I put SLP's cold-air induction on my '97 Formula a couple years ago.
Last November a young lady darted-out in front of me to get T-boned
and buy me a new SLP "RAM-AIR" hood. Based on the 20HP gain SLP
quoted for the cold-air setup vs the 15hp gain they quoted for the
ram-air package, I just left the cold-air in place and have enjoyed
the looks of the non-functioning ram-air hood.
With the Augusta, GA heat in the high 90's, my quarter mile times have
diminished by 4/10ths. I started thinking about the intake air
temperature and what I could do to cool it down. That's when I put my
hand on the steel "cold-air" pipes after a short drive. They were
I decided drag-radials were a better $300 investment than the hardware
to make the ram-air hood functional (I get little traction off the
line); so I dreamed-up a $10 modification, I wondered what you guys
think of it...
Basically I just went to home-depot and bought some silver-coated
insulation and matching silver (reflective) tape. I cut and taped the
insulation around the cold-air induction pipe from where it enters the
inside of the hood up to the MAF. The idea being that the "cold-air"
passing through the steel (highly conductive) pipe is probably gaining
a few degrees during the trip.
I may not be able to test this mod at the track before I get my new
drag-radials on the car, so I might not know how beneficial it
actually is. My question is, do you think it is a good enough idea to
test independently? Do you think it will have any impact on my
quarter mile time?
