Is this a store bought seal or something someone has to make?

I have never done it Jim, it's obvious they are out there, as there are turboed 2 strokes and hydraulic seals that can take tons of pressure. I'm sure something can be made or adapted.

I personally feel that NOS, turbo or blowers are just "cheaters", and take away the skill of actually making hp through talent.

Really? Nitrous, maybe..since all you really do is "buy" extra horsepower and pour it in. But turbos and blowers are the ultimate ways to make big power..and the concept is brilliant: scavenge wasted power to generate massive amounts of air ... for your "air pump". Pound in a matching amount of fuel and hang on tight!

..bet you could find some gnarly old piston-port gurus who think reed valves are "cheaters".

If turbo's/SC's are cheaters, than so is an expansion chamber as their jobs are really not all that different... Cramming as much burnable mix through, or back into an engine.

While I prefer an NA engine, from terms of simplicity, a little engine with a big fat turbo is a riot... until it grenades. Then not so much.

We built a 400 small block street motor back in 1978 with a GMC 6-71 blower and dual carbs in a 66 Chevelle
Spent millions of hours with carbs, jetting, timing, camshafts, race fuel, big radiators, elec. fans, different head porting details, etc.
It was anything but easy; learned alot though.
The next motor was a conventional 350 with a roller cam, single carb, plenty of compression, aftermarket (but stock) heads
Basically a store bought motor that was more reliable and much faster
Same car now has a mild 468 that runs consistent 10:40's (tubbed) with NO maintenance other than rebuilding the turbo 350 and replacement of 12 bolt ring and pinion every 200 passes

IME modern blowers and turbos are the hardest to make consistent HP but can be extremely rewarding and reliable when done right
Pal with a GT Mustang has an an aftermarket blower that is quite the sleaper
Also love the torque that is often time lost with a radical normally aspirated motor.

I'd love to find someone that has done the R&D for a 2-stroke in regards to chambers, turbo, carbs, and seals
Price of turbos has come down
Do street bikes with turbos run a traditional oil cooling system like cars?

turbos and blowers aren't cheaters- they are power adders! I love it when I wax an 8 cylinder musclecar with my 6 cylinder vinyl topped Buick!!

You can't talk me out of it, they are cheaters in my book...... It takes no talent (other than being able to read and use a wrench) to double, triple or more a engines performance without even breaking into the motor.

Bottles are for babies, blowers are for hookers, and turbo's are for 18 wheelers!...........

Some would also say fixing a set of reeds to a piston port motor cheating as well I suppose...
To me all these things are just a way to make an air pump more efficient.

Speaking of efficient, that frame could probably use some diagonals to tie it together... Might be too early in the fab stage to judge that one though.

I don't know, John... without blowers you can't have K boats: http://www.youtube.com/watch?v=EIHmmsmucU0

Nice one Jim; not so sure the green boat didn't use a little "spray" the way he built a lead coming out of the far turn

One could say porting a head is basic machine work once the best flow dynamics are defined for a particular type of racing.
For Chevy's, some of the out of the box heads are as good as they get.

It's really about building and tuning a well thought out system for the application.
For many, the only advancements in the near term appear to be electronics design and implementation.
Unless Chris Ritchie dreams up some mad new part.
