Yeah facebook and its buried posts :wall: The link with some install pics can be found here .. ... 7954901935

Really neat install and got the results they were after with 21PSI of boost running E85 and stock 1.3mm plug gaps.

That's a really clean install. I like the way they have made the coil boxes and protected the coils from radiant exhaust heat.

I'm now running Autolite 606 plugs gapped at .055" (1.397 mm) With Bosch leads and MSD 3rd gen coils on our L67 seeing about 11psi in the LIM with no misfires as far as I can tell. This way it runs better than the 1.0mm gap that most recommend with 10psi on the L67....

The1 is also seeing good improvement running n/a with larger than standard plug gaps and better than stock coils. Clearly there is an advantage to better/stronger spark plug gaps/coils for economy as long as you don't induce a high load/boost misfire.

One day I might try this setup with LS coils on the L67, with the current setup I was getting a idle miss on the old plugs that were over .060" (I stopped measuring at this point).
