Head Studs Required?

Head Studs Required?
Are upgraded head studs necessary to run the mile event without lifting the heads? A mile event is coming up in Sept here and I would like to go, but don't want to shoot the heads out of the hood.
Are these necessary? Anything else that may be needed to safely run the event?
Thanks for any input!

Cylinder pressures will not "increase" just because you stay into the throttle for a long time. At say 6000 rpm the pressures will be the same at 30 seconds or 30 min. What will happen is heat will begin to " accumulate" so to speak and if you can not keep it in check it will continue to increase and that's not good.

The good thing is you will have a massive amount of air going through the radiator and intercooler and that will help a lot. I would also box in the intercooler behind the grill. Real easy to do and will make a huge difference in the coolers ability to cool your intake charge. The air will have no choice but to go through the intercooler and be much more efficient. I have done this on every supercharged car and its never proved me wrong.

I have an Aquamist HFS-3 installed as well, which really seems to keep IAT's in check. Along with a trunk tank and upgraded HE I imagine that should be enough? What should EGT's be? At the bottom of 4th to about 5250RPM I am seeing in the neighborhood of 1150-1200F. I assume that is a safe temperature?
At the bottom of 4th I see around 14.5psi with a 185 pulley, MBH Headers and 82mm TB. Im not sure what timing will be.....
Would love to see pics of your modification to box in the HE if you have them.

Sounds like youre on the right track. I personally would consider a meth kit mandatory for any modified car with a PD blower such as these, especially planning to run a mile event.
Play around with the ratios and see what works best for your setup in regards to EGT and RWHP. I personally run 85%-100% meth depending on how hot/humid it is out. Others like more water but that's what works best for me. If the time and budget allows for it get a standalone knock sensor/monitor. That combined with your EGT gauge will be a huge asset in keeping your engine safe.
I wouldn't worry about head studs at the power level the stock blower is going to support except for if you needed new fasteners anyway.

(I'm currently removing my heads and sending them to Shardul for a once over for the this October Texas Mile race. ARP studs are being installed)
The mile race is a different beast all together. For example:
1) Drag slicks don't work due to speed rating requirements.
2) Head winds become a problem
3) Slow staging warms up your IATs before your run.
Registration for the upcoming Texas Mile is August 9th @6:00pm. It sells out in 2 hours. I would love to see someone else from this forum run it. Not many Mercedes show up.

I was running @ 17 psi with every cooling mod known and my heads lifted last October. My IAT's at the end of the mile were @93 degrees and I had a custom tune (for the mile) that was set a little rich on MS109 for safety.

Why would you lift the heads on an AMG that was designed for autobahn speeds? I think you will be fine.
Edit, I see you are modded. But, I still have not heard of these heads lifting off the cars.

Brother, waiting list is open! You would represent M113K very well in the mile race! Add your name to the list!
