detonation? maybe....
ok so my girlfriend has a 87 turbo 2 with a s5 turbo and ported wastgate and a 255lph pump.
heres my problem, i work on FD's so im not as up to par on FC's but when i get into boost theres a random click or clank in the motor, it dosent studder or anything it might be detonation i think, so i checked timming and its dead on, i replaced the plugs, checked the TPS still nothing outof adjusment. so im here scratchin my head, im going to change the fuel filter just for ***** and giggles, she's running 10lbs though it so i just can understand why its doing this any ideas would be great.
thanks
Robert

Hopefully your running a standalone or RTEK. 10lbs is to much for the stock injectors. If you have a boost controller try turning it down and see what that does. Hopefully the motor isn't blown.

I'm pretty sure my motor isnt blown, i drive it everyday and it runs like a champ. The clank that hes talking about doesnt happen all of the time and sometimes it's not just one, it'll be two clanks sometimes. And also, sometimes louder then others. I honestly dont think it sounds like detination but, what do i know. The noise always comes from the drivers side if that helps any. To me it sounds more like a misfire, then detonation.
