MS-75 Regular Location: Adelaide Registered: June 2002	4.5 L Crown blows up at AIR Mon, 06 September 2004 02:16 ONLY KIDDING I thought you guys might like to hear about the crowns second visit to AIR-following the first visit with na 11.65 recorded. Yesterday I took the crown to the track again, with the only mods being- A little more boost (1.2 bar) and a little less timing (I was intending to creep the timing up each run while checking the plugs-but didn't bother in the end-I'll do that next time) All the rear end bushes replaced with urethane to combat the wobble it got up last time. Anyway, it was running really well, and I'm still getting a handle how hard I can drive it off the line. The rear end was solid a rock at speed so the stability problems were solved by the bushes. It was funny being next to guys in V8s with open extractors in the staging areas as the only way I could tell the car was running was to watch the needle on the boost guage or fuel pressure guage-even better though was then lining up and wiping them off the track....... Run 1 (Simex 225/75 light truck) 60ft 1.946 ET 11.553 MPH 125.26 A good start and confirmed the car was in good shape (whipped a 355 stroker VN-it sounded and looked killer) Run 2 (Simex 225/75 light truck) 60ft 1.857 ET 11.378 MPH 124.51 I figured that surely the simex tyres couldn't go much faster than this! (ran a crappy XB V8-he ran about 15) Run 3 (Simex 225/75 light truck) 60ft 1.858 ET 11.807 MPH 122.88 (ran an WRX STI but think he busted something at about half track) I also tried more gas after the 60ft mark and it went up in smoke pretty badly-as shown by the 11.88. Seeing as I figured I'd reached the limit of the simex light turck tyres, it was time to put my money where my mouth was and put the set of hand-me down McReary DOT treaded street/race tyres on it. They hadn't been on a car in 2 years so I gave them a good roasting in the burnout to get them nice and sticky. I then gave it a little stall on the line-but only about 1500 rpm to make sure I didn't spin out of the hole. Once rolling and about past the 60ft mark I gave it a lot more than I had with the radials and the tyres hung on no worries at all. By half track I knew the run was a LOT faster. Run 4 (McRearey G-60 Road Star treaded DOT X-ply) 60ft 1.796 ET 11.049 MPH 125.12 I was in the last pairing for the day so there wasn't a chance to go again. Next visit I'll get some launching practice in and find out how hard I can go on these tyres. SO CLOSE TO A TEN IT'S NOT FUNNY!!! It's not a bother though, as to get that close on the first run with sticky tyres ever and only the packages 6th run down the strip tells me a ten isn't far away. I'll post some pics up tomorrow.
