NA High Compression water/meth update

I'll be there next weekend

Here's the dyno run. I had an experienced SCT tuner work on it all day. 93 octane pings at stock timing with the A/F ratio in the graph. With the Boost Cooler I'm able to use stock timing (and probably beyond) with the same fuel grade. Maybe the compression is higher than that? It's an Aviator short block and definitely has a shallow dish. I'm not sure if it's exactly the same as the Cobra dish though. I'm also driving in FL heat.

I was able to run 25 degrees at WOT on my setup. I do have Cometic head gaskets though, they make a huge difference.

I take it you are running the stock head gaskets?

 

[mrshl13]

Yes I am. The latest generation of Ford gaskets at the time (last Fall).

Thanks, Damacman. I still see an arming (master) switch in your diagram. I'm going to try the switch I already bought and see if it helps. If I still have issues (the most likely of which is being able to adjust the vacuum switch properly since the Snow instructions indicate the adjustment of a boost switch and not the vacuum switch...don't know if they adjust the same or not).

I'm really not having any problems when driving it. It now breaks loose in 2nd gear when I hit the powerband and doesn't seem to be bogging any.

Pics of the finished product:
Pump-on LED placement
Stock-looking enginge bay, not belying the 300HP monster
The relay and conduit
The vacuum switch, mounted with zip ties per an addendum to the Snow instructions
The only thing giving it away is the red tubing and nozzle in the intake tube
