Detonation?

AmBo · Aug 27, 2006

Sup guys, well the story of my supercharger is as you all know problem after problem. My dyno appt for Saturday was cancelled as the shop cloesd. Yay...so I haven't really been able to get on her too much as I'm not even sure the a/f is perfect. She seems to be running strong and I've had no issues with her.

So I go out to show my brother the blower and I start her up, pop the hood and give a light tug on the throttle body to open her up a tad. Maybe to 2,000 rpms. Then I hear a *POP!*. Sounded like a tiny gunshot. Detonation? So I let her idle for 30 seconds and she was fine. I got in the car and slowly raised the rpms to 3,000 and back down. Nothing. Was this detonation? I'd assume so.

I hope nothing got hurt...I need to get over to a dyno ASAP this weekend!

no that wasn't detonation....i'm not sure what your pop was, if you had no other issues after that. Detonation on your setup should only occur under a load (driving down the street with the pedal mashed) and the sound is a gravelly grrrrrr noise that goes away when the load drops off....which is the problem i'm still having!

shake a coffee can full of marbles, thats what detonation sounds like

or even two pieces of metal banging againts eachother sound kinda like it (like what a lose heat shield on a converter)

detonation is not the problem.... did you blow your discharge tube lose? I had that problem with a loud pop

Still think its running rich? If so maybe it was a little backfire.

AmBo · Aug 27, 2006

It might be. I gotta get over to a dyno to ease my mind. I'm going to take her out for a spin now. brb

AmBo · Aug 27, 2006

Just took her out and all seems fine...odd. I gotta schedule a dyno appt this week.

nwapache · Aug 27, 2006

so when you are maxing boost, you aren't getting any strange noises? lucky bastard!

the98stang · Aug 28, 2006

prolly a backfire from running too rich. detonation would be constant and sound like marbles inna can...

Nope. The only noise I hear when maxing boost is the screams from the passenger. It sounds almost like a "WOOOOHOOOO!" or "HOOOOOLY SHIIIIIIT!" It depends. I'm still trying to debug what it is.

nice work.Tim responded to my help message this morning by telling me my problem isn't timing...so I have no idea what the heck is wrong on my car, grrrr

AmBo · Aug 28, 2006

I thought you said you were getting detonation?

nwapache · Aug 28, 2006

I've still got detonation, but tim says its not from timing....maybe a faulty part, or something installed incorrectly...I have no idea what to do right now. I've got an appt for a dyno run 2mrw but not a "tune" so i'm going to go over everything again today, and hope I catch something obvious

AmBo · Aug 28, 2006

That sux so hard bro. Not knowing where to look is always a kick in the throat.

nwapache · Aug 28, 2006

yeah, tell me about it...esp since I know my car should be out there stomping ass right now...so i'm going to re-check all my connections, pull and regap the plugs, and hope for the best. keep you updated

I didn't do any bolton's prior to the cobra killer! I just built up the suspension a bit and did all the pre-centri mods that I could do without wasting my money.

Thanks to :SNSign: I was able to plan out my plan of attack for my car perfectly. She runs beautiful and loves to get romped! However, the 10mpg I'm pulling on this tank isn't so great.

wow I can't beleive all the problems the blower guys are having.
Hmm
nitrous 8 hours to install.
zero issues
stomping most s/c gt's I run into

Real men get blown, babies play with bottles.

My power is always there. The idea of "I have to refill my power" doesn't sit well with me. Neither does the idea of a faulty jet blowing my block.

To each their own!
