Just had to share these pics of an older chevy v8 turbo setup.

I guess its like that to make it more plug and play???

before it was figured out how to make cards work in blow threw aplications.the draw threw method was the simplest way to do it

while it can be done this way simply,going blow threw or efi is a much much better way to go


to do a draw threw type setup it requires a turbo with s special seal on the compressor side , its been a while but i belive its a carbon seal not a dynamic seal thats used.


i actually have 2 draw threw turbos off 301 turbo engines iirc
i think the pair of them would be to small even for a stock 350

eventually when i have the spare time i want to build some diy turbines out of them

On a carb it's safe. Don't ever try that on EFI. If the hose between the TB and turbo/blower comes off, your WOT until key off.

I wouldn't be too afraid of the 301 turbos honestly. The stock engine made 200hp each so if you leaned on them I would think 500 would be not too much trouble. Would be sort of bad *** to pop someone's hood and see a pair of those on a dual quad intake or something and have a pair of air cleaners popped out of the hood. A set of adapter plates would make them mount up pretty easily to an intake I suspect.

Supposedly these can provide an advantage in charge cooling, if one were using E85 or the likes I'd definitely think this. They do have a down side however in the fact that you're bound to the CFM of the carbs. What I mean by this is on a blow through setup there have been people make 1200hp on a 650 CFM carb. With a draw through you have to have some serious CFM. Even the 3.8L draw through cars had the "big" Q-jet for instance, although I believe that you could get the 2bbl for some perverse reason early on.What's interesting to me is that there are 2 kits there, but they don't look like the Accel turbosonic or the Martin kit at all. Any idea on who made it?

Just woundering but woudn't the fuel "sand blast" the turbine over time? Im still sorta new so don't laugh too hard at my question.

yeah u could mount them up super easy but iirc the pair i have only has 42mm inducers they would work but a larger set would be much more efficiant.

i belive mine are stage 1 turbines with .84 housings and 42mm inducer coldside with an ar of .4x

would work really nice on a crossfire engine though

eventuallly the fuel would erode the wheels but it would take a long time

depends, the right (well wrong) conditions and you could wreck an impeller.

In this type of application it's not likely, but a turbo that was not designed for operation with product (wet, suck through) could have some issues due to poor material selection or other factors. At high RPM it does not take much to do damage, I repair the rotors/wheels/impellers for big industrial gas and steam turbines and have see some crazy damage from just a tiny bit of condensation happening at the wrong point in the turbine.

Wow, didn't realize they were that small. Even for the 301 being what it was that seems grossly under turboed. By bupming the compressor and adding some intake/exhaust I bet they coulda gotten a lot more power if the engine would hold up to it. On the other hand being a 301 that may be a challenge.

The other thing to consider is that fuel is liquid at room temperature and pressure. pulling some vacuum against the carb would likely help atomization as well preventing the issues at hand. Throw a bit of engine heat at it, and the droplets would likely get a lot smaller a lot quicker.

a custom skull head engine cover with a head leaning back with its mouth open where intake tubes go, and two skelton hands each holding a carb up like an offering to the speed deamons. Tubes off the turbo could twist or wind around and look like two snakes going into his mouth.

All the early turbo Buicks were wet turbo when carb'd, up to 1984 when they switched to mpfi. Those first "hot air" carb turbos were pretty cool!

The turbo was never listed as problematic so i don't see the harm in running it.

Drac0nic

the hot air efi cars use a tb at the inlet which means they should work for draw through too. may be easier to find too

as long as it has a carbon seal on the compressor side they will work.

most early turbos have carbon seals
and i belive the majority of the rotomaster and ray-jay turbos also have carbon seals

these seals are easy to identify by removing the compressor cover then the compressor wheel and finaly the compressor backplate

on the back side of the compressor backplate is were the seal sits its basically a big black piece of carbon that sits in a lil metal cup and its spring loaded.

just be carefull as these seals are very fragile and break/crack easy


and here is another one the carbon seal is number 3
