2000 ssei noise under full throttle s/c side

Ok first off thanks for any advice today . I believe this is my first post on a computer other than my phone.. I will try to explain this issue as best as i can . fair warning i have bad grammar and spelling, so please bear with me . The car is a 2000 ssei all service up to date before i started modding . In fact there is a new coupler so that is out of the question as far as where the sound is coming from. I have the torque app and have been scanning all types of things and notice the kr most important has been spiking up to almost 10* but not all the time so im thinking that this is a false knock sitcho.. from a stop top wot i get maybe 4* but if im rolling around 40 and mash it i will get a spike to about 10* and when i reach wot im receiving a loss of power and a zapping noise or almost like a tazzer. today i will pull off the belt and check the pulleys and see if maybe it a bearing . Please is there any other things i can check that might fix this . One last thing is that i have been trouble free until about a mth after pulley drop to 3.4 . If it matter i have always ran 93 octain. I can get a sound clip of this is that w

Also could it be that's not right enough with the3.4 sc pulley. Its therea wayt to tighten the a belt or tensioner.

Did you change the belt when you went to a 3.4? You need to get a smaller belt or a larger tensioner. Intense has both of them, I have NFC what the applications or Part numbers are for either.

KR used to spike up on my bonne when I downshifted, I got up to 7.2* of KR one time on a downshift from 40, but I was stock and had a shot motor mount. That KR is still kinda high even for false knock, but I may be wrong.

As far as that noise, I would check the belts, It could be slipping at the high RPMs causing the loss of power.

EDIT:

Just saw Ed beat me to the post lol.

I'm looking fora belt. Iguess the stocker is just two big now. Hope that will stopit.

Iirc the smallest you should go with a stock belt is a 3.6. Definitely get a smaller belt on there

Yes, a 3.6 uses the stock belt and tensioner pullies. Smaller will need a smaller belt or a larger tensioner pulley.

who's got the best deals around for that now. Gb6715 rt

Not very many places sell the gatorback, so you're limited there. If you find the application for it, you can cross-reference it to all brands/lines.

Intense has the variable sizes, yes no?

Yes.

So I picked up a belt from napa yesterday, while switching the beltI did lookat the pulleys and did notice the front tensioner pulley had abouta 16th of play in it . Does this mean it bad? Will this need replaceimg rt away? Something tells me I could be getting knock retard from this. Also how are we mounting our pcm with a fwi? Any pictures. I don't think the pcm trays fit under there.

EDIT+ after taking off the belts im noticing that the other sound im hearing down there is the ac condenser. Can i just get a smaller belt and go around this or do i have to have a bypass pulley? Any help would be great i have to work tomarrow and if i can fix this today while its apart that would be a blessing.. thanks in advance

PCM tray that Intense sells is what I got. It's from a s10/blazer, iirc.

You'd need a delete pulley for the A/C condensor, if you wanted to remove it.

I have my PCM on the Intense tray right in the stock location, where the airbox used to be. It's snug against the one radiator hose, but it's not a big deal.

Well the noise has not returned but im getting some degree of knock . What are the first few things i should check. Keep in mind i have not done a case relearn yet an heard that that would fix a few *.

I think the lack of CASE relearn will just give you misfires if it becomes a problem.

Lets take that to a different thread JEzze, your knock has nothing to do with your S/C belt slipping. I'm guessing it's legit knock, due to your setup. Start a new thread with all pertinent mods and how much knock you're seeing and when.
