To me it sounds like the bearing on one of the pulleys might have gone bad.
I was thinking you guys were on the right track... but then I turned the engine off and the noise continued with the key in position 2, so it can't be any of those rotating parts...Last time a timing belt was changed? And was pulleys changed with it?
Sounds like to me it’s the idler pulley for the serpentine belt. It makes a sound like that when you spin it by hand with it off. 2 12mm bolts pulls it out and you have to loosen the belt as well. That’s what I’d put my money on. And if it’s not there’s another pulley at the bottom of the power steering bracket as well
Man, I'm so damn excited!!
Dis gonna be good. What's your plan for tuning it?
Seems like a solid plan. I think I'd let the pros handle the tuning.Man, I'm so damn excited!!
I'm thinking I'll send my M4.4 ECU from the S70 to Aaron and get the stock manual 850R tune loaded up. In theory that would be a nice 10hp/38tq bump for ~$130. I may spring for the tune-it-yourself option with the manual R tune loaded as a base, but I'm not sure whether or not I want to get into tuning
That seems pretty plausible, I'll check with Aaron once I get that going. I guess the main difference would be that the manual 850R used a 16T as opposed to the 15G, and I think the S70R did as well? That or an 18T. I think I'll eventually rebuild and swap in my 16T for this car some time down the line. I do have a manual throttle cable so that's been accounted for!Seems like a solid plan. I think I'd let the pros handle the tuning.
I heard a rumor at one point that the stock R manual tune was from a S70R but I have no idea if that's actually true or not so I'd verify with Aaron what "stock" means in this case. Even if it is set up for a stock manual 850R, it's still different from the automatic setup you have. Grab a manual throttle cable, too. Yes it's different. It uses the other cam on the throttle body.
Right right. I sold my white injectors last year which I'm now regretting! I'll see if the guy has even installed them lol, maybe he'd sell them back. Shouldn't be hard to find a set if notThe automatic S70R used a 16T, but I think the manuals used a 18T. They also had white injectors. Not what, if anything, else is different.
