You should seriously consider running E85.
Your safety margin goes from |__| to |______________________lel______________________|

 

lol, I'd only be able to fill up in Ashburn, Alexadria and Bethesda. Maybe I just shouln't run all the boosts. Maybe some Water injection as a bandaid.

Maybe go NA

 

Ungh, E85. So many wants

 

Eek. That's the weak point of Supertechs.

 

Well good thing these were Wiseco!

Actually, while we're on the topic of Supertechs...they are coated right? Every picture I see of them online show them to be flat grey.

This is what I got in the mail today:

Supertech
8.6:1
84mm





Kinda shinier than I expected.... is this right?

 

Oh OK so they have similar designs.

 

Were your pistons this shiny?

 

My Supertechs look like your Supertechs, looks more like anodized than a coating. It depends on the camera and the lighting?

Edit: Pics!






I can get that same color change depending on what angle I hold the camera in relation to the lights. Seems to do this more under florescent source. The pocket on the underside in the last pic and the face of the bottom edge of the skirt is what my eyes see, rather than what the camera sees. Hard to explain. But you are right, definitely not the dull matte "coating" I was expecting based on other peoples pics.

 

Even though we did as detailed of a job building the motor and I think I have a good tune, this kind of stuff worries me. Is it just me or do more people have problems with Wiseco pistons than Supertechs? I have Wisecos in mine now and running 17psi with the same turbo.

 

Don't worry unless there's a reason to worry. Lots of people have had successes, it's the failures that are easy to remember.

This is just a reminder that nothing is forever. I hope to be even more careful the next time around. Maybe not get too drunk on boost and keep it a bit more conservative. I'd like to add knock sensing to ms3 though...


Also with regards to piston brands, any piston can fail if the tune is spotty. If I recall, Savington or another one of the knowledgeable members had a dented dome on a Supertech. Others have had hot spots on the valve reliefs if it weren't hand finished.

 

Thanks for your words of encouragement. I was tuned by a former FM employee and recommended tuner so I am sleeping OK at night, but how much power were you putting down and what boost levels? Our builds are nearly identical. I made 311/285 on 17psi

I was under the assumption most MS units had knock sensing. My guy had to set the parameters for the knock sensor because he said it was going off way too often and that with my forged internals, the noise level is higher so the sensor has to be set differently. Once he was done that he was able to start tuning. I have an MS2X

 

This is why I want to run water/meth. I have no access to E85 so options are limited besides being conservative on my spark map.

That is some gnarly damage Psyber...sorry friend.

 

The knock module is extra and has to be added to the daughter board on my ms3. For $85, it'd be a great tool to help mitigate or at least inform the user of damage habits.

Thanks for the words. We break, we rebuild, then we spank her naughty.

We never lose (though it might feel like it sometimes). We either win, or we learn.

...and then lose some money in between. Ok yes, we lose.

 

The Enhanced MS2 that Alex has already has advanced knock control on it, using the same chip as the MS3.

 

So should I take this opportunity to upgrade or change my intercooler for fear of having miscellaneous shavings from the compressor housing?

If I recall, the begi and precision intercooler have the best core design with a higher fin density. Not sure if I' sold on the vibrant cores yet.

Anyone care to weigh in? Should I just keep my Begi#3?

 

My vibrant fab9 core kept temps good on the dyno and street. Not idea about track though.

 

I too have a questionable IC on hand (junk yard/dirty unit).
This might be a terrible idea but this is my plan to clean it out.

1. Rinse it with yet to be determined non-hazmat aluminum cleaner.
2. Hook one end up to turbo.
3. Hook up other end to a pipe that points away from my car.
4. Take it to the rev limiter.
5. Refill with cleaner, swap intercooler hookup (blast from the other side).
6. Repeat until I feel good about it.
7. Run it until the IC is dry inside.
.....Maybe go easy with the throttle to make sure impeller speeds don't get out of hand.

 

Or use a leaf blower ??

 

Hmmmm all pine trees around me. The OP however lives in VA so a leaf blower is certainly something that could be near by.

Not nearly as cool though

 

Just rent a pressure washer. On mine I can inject soap into the lower pressure attachment. Makes cleaning things easy.
