ARC IC dimension compared to stock
I just got my ARC IC from Jesse in Japan. I don't like front mount and all the necessary piping, so I went with a larger stock. Couldn't beat his prices so I got an ARC stock mount IC.
Here's the relevent data compared to stock
looking from front of car
ARC IC- width (shock tower to shock tower) - 9.5 inches
length - front of car to back)- 10.25 inches
thickness - core - 2.75 inches
surface area - WxL = 97.375
total volume - 267.78
Stock - width - 11.375
length - 6.25
core - hard to measure 2.75 or 3 inches
surface area - 71.1125
total volume - 213.3375 with a 3 inch core
195.56 with a 2.75 inch core
Should be a nice improvement over stock even with it being stock mount. It also has a better design in that the outlet drop straight down instead of the stock having to S back toward the throttle. Less pressure drop through the system, means the turbo won't have to work a hard, means cooler charge air leaving the turbo, further cooled by the better IC. I'd do a dyno run, but the friend I bought the car from didn't have a boost gauge when he ran so I don't know what he had it set at then. With no idea the boost pressure, he had these mods : (89 TII) cone K&N intake, underdrive pulley, DP, MP, catback, REDOM jap spec tuned ecu....made 231 rwhp and 256 ft/lbs (spiked) highest flat part of the torque curve was 227 roughly.

I'll get some silicon hose and hope to have it installed soon. Then its dyno time.
