here is the deal. I am building a RWD Mk4 jetta drag car. Built 1.8T, crazy AEB head, ford 8.8 spooled 31 splines, 4.10+ with 26" tires, ladder bars and coilovers, and a powerglide in the middle.
I am trying to figure out the converter. Assuming you want the lock up to occur just prior to full tq I am having trouble coming up with a stall speed, since the lil 4 banger makes tw right up to redline. my last setup with a 3076R .83 spooled up 26psi at 4100 and tq really took off around 5K and went right up until redline nice and steady. the turbo I wanted to run this time was a PT6262 .83 est. 26psi or so around 4500. the cams in the head are schrick jobbies that came with the solidlifter conversion, so I cant seem to find too much data on where they make power. I had the grind numbers somewhere when I bought the head, but I dont have them off the top of my head to compare them to a CAT or something more prevalent.
what do you think? Anyone with automatic transmission experience something like this? lol
