106907, RE: Turbo "cold air intake" Posted by SilvrEclips, Dec-31-69 06:00 PM
So I finally got around to doing some logs with the CAI on the turbo and I took it off and ran no filter. I didn't feel like trying to fit the filter back on the car just for 1 pull. Anyways I got some pretty good results I think. I tried to keep the coolant temps about the same and sprayed off the intercooler before each run to eliminate a heat soaked intercooler. Im running a cheap ebay core and it sucks as you can see. This was on a td05 20g at 20-21psi.
Results: The turbo spool a consistently 100-150rpms sooner. Also peaked another .5-1psi of boost and held about .5psi more boost with the CAI on. This resulted in the car accelerating quicker, however the intake temps did not really change much. It seems like the temps were not increasing quite as fast but it was not that much different.
Here is a screen shot of both logs put together. The brighter lines are with the CAI on.
