I just installed a DIY alky kit, using Steve Monroe's setup as a guide. For you Steve and all others reading this post, I just want to say thanks!! This stuff changed everything. I'm not even done tuning yet and I'm able to run 20lbs of boost on 91 octane pump gas with .54 degrees of knock. Showed absolutely no knock at 18 lbs. Before I was getting 5-9 degrees! Nothing else has been done other than adding the alky kit! I'm freakin' amazed!! And guys, this was in 95+ degree ambient temps!! I used the stock pressure switch that works the dash boost lights to regulate the turn on for the alky pump so I have to play with that to get the setting right. I think it's spraying too early. The car sometimes bogs a little bit if I accelerate slowly. Other than that I'm really pleased with it. Can anybody tell me how to use a Mighty-vac to set the pressure switch?? I tried using the pressure port but it doesn't build any pressure that I can tell. Thanks again!
