MS-75 Regular Location: Adelaide Registered: June 2002	Re: Crown Progress...(1st dyno session update) Tue, 28 June 2005 23:17 The Crown was strapped down at Blackwood dyno yesterday for it's first session with the new plenum, wastegates and turbo-and all went swimmingly. The two gates gave boost so stable that the boost line was ruler flat (nil spikes) with the adjustability in the order of 0.1-0.2 psi, and the cooling circuit improved the engine temp stability so much that during the session the coolant temp didn't go over 94degrees (despite being flogged with up to 20 power runs) The big turbo has also meant it hits the dyno a little softer down low so wheelspin wasn't a problem. The 12 injectors performed flawlessly, with injection time at idle now only 0.8msecs. The tank was filled with 70% BP premium and 30%Toluene. We didn't get to putting the martinin race fuel in as was getting a bit late, and after 2 hours in the dyno cell of power runs through a 4 inch side-pipe and screamer pipes on the two wastegates I'd had enough (CO poisoning, deaf, hot etc-yes I am soft) Anyway, things were looking promising when it settled in for a 247kw run on about 8psi, and it went up from there. We only ended up at the same boost I ran last time with the old set-up (last time 14psi gave 281rwkw), but it gave a grand total of- 321rwkw@14psi, just on 5000rpm.....Tractive effort was over 10,500N The two final runs of 321 and 320 were the last two for the session meaning it was well and truly hot by then, so the figure is a solid repeatable number, not a cold start power run to inflate the number. So, Big turbo and new plenum, along with 2 degrees extra timing netted a 40rwkw increase on the same boost level-awesome. Yet to come will be more timing (still very conservative as with the sidepipe and screamers it's impossible to hear detonation) when I have a full twin 3 inch exhaust on and a microphone on the block so I can hear any hint of a rattle. Also keep in mund it's still running stock cams and ports (slightly cleaned up though). I'll put up the various graphs tonight when I get home. Considering it ran 125mph with 281rwkw last time out, the 40 rwkw increase should blow that out of the water...... [Report message to a moderator]
