Well guy's I took the plung today and installed my new C & L Billet Aluminum Plenum and a Phenolic Spacer kit. There is definitely a Huge difference in the size of this plenum, verses the stock one. I took the Lightning out for a spin after we installed it and I could not believe the responsiveness of just this simple 45 minute installation mod.
The Lightning felt strong today, all the way through the powerband, verses what it felt like before. Overall drivability is definitley better, especially when you let off the accelerator. No more sudden decrease in the throttle release, when taking your foot off the accelerator, but now a steady smooth transition , coming down off acceleration.
No, it was not just that regular seat of the pants feeling, as you know this Plenum is on there. I will take it into the Dyno in a couple of weeks, as soon as I get a few more things tweaked on this vehicle, to see what HP Number and TQ I picked up here. I am thinking with the Accufab Throttle Body, being on there from before installing this New Plenum & Spacer Kit, that I must have picked up at least another 15 horsepower. We will see.
