Hi all. Got some questions about the legacy chargecooler or an aftermarket upgraded chargecooler.
My car is:
'02 USDM Subaru WRX, 5MT, HKS panel filter, Velocity stack air box mod, Helix up-pipe, 3" turbo back exhaust & TMIC, STi hood scoop, Zerosports hood splitter, Profec B @ 16psi, 17" UK spec WRX wheels, EBC greenstuff, Prodrive springs and Scanmaster 3 OBDII tool. It dyno'd at 284.2bhp/265lbft with crap fuel. I plan on adding a big TD05 16g, injectors and fuel pump soon. I am going to ScoobyClinic Friday to have the car remapped with ECUtek.

Anyway, my friend, Ali, has a 1995 JDM import WRX wagon and we are trying to convert it to the Legacy chargecooler. We have a '02 WRX intercooler installed on it now and it made a big difference but we want more power! Now I am thinking of adding one to my '02 as well and ditching the Helix TMIC. Does anyone know whats the max CFM the Legacy chargecooler can flow? Is there an upgraded version of the Legacy chargecooler? Anyone successfully added the chargecooler to the late model WRX? What were the results?

Thanks in advance,
Steven
