Turbo's
Not heard anyone mention getting power via a turbo set up - like the Chevy one thats on Ebay for the next 6 hours - wants $1200 for a quick sale.
Anyone out there running a turbo or maybe twin turbos ????
If so - tell us all - would be VERRRYYYYYYYYY interested to hear all about it.

it's at 510 now

It looks like a pair of truck headers with a flange welded on them. Where would the turbo's mount?high or low? if it's low, in front of the engine you will hit the control arms if it's up high you will need a taller hood. Looking at the headers it looks like they mount down low (with the header flange the proper way around)
Also, this kit is only 2 headers, 2 turbos a carb hood and some misc. parts, you will need oil pressure lines, waste gates, preferrably intercoolers, down pipes, piping to connect the components, a boost retard system, a boost referenced fuel pressure regulator...and so on and so on. For 510$ it may be a nice starter kit to add the encessary components on.

That's a martin system, similar to accell turbosonic. It uses a special manifold with internal butterflies to redirect the charge under boost/non boost circumstances. It's pretty nice for a vintage buildup but it can NOT be intercooled (because it's a draw through setup) I don't see the crossover tube for the exhaust in the pic, is it not included (one side uses a normal ram horn, a pipe runs under the engine and connects to the other side so both banks drive the turbo)
Looks like it's a pretty complete setup otherwide, even though buying used turbochargers is always a risk.
If you want to build something different and have the $$$ go for it. Do not however expect to make gobs and gobs of horsepower with that.
I've always liked the martin setup, it looks cool and has a vintage look to it. One day I may get one (if the price is right) just to play around with.
I have a pic somewhere of an engine sporting that setup, looks real good.

There can be problems with the "boost flap" in the Martin set-up sealing properly when the system gets into boost mode. I worked on a 1978 L82 Vette with this set-up in about 1982, we had some fuel distribution problems with the H.P. engine. The Martin system was O.K. but, I would go with a centrifical supercharger if I was doing a carburated blown through system. The fuel curve on a blower is easier to "dail-in" than a turbo because of the more linear progression of boost in the supercharger. My 2 cents (and lots of skinned knucles and head scratching over the years.) The ultimate power is going to be a EFI fueled turbo but, superchargers have their place too.

TT, where the hell do you come up with this stuff??? my god, that looks like a mess. anybody wanna help adjust the rockers? (hehe) i just can't see using a turbo on a carburated application, largely for reasons mentioned here. max boost you could run would be, what? 3-5psi? after you figure the added charge heat, you'd be better off just building a high compression N/A engine.
hey TT, just food for though. if you weren't going to worry about intake charge heat, what would you think of something like a L98 or LT1 plenum with a turbo bolted straight to it pulling through a side draft? probably not very effective but if you just wanted to build something nobody else has, that might be kind of neat.

a mess? it's much cleaner than mine, at least this setup allows you to adjust 1 bank 
, I have to tear everything apart to get to the rockers The carb is not what limits max boost, the lack of intercooling does. It however is easily dismantled, not that much of a problem and how often do you adjust hydraulic lifters?
As for your idea, why not blow through a side draft? 1 would be too small though, I have 4 side drafts and they are blow through, then again they are specialy pressure tight carbs (up to over 40psi) with an extra jet for under boost, off a lotus esprit turbo..but they are damn hard to find.

TT, i thought yours was FI. haven't seen that cool pic in a while. do you have any other pics that show the side and/or top view? i thought your turbos were mounted on the side with only routing going over the covers. in the pic you posted, it looks like the whole turbo would have to come off to adjust.
understood about intake heat, hence my reference to intake charge heat.
actually, my idea was to draw through. wouldn't be very effective (all the fuel would sling to the outside) but it would look cool. picture this: say two independent manifolds, like the current c5r uses. mounted directly to each intake of the manifolds is the output of a turbo then mounted to the intake of the turbo is a two barrel side draft. it would look really
performance would suck and you'd probably wash away the rings but it would look cool!
