all I can say is tuning a V8TT can be a serious work out!!

Marc you've got a fun car there, keep it topped off and you'll be fine!!

Another honorable note: Marc I didn't think it was a good sign at first when that statey came running to your door!!

Good thing he got called to something more important LOL

ahh good times, good times

Thanks for the tuning help Myke, I dont think I would have made it to the gas station without your help. Literally! :lol:

So we're driving along: "Myke, the mixture is going lean, I dont get it?" "It doesn't do it when we lay on the brakes and put the motor under load?". "I fattened up the cell but it isn't helping, still lean??".

"Um. The car's sputtering. Marc, are you out of gas?"

:lol:

The Statey was icing on the cake. Pulled me over probably because of the massive nose dive on the car due to shitty front shocks (wasn't really going THAT fast.. I think? :wtf:

). Anyway, we pull over, car smoking a bit from the breather remnants, statey says "This car gonna make it", both of us, nearly in unison "Its running a little rough". Gotta love the stops that result in the statey flinging your license and registration back at you and speeding off, especially when the car you are driving doesn't have an inspection sticker :-o

I never get that lucky! :frustrated:

Looking forward to seeing your machine in person, Marc! 8)

Glad to see you have it on the road Marc! FTMFW!

I do have to ask though...

Sounds familiar to when I was doing the initial tune on my 4000 :-P

Passed the officer going the other direction, look in the rear view to see him putting on his brakes and looking for a place to turn around. I just pulled into a parking lot and waited for him. After telling him what I was doing, he laughed pretty hard and then said all was good and went his merry way...

glad to see the beast is up and running buddy! Gonna be at WG2 ???

Pulled the front end apart on the v8 last night to get to the bottom of a nagging issue regarding the tensioner for the serpentine belt. The belt squeals under load from the alternator and I've discovered that the reason is because the tensioning arm isn't tightening up like it should.

Further investigation reveals that you can disassemble the mechanism leaving two needle bearings inside the TB cover that a little keyed cylinder is supposed to ride on. Those two bearings are seized on both my covers and a spare cover I got from Haydn (thanks!). Anybody BTDT? Part number? Etka only shows a full replacement TB cover :(

So the problem isn't the tensioner damper shock? I've been through that twice now.
But
a break down CAN be found on the ETKA.....illustration 152-10.

I hate to suggest Blau....but, they carry a serp belt "kit".
Or I've seen listers match up the bearings at a bearing shop. Like I said....I've never had a problem with them...so I never really payed attantion to the correct info.
A search on the audifans V8 list will prolly get you the info...

I always get a little fidgety when someone says blau in a negative way. I'm biased towards them, and yet I can't deny the problems people have had.....total rock/hard place :(
