The best part of all this: The S55 runs the same intake manifold as the N55. Therefore this kit may be able to adapt to the S55 as well!!! This could be huge for us.

Steve: start working on a S55 LPFP upgrade?
We've just been waiting for the platform to reach the point that the upgrade was needed.

We already offer an E85 ceritified Stage 2 pump assembly for the F-series that BMS is running on their 435i. It should be good for about 600whp on 100% E85, obviously more at lower E concentrations.

We have not seen the F82 LPFP in person yet. On Realoem it looks the same as the F3X but obviously has a different part number. That stock pump is tiny so they may have just spec'd a different pump for the same assembly. If they did, we can get our Stage 2 out to you anytime. When the time comes to bump it up to a Stage 3...that'll take a lot more R&D since the design is completely different than that of the E-Series.

If you're ambitious, you could remove the access cover to the LPFP, snap a pic, and send it to us at'll give us a good idea.
