speed density
i've been told some of the lightings ran a speed density system. i have an 89f150 4x4 with a 351w. i want to supercharge it. however from what i understand you have to do some things to "trick" the speed densityl system. anyone with any information on how to supercharge a 351W with a speed density system i would greatly appreciate it. thanks

You can use a boost/timing retard, FMU and boost activated inline fuel pump. These components will work with almost all of the factory kits available for your truck. The stock injectors will work fine as long as you keep the fuel pressure up. Larger injectors and some type of aftermarket tuning would be a better route to go with boost and speed density though.

As far as I know The only way you can modify a speed density system is to A) switch it to mass air or B) Buy a PMS unit that will pigtail in between your stock wire harness and your computer....and with this you can program your own settings. Option "B" from what I was told is better than converting to mass air.

SCT and Tweecer can also be used to tune it. If you plan to go that route, I'd recommend you invest in a wideband O2 (to monitor the air/fuel ratios) and a cab mounted fuel pressure and boost/vacuum gauge.

Yes, it is a little challenging for a beginner. I think many speed density equiped F-150's can use the same strategy as the GEN 1 Lightnings. You'd have to contact them to be sure though.
If you decide to do your own tuning, be patient and ask questions, and make sure you have all of the tools need to help dial in your combo; at the minimum I would suggest using a wideband and fuel pressure gauge.
