use 308 filler on stainless to stainless.

I have both 309/308 and misread the Lincoln site for 304 to 304

This is how I did my pre-turbo water injection.

I took the S-bend out of my intake. That was good for 14 more hp.

Diy square top. Love it.

Is the pre turbo WI an Aero profile?

wait wait wait... what is the benefit to pre-turbo meth? Doesnt that eat up the turbo?

Wet compression is wicked efficient for charge cooling. It can erode the compressor wheel, but we're not talking about chewing up a compressor wheel a week. We're talking a little visible surface finish damage over the life of the turbo.

Just don't use water if you have an efficient intercooler. If you are using a really effective intercooler or it's really cool out it can condense back to a liquid and pool inside it.

well I was looking at injection for my poopra, and the way my intake charge piping is, is 1980's retarded by leaving the turbo, down into the intercooler, then back up the hot side, and over the motor into the intake and i am not ready to buy a front-facing intake manifold; nor do I want to go through the effort of making a injection system for the charge piping before the throttle body, or intake manifold if im just going to swap it out in the future.

This might be my best option for water injection. Would it be safe to mix a 60/40 water/meth mix, or any methanol for pre-turbo injection, or is meth most beneficial for intake manifold direct injection?

In my case the intercooler is an older FM one, probably not the greatest. A lot of guys run pre-turbo on their rotaries with good long term results. I don't remember the nozzle size, but I'm sure it's conservitave. Current theory says that if you have enough injector you run little to none of the meth/alcohol as the water is the prime reactor for removing the heat from the air.

If/when I switch to flex-fuel I assume this would no longer be necessary. Somebody else chime in on if this true or not.

For a different kind of fabrication I wish I could share some of the images from the lab I am in. We work in nanoscale physics research so get to do a different type of fabrication. For instance in one of the projects we are measuring signals from a .7 nm thick layer, which for comparison the size of an atom is around .1 nm or so.

I can probably share this crappy image I took with a damaged SEM. The bright spots are a 2 nm thick of platinum. Usually we try to make as uniform layers as possible but I was testing something where a lot of pinholes in the layer was desired.

Angstroms good sir and fix your stigmation. What lab do you work in?

I am in the Krivorotov group at UCI. Someone from another group had crashed their sample into the pole piece and it hadn't been repaired yet so this was the best I could do. SEM time is difficult to get (notice the timestamp) so unless the image is going to be published I just get it good enough. Also there apparently was some issues with the immersion mode that was finally fixed today. The joys of shared user equipment...

Sounds like you have experience with this. From where?

I was an engineer in a nano fab facility for the last few years. Mainly doing chemical engineering.

I spent a lot of time on an fesem. Looks like you guys are working on some interesting stuff.

Which building do you work in? Are you a TA (I thought most PhD candidates were)? I majored in Biosci at UCI - three quarters of physics and labs were required. Seemed like a lot of those premed kids were speed junkies at that school to try and stay competitive - ever notice that? lol.

There was so much funding and new buildings after Rowland and Reines won the Nobel prize. Good times. I love that school.

I am in the basement of Reines Hall. Kind of an interesting place. The neighbors next door have a setup for liquifying Helium and further down the hallway is the machine shop followed by a nuclear reactor.

Luckily I only had to TA for a year here. I heard the premed here where awful but I had the engineering courses and was busy yelling at them for not being able to do simple calculus. When I did my masters at CSULB, I had premed in the classes I TAd. Constantly got told that they needed an A on whatever BS they turned in and usually replied pretty much with "cool story." I had someone with less than 10% expect to pass once and get super pissed at me. Also got yelled at for failing most of my class (and forced to raise the grades up) that was unable to calculate slope of a line or perform any form of basic math... even though they are in college and math was a prereq...

Me.. A in college Trig, D in Calc... wtf was I thinking taking that god-awful course during the summer?!
All I needed to know was how to make dilutions and calculate concentrations. Degree was in Microbio which basically turned to Mol Bio...
Now I make 4x as much as I did then fixing lab ****... true story bro.

Back on topic... pics of awesomeness?

Fe3 miata turbo custom intake manifold.

Just need to add throttle body flange, vac ports and throttle body cable provision.
