Yeah their website isn't the greatest. They mainly make turbo setups for snowmobiles But they recently got into the automotive market with the 53 and 65 series turbos. You can check out the twin aerocharged Pontiac G8 on youtube, and the porsche 911 kit.

Very interested to follow this thread. Looking at the technology makes me want to build up something to use one of these quite badly. Maybe the SR20det I've been thinking about for a while...

Derp, just looked at the design of the aerochargers, and see they don't use a wastegate. Interesting design...and very interested in your results. Keep the videos/pics coming.

Haha yup
I'll definitely do some data logs/photos/videos once the new fuel pump is in and i can turn it up to 12 psi. And of course some dyno numbers.

GtiKyle where are you located?

Ah okay gotcha


Installed the new fuel pump and rubber shift boots.
Drove through a parking garage yesterday. Nothing crazy. If you wanted to hear it here you go:

You should fill out your profile so that things like location etc are easily ascertained. Where are you?

Ah true, thanks for pointing that out. Thought I had already for some reason.

I'm over in Pullman Wa, pretty much the middle of no where. Some more Miatas would be nice, once all the students leave for the summer the only vehicles in town are trucks and that one dude who rides his horse to Walmart/Safeway.

Not yet, I've been slammed with finishing finals and moving. One of the hood latch bolts worked its way out and the hood opened up on the highway at 60, so definitely need a new one.

I also resurfaced the exhaust manifold and turbo since there was a small exhaust leak.

But I'll get it on the dyno very soon, it's just about ready!

I think tech is probably cleaning off his keyboard after trolling this thread from the depths of ban land.

This is actually really cool. I def don't have the ***** to deal with a product like this. I'll take a chance on something new and cool but this turbo is a bit out of my comfort zone. Subbed.

I'm keeping a very close eye on this thread. I have a lot of interest in a track car with one of these at some point.

Very interesting alternative.

Can you explain how you set boost levels on this thing?

Thanks guys, I appreciate the input!

I'll explain how to control the boost on this thing.

The boost controller regulates maximum pressure, and boost response.
If you look at the photos from earlier of the turbo there's a vacuum line that runs from the compressor outlet to the boost controller. The boost controller works by a simple spring and diaphragm system to move a push rod, which adjusts the vanes on the hot side. By using different spring tensions and washers (as shims to fine tune) you can change the maximum pressure that the turbo produces by controlling how soon the vanes are pushed completely open. The barb fitting on the boost controller also acts as an adjustment **** for boost response, if you want a slower response you can tighten the fitting into the boost controller housing, pre compressing the spring, making boost buid more gradually.

Right no I am running a 10 lb spring with a couple washers to adjust for pressure loss across the intercooler and tubing.

Hopefully I covered most of it, let me know if something doesn't make sense.

Super keen to see how this thing goes and how long it lasts!

Good job man!

Thanks for explaining. And does it compensate for temperature changes like an EBC would, or do you have make adjustments as the ambient temp changes?
