Marc has the ECU right now. Slowly moving tools over to the new shop. Moving couches into living room today master bed tomorrow. Starting bathroom tile on Sunday then tape and texture. Then the kitchen...
Actually I get a break from remodel all next weekend so providing no more electrical gremlins. Ill install em then. |

go local AJ if you can on the top mounts...you must have made some big promises to the misus - I promised mine that I'd be racing and she'd be lucky to have a roof over her head - what a DICK! - but she married me anyway...
John - what about some pic's of your new diggs eh? Can you tell the rally car is broken and I have time on my hands 'cause I'm not rushing the repairs 'cause they're going to cost me a butt ton of $$$ ??

Well it's the house I bought way back in 01 but that I've rented out for the income. There's a big empty lot as part of this whole shebang and we went thru the whole process of sub-dividing it and so now that is a separate lot and all permitted and gas and sewer and water stubbed in and we worked with a local architect (who came around to have me make suspension for his Focus---but I talked him out of it and encouraged him to refresh his existing Fiat 131) to design a smart green house.....but that didn't work out when we got to the construction loan part...So we went back to the original plan when I bought the place: Live in the apartment, rent the house, sell the property and pay down the loan... Then it turns out my sweet wifey's brother in Bejing decided he wants a house in USA so he's buying the lot AND the plans and is going to build the house..Cool! We're in closing for that at this very moment... When we're done we'll have a total loan left of about $29,000 and a mortgage of around 3.2%---Cool beans....THEN we'll move into the house.... And then with a total of about $300/mo expenses I maybe can feel justified in spending a bit to go drive before I'm toooooooooooo old... What's the big que paso wif your carro?

Don't want to hijack AJ's thread - but it is Audi related - so what the hey...
Last rally we blew yet another turbo - why? here's the theory: a) boost host going to the waste gate frequency valve popped off b) This caused turbina to get over excited c) while over excited, oil pump may have cavitated over a jump around a corner, dunno - starving said over excited turbina of oil d) as you know an over excited under lubricated turbina gets all kinds of testy e) turbina pukes its bearings and carrier parts, some into the oil pan some into the head f) oil pickup sucks up said bits into oil pump g) oil pump reduces pressure due to bits jambing high pressure piston - but of course not enough to make the big holy shit light go-off So I finished the stage, with no turbo and a NA 20v. Crank needs a polish or a new crank Pistons need to be replaced Valve seats adjusted Cylinders lightly honed and of course a new turbina with an accusump boyfriend so when she's excited she'll always be properly lubricated... and that's my story... |

And what are you stinkin pour les pistones? fourgé? (this is your chance to get something you want...and I just happen to be a CP Pistons dealer....) prenez le chance, c'est seulement l'argent!)

ok - here's the way I'd be stinkin aboot the whole deal:
a) This is a restricted moter - what is there to gain to put the forgies in it? b) Audi panzer pistonies are pretty darned stout as they are good to 400hp c) Rods are good too, but they have stretch bolts, and ARP bolts require machining the rods. So, I happen to have 2 sets of forged I-beam rods on the shelf, one with all good nuts and bolts - I'll be using those. Here are the results - how would des forged pistonies help? |

Well maybe not at all.. I dunno what the Howdy pistones cost, don't know what the available compression ratios are....but back when Robert Gobright used to visit occasionally we were looking at available cast stuff for his Fau Vee and seeing what sorta mix-n-match thing could be pulled off and we'ze were both shocked---SHOCKED at what any of the "usual suspects" pistons cost....like over $400 for 4 cast things that really weren't really what we wanted---ya know they'd "be OK to pretty good" but not "high performance". Over $400 and that was for a fawkin Vee Dubya... Now you know that since it has to have a stinking restrictor so people can pretend that it limits something other than Horse Powerz, it will never be happy to rev so if it will only do happily say 5000, then better make it do all the Horsie and Foot/Pounds BEFORE 5000... And anyways großes Schwein wie ein Audi must make LOTS of torque.. And how do you make torque? Engine volume x corrected compression and boost is just another for of compression effectively. Glücklicher, die großes Schwein hat ein motor that is a good candidate for lots of compression AND lots of boost thanks to the small bore diameter it has... So if you wanted to optimise the comp and booost you can do that easier with custom pistons than fiddling with off the shelf stuff that may not be what you want for the unique requirements of a restricted motor... And remember the nicest thing with forged pistone is A) they are stronger---so less likely to fail, and  if things do go badly wrong the fail nicely, they don't shatter and fall in the sump---and leave the rod whirring around by itself doing heaps of evil things...I've had some cast pistons---same brand as in die großes Schwein Audi---fail and shatter and it wasn't purdy what a rod twirling around with no piston on can do in 1/100 of a second.John Vanlandingham Sleezattle, WA, USA Vive le Prole-le-ralliat www.rallyrace.net/jvab CALL +1 206 431-9696 Remember!

Are you heart set on a 20v audi? why not look into a newer design 20v or an ABF-T… or or. |

The AAN pistons, which are going into this motor, w/the 20v head offer a 9.3:1 comp ratio - we can run 26lb of boost on 93 octane pump gas - what would be a target for comp ratio and boost be given 32mm restrict? Displacement is currently 2.2l - so could be jumped to 2.5l and still fit in the rewls.. A set of new stock pistons are $600, set of forged is $700 
Tell me more about what you would do to improve this configuration?
I've considered the 07k - all aluminum Audi 20v, believe it to be 2.5l - but just to get the motor setup for loongitudinal duty would require about $4k and many hours of re-fabbing shnizle - for what gain outside of weight would I get for the $ and hours? Remember - I'm a classic grass roots guy, this particular catastrophe will turn a 4 race season into a 1 race season - the pot only has so many beans in it... |
