CAI, experiement

[Redtruck-VA]

This morning I left out of the house when it was still cool. Man, Red was jumping, she really likes the cool air. I have a K&N -77 CAI with a cone air filter located over next to the fender. I also have the IAT mod telling the PCM the inlet air is 10 degrees cooler than it actually is. Later in the day I dialed up ambient temp and IAT temps to compare them. Ambient temp was 81 and inlet was 79, that is hardly 10 degrees. Anyway this got me thinking maybe I should try to actually make the inlet temperature lower. Stop by Lowe's and picked up a roll of silver covered insulation and some HVAC tape. Wraped the K&N chrome tube and double the insulation thickness on the bottom. Tested it and got Ambient temp of 80 and inlet temp of 69 degrees. Engine feels great, Did two launches. My usual routine is, turn off the OD and put the lever in 2nd. Touch the brake and roll down on it in a smooth motion letting off the brake just off idle. She spun hard and shifted, which isn't normal. Launched a second time and held the lever in 1st and manually shifted and she move out nicely. Side note, upgraded my valve spring tool with a grade 8 bolt, went by the dealership and of course they didn't have any keepers in stock.
