Yes speed density and 5-6psi
Reply #1 –
I was but had some low vacuum problems that should have been worked out completely before installation. If the map doesn't see correct vacuum or sees boost, it isn't going to be happy. An orifice and/or a one way check valve should be installed to the map sensor. Superchargerhelp.com has diagrams and posts of numerous people running boost with speed density. An adustable fmu is a must as well. Unfortunately, my supercharger had some internal issues so it's off the car right now. I have a shim kit for it and modified impeller, no excuses just plain lazy. Hopefully better results will follow. Lol the impeller became my avatar. During the "Slopoke" run it made 16.4 at 86mph pass, but it may have only been putting out 3psi of boost and there was a good amount of in the trunk. Also you should keep the stock cam or make certain an off the shelf one will work with speed density or better yet go custom. Hope this helps.
