My 1987 WE4 is dialed in on e85. IDC is at 80% (60#) with an afr of 11.0, 22psi. I am going to swap out the 2 year old racetronix pump with a DW301 in the near future. No track time, just a street car for now but i'd have to guess low 12's with my combo. It's a blast on the street!
I thought I'd be happy at this level but you know how it goes. I'm considering bumping up to 80's and a bigger turbo (currently running a rebuilt stock turbo). I'd like to stick with the stock ecm. My question is the about the stock downpipe. I'm running a 2.5" pypes cat back and test pipe. Is the stock downpipe a restriction at this point?
