1.The PES supercharger boasts +270HP and should be shipping soon..has anyone used this or have impressions on the application? Can you have this package even on the A4 Q Tip given the 240 max rating?<br>2. Does anyone have a difinitive 0-60 time for a '98 A4 QTip? The mags either dont list or have it all over the board from 8.4 - 9.6. I cannot see spending $35k on a car with that kind of subpar performance.<br>Lastly, what performance (0-60) do any of you realize with the KO4 mods on the 1.4?

Steve,<p>Two questions for you:<p>1) Have you discussed this with Tony. Since it seems to be of great concern to you, I'm just wondering whether or not you discussed it with PES?<p>2) Wouldn't you think that the transmission ratings are conservative? I assume they build in a significant margin for added safety and reliability measure. As far as I am concerned, anytime you add almost 100hp to an factory-spec engine, you are assuming some degree of risk. <p>To me, the tranny is just another piece of the overall risk equation. I really think it comes down to *how* you will be driving it. If you constantly beat on it, you may run into problems. If you drive it smoothly and use common sense, it will probably last longer than you own the car. <p>I am no expert, so feel free to disagree! ;-)<p>Mike (30v manual - soon to be supercharged)

1) Have you discussed this with Tony. Since it seems to be of great concern to you, I'm just wondering whether or not you discussed it with PES?<br><b><br>Well, as a tiptronic owner & as someone who supercharged my last vehicle (which was also an automatic), I am very interested in making sure that people understand what is involved. This poster obviously knows none of the issues by his line of questioning....therefore, I want to help out by at least letting him know of the risks.<p>I am all for supercharging...I'm actually pro-PES because of your posts & his write ups. He obviously has done his homework, & from the write ups, it looks like a very inclusive kit.<p>However, I am not in the market RIGHT NOW for a supercharger. Especially when no one will PUBLICLY address this issue. It is an important issue for ALL tiptronic owners who are considering ANY power-adders. Yet, the only response is a request for a private discussion. I'm sure everyone saw that as "something to hide". Whether or not it was, is a completely different issue. It looks spooky when people won't address the issue for all to see...<p>My last vehicle had a built in transmission cooler (don't think the A4 has one...could be wrong)...AND I was advised on the methods for using the s/c: (1) get an electronic shift kit (similar in theory to what Garret does); (2) Don't run into boost (not even 1/2 throttle) for the 3-4 (4th was OD) shift; (3) get fuel pressure & boost gauges to monitor the system; (4) expect a full tranny overhaul sooner than usual. Didn't concern me as much when a tranny is $2500 new & $2500 for a HD rebuild with HD torque converter from the aftermarket. I don't see those items for a ZF 5HP19....and I think we're in the $10,000 range for a new one right now.<br></b><br>2) Wouldn't you think that the transmission ratings are conservative? I assume they build in a significant margin for added safety and reliability measure. As far as I am concerned, anytime you add almost 100hp to an factory-spec engine, you are assuming some degree of risk. <br><b><br>Hmmm...conservative, maybe...but not 20%...The days of safety margins like that are LONG GONE. Sure, when engineering tolerances were less well known...but now cost rules. It COSTS less to know what a product can handle and design for that number IN ADVANCE.<p>Ok, let's say it's not a safety margin...let's say it's a reliability margin that ZF came up with to keep from dealing with claims from people who abuse their product...I could buy some a margin there, but I doubt 20%....especially when there are DEFINITELY reports being circulated (authenticity verified by Garrett's website itself) that these transmissions are failing....check out his website for details...he claims none of the units he's been involved with have failed. But the fact remains that some units somewhere are failing in modified service.<br></b><br>To me, the tranny is just another piece of the overall risk equation. I really think it comes down to *how* you will be driving it. If you constantly beat on it, you may run into problems. If you drive it smoothly and use common sense, it will probably last longer than you own the car. <br><b><br>Ok, but with a stick, you're talking clutches & manual tranny overhauls. Have you ever looked at the auto tranny aftermarket? It's littered with UNBELIEVABLY high prices, small tolerances, rip-off artists, and unfounded claims. It's pretty scary & sending some poor A4 owner out there because he wanted more power, but didn't understand the risks (which, as I've said here, are much higher than with the stick) is just wrong.<br></b><br>steve

Do the 1.8T and the 2.8 share the same Tiptronic tranny? Reason I ask is because there are two people who have fried the Tip in their 1.8T which were equipped with the K04 upgrade making about 235hp. <p>Ali <br>1.8T 230hp

Jim,<p>I just searched the archives and could only come up with a post you put up which mentions that you did talk with Tony and that the supercharger is compatible with the TIP. I didn't see any content beyond that. I must not have found the post you are referring to.<p>In the archives, I did see that you have a TIP and were interested in the supercharger. What is the status on that. As a TIP owner, are you still interested in the kit? <p>Mike

A transmission is designed to handle torque in the grears, shafts, clutches and bearings. The bearings also are designed with speed in mind (velocity * load). With these two points in mind, one can see the lifespan picture. I would bet the real limiter is the clutches, both stick and slush box. The bearings only get momentary shock loading as a design limit, are well cooled and lubricated and usually way overdesigned. The gears are also designed to take shock loads so this is of little consequence. The tranny is not designed with weight limitations being prominient (as in aircraft design) so I put safety factor at over 2 based on yield point. This translates to a nearly infinite cycle life with ferrous materials.<p>Plan on more freq1uent servicing with the supercharged tip.<p>krj

Obviously ZF is the manufacturer of of the ZF 5HP19. What does ZF stand for? Must be in Germany but not affiliated with Audi, VW, or Porsche? Thanks for any info.
