With a good tune I can't see why they would last any shorter/longer than an OEM headgasket. Of course the reality is they are usually installed in cars that are pushed to the limit and often beyond it.
I'm not going to jump into the obvious debate here because everyone knows where I stand with it. I just wanted to throw out there that most people I've seen with the magical spongecake aren't pushing their motors at all...they're doing it "for safety and longevity" because they cheap out on the other components of their turbo system. Perfect example...couple months ago when I retuned by a local tuner their was a guy on the dyno before me with a Greddy kit, meth, and a 3mm HG. After fighting with the god awful Emanage Ult software, he drove off with a earth shattering ~300whp @ 15psi. I get strapped down and do a base pull @ 10psi with the AFR under the 10's up top and pulled 310whp. When I asked him why he did the 3mm HG and meth, he said 'so the motor lasts'.
Yes, there are a few in the 500's on 93 with the HG installed but when the stock motor makes 400+ with 93, I really don't see the point in going through all that trouble.

There is way more then a few 500HP guys on 3mm, same as stock CR
I guess time will tell w/ my set-up........
If the weakest link in my set-up is the headgasket I would prefer that to go instead of some other component of my engine taking the abuse. I have a relatively safe tune, 3mm HeadGasket and 500cc/min worth of a 70/30 mix of Meth/Water. I am Boost happy so I do get on the car, I am easy on the tranny, not so much on the motor. I am at 1,300 miles since my tune on the 23rd of April and so far so good
now, hopefully I can say the same thing 20,000 miles from now.
also the guy with the Greddy kit, the headgasket wasn't his issue, it was his Turbo........(as I am sure you know)
PS. Also I don't think your suggesting that guys that do the Headgasket "cheap out" on other components of a set-up, kind of came off that way. I think I was pretty thorough, from Supertech Valves to Brand New OEM AP2 springs & retainers etc...........new Series 2 with great knock detection/protection, Water/Methanol to add some safety, not strictly for squeezing out every last HP.
It's all in the tune and if your tuner suggest a 3mm Headgasket, thats what you do, if they have experience in pushing 20+psi on the stock motor, then do it, different strokes for different folks.
I am not saying I won't be disappointed if my headgasket blows, but I am pretty comfortable with it, a safe tune, and 19psi with Meth
Rant over

As far as I'm concerned, I would NEVER hit 500+ on PUMP gas with the stock CR...ain't gonna' happen.
This is why I decided to get the 3mm head gasket. I'm not willing to pay 10-15 bucks a gallon for race gas when I can just lay out 300 bucks and get the same power and safety net.

5 gallon jug of M1 30 bucks
5 gallons of distilled water 5 bucks
for 35 bucks you have 10 gallons of 50/50 mixed meth/wter 3.50 a gallon. add in the fact that it only sprays when your above the boost you set it at and it lasts a decent time.
siadam showed what could be done on a bone stock motor with pump + meth/water.
if you only feel comfy with the 3mm HG, then do it. me, i am gonna push the stock motor until it fails, then go laskey built block.
although, the mahle pistons are starting to strike my fancy. i read that you can drop them in without a rehone if your walls are good. thats very promising. god i wish the walls were normal, then none of this special piston crap would be needed.

However never say never.
5 yrs ago everyone would say you would NEVER be able to make this much power on a stock 11.1 motor, IMPOSSIBLE, CAN'T be done.

while i dont understand your reason for not going for 500 on pump, i will say there are other ways to richen up the mixture besides 10-15 a gallon race gas.

In the long run (yes I did the math), I save tons of money by keeping with the headgasket and it's just as safe.

The key word is "I" would never hit 500 on pump gas, I have a log turbo kit. I would need race gas or meth injection.
