Plenum dyno data

Plenum dyno data
So I installed my kinetix plenum and Z-tube today and although most of you would not consider a gtech pro a dyno here are the results anyway. Stock the car registered 216hp. With K&N drop in I gained 3 to 219hp. I picked up another 3 with the addition of Mobil 1 5W30 to 222hp. I put the tube and plenum on...drove it like I stole it around the block and onto the freeway for 2 onramps and back home. I purged the air from the cooling system (very important) and then went to a little industrial area by my house to get a little data. First, the plenum is not loud at all, neither is the Z-tube. With the radio on you would be hard pressed to hear the difference. After 4 0-100 runs here are the results. Run 1. 237 Run 2. 238 Run 3. 236 and Run 4. 238. It is about 65 here in San Diego with about 30% humidity. The pull above 4K is amazing and the tires (with the slushbox) actually break a little sideways at the 1-2 shift.
Lessons learned-
1st-Clamp the coolant lines at the back of the pleanum before removing them, this will minimize the air getting into the system.
2nd-Buy an inch pound torque wrench to tighten the plenum
3rd-Tighten the plenum bolts in a criss-cross pattern for uniform load.
4th-The ECU is a learning computer. Although resets may sometimes be necessary I don't think they matter that much unless you dramatically alter airflow (like a full exhaust with headers).
Anyways, thanks for reading and just for reference I have used the gtech for years in conjunction with dynos and have found them to be within 3-5 HP of a dyno every time. I have an HKS muffler and JWT pop charger on the way and will give more data when they are installed.

On the discussion of oil, I was at Murray's Auto Parts and they had an oil additive that was on display. Apparently, this additive has adhesive properties where it “sticks” to the moving parts of the engine. Would this be a product that would benefit our cars? Does it have any performance properties? Or, is this simply marketecture?

Not good for worn out beaters.... @ ALL.
