Roy Posted November 4, 2009 Share Posted November 4, 2009 Fark Dane! Mate, really feel for you! You are bound to turn the corner soon with that car! Hope its only a minor gasket issue etc Link to comment https://www.sau.com.au/forums/topic/291767-hsvoc-sandown-31st-october/page/3/#findComment-4917132 Share on other sites More sharing options...
phunky_monkey Posted November 4, 2009 Author Share Posted November 4, 2009 Well the engine builders don't think it's the sleeves as they don't protrude, and a new head gasket went in 2 days ago. Head was also just faced up when I removed it to fix a minor oil leak. It's very odd... and super frustrating. This is the third headgasket to go into it now (original, second as a precaution after one of the valves was found to be 3mm longer than the rest and head removed, then this one a few days ago), head has been off twice, and entire engine out twice. A buggered oil pump: fixed... then a longer valve: fixed... minor oil leak from head: fixed... then what we thought was a leaking headgasket: fixed... and now milky oil Just had it tuned at 285rwkw's @ 20psi and didn't even get to use it!

Downforce Posted November 4, 2009 Share Posted November 4, 2009 Nice power figure! Sounds like a weapon.. what's it weigh now?? If it's around 1200kg it would be super fast! Do you have a dyno graph to share... I'm interested in SR20 power curves..

phunky_monkey Posted November 4, 2009 Author Share Posted November 4, 2009 Nice power figure! Sounds like a weapon.. what's it weigh now?? If it's around 1200kg it would be super fast! Do you have a dyno graph to share... I'm interested in SR20 power curves.. I wouldn't know Matt, I haven't driven it! I'd say it weighs in around the 1100-1150kg mark with everything taken out, but the cage added in. But I'll get it weighed soon enough once it's working. It felt pretty quick on the 250 or so rwkw's I ran ever so briefly at Sandown so 285 sounds promising. Graph attached mate. It lost some power through the mid range with the cam timing change from it's initial Winton-last-minute tune, but gained a heap up top. Boost response is identical to what it was with 240rwkw's, and on the same boost level it makes a 45rwkw gain. It's also running 11.4 AFR's as we had a boost leak at the injectors so were running on the safe side in case they decided to seal up while I was running, so there should be a bit more in it at the same boost level. Troy: Stay with the 240 mate. This was not worth the expense and hassles, despite the nice figure. I'm sure it will be great when it's all sorted but I could have been racing this whole time and that I won't get back. But as Russ said, if I were to do it again I'd buy a crate engine. 285 Pre-Winton last minute tune 2lt tune, same turbo setup Link to comment https://www.sau.com.au/forums/topic/291767-hsvoc-sandown-31st-october/page/3/#findComment-4917682 Share on other sites More sharing options...
Roy Posted November 4, 2009 Share Posted November 4, 2009 Can you get Sam to overlay it with my RB20 and TD06 setup from when i ran it on his dyno with my old tune? Be interesting to see how they compare? Link to comment https://www.sau.com.au/forums/topic/291767-hsvoc-sandown-31st-october/page/3/#findComment-4917713 Share on other sites More sharing options...
phunky_monkey Posted November 4, 2009 Author Share Posted November 4, 2009 Shall do mate. I'm heading there tomorrow so I'll ask him then. I'd say yours makes more power across a broader range at the moment. I think once the boost leak is sorted it will improve a lot though but we'll see.
