    Engine knock with no boost

    found a crack in the downpipe right after it exits the turbo (3" downpipe) but did not see anything else on the headers or the crosspipe. Tried all of the tapping around and nothing registering on the knock meter. Pulled the MAF and it looks good. Wires hooked up correctly. Pulled plugs...

    Engine knock with no boost

    I figure the putt, putt is an exhaust leak because I had a similar issue in a 5.0 stang I used to have. Actually lost a small chunk from the passenger side header gasket on cylinder 2. Made a similar putt, putt sound. I will tap away when I get home later. Could the exhaust leak have...

    Engine knock with no boost

    Hello all, I have an 86GN that has began to knock. Now here is the weird part, I am not under any boost when it does it. Just subtle changes in RPM. Running down the highway at about 2K-2100RPM, asI gently press the accel pedal and the RPMs go up about 200-400, the knock gauge will start...

    Just curious about the backspacing

    Thanks for the info folks. I have found a set of rims I like. for the front I am going with 17x8 and 4.5'bs and a 245/40 tire. On the rear a 17x9 with 5"bs and a 275/40. Front should be golden. Hoping the rears are good without spacers or rolling. Thoughts??

    Just curious about the backspacing

    What is the max back spacing you can run on a stock brake/suspension setup without rubbing? Trying to find a set of 17' rims (either 8" or 9" width for the front and 9" or 10" for the rear). Are there variations from car to car (due to manufacturing tolerences)? Some say "10" wheels rubbed on...

    Did I mess up the ball joints

    Cool. I figured as much but never forgot to grease new ones before and didn't know how critical it was. Guess the sometimers is kicking in.

    Did I mess up the ball joints

    Hey everyone, I have a question, I just replaced some of the front suspension including the lower ball joints. Well got everything back together (finally) and torqued down. Drove to the grocery store (about 3 miles away) and when I was coming back, I realized I forgot to grease the new ball...

    Transmission leak

    Hey guys, sondering if you can advise me. I have a leak from my transmission on the passenger side where the circular cap looking thing is (pardon the lack of tranny vocab). What does it take to fix this leak? The tranny seems to perform just fine and I just changed the fluid (thinking it...

    Fan will not turn on

    One more thing. I was also considering running a hot wire on a switch for the fan in case I have problems again. I was going to run a 10g wire with a 30amp inline fuse to a 30amp switch in the car and then to the fan power wire. would that be ok? TIA for any help.

    Fan will not turn on

    having the same problem. Fan works if hot wired. Upon checking the red wires, I have power to the delay relay (red), but not to the high speed (red). I also have the 12V key on power (ECM/SOL fuse I believe) in the small black/pink wire. Checked the fuses and they are all ok. So if I am...

    For the alcohol gurus...

    Tahnks bison, I just found a post from 05 that explained what you are talking about. I have been using methanol since I purchased the car in June, but have access to all of the 3 types I have mentioned (price difference very close). The safety edge of methanol (vs detonation) that has been...

    For the alcohol gurus...

    GNBRETT Thanks for the quick reply. I did a search and read several posts. However, I did not see any physical data (I ran ethanol and had X et then drained and ran methanol and had X+ et; or changes in dyno numbers, etc). Most say "I run this type because it is better", or "that is what...

    For the alcohol gurus...

    Here is a question I have been pondering after seeing a post on the octane ratings of the different alcohols. With price not being a factor, is one of the common alcohols better than the other (ethanol vs methanol vs isopropanol) for injection or does it make a differnce? Could they all be...
