Question Burst Rattle?

What exactly is burst rattle? My friend was telling me it had something to do with the gears in the transmission. He is thinking that my "rattling sound" when I lug the motor is really this burst rattle instead of detonation.

Anyone fill me in on this?

I have no idea what burst rattle is, but I do have to ask you why in the hell do you lug your motor?? If you find changing gear that difficult why didn't you buy an automatic?

actually, if it was as simple as changing the gear I would be happy. The motor tends to make this sound (which I think may NOT be detonation like I previously thought) whenever too much throttle is applied for a given speed in a certian gear (luging). The motor also makes this same sound on WOT blasts thru the gears. I have no hesitation, so I am beginning to rule out detonation.

I was running 91 octane, and the dealer set the timing back some after I did have detonation while climbing hills and hesitation during acceleration.

I am told this is burst rattle is just a change in momentum in the gears in a transmission and is normal. I have never heard it before, and the dealer claims that there is no sound (just like my transmission doesn't clunk).

I just want a little more information about the subject before I go back to the dealer to have them tell me a certian sound does not exist. I am hoping they will let me take another 02 GT on a test drive so I can see if this is a normal occurance or just my vehicle.

I've never heard one make that rattling noise before when at WOT, but I do know what you're talking about. I think it's more to do with the clutch and/or throwout bearing. My 88 did it, and I then I put a new clutch setup in. Gone. Probably, it's the throwout bearing/sleeve or the pilot bearing.

My 99 T45 makes the noise a lot more than any T5 I ever had. Usually when you slow down and shift into 2nd or something to accelerate again in traffic and give it significant throttle?

I also have the exact same problem. I've posted here about it before, and most of the replies thought it was normal T45 noise. Apparently the T45 is a very noisy tranny):
