Thread: Knock

if you have the torque app its the best one. only works on a droid system tho.

Good god. I think Scotty is right, stop beating on the car ASAP. If that 6.5 degrees of timing is accurate….

^^^exactly, it won't last long with that timing. Your gonna have a chipped piston mod soon. I'm freaking out over 3-4*.

i was down to 5* of timing when i had 8* of kr, but i was also stock.

you should really take that pulley off till you get headers or a 3 inch down pipe and a plog. hint headers are cheaper then the dp/plog combo.

getting a tune cant hurt either.

the dp should help. scrap the res, buy a glass pack have the shop install that in place of the res. they are like 25 bucks at the parts store.

speed daddy was selling a plog, but ive not seen it in a long while now, it was a 120 iirc.

thats not a bad price really. glass packs come is all lengths, i got a 32 inch glass pack in my car.

regals have a longer res then a gp. i measured up my old one, bought one that was close. it was a 30 inches long. so i got a 32 g/p. i cut the inlet tube off welded a flange on it to make it 2 inches shorter over all.

its a muffler shop item. cost me 10 bucks. gasket was like 8.

i got the gasket at the parts store, then matched it to the flanges on the shop wall, cause they all looked dumber then dirt and i didnt want to get screwed.

every last pipe connection now has a band clamp on it. once i put the 3.4 pulley on i was blowing sections a part one by one lol

im up to 6 band clamps now, headers to muffler.

i wouldnt be worried about the boost right now....it would be throwing your 3.8 pulley back on the car or driving like a grandma until you get it tuned properly.
