Got the exhaust all sorted and headed to the dyno on Monday.
Got a bit of base tuning done, then got it onto the dyno.

Well... First and foremost, then engine didn't explode! which is a bonus.
Did a few runs to check things out, and it was all looking good. By the looks of things though the boost has dropped quite a bit with the new capacity. it's only making about 8psi now where it was almost hitting 11 with the 1.3.
Unfortunately we we got to about 80kw, and the clutch started slipping. I had bought a decent exedy clutch, but it ended up being the wrong size, so had to get another at short notice, which turned out to be a pile of shit.
So we left the tune at that.. Lin (tuner) tidied it up a little and we pulled it off the dyno and I headed home.
On the bright side, it'll give the engine a nice wear in period, and give me some time to fit up a larger 1zz throttle body and get a new pulley made for the supercharger.
These M45's are the same S/C as the mini cooper S uses, and there's a lot of guys running up to 1bar through them, so I'm going to aim for something closer to that and hope the damn thing doesn't melt.
