i have a 32 gtr,
now on wendsday i took it to eastern creek and posted a top time of 11.7 at 115mph, with only a exhaust and 13psi boost, stock turbos, stock ecu
i was wrapt....
before this i could always noitce somthing like a choking feeling while the engine was reving out, and you could notice the torque loss, not massivly, but abit......
this was more only during the day time, during night it would run mad.... i put that down to intake temps
now, since i ran that time, the next day i went and put some cam gears on and set them to 2 deg advance on intake and 5 deg retard exhaust, ran the car, perfect, absolute animal compared to the 11.7 pass.... i couldn't believe it, this test was also at night, drove home, woke up im morning, and took for another drive, same as before, feeling lazy and choked up during the day, night came, abit better....
now tonight, i have noticed a big amount of power loss, and a shit load more laziness, the exhaust note has changed, sounds choked up, the engine builds boost good as i watch the gauge but its like the motor doesn't like the positive pressure its being given.... and lost throttle response...
i always put good fuel in aswell
also under load like at 2500rpm in 5th, ill put the throttle flat, and it will build boost probably up until 3000rpm and then the bov's start making their noises with my foot still to the floor...
now i think that this may be something to do with the computer, but im still unsure but wtf is the story with the bov's going off while still under load????
any1 with similar issues?? or theory's
any and all help is appreciated
cheers
