Last week I was able to get the drag car on the Monkeywrench dyno for the first time with the new 2.0l setup. This is identical to what I was running last year externally, just the 2.0 crank, grp alum rods, and 9.5:1 wiseco pistons. I was there to gather data, but was able to turn up the wick a little bit.
This was 44psi on an 82mm inducer Borg Warner turbo, burning ethanol and through the auto trans:
These were just 4-sec pulls, so it appears to spool lazier than it really does by the plot. It will make 27psi at 6200rpm and probably more as we saw that in the first pulls of the day that we were cutting off at 6200. It also probably has another 20psi to go. I'm very happy with the numbers.
I have a ton if data to finish processing still. Included in what I will share is some intake port dynamic pressure data, taken at 60kHz. I only have that up to 24psi boost, but it still appear a very interesting. I also have cylinder pressure on #4, and I will share some of that data later as well. That requires way more data processing than the port data.
