ISFXXX

i came from a APR stage 2+ b8 s4 and it really depends on what tires and wheels its running, when i had my stock wheels and michelin super sports i would walk my roommates 392 challenger, after bumping up to 20's and not so sticky falkens... i couldn't keep up in the s4. I got my isf about 3 months ago and my roomate and i have run about 15 or so times from a roll and a dig and he's never even come close to the isf. so all in all i would say stage 2 s4 is even with stock isf. I just couldnt deal with the audi community anymore lol went through 2 clutches and a trans in that pos.

my 2 cents; Audi repairs long term will cost you. IS-F being a toyota is more dependable. Hence i pulled the trigger on one recently.
But audi's are knowing for giving you all the cream for much lesser price than BMW or Mercs and they throw quattro in for fun, which in 4matc will cost you another 5-7K.
Some cars I was looking at before I pulled the trigger on IS-F were
CTS-V (which i still plan on grabbing next; strictly for tunning)
M5
and C63 AMG (4-dr)

Congrats on the F, Is your ISF stock? I have a lot of 392 challengers and chargers in my area. I haven't ran one yet but I would like to know. I know they're really heavy...thanks!

I ran one with a tune at the drag strip. Audie have launch control from what I remember his 60ft were 1.7s mine were high 1.9s . We trapped same speed but he was quicker due to his better launch control. He was in 12.2s I was 12.7s. Now that a proper ecu tune came out for the Isf this will be very close . I believe the guy told me if you use launch control more then 5 times on the Audi the warranty is void . But I guess there is a way to reset that as well

Just uploaded as I had this on my phone

Not sure if this is going to help you but my friend has an rs4 tuned with headers and exhaust vs my isf with a cat back, and he doesn't stand a chance on a rolling start.
Also, my other buddy has a 2003 audi rs6 (v8 4.2 twin turbo 450hp stock) and again, rolling start from 2nd gear he gets smoked. As soon as I switch to 3rd, isf starts to pull on him and it doesn't stop.
He just got a tune from eurocharged so we're gonna have some fun this summer lol

the video is of a friend of mine who briefly had an ISF. I'm the one shooting with his iPhone, sorry for the poor quality. I think he's got a pully and a tune. We made the visit that day as he has been in the process of tuning his car. Sending data logs back and fourth to his tuner in Michigan.

I have a stage 2 S4. The latest APR revision is pretty stout. I am going to move back over to Lexus. I would really like to try the S4 out against an ISF.
