Is This The End For Port Injection? | BMW N54 HPFP Overdrive Kit!
In this video I talk about the new HPFP overdrive kit available from Spool Performance! I got my hands on one of the development pieces and will be one of their beta testers. I show you how to install this kit along with their new 10 micron fuel filter kit. For anyone wondering I met with the owner of Spool in person and got their blessing to go ahead and release this video even though it's still in development. Typically as you get past about 450 WHP you would run out of fuel on your N54. You have two choices when it comes to adding additional fuel. Firstly you can add port injection, secondly you can overdrive your HPFP. Port injection can work well but you need to have a really high end controller to fire the injectors sequentially and ideally have it communicate with the ECU to know when to stop spraying. You can use MHD to deactivate coils during a misfire but if there is enough built up heat in the cylinder you could still have combustion. It seems like manual cars are more susceptible to engine damage from port injection. By over driving your HPFP you're meeting the required fuel demand and allowing the stock ECU to be in fuel control to intervene appropriately during a misfire. I'm excited to try this kit out and see how much power my car can make on E50 with Stage 2+ upgraded turbos. Here is a link to the company that is offering the products show in this video (not an affiliate link): http://www.spoolperformance.us/ Eventually they will post the HPFP upgrade kit on their website along with the filter. I'll be following up with a dyno video and show you guys my fuel pressure before an after the upgrade. Thanks for watching! If this is the first video you're seeing of mine consider subscribing.
