I posted this on passatworld but I thought I'd give it a go here too:
(B5 Passat 1.8T)
While I was talking with John from Alamo industries about porting my turbine housing he made an interesting point. It's possible that the stock intercooler may be acting as a bottleneck. Apparently if this is the case then it's efficiency is piss poor at best.
At some point I'd like to measure the pressure difference between pre-intercooler and post intercooler pressures. If I'm finding a significant drop I'm faced with one of two options. 1) I spend $500 on a FMIC That's going to tear up my front bumper and still going to drop my PSI or 2) eliminate the intercooler all together and run on straight water/meth cooling.
Now before you all hit the "you're going to blow up your engine" key hear me out. For $220 (boost solenoid included) I can get a safe injection kit that monitors the actual flow through the W/M line. If for any reason the flow cuts out it will actually dump all boost pressure via the wastegate line. I figured what I'd also do is split my lines and put a second, small 60 ml/min nozzle around where my intercooler used to be (in addition to the existing nozzle still by the TB)
Anyway, has anyone heard of someone doing this? Also, does anyone know how much air the stock intercooler can handle before it starts backing up?
