackets included
- Better fit on the SN body cars to clear coil packs
– More simple design to eliminate tubing
– Easier to install and adjust the kit
– Maximum ground clearance
On 3 Performance has shop cars with each of their kits on them, and the mod motors respond to boost extremely well. They are very reliable, and drivability doesn’t get much better. It’s a good feeling on a 90 degree day to put the windows up, and crank the air conditioning to full blast. Whether sitting in traffic, or cruising, no heat issues come into play and the car still drives like stock.
Over the time On 3 Performance has sold their turbo systems, they have customers who are customers producing close to 800rwhp on stock heads and cams with this turbo system and 76mm upgraded turbo. A quick YouTube search will net you quite a few of these customers and physically see the cars in action.
In order to run the turbo system, you will need to run the On 3 Performance turbo tubular suspension kit. Also there will be several upgrades you will need to make for fuel delivery and air which are available in the otions.
