I think Ultimately the k26 can handle more. However, I believe the k26
that is in Audi's vs the k24 Audi units, the k24 can handle just as much but
still keep the power coming in much sooner. In response to original post, I
think it can spin faster, safer. THat doesnt' always mean more power either

Agreed. However, it is odd that both of us are quoting NEd and yet we
differ in out responses. ????

Yes. I knew that. Again, got that from Ned. Speaking of which. have you
ever ridden in "THe Beast"? What a ride. I rode around in that for a while
with him and what is really amazing is that at 90 mph, it feels just like a
"Normal" chipped 5ktq at 50. Or maybe like a stock 5ktq in 1st gear. It didn't
seem to car how fast you were going, just kept on going. ANd the "ONE" time he
punched it in first (wise to prolong the life of CV joints and Clutch) my hat
flew off and hit the rear window. Wow. It was over in about 1 second or less
though because then he had to shift.

THis is contrary to everything he has told me. I dont have a chart like
this but he firmly tells me every time we talk that the k24 can do more. He
says the stock turbo in 5ktq (k26) is only good for about 230 - 250 hp MAX.
THe k24 in 20v will do 275 fine. Anyhow, the max power is close either way but
the spool up of k24 makes more power available.

I have not seen this on a 5ktq but on the UR-Q the IC makes a small
difference but the k24 made a huge difference.

THe spool up on RS2 isn't much better than k26. It is a little better but
for 2.0 bar I would stick with k24. That is what Ned and a few others
Recomended to us. Dont bother with RS2 unless 2.2 or above. Also, you can get
the Audi Sport Tuned k24. THat is they way My friend Adam will go I think.
I would like to hear a report on the IC change though. IF you run 2.0 bar,
this is highly recomended anyhow.
