I have no degrees ... All OJT and some of that was crisis Fast Trak ... so this is worth just exactly what it cost, nothing ... if it helps, great ... I do keep meticulous records and know how to research ... I used a TOM's style scoop (made by Ken Schultz of KD Garage) and ducted it to the air filter housing ... (see pictures toward the bottom of the "Cars" page on my Web Site - Ken's MR2 Parts ... I closed off the bottom of the scoop, allowing for water drainage and installed a plastic nipple for the 3 inch hose, which fit the air intake of the filter perfectly ... the car is a 1986 NA auto daily driver ... fuel economy went from 33 mpg at 70 mph (consistently over 240 miles) to 36 mpg under the identical conditions ... I extrapolate that the fuel economy increase is due to thermal efficiency increase and therefore it can be assumed there is a power increase due to the same improvement ... one thing I am absolutely sure of, was it sounded great at higher rpm under load ...MosquitoXR13 said:So what about a Tom's style C-pillar scoop
This is a bit off topic here. But, thought I would add this bit of information. I modded the driver's side adding a sidevent. I made a fiberglass "scoop" (for lack of better terms) similar to Deno's. Sound increased tremendously. Went from "sounded great" to ear piercing when the valves open on the second set of lobes.The Money Pit said:... one thing I am absolutely sure of, was it sounded great at higher rpm under load ...
It's very possible that thats got more to do with a low pressure area above the lid, and a slight positive pressure area in the bay.filonin_2 said:I don't know if your model of air flowing through the engine bay is that accurate. At 100mph, my engine lid axctually lifts up to a 45 degree angle from all of the air going through there, must be more 2-3mph.
