I have been running a 6psi Wynjammer supercharger on my stock engine for 4 years. I have made tweaks as needed to run it within reason. I have an engine file attached as to how it is setup using a stock camshaft. (NOTE: Using Accel Supercoil, TRG55 plugs, JBA shorty headers, stage 2 street/strip 4L60E transmission with 2600rpm stall TC, have posi 3.73 rearend diff, stock tire height.)
When I put a new stock 4.3L V6 engine in my truck, I am going to remove the stock cam and add a supercharger cam to compliment the low boost range I am running in. Could someone help me with the necessary changes I need to make to my current engine profile to compliment the supercharge camshaft profile? My concerns are proper idle and modest drive-ability once the engine is in. I will tweak as I drive it daily. Please see below:
Stock Cam Profile
191/195 @ .050”, 260/263 adv, .414”/.429” lift, 111 lobe sep, 106 int center line
Supercharger Cam Profile
218/224 @ .050”, 270/277 adv, .492”/.501” lift, 114 lobe sep, 114 int center line/114 exh
NOTE: I am running only a stock MAP sensor, so the method used to compensate for the boost is by bringing in the Power Enrichment at 1500rpms. This has worked "OK" for 4 years. I will eventually convert to an aftermarket system. But, in the meantime, I will need to get this engine up and running to drive. I am aware of many other aspects, however, feel free to bring them up as "Future" concerns once I get the engine up and running.
