As always, some kick ass work going on here. I do have a few questions. Not clear on the tube in the plenum. Is the outside air coming into the plenum from the bottom and therefore going through the tube first in an effort to evenly fill the plenum and therefore evenly supply air to every cylinder or is the tube performing some other function? Are you getting rid of the AFM or MAF and running an Alpha N setup (sorry if you already said this earlier)?

Also, you may have already answered this but I forgot, does the early Mk60 run completely standalone or does it need to integrate with the Emtron to perform properly?

Thanks again for sharing, I love following the progress.

Eric
Thank you for the compliments!

The plenum isn't designed completely yet but I have included a hand drawn pic of the layout to give a better idea. The back portion of the airbox will need to be made to fit the front half, and it will feed the "manifold" that will hopefully distribute air more equally. I will run the engine on Crank, Cam , MAP and Lambda. The intake size would ideally be 6"-7" in diameter and taper down to increase velocity.

MK60: Can run alone with the correct Hookups and harness for ABS. I will be installing a yaw sensor and and steering angle sensor and will be able to run DSC and traction control through the Emtron along with the MK60.

It looks like on the scetch that u are planning to use the oem panel filter box. If so U may/will need some sort of flex as the engine moves under acceleration.

Correct.. I am remaking the foam from the airbox which will change on the engine side to the plenum, hopefully this week. Once everything is mocked up I will know where I need create a playable connection.

Quick update

Post by TBM » Thu Jan 17, 2019 4:54 am

I needed a Crank position sensor. I was encouraged to buy one from VAC as they have a kit for the S14. I wanted something that fit the OEM bracket that is also adjustable. The VAC unit is +$200 use for the sensor, as the kit is made for the S14 it wont work on the S38 as far as I know..

I found that ZF (formerly Cherry) makes the same hall sensor without the terminated end (which I don't need anyway) and it works just like I wanted it to and it only cost $24!

Looking good, do you have a part number for that? Also, are you going to a later S38 harmonic balancer, or something else?

Thanks,

Eric

This is the part I used:

I am trying to go a different harmonic balancer that will fit on the flywheel but if I stay on the front piece I am trying to go for a piece called the Sterling Rattler from a company called Vibration free in the UK.

Crank position sensor retainer

Post by TBM » Mon Jan 21, 2019 4:37 am

The OEM bracket is working out but I needed to make sure that the Sensor can be held in place and be adjusted. I designed a piece that will mount on the top of the bracket and be held by a screw into the OEM piece.
