white-gt Posted July 30, 2013 Posted July 30, 2013 Hi fellas, i recently refitted a hybrid on with the same hks actuator and mbc etc which is all good. i finally got it sitting at 1 bar via the mbc but! it was running about .9 bar and it just didnt feel that great, i then adjusted it very slightly to 1 bar and the car spooled so much quicker and took off, seriously! i thought great! awsome! but again it seems to have slowed down and doesnt take off as well as it did any more, its hard to explain. it still pulls decent etc but not how it should i dont think. i do have a slight crack in the mani but even still. no boost leaks as i checked them.is it possible its an actuator issue or mbc? when it was rolling roaded it performed a load better when the mbc was fitted as the actaator took longer to spool up etc, not sure if that helps. Currently running a dastek unit with all supporting mods etc. whats your thoughts? Quote
pick1 Posted July 30, 2013 Posted July 30, 2013 Is the actuator sticking dude check that the arm etc moves freely as that can hd your boost bk and not let it go full chat Quote
mikey4410 Posted July 30, 2013 Posted July 30, 2013 tbh a small/little crack in mani can make a big difference to it boosting. whats your air /fuel like at wot ? Quote
white-gt Posted July 30, 2013 Author Posted July 30, 2013 Thanks for the replies. I've no idea what the AFR is.. I need to get a gauge tbh.When it was on the rollers on a standard ct9 arb 1 bar it was about 12 AFR on wotI'll check the arm but I'm sure it was fine when I last looked.. Quote
mikey4410 Posted July 30, 2013 Posted July 30, 2013 U wana hope it werent as high as that on wot as thats pushing it with a ct9 @ a bar. Quote
jezza Posted July 30, 2013 Posted July 30, 2013 I mentioned last time, I dropped about 40 brake with a badly cracked mani. You might find the power drops as the mani heats up and crack opens. Quote
white-gt Posted July 30, 2013 Author Posted July 30, 2013 its not badly cracked though, it will be getting replaced at some point soon though. i will try take a pic of the power graph for you guys to see. Quote
white-gt Posted July 30, 2013 Author Posted July 30, 2013 (edited) this was on a standard ct9. the red graph was using the actuator alone, and then blue was with the mbc. Edited July 30, 2013 by white-gt Quote
jellybaby Posted August 3, 2013 Posted August 3, 2013 Tbh the crack how ever small will effect things as the air is escaping and pressure will drop Quote
