Finally some good results (1.6L IM)
Finally got brad on the dyno to see what his 1.6L BEGi IM did.
It lost a little on the low-end during spool, but everything above 5.5K was an improvement. You can see the boost plots for each pull so you can see even with slightly less boost it's making a bunch more top-end.
Its running around 20-24* spark angle at 17psi which slowly drops to 16psi at redline, no matter what we couldn't cure this, he needs a new wastegate actuator.
His final numbers were 261rwhp and 221rwtq @ 16.1psi, not bad for a 1.6L with just a built block.
Setup = 2871, log manifold, 3" turbo back exhaust, BEGi IM, 70mm TB, .020" overbore, 8.8:1 CR pistons.

Mine has a larger plenum, slightly shorter runners (without the step change) and stock TB. I was hoping to run today as well and redo it, but I didn't receive a part I was waiting for.
This is the one on Brad's car:
It's 100% fabricated, unlike mine.

I'm using a begi 15 psi actuator, with my hallman it holds at 16 psi all the way to red line. Did the same when I tried 19.
