got out for the last race of the wa state sprints. Had a pretty ordinary day. But managed to pull it together for the last run and actually caught the car infront for a re-run.

First run and the car was overboosting pretty bad. Was hitting 1.8bar on a tune that is supposedly wastegate pressure up top. Brakes felt great for the first corner or 2, then turned to poo. The QFM AR1Ms just cpuldnt handle the heat.

So when i got back in, I ripped the TMIC off and re-routed the boost plumbing for a true wastegate pressure setup. Was under the pump time wise and only just got it back together for run 2.

Got out there and the car was gutless and farting all over the place. I knew staright away it was a boost leak. Pulled off after one slow lap and sure enough, i kinked the TB coupler on my rush to get it back together.

Fixed it for round 3. And got out there again. Car was driving great powerwise. Was sitting on a steady 1.5 bar going through the gears. Dont know how it only pulled 1.4bar on the dyno. Must be a boost creep thing when going hard through the gears? Anyways. 3rd run was better. Brakes were still crap, but i was getting used to it. These pads performed worse than the stock standard Wilwood 'street' pads when hot. But they perform better when cooler. So id rate the QFMs as a good street pad, but a sh1t race pad. Will call GSL and see what else they got. (they recomended the QFMs) But i forgot to dial in some DCCD. The car was very taily and i had a bit of half on half off lawn mower power slide action into the main straight haha.

4th run and things were going good. I remembered my DCCD, had a good handle on the crappy pads. And did a decent run. I actually caught the car infront and got a re-run. (didnt get a time for the 4th run.

The 5th run (re-run) was almost straight after my 4th. So the car/tyres were good to go. The pads werent, but i managed to drive around it. kinda. Had a hairy moment out the back and almost overshot the corner. But overall managed a decent time.

heres the morning results.
