No,i think it's cool, but it took you a mile to do it...:rofl: Lets see what you got in a 1/4 mile???

does it irk you that i've done what it took "others" Several hundred passes and several hundred thousands of dollars to do? On a shoe string budget...

With no failures!

Whoa there buddy, now i usually dont get into these pissing matches much, but I gotta take issue with this whole "shoestring budget" statement. How exactly do you justify that? not counting your asskissing for freebies time there? what if you counted all of the cost of the parts that you got by camping under legitimate buisiness owners desks? That statement right there is bull, and you and everyone else knows it. you think that your shit smells cleaner than most, well im here to tell you that it smells worse than anyone elses in this thread...trust me i know another person just like you here locally. do you even do your own tuning? last i hear that was a big fat NO. you really should stop spouting off all of this bologna because none of us are impressed with what people can build for you and you can claim as your own....

rant off. :angel:

Well its obvious that you dont care what really works...


So i'll just leave this tiny bit of info for you to chew on

50 passes, no engine issues
5500+RPM
1200+HP
No girdle
Stock crank
Stock main caps
No piston problems
No crank problems
No block problems...and we aint even turned it up yet!!!


HP is HP no matter how you make it!

Must be on to something...;)

so 50 passes at 6 sec/4000lbs, im not a math major but thats maybe 15 passes in a 8000lbs pull truck? wow thats something to be proud of! know pullers that make more passes then that on a dyno before the season even starts.. gez hope it makes it to the first pull
i am nobody in the drag racing or sled pulling world, i havent been around very long and know nothing about anything but your duramax god attitude and posts are about the most annoying thing ever, i bet your mommy and daddy are proud of your efforts on your sponsered velcro shoe string budget. :thumb:

It's all speculation at this point. I hope it works, they sound like a great alternative for a daily driver as long as the harmonics are not a problem. Right now you have to use cast for a daily driver and they are still known to crack.

Don't be scared of change. If it works out, the competition dmax just got even better!!

Behind every sucessful person there is a line of haters.....Get in line.
No comment...although I had a funny joke that I'll leave out for now.


Steel pistons are a bandaid....
OK, I'll bite, we all know that they will help with the piston erosion and with the Keystone ring should be more durable than the current batch of Forged pistons without a Keystone ring land, AND since they are more weight will OBVIOUSLY put MORE stress on the crank (which is a "suspect" part to begin with and Physics dictates it will cause a % increase in the amount of broken cranks), but these facts are known by the masses, what can you add to enlighten all us "idiots" about these pistons?

but what would i know...
You know how to come off like an ass on the internet, how to take credit where it's not due, and yes you do know how to make a light vehicle with aluminum rods go fast and last a while (but many have done that BEFORE you, just because you have done it with a Duramax is not a big deal).

Edit: Hell, I'm a nobody and I've worked on aluminum rodded, forced induction engines, pushing out over 2000HP and full throttle for close to 30 seconds at a time.

Apparently nothing by your own admission.

  • You've got 50 passes. Many guys in here didn't see cracks/melts until hundreds of passes.
  • You've never run a real Dmax truck, ie heavy.
  • You've never run steel pistons.
  • You've never towed heavy with your car.
  • You've never sled pulled with your car.
  • You've never run fuel only.
  • You've never ran WOT for more than 10 seconds.
  • You've never ran big boost.

Your "solution" to every Dmax problem is to run tube chassis, track-only, single-purpose. Sorry Wade, that isn't a solution. 99.9+% of Dmax hotrodders aren't going that route. Nor are you a freaking rocket scientist either. If I was going to run a tube chassis car, I'd run a rail chassis. Safer, cheaper, faster, lighter. You didn't even do YOUR solution correctly yourself.

This is why I'm kicking dirt on your shoes in this thread, and I'd guess why others are too. You know NOTHING about this topic or problem. Nothing. Not a damn. Zippo. Nadda. But you have the "answer".

Now here's the punchline: You might be right. Steel pistons might not be a workable solution for the problem. But it's like you claiming you know who will win the 2012 National Spelling Bee because you own a dictionary (yet don't use it). However it's worse than that. Based on your past history, what you're trying to do is sell "your solution" via free advertising. You are perhaps hoping someone PM's you for more info so you can sell stuff. You lost your selling priviledges at this site, so go sell elsewhere if that's your plan.

For those who don't know, Wade was welcomed with open arms at this site, and allowed free vendor status. This was BEFORE he had a running Dmax of any kind. A number of folk on this board gave Wade tons of free advice when he asked them in private; I was one. It was his actions that got Wade on the everyone's shit list before he started racing his car. He keeps claiming he will grow up and fly straight, but it's not happening.

So bully for you Wade, run anything you like in your car. But stop boring us with your useless drivel in matters you are woefully inexperienced with. Even on subjects you DO have some knowledge in, you aren't different than a Timeshare Condo salesman, so the info can't be trusted.

And yes, Tony posted Dyno. Your turn.

Back on topic:

What are the list of Cons on these:
Price (depending on how you look at it)
Weight (how much more do these way than the average stocker)
Any others?


Also depending on "use", I'm assuming there were comprimises made between material, weight, and strength. ASSuming these were made to be the ultimate in strength for MAX effort, could these be machined furthur to reduce weight, knowing power output on a particular build was going to be limited?

X2!! Please epxress opinions about the pro's/cons! aside from the obvious weight differential. I too would like to know what would the difference in weight be from cast to steel.

I would think that machining them (anywhere but the combustion surface)would reduce their structural intregity.

but I am no genious by any stretch of the imagination.

This type pistons have been in use on big rigs that go over a million miles so durability shouldn't be a problem. Yea some or these produce over 500 ho and tonss of torque. Weight won't be as much of an issue and some might be thinking.

Price? I'd like to know that myself. Steel will probably be more money since the machining time is higher, and they are using billet (based on DPmag blurb).

Weight isn't as low as possible if they are billet. There are limits as to what you can machine out of billet. Investment casting would be lighter. But is weight going to be a problem? I honestly don't know. Higher weight WILL reduce bearing life, put more stress on crank, pin, rods, and reduce HP. The question is how much? A computer simulation could generate what the stresses are. Due to physics, this problem gets worse geometrically as piston speed climbs. Velocity squares the load, it's not linear. Twice the RPM makes 4 times the load.

Mahle certainly has the resources to do the math, but the question is whether Mahle will release any info.

Steel doesn't expand nearly as much, so you can run tighter bores, which can improve engine life. Ring and ring land issues will probably not be a problem any longer, nor will there be aluminum oxide deposits to stick valves open.

About crank breakage? Well, our OEM cranks break at 250rwhp and they survive at 1000+ rwhp. I'm still of the belief that this is a factory mfg process variation that is causing it. ie - Something happens during mfr'g that makes a "weak" crank now and then. If that's the case, we actually need a way to spot the bad ones before install. Mag particle inspection might not be enough. It's probably time to start X-Raying these if possible, and do some hardness testing. We can't get the original coupons that come with the metal batches, so we are limited on strength testing.

Or get a forged alloy steel aftermarket crank. You aren't likely to break a well engineered forged crank at our power levels.

Steel pistons are a bandaid....but what would i know...

running any motor over stock power with aftermarket parts is a bandaid. if it was never designed for it, your just bandaiding the issues normally caused by the higher power to achieve your goals. Unless you engineer a motor from the ground up, your motor is just as bandaided as all of ours wade. :thumb:

What sucks is I had the contact info and had spoken with one of the Mahle engineers a few years ago. I can't find it anymore. It would be nice to get some info from the horse's mouth.
