I'm still in the hunt here. Not using the ESS kit, I'm going to fab my own system.
I'm finishing up the N54 intake manifold and TB install and now seems to be a good time to install check valve(s) to keep the boost out of the crank case. I retained the check valve from the N54 TB to the fuel tank vent. It seems like one is also needed in the PCV line between manifold and valve cover. Any others?

Or do I need to re-route this line to the intake upstream of the SC and plug the port in the manifold?

I found the answer here in case anyone else is looking:
https://www.e90post.com/forums/showt...1143622&page=3 Also ESS doesn't list the N52 kit anymore, but it seems you can buy the parts: https://esstuning.com/n52-vt/

I've had no issues with the n54 crankhub, but if you're thinking of swapping to that I don't think it would help keep the crankbolt coming loose. What are you torquing it to? Double-check if I'm right but I believe it's 100nm+360 degrees with no thread locker, but I've seen some people say to put oil on the threads.

Currently I'm on full e85, or I guess e70 since that's what it ends up testing at, but I'm planning on running the water to air manifold that stagefp should be releasing soon. |

Tis says 100Nm + 360 degrees turn and lightly lubricate the thread. We did just that, added blue Permatex thread locker and the crankshaft bolt still came loose. Then we installed a new bolt, but no longer lubricated it with oil, but only with thread locker. Even the OEM washer was installed from N54 and the bolt still came off. I do not know what to do. |

At minus 10 Celsius, my boost gauge showed 13 psi. 6900RPM Now it's plus 8 Celsius outside and my boost sensor shows a maximum boost of 11.5 -12 psi. 6800RPM In the coming days, I will also install an IAT sensor in the intake manifold. I also have a WMI injector installed in front of the throttle body. 22RPD recommended adding a second WMI injector, upstream of the supercharger. And measure IAT temperature Last edited by Igor.v_a; 03-28-2024 at 02:53 AM.. |

I had that same exact crankbolt capture, and that is why all my crank pulley bolts broke off. I've known of at least one person who tried it and had the same thing happen as me. I would highly advise against it since with it you risk having to replace your crankhub. I'm not sure what the solution is but I definitely wouldn't run the crankbolt capture.

WOT This is probably the fourth time this has happened to me. How did you overcome this problem, what exactly did you do to prevent the crankshaft bolt from coming off? I don't understand at all why this bolt comes loose. After all, the N54 engine has much more torque than ours. And the N54 is doing well. |

The N54 eats crank bolts as well. Just usually at power levels a little bit less than double.

A belt that is too short creates a strong load on the crankshaft damper. What article number (size) of belts do you have on the 80mm pulley? |

I don't know the length of it since It came from 22rpd as part of the upgrade kit but it's called "Gates K060997HD FleetRunner Micro-V Serpentine Drive Belt"

As far as I can tell it isn't slipping with the 80mm pulley, but the tensioner is just about maxed out. I also forgot to mention that I'm also running a larger idler pulley on the supercharger which I also got from 22rpd

M3 injectors maxed.
22 rpd got back with me after some data logs and apparently the s65 injectors are maxed out.
Setup is currently S/c G1 110 mm pulley N54 manifold Headers. Was surprised I was making enough to max the injectors. |

First startup will be tonight. Hopefully!
I'll post full details in my thread once it's up and running. Thanks for everyone's help here.

C38-71. Flows up to 660hp worth of air. I'm starting with the largest pulley and expecting 5ish psi. 22RPD said to do some gentle driving and send them some logs before going WOT. I'll downsize the pulley as the tune/IC/fuel allows.

Does the StageFP tune use the MAF?
