Prior to hanging my engine I would like to ensure I've planned/accounted 

for all of the holes that need to be made/placed in the firewall. So for 

those of you who have already crossed this bridge......



1. What ADDITIONAL holes did you provide beyond those already called out 

for in the plans?

2. What advice/suggestions do you have for the placement/location of 

those holes?

3. Did you fireprotect those additional holes? How?



(I'm installing a full engine monitoring system and know I need to 

provide thru holes for CHT/EGT)

THANKS for any help

Deems,

  

 Think you have to do this one yourself based on what you are putting in your bird.  I'd sit down with a clean sheet of paper and start listing everything that will have to break the firewall.

  

 Some things you can run thru same hole (like the engine monitor wires, fuel flow, fuel pressure, oil pressure, etc).

  

 Then there are others like the battery cables, cables for throttle, etc.

  

 After all was said and done, I ended up having to drill yet another one for the cable I installed to fix the tunnel heat problem......

  

 I'd start that list, then sit on it for a while while you think through all of your connections.

Deems,

I have two extra holes for all wiring using fire-proof 36-pin (I think) 

plugs installed near the hole for the MAP hose.  I can't recommend to buy 

the plugs where I bought mine with good conscience but I'm sure they are 

available elsewhere.

Below is a list of what I think is going to go through my firewall.  The 

list is probably incomplete and with some questions so any guidance from 

the list would be helpful.



Engine sensors will all go through a 1"  stainless steel firewall 

penetration from EPM.AV corp <http://www.epm-avcorp.com/tubeseal.html>.  

Most seem to be putting this penetration in the upper right corner (like 

Tim).  I would like to mount it just to the right of center.  Any 

concerns with this location?

The wires through this penetration would be

EGT

CHT

oil pressure

oil temp

fuel pressure

rpm

manifiol pressure



Electrical power

Main power feed Super 2 CCA fatwire 

<http://www.periheliondesign.com/fatwires.htm> will go through the 

firewall per vans location mid left

Starter contactor per vans location

Current limiter and loadmeter shunt located on oil cooler housing

electric to the main bus and e bus penetration near the starter contactor

Magneto wires, not sure where they will penetrate.  Not sure what can be 

combined with these wires.  Any guidance?



Cable penetrations through Stainless Steel eye balls.

Prop

Throttle

mixture

Fuel purge valve (airflow performance FM-200 fuel injection)

Alternate air - How does the alternate air actuate?  Is it included with 

the FWF kit?

4 penetrations can be arranged where vans has the bushings located in a 

diamond shaped arrangement.  Scott has some photos on his site.  Not 

sure where I would locate the 5th if there is even a 5th.



Anything missing?

To add to this question - For those who have completed the engine wiring,

would you recommend having all of the engine monitor wiring go through one

hole (if so where is the best location?) or have a left side and a right

side penetration?
