AAN bottom end internals

Chicken and egg scenario

In reality you going to get to the torque threshold for the rods before hitting the bhp/rpm limit via boost spikes or running at high boost levels.

How many cars here actually go beyond the Audi rpm limit in reality and hit 600 bhp on stock internals?

Edit: This is a mute point as the stock pistons would probably melt around 500 bhp

Well, by my calculations you could get 500bhp@~6000 rpm, and 600bhp@~7100rpm, which would equate to 600Nm in both respects.
Whether you would want to risk it is another question.
One sniff of detonation or a boost spike and it would be game over.

What power can these bottom ends take before steel rods, ARP bolts etc are needed?

BHP and Nm

There is a difference between needed and advisory.
Who wants to see if my calculations work in real life?

And yes. Stock pistons are good for at least 550bhp, I know someone with a BTDT.

Bloody good pistons Audi make then! We'll let S2_Bo test your setup

If you can't afford a full rebuild with new pistons and rods then save money for a couple of months more and do it right the first time. You'll sleep better and in the end it won't be more expensive because after a while you'll want more power again and have to rebuild anyway

Definately

Dont forget what happened to SteveH's rods

I'm sure he'll be up for that. Tom can lend him his GT35/40R in the name of science.

So Graham Norton!

Hmm.. Yes. I think Steve established that stock rods definitely won't do 700Nm.

That's the best tip I've heard so far

Stock pistons have been pushed beyond 700bhp but you would need to reduce their CR.
You have to pay to play, performance doesn't come cheap. Do it right do it once
