The insulation idea, is interesting. Would I put this inside the enclosure? Maybe roll a piece and insert in around cone filter?

How does this stay in?
You put the insulation on the outside of the airbox, and once you get to the front of the airbox you continue it onto the front ledge under the hood to seal the top. Then you continue it on the sides and fasten it to the front so no underhood heat can get in. You don't put any of it inside the airbox, that doesn't do anything but disrupt the airflow. It stays in with tape. I will try to find the website with the write-up of that on it, it will explain it very well.

Here is the site. I think it will give you a pretty clear idea of what I am talking about.

Awesome! So I basically just "wrap" the CAI enclosure with insulation and secure it with insulation tape.

The instructions also see to use the insulation to fill the gaps between enclosure and radiator/fendor.

However, will this allow me to get enough air - especially on the SSEi?

I was under the impression that the bonnevilles didn't have as much airflow through fender wall or headlight.

You need to put insulation everywhere where underhood air can get into the airbox. Bonnevilles don't have as much airflow through the fenderwell or headlight, but the little flow they have is the only flow they have, because you don't want to use the hot air from the radiator. Just seal off the box the best you can from the engine bay trying to disrupt airflow as little as possible.

Default yet another run

I did another run tonight. The outside temps and intake temps where slightly cooler. The outside temps ranged from from 70F to 72F. The intake temps ranged from 79F to 120F.

I left the traction control on the whole time, and did not have the airconditioner on.

The KR at WOT ranged from 0 and less then 1 to a spike of 5 or so (at let off/upshift). However, there was never any knock sensed. The knocker sensor count stayed at 0 the entire time.

The KR would often decrease or at least fluctuate as RPM and bost increased.

Does that mean all this knock retard was PCM intervention for safety or to protect the tranmission ans engine?

Maybe my PCM is just being catuous based on what learned from before headers and rockers were put in?


Would the new DHP for bonnevilles fix this?
