sporadic engine vibration/start-up
I searched a few keywords like engine vibration and tranny vibration and consulted these threads:

https://www.evolutionm.net/forums/sh...gine+vibration
My issue is not quite addressed in either, or the sticky with rattling issues which i also consulted. When i first start my car, after clutching in, then when clutch is out and the car is in nuetral, while my car raises the rev's during starting, i get a grinding noise. I compare it to the noise you get when your in gear half way and the flywheel is grinding or i assume the clutch is only catching halfway. This issue also occurs during low-rpm deceleration on the free-way but is most pro-nounced directly after start up with a strong vibration felt while the rpm's raise. i do not think it is related to a noisey throw-out bearing which has been talked about before. Any ideas, cars an 05 with a tick under 23k. Never taken to the strip launched maybe twice.
edit: i would also like to add that i am having trouble spiking over 20psi on my 05, could this possibly signal an boost/exhaust leak possibly? dont want to clutter up the forum with old questions, just want a piece of mind that my 33g car is not on its way to "grenading"

I think I got used to the noise my car made, but it did sound like a whine,grinding noise.. I popped the hood and tried to hear it better, glanced closer and it looked like it was the belts... as they spin, they make this whinning noise... Now I dont know how to stop that...? =/
