Default Twin Turbo 928 fixed and back out there terrorizing the streets!

A new tuba duo will play its maiden concert sometime in May.

Expect something similar to this:



...except with slightly different brass wind instruments. These will still receive the Swain "makeup" before the big show:

John Kuhn's design, by the way, allows one to replace the burnt clutch without removing the exhaust.

Default New concert venue

I've got a new concert venue for the tuba duo on Wednesday. Three bays, so there should be some elbow room as well, as long as the daily drivers stay on the driveway.

It came attached to a house, so the wifey's not complaining...

Congrats on the new home, you've done well. Couldn't ask for a nicer garage! Heater and all, very lucky.

Looking forward to hearing the shark once you have it on the road.

You might want to paint the floor before you move a bunch of stuff in.

Thanks guys. I'll try to figure out how to get realistic audio of the car after it's all done. ETA four weeks.

[EDIT: It's been two months since I said four weeks. Right now, the expectation is 6/17 for firing it up the first time.]

JHowell37's suggestion about the floor is excellent. What I'd really like is very light gray epoxy coating on it. I am debating if this is something that I'll attempt DIY or whether to start to look for a professional.

Painting the floor with the epoxy is easy to do. From the pics, the floor looks pretty clean even though it's a few years old. I guess the previous owner didn't keep their car inside. If there are no grease stains, just sweep it real good, maybe rinse with a garden hose, let it dry completely, and roll the stuff on.

You could probably roll it on in about an hour.

Judging by the fumes that my curing epoxy floor gave off for more than a week, I'd save my brain cells and pay someone to do that job, especially for a gorgeous 3-holer space like that. The GarageJournal guys seem to think that if you want it done properly, there's a bunch of surface prep to do if the surface isn't brand-new virginal, either muriatic acid etching, or shot blasting, or both. There are about a thousand threads on epoxy, but here's a good one on surface prep:

Agreed, acid etching is a must to make sure the cement is properly prepped. There are also many types of epoxy available with different solids levels. Supposedly the higher the percentage of solids the better the epoxy. I'm going to paint mine next spring, maybe we can help each other and also share garage space while the garage is drying?

Can't wait to see the final results - you've put a huge amount of research into all your details. Looking forward to pics, impressions, and build specs!

The iteration zero version that will be ready in four weeks will basically be all John Kuhn's work. All I did was the fuel system up to the engine compartment. I have tried to help him on topics such finding the absolute largest turbochargers that fit in the physical space, offered opinions on breather system configs, etc. but he's had the decision making authority over all aspects of the iteration zero. I have to say that his system is extremely carefully thought out, has considered every single detail and its implications on the whole system. Go to youtube and view Herr Kuhn's clips there if you want to know more about it!

On other news, met with a coating contractor who quickly convinced me of the fact that although I could do the garage floor coating myself, he'll be able to do it better and at a reasonable enough price that I am better of not taking a day off from work to do it. That project starts tomorrow morning and the garage will be drivable Thursday night.

Some more photos of the tuba duo:

I hired a contractor, so at minimum I can give you an honest assessment of whether he's good or not after the job is done.
