202.3rwkw

hi guys, does mobil 8000 contain ethenol? if so i would be banking on that if you're running aftermarket management. glenn

hey guys, i have an r33 gtst fitted with a plazmaman front mounted plenum. to speak of the gains, i had the car dyno'ed at 202.3rwkw with just a front mount, exhaust and pfc. we added the plenum and immediately picked up 20rwkws. The big positive was that we were able to add anywhere up to six degrees of i/t across the maps. Throttle response is noticably improved. On the negative side, idle is now a little lumpy due to the removal of everything except iac. all in all thou i now have 220rwkw for just over 1500 spent. was it worth it? hell yeah gc

apart from your aac valve on the manifold plenum there is a valve UNDERNEATH the inlet plenum/manifold that adds air according to coolant temp based on maps in your ecu... this valve can destroy itself and cause all sorts of problem!!! this is diagnoed by crimping hose and listening for idle rpm change ie: should drop. if this is the case.. you best plan of action is to make sure that this valve stays shut!!! hopes this helps!!!!
