I know you've done more then the chip and Borla but they are the main producers of extra kick, What do you think the hp & torque are up to now? Any stats on 0-60 or 1/4 mile times? I am installing the borla to my Garrett chipped TTQ on Sat., was just wondering. It should be somewhere in the 225 TT neighborhood.

By GTech-Pro. And mathmatetically the 225 is 190 + or -. But its too cold now to test 0-60 and 1/4 times. I have some old ones off a TAP chip, pre-exhaust, but the Garrett is a far stronger/smoother chip. And the Borla does make power. But you wouldnt be out of line expecting 6.4-6.6 with chipped Q. I'll have a TON of info towards the end of April or early May on 4 chips and all 0-60 & 1/4 & HP specs before & after at that time. Its not fair to test one at 30F and another at 85F. I'm keeping them all in the 70's for any 'reported' results. And I think I can blow by the 225's HP with addition of the 2nd intercooler. The crossover outlet is in place in all our TT's and capped off. Just a matter of 2 sections of pipe, 2 silicone sleeves and 4 hose clamps to make it identical to the 225. Just waiting on those part numbers from Audi. Cars gotta get here before the part numbers do... and even then sometimes later.

Do you think we can get the 180 hp q's up to 225 spec with chip/exhaust mods? Yeah--you do--so why did I post this?

I think this would put you in the 240-250hp range, but you would have abit more turbo lag due to the KKK04. Other than a few internal engine changes and the dual exhaust of the 225, its almost the same deal.

MNE I know you are planing to add the 2nd intercooler when the parts become avail...could you let us know the cost of the parts and labor and if possible the performance difference. Thanks!

I will let everyone know about the 2nd intercooler stuff soon as I have the info. Due to it being Audi parts I KNOW it'll be expensive. But I talked with my Audi mechanic and he said "no warranty" probs with 2nd intercooler. And Audi will even warranty the original parts for one year/12k miles.

From everything I've been told the KKK04 turbo looks the same on the outside, and has more aggressive blades on the turbo fan to push more air, but at the same time, at low rpms this causes a bit more lag.

I may be wrong, but I don't think the KKK04 looks different from the outside. Please correct me if I'm wrong. A website with a picture would be most helpful.

AND a larger, not more agressively angled impeller. I think any turbo manufacturer would max-out its impellers for volume and efficiency. I would think therefore that at the very least the K04 would be a dimensionally larger housing and inlet with a correspondingly larger impeller. May share the same base flange. And the only reason I believe any of this to be true is the touted lag difference between the two units. I dont believe a more agressive impeller, in and of itself, could be responsible for such a pronounced difference in spool times without some accompanying larger internal volumes. Conversely I would think that a more extreme impeller would reach its compression stage even faster. I just gotta believe the KO4 is a larger unit based on this knowledge. And I'll go even farther out on a limb and hypothesize its got to be somewhere in the 15-20% dimensionally larger area. But I'm out on a limb here... nothing carved in stone or empirical about any of this till I hear from someone that knows or see both units side-by-side.

When I go to get my springs installed I'll ask and see if they know the answer to this.

I just put the question to em over at A4 "performance" forum... they know... post when its answered (nt)

they're hidden when the unit is installed. Hmmmmm
