It wasn't the width/diameter that was a problem, it was the length of the TB's neck that stuck out past the studs. It was barely wider than the hose clamp itself, so it kept slipping & popping off

lol that thought actually occurred to me as I was typing my previous post. Like I said, I haven't had any problems not having the clamp, but if I do I'll use a strong zip tie

I guess ill just run in without the clamp and cross my fingers

mikenacarato · 05-05-2009, 11:45 PM

get 3 more bolts like the one lower left bolt and replace the 3 studs.

PHXDEMON · 05-06-2009, 12:16 AM

Just finished the install and holy fucking oscillation

form 1000-3000 rpm from a cold start. I tried driving around a little bit and it started jumping up to 4k on idle

and a CEL. How long does it typically take for the oscillation to start smoothing out? It's too late here (9:15) to mess around with it more. Don't want to piss off the neighbors. Any suggestions?

MGargano · 05-06-2009, 12:20 AM

It took about 2 days or so for the oscillation & CEL to finally go away

PHXDEMON · 05-06-2009, 12:28 AM

I am doing to leave the battery disconnected overnight incase 2 hours wasnt enough.

Did the oscillation slowly smoothe out or did it just stop out of nowhere? How much driving did you do in 2 days?

MGargano · 05-06-2009, 12:38 AM

I got oscillation at cold idle as well as intermittent CEL for the first two days, then both just went away completely. All I get now is the high (3,000 RPM) cold idle and better performance. I only did local driving during those first few days, no highway or any heavy pushing.

Damn I was still gettingm oscillation and my motor was getting pretty warm. Is there an an idiot light that turns on if it starts overheating?

PHXDEMON · 05-06-2009, 01:27 AM

WTF I just hooked the battery back up and started it up again and my idle was perfect with no oscillation

Hopefully it stays that way. I didn't want to even take it around the block because I have had about half a beer and their are mad cops out for cinco de mayo. Hopefully I will have a nice drive to work tomorrow

Don't be surprised if the oscillation comes and goes for the first couple days. This happened to me and I thought everything was fine, then I got oscillation on the next cold start. Just be patient and give it a few days to work itself out.

No clamp for months now on mine and no problems.

Yeah it came back

Just out of curiousity, are you guys doing the coolant bypass? I was considering doing so unless this changes the way it idles. The 3k cold starts for 1 minute is all I want as far as weird reving goes. Dont want the bypass to screw with my fine idling.

I did do the coolant bypass. Drive to work today was great

. I actually don't experience the high cold idle everyone else is. My cold idle is around 2k RPM just like stock. I did hower buy my TB from M911gt on here so he may have fine tuned the idle screw. I think if anything doing the coolant bypass will make it idle better
