PTF Sponsored Track Car – Custom BMW 135i N54
Posted on 06 June 2013
We recently received a call from an east coast shop owner who does some of the cleanest work I have ever seen. He runs a full race shop and has a 2008 135i with only 5000 miles on it. All 5000 miles are track miles as the car has never been registered as a car to run on the street. He is running RB turbos and full supporting bolt ons and tracks the car on 93 octane. We have decided to join him and support his tuning needs for the upcoming track seasons. After hitting the dyno today we have dialed the car in a bit more and focused on a tune for long / high heat and intense track sessions. 3+ hours on a road course tends to take its toll on a car and without the proper tuning and cooling it could cause problems. Between the tune we put together and the custom built parts on the car – this is going to be a very fun partnership.
Without the specific components, additional cooling modifications, and custom built race parts that he fabricated in his shop – this car would not run as well as it does. The car put out impressive numbers on the dyno today. It made about 443whp and 432wtq and never touched over 18.09 psi (set to hit and hold about 17.5psi but flirted with 18.09 for about 150rpms lol). We have a few more revisions to get everything dialed in perfectly. This was a third gear pull on the dyno as we ran out of time to start doing some 4th gear tuning. We will probably keep the car well under 18psi even at high load.
On to the impressive pictures!
