what mods are needed to go beyond 600Hp

I'll also add that I believe the stock mafs will be the limiting factor before the manifolds are a concern

Hmmm...I've got a Wizards of Nitrous kit that has been sitting collecting dust....I think it's time to try it out.

The thing about dyno numbers is they can be manipulated. 1/4 mile is the ultimate test of how a car actually performs. Im more concerned with how the car makes power through multiple gears.

Good info and comments.....I certainly won't be the one to find out flow limits of the manifolds.
But would be in car heaven behind the wheel of a Gumpert.

I'd be in hog heaven with a Gumpert too; however, in a foot of snow, hauling the family around, moving an entertainment center with the trailer, or funding my retirement, I'll have to settle for the RS6

Did somebody say Gumpert?

This is my understanding also. Stock MAFs are nearly maxed with my K04 based hybrids.

does jason @amd work on your car? He is tuning my car in a few weeks and we will be working on a maf solution.

**Avus-RS6** · July 14th, 2014, 23:29

Yep. I've seen your engine at the shop and get the same info as you from Petek regarding MAF being maxed.

**4everRS** · July 15th, 2014, 05:20

I would like to know what information he is going on to say the mafs are being maxed.

**Korben007** · July 15th, 2014, 06:14

I wanna see!

I'm sure it's easy to find out what blocks the MAF readings/ voltages come from. I don't know personally nor do I know what the readings are on my car, I didn't ask. Our tuner is very trustworthy and doesn't push improvements that aren't needed. When he says that 770's will require a redesigned maf solution, I believe him. I used to log my B5 S4 all the time but I've outgrown that sort of thing.
