I once had the same problem on a different car where I had to take the caliper off, put the bleeder screw in a vice, and use a pipe as leverage to twist the caliper off of the bleeder screw. I'm still surprised it didn't snap off...

I will say that adding the SC has made tuning the engine a bit harder as i have loaded a base map and the car runs and i can drive it but i can't hit the throttle fast or it stumbles i need to get out and take it for a ride and log what is going on with my laptop and maybe turn on the auto tune on MS tuner studio hopefully i can read some more and get this sorted out .

today i looked to see what boost i should be getting with my blower setup i have a M122 so it is a 122 cubic inch supercharger and with a 6.5 crank pulley and 2.625 i should have 23 psi of boost oops i need to change that blower pulley to the 3 inch that drops boost to 17 psi i used this calculator with engine efficiency of 90 percent and supercharger of of 80 percent http://performancetrends.co...Boost-Calculator.php

today did some more work on the fuel map and i am getting it better as it is not having the violent swing from lean to rich with small movements of the throttle i still can't just floor it but i might go back this afternoon and do some more tuning

today was a good day even though it is not running perfect it just seems so good to be able to take it for a ride and could even drive it to the dyno so i could have it tuned but i am having fun learning how to tune efi and i like the challenge of doing it

I went out today and ran it up the road and just feel it is not the best place to be tuning since i need to at some time do full throttle runs and that is going to get me a trip to court and a fine i bet so i will just spend the money at the dyno

It feels so good to drive the car even though it is not 100 percent done or running correct now i see all the work is paying off i can see things i need to repair and things i think i just need to change but for now it is a driver and as it gets tuned and i get a interior together and repair body issues it really is all good especially when i get to puff my chest out and say yes i built it all good or bad i am a proud owner of it .

Wonder what the 0-60 is going to be like? I'm still enjoying following the AUDI build and progress and it seems like a solid decision to dyno tune it. Because of this thread an Audi 2.7tt (380-400 hp) build is in my future.

Not sure how quick it will be but even not tuned well it pulls hard and i can't slam the thing to the floor as it just stumbles due to it being so bad but i drive it and tune it over and over so it keeps getting better i need to get it the best i can before going to the dyno

Today i think i found my belt problem in a strange looking idler pulley as it feels out of round and has the finish worn off in one part of the pulley but it is not worn all the way around the pulley it is about half way around

well yesterday the fiero got me with its crappy fuel gauge ran out of gas with it saying just under 1/4 tank but good did come from it as i thought something else happened it tossed the serpentine belt and when i got that back on i thought i had flooded it so i pulled the plugs and found i was getting strange reading cylinder to cylinder so i did more looking into it i only had 4 injectors firing i did not turn on the other injector drivers so it would run semi sequential so i turned them on

41 pages and one thousand six hundred and twenty (1620) posts so far - and still counting....!

Is there a technical question in all that which has - or hasn't - been solved? It's getting a bit hard to search.

Maybe engine man should be aiming to write a book? Or perhaps PFF could create a special area in the forum where he can keep a daily diary/log?

Maybe I need advice on how to prevent my tongue getting stuck in my cheek?

Brit, eh? Huh. Scot, to be precise. Sometimes described as a "Jock". But I gather that has another meaning across the pond.

But enough - we risk going off-topic! And that wouldn't do at all.

Onward and upward. The A8 experiment is a brave, if complicated, one. Respect to Mark/engine man for the effort. We all wait with bated breath for the final outcome of the epic story, where everyone lives happily ever after.....or drives off rejoicing into the sunset?

Sure, but you're still a Brit. You've just narrowed it down, is all.

No dispute: I'll answer to both (and no intention of voting for ScotNat independence!).

Well today i took it for a ride and it runs better now that all the injectors are working not sure 1st gear is even worth having as it seems to be time to shift before you know it and i did not even get it to the floor i would say about half throttle and 6000 + rpm's are there before you know it and this is a un-tuned engine that is still going rich but all cylinders are firing . i also worked on pulley alignment and shimmed the supercharger pulley and 2 guide pulleys that make more belt wrap on the supercharger pulley i am not sure the clutch or transmission are going to last a real long time as i was told third gear is really weak .

Well i went to the dyno and he got the engine to run better but i need to do something about the belt driving the blower as it is a 6 rib and it just is slipping you can hear it and it finally started to shred. he got 1 pull to 5000 rpm with it not tuned it hit 14 psi then dropped in boost as rpm increased due to belt slip i also need to move my air intake temp to after the blower and move the water methanol injectors to after blower so i am going to pull the engine and put in a new crank seal as i have a oil leak up front Marc was a great help and i hope to get back down there soon

i looked at my ignition timing map and he has pulled a ton of timing out and it is set at 12 degrees under boost and that is just killing the power but he only did one run and that was just a starting point i think it will be around 24 degrees or maybe more

Worth the effort to do it again once the changes are made, I say (a paid tuning session). How many ribs should the belt have? I drove a 4.2 S4 6 spd recently and it was pretty enjoyable.

I ordered 2 pulleys toothed t5 belt tooth by 25 mm wide bottom is 60 tooth top is 26 tooth that works out to 2.307 ratio and at 6500 that puts the blower speed at 15000 and that is right where Eaton wants the blower to run there will not be any belt slip now !
