Has the draw through turbo buick setup ever been used before

Wondering if anyone has had success with using the early carburated draw through turbo setup from a buick?
 
I dont see why it would not work, you just need to figure out how to rig fuel lines and throttle linkage.

With a draw through setup you also wont need any carb mods other than to rejet one or two more on primary side and bump two or three more on secondaries.

You can get a MSD module that can retard spark as boost goes up.

The draw through turbos use different seals and bearings than a blow through carb. IIRC it has to do with gasoline getting into bearings and seals.

IIRC the Buick setup uses a box that sits on intake side, I haev seen them on the net, you can probably track one down.
 
i believe it's been talked about, and theoretically built, but i don't know if anyone went from theory to actual build

Seems like if you could find the right sized CFI unit you could Fuel inject system instead of a carb.

I know the turbo blades would love the smaller droplet pattern of the injector spray. Draw through turbo users have commented on wear on the turbine blades when the fuel hits them.

Pardon my ignorance, but if you're going CFI, why not just blow through it?

yes i have that same setup on my car it works great i just made an adapter to bolt it to the intake.
Got any pics?
 
sorry i don't have a digital i will see if i can barrow one and get back to you asap. i don't get on this site much or i would have gotten back to you sooner.

I agree with you 100%. Blow through would allow you to run a intercooler and most blow through systems have reduced turbo lag but alot of the turbo lag can be reduced by a properly setup system.

But if hes got all the parts already for a draw through system that can be made to work too.
