I like the Spectre intake for the Cadillac STS-V.\u00a0 However, when we put the intake on we discarded the factory engine covers along the front and side. The Spectre intake includes a barrier to direct air away from the intake filter, but it is not closed at the top.<\/p>\n

Cadillac STS-V Spectre Intake filter and air dam<\/p><\/div>\n

I was considering building an insulated cover or box, but it is desirable to me to re-use the factory trim pieces.\u00a0 Also, there are some functional air blocks built into the trim that I want to recover use of — example the foam air dam below the center front piece, and at the rear of the driver side piece.<\/p>\n

\"\"<\/a>

Foam on the under side of front middle trim acts to keep air in the radiator flow<\/p><\/div>\n

The factory piece that would fit over the driver side won’t fit with the Spectre intake in place, so I trimmed the side piece, and the front center piece, to allow them to fit with the Spectre Intake.\u00a0 I need to get some rubber gasket material to close the gaps, and smooth the edges, but now all the pieces fit.<\/p>\n

Even though the V was hot I did a test and data run:<\/p>\n

\"\"<\/a>

Max calculated power for the test run 415 hp in 2nd gear at 6346 RPM for comparative purposes; max torque 377 lb ft at 3324 RPM.<\/p><\/div>\n

 <\/p>\n

Unfortunately I only have a heat-soaked mid-day comparison run for today.\u00a0 I attended Church this morning, then worked on trimming pieces, then did a test run.<\/p>\n\n\n\n\n\n\n\n\n<\/colgroup>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

There is a lot to read and try to analyze here, but let’s piece it together.<\/p>\n

First, today is cooler than back in August, 75F instead of 90F.\u00a0 However, my STS-V is heat-soaked today and wasn’t back in August.<\/p>\n

IAT1 is 16F above Ambient now and was 23F back in August.\u00a0\u00a0 That is what the trim is supposed to help with, so good.\u00a0 In August the 0-60 run itself cooled the IAT1, while it did not today.<\/p>\n

IAT2 was only 2F above IAT1 in August (morning run, not heat soaked); today it was 33F above (heat-soaked).\u00a0 In August the IAT2 gained 17F during the 0-60 run; today 12F.<\/p>\n

MAT in August gained 49F on the run; today 41F.<\/p>\n

I am cautiously considering replacement of the trim beneficial — did result in lower delta temps.\u00a0\u00a0 I would like to have a non-heat-soaked current run to compare for apples to apples however.\u00a0 There are still some gaps in the trim fit that will benefit from some gasket material along the edges.<\/p>\n
