its not all about initial spool, its between gear RESPOOL. the 1.8t, especially under 2.0L displacement with a stock head doesnt flow alot in or out, especially if revving below 8,000rpm.
im not sponsored either. i pay my way and work on my own car. a .63 AR is all you need unless you are building a 2.0/20v with big cams and going after 600+ numbers
and if you want a .82 3076R, you should have just done a .63 35R. spool will be close on those. my 30R makes 24psi at 4300rpm, a 3076R will do the same at 4500, so with an 82 youre looking close to 5,000rpm for 24-25psi, which is 35R territory on a 1.8t
Well we will see I guess. Once the car is running the next seasons investment would be a big port head, cams and manifold. So I can take it past 8K. Then at that point, O2M maybe.
