I have one in my big engine. Once it went in, my clutch stopped holding. Definitely makes some power.

Got some parts in the mail from thedubshop.com today! New crank trigger setup for the mouse, hopefully the second half of the order will be here in the near future, I also ordered a Mini Cam Sync. This will be my second one, I'm excited to put it to use! Thanks Mario!

Been busy these last couple weeks. Finally ready to pull the big engine out and tear it down in prep for a quick re-seal and re-ring/cylinder refresh. I've been using the big engine as a jig for some updating. Trying to figure out how to make boost before 4000rpm without having to give up my overall ability to make decent horsepower. Here is what I came up with.
Image
This is a little TDO5-16G with Subaru flanges. I am planning to do a new header for the car next year, but before I commit to stainless, I wanted to test this sucker out first. It was pretty simple to build this quick adapter pipe that just bolts up to my existing T3 spot.

Image
I didn't want to deal with the inability to clock the turbo, so I took care of the internal wastegate as soon as the turbo showed up.

Image
Here is a quick view of the crank going into the mouse. Its a German 69 that has been counter weighted, wedgemated and nitrided. Should make for a pretty decent bottom end. I'm running CB H-Beams, as well as CB straight cut cam gears. I have a few more weeks before the new pistons show up. Plenty to get done in the mean time.

You must still be a young buck there Chip.......my garage floor would look the same way except in my elder years I have learned to make myself a small tool holder using a piece of flat plywood about 2.5' X 2.5' and setting it on a carpenters X stand.
I don't have to bend over every time to pick up tools.......although I also stack them on the tires, pan, buggy body, shelves and every other place convenient that I think I won't lose them......... :roll: :lol:

My floor is a joke right now. Needs a major cleaning. I really should just roll the tool box over where I'm working, then I might actually put something away.

Here is a photo of the exhaust of the little guy...

My local track is shutting down after this last season, and while the big turbo I've had makes driving the car a lot of fun, its not super practical below 4000rpm. At least the power isn't very comparable to the post 4000rpm power. I want to make the car more street friendly and I'm hoping that adding this smaller unit will help me wake these engines up much earlier than my bigger unit. While I like the idea of the potential for fast spool from the Subie turbo, I just couldn't get over the fact that it is about half the size of my big one, so with that in mind, I started looking into methods to get fast spool, and big power. I'm hoping this will help achieve that goal...

Image

Don't hate too much on the welding done on the muffler, that is old stuff from a much less skilled me from 4 years ago :roll:

This whole arrangement is a temporary deal. I'm hoping to prove out the concept over this current race season, and then once the snow flies, I'll make it permanent, with a brand new header, all stainless and packaged so I can hide it all under the decklid again. Should be fun!

So.... Compound? Don't they usually run the small turbo into the big one?

Compound, yes. Everything I've seen shows big turbo feeding the small one.

I'm excited to see this in action. I have thought about it myself!

Its kind of killing me not being able to test it right now. I still need to do all of the oil lines and such, but the car needs some help too. Engine needs to come out to address the clutch garbage, I still need to weld my clutch tube back into place, I think. I need to do some electronic rethinking for the boost control for each wastegate. Not sure if I want to talk to each one individually or control only one with the ecu and the other with a manual valve...lots to think about.

While that TD05 might seem a dinky turbo for you it is actually quite large especially for a 1600.
It is capable of up to 365 hp which means you will still have lag.
If I were you I would try it with just the TD05 turbo.
Your 2276 turbo is going to be overkill except maybe once you hit over 25 lbs boost.

I fully plan to go well past 25psi. I'm hoping to get around the lag issues on the 1641 with a little higher than typical compression ratio. I don't expect really great street manners with the mouse. I will definitely drive it, but accept that it is over-turbo'd, and has a big cam. This engine is being built to have fun with on the race track more than anything. The compound stuff will probably really shine on the big engine. Both will get their shot this season. Hopefully both setups will lay down solid numbers and then the car can retire from the strip for a little while.

This should explain compound systems to people who are interested (it did to me) http://www.motorsport-developments.co.u ... 7_tech.pdf

:D I've been plotting since just after Christmas. Finally started cutting steel a few weekends ago. Finished up the welding Friday afternoon.

That article is a good read for sure! I'm still learning a lot about this stuff too. I'm sure the curve will get steeper once fuel ignites for the first time.
