last nite i got my 2 sureflows 1600s. installation was ok. i didnt have superglue put i was able to secure the backplane on the hanging bracket with 3 cable ties.. its nice cause i can remove it by cutting them off. i have pics and i will post them later after work.
also sliding the bracket into the mj1200 was troublesome cause you have to clean and scrape off the coraline so that it will slide all the way in.
the performance was good, noticable improvement. the flow is wide. its a good buy, wish i had a bit more but i dont think if it did 2000 gph, it would not be any better.
now the first sure flow i installed, performed flawlessly, no noise, no chattering, could even tell a mod was on. real happy with this. the second one, YIKES, mj rattles, all kind of noise and chattering. you can see the MJ1200 moves in circular motion exactly like a really bad tire balance. its exactly that, its out of balance.
i checked it and say nothing out of place, since its a balance issue, some piece is off. i let it run for a few hours and every once in a while the balance comes in and out so i will get noisy chattering and then humming. the first one, nice quite not even a hum. it did this all night. i dont think an unbalance tire will eventully balance itself on the road, so do you think this sure flow will?
