It his on/off valve since his meth nozzle will see vacuum.

You only need one nozzle BT, gonna be enough?

It's going to be PWM controlled.
And yes one will be enough ... it's a 12 GPH (756ml/min) nozzle.
But remember... I have next to zero knock as it is already lol so it's going to be awesome

I run dual 7s :).. Barely in full boost though so don't really go through much. The day of race wars is the NHRA supernationals.. I usually go to that to get my VP M1 from the truck there. $25 for a 5 gallon drum can't be beat!

Awesome location!

Time to peg that boost gauge :)

I didn't take the Audi to work today...
The last couple mornings when I started the car there was a slight rattle from under the hood that went away after a few seconds... Everything seemed normal so I didn't think anything of it, figured it was just something under the hood.

Then yesterday when I got home I noticed a worse rattle coming from the engine... it was coming from under the passenger side valve cover... right in the tensioner area... Uh oh...
Checking Block 93 showed the passenger side cam was around -14 degrees.... not good.
So I decided to play it safe.... this afternoon I pulled the front off the car, figuring I'd pull both valve covers and double check timing.



As soon as I pulled the passenger side valve cover I saw this laying at the back next to the timing chain...



The damn lower plastic piece on the tensioner exploded!
I guess now I know why the car had rattled and been down on power off boost the last few days... I'm going to say I was very lucky nothing bad happened!
I'm also glad I'm very cautious when it comes to new noises!

So remember, rattle under valve cover is bad!

Tomorrow I'll replace the passenger tensioner and put everything back in time... kinda glad the track was rained out tomorrow or it could have been very bad!

[TweetsS4Estate]

Yeah, to say the least, wow!

[slow ride]

Replacing the whole thing or just the pads?

[D Lo]

It's damn good you listened to your instincts and I'm glad no major damage has occurred. Keep it going :)

[britishturbo]

I think I'll go buy a lottery ticket now lol.

[shorterthanrich]

So many disasters avoided so far! Lee here is teaching us all that it's good to be thorough...

[bigern45]

Is that an OEM snub mount I see?? Tee-hee...

[britishturbo]

lol have a brand new APR one to go on :-)
But yes haha

[AudiSportB5S4]

Glad you caught that!!

Give the guy a break he still is on the stock pogo sticks too.. Lol

[britishturbo]

Glad you caught that!!

Haha. for now ;-)

[bigern45]

Lol- luckily my cam tensioners have 170+ thousand miles on them, if one goes bad, I sure as hell know who to call....

[britishturbo]

So when I pulled the cams and tensioner out this is what I found lol:



Apparently metal on metal isn't good lol:


The rest of the plastic wasn't in the head... only that one piece... sooooo no prizes for guessing where it all was lo, yepp... in the oil panl:

[britishturbo]

Going to go pick up a new tensioner right now.

[laserb5]

Wow man these tensioners just aren't cooperating for you. Are you getting new from the dealership or another source?

[bigern45]

so i guess you just dropped the pan. glad you found it all and there is no guess work at this point..

[britishturbo]

Brand new one from my friend Patrick in State College. He usually has most things in stock.

[britishturbo]

so i guess you just dropped the pan. glad you found it all and there is no guess work at this point..

Yeah I had already drained the oil so I just dropped the lower pan.
Its crazy the mess a little piece of plastic can do lol.

[Hyphy]

how long does it take you to swap out the tensioner?

[britishturbo]

how long does it take you to swap out the tensioner?

Just the tensioner can be done in a few hours

Kinda off topic question. How do you make ME7logger not look like a mentally challenged kid had a connect the dot frenzy (how can one make it collect data quick enough create smooth graphs that aren't jumpy)

[Don Supreme]

What you are seeing is ecux_plot's graphing function. The lines are not smoothed in same fashion as the markP excel templates. The logger is not the issue.

Ok, I know for sure that the IAT sensor doesn't log like that.. So it has to be the data recorded no? It will Drive me crazy not to smooth this stuff out. Do you boys have any idea how to make it look better?

Just take the raw log data and stick it in excel if it bothers you so much.

[TweetsS4Estate]

Just take the raw log data and stick it in excel if it bothers you so much.

And create a "Reid C" folder.. Yeah maybe.. Then I could set the rawness of the graph possibly have lines to fit 02 sensor averages and such for those W/O widebands..

[britishturbo]

My IAT data is smooth... *shrugs* lol
And you can always log from me7logger in "mark p style"

Anyway I've been using something totally different lately... ;-)

Hahaha get it AWAY! Ahhhh! Lol it's like watching a heart rate monitor.

[obijohn22]

Lee, are you going to have your whip back together for race wars? I wanna see it run man!

Should be fully up Wednesday lol

[obijohn22]

Cool. I am going to give you a chance to show me your taillights. And I expect to see them. :)

Haha but she's so slow lol

I'm thinking of getting "SLOW S4" as my licence plate lol.

[Delmed83]

Damn, you had just replaced that pass side cam adjuster, right?

[britishturbo]

Damn, you had just replaced that pass side cam adjuster, right?

Yeah with a used one...

[britishturbo]

No work on the car today since its mothers day lol.
I figure I'll get the motor mostly back together tomorrow evening.
