hi, this is my first post in here. n my eng not that gd.i just bought a ae92 with stock sc ae92 map sensor,
n done some mod,
large pulley changed,changed top mount arc,n i found out there a lag on between 5500 rpm during daily driving n in dyno also show,after i use front mount the problem really solved n the power band push it to the back 5000 onward is very gd compare with top mount,but the 300 abit poor,
with top mount the power come early n power die when reach 5500,let make it like this way, when i push my car to the limit mean 7000 rpm n change gear my rpm will drop 2000 rpm mean 500rpm ngam ngam the the way tat the power die, so do u think the car still can move?
i try both way, take out the top mount n go for front mount,front mount might delay but the best is the engine power comes slowly in low rev n 5500 rpm the car pull even faster to 7000rpm,when switching gear the time during high rev 7000 rpm the rpm drop 2000 mean ngam ngam 5000 rpm mean the power band that join n it kick,wont like top mount change gear during high rpm sure die..
i tried putting back the top mount but after a week the front mount still the best..
my car is running in large pully,nology,arc top mount tested but front mount still the best,blitz open port n plug n play hks pfc f con,
next going for sc93mm pully,port n polish big port head with na 250 cam,our sc stock 240 if not mistaken, hopping that can get 1,3 bar,previous now is running 1.0 bar ...
the orange is running with stock sc12,
bue is my future twin charger but might not gonna happen.
