has any one tryed to do this

i got a cupple of turbos laying around
from diffrent cars

if i mount the turbo on the headder on one side

and then ran a ducting to the top of my carb will this work



? can the turbo only be on one side of the exost or
does it half to be on both sides


what does a waste gate do

Uh, ok I'll bite. How can you have a couple of turbos laying around, and not know anything about them? :eek:

Seriously,

There is more to the turbo game than just "duct work". I would NOT:

use a turbo and a carb.

use a single turbo on one bank of the engine.

put a turboed 350 in a buggy.

I'll probably catch sh!t for that last comment, but wtf. Turbos need time to spin up, unless you are using sequential multi-diameter ceramic units, with a specialized injection profile. Most sbc's that I have seen turboed have had razor sharp power bands, which is something I would think that you would want to avoid if you really have a "95 rockbuggy".

Superchargers are a completely different story.

Oh, and a wastegate "pops off" excess boost or "pressure" so that you don't blow the heads off your motor.

Most turbocharged engines that use carbs are a draw through style..If I were doing it I would I would copy the Buick V6 turbo from the early 80's..

there was a twin turbo set up on ebay awhile back. They have been turboing small and big blocks in the boat industry for years. It is very possible. I would talk to the right people. though.

Look at this group: groups.yahoo.com/jyturbo
the jy is for junkyard. A really great bunch of down to earth guys . They will be able to tell you how to identify your turbos, show flow charts, etc etc.

International did it with a carb

cant be to hard to do

You know, This is a very common misconception... Turbo's don't necessarily have to have a lot of boost lag... it comes from people running large turbo's on small engines... If you have say a 2.0 liter turbocharged 4 cyl engine pumping out over 500 horse... off boost... it is just a low compression 2 liter 4 cyl... so you get a really weird torque curve where the car is gutless for a while, then gets crazy amount of power. This doesn't have to happen when you are running a large engine like a 350 ci V8... Even a lot of turbo'd performance V8's will reach full boost by 2500-3000 RPM's... By simply sizing a single turbo for the job, you could easily get a turbo that will reach full boost very quickly with almost no perceptable lag. A friend and I put together a twin turbo setup on a small block in his car, and let me tell you.. there is NO boost lag in his car, and the engine (an L98) has a SICK amount of torque. A turbo will give a much stronger torque curve than a centrifugal supercharger.

In my best Billy Madison voice

JUST DO IT

You want to run the turbo off the collector after both manifolds or put 1 smaller turbo on each manifold.

You can't just use any old turbo though you need to either use 2 say Garret T25s (They were on 2.0L engines 2.0+2.0 =4.0 you have 5.7 so they should spool up quicker but eat into your top end, heck they may be boosting at idle.) or a big ass turbo but I don't know of one off hand big enough.

Either way IMHO putting a turbo on a carbed engine isn't going to be reliable, look for a MPI swap then boost it.

Then put one of these on it when ur done http://quicktimeperformance.com/qtec.htm

I have to call Bullshit on this! There are plenty of boosted carbed engines out there to prove you guys wrong. The best bet seems to be a blow thru setup with a 390'ish cfm carb. The trick is not overcarborating. With a little tuning these can really kick ass! If you are afraid to tune a car, then go for the injection.

The only boosted car I currently have is a little 2.2l with the IH RHB5 turbo. It spools at around 2200 rpms and makes about 9-10lbs right now. It makes a lot of difference, but I agree, it might be too twitchy for wheeling. The boost hits pretty quick, and the second you let off the throttle, the boost is gone and it takes a bit to get it back. In your application, a supercharger would be far better. The make boost in a much more managable form.

use a turbo out of a 6.5l turbodiesel. I've read about guys having used them on 350's with very good results. The turbo needs to be hooked up to both exhaust sides though.

I think the guys were trying to help this guy who OBVIOUSLY doesn't posess the knowledge to do his own turbo job if he doesn't even know what a waste gate is. I just don't want him to trash his motor because we said "just do it, it should be fine." He is going to come back on here and tell us about how half his motor seized up because he leaned out his mixture to much.

Dude, do some reading and research. Take what you read on here with a grain of salt. Remember that ANYTHING can be done. I have read about a motor that had 8 turbos and 8 weber carbs that made 3000 horses. And that was at 1K rpms. I have also read about a motor that weighted 50 pounds had 32 cylinders and made 600 ft-lbs of torque at 300 rpm called the PowerRing.

Everything can be done. So go and blow some stuff up after you do the leg work and know what to expect.

Here is a turbo setup in a (really ugly) Dodge truck with a 360. The principles are the same. The turbo is a T-4 that's being kept to 10lbs of boost. We aren't sure what RPMs the turbo spools because we are too busy hanging on (no shit)! The motor already had sack, but this is just rediculous! :D

This is kinda cool.Twin turbo (http://www.truckworld.com/4x4-OffRoad/96-1957TurboWillys/1957TurboWillys.html) ,propane powered 350.

Erich,

It looks like there is an intercooler on that Doodge? Do you know what type, how much boost?

Marc

It's a T-4 turbocharger running at 10lbs. I don't know what the intercooler is off of. He usually gets the intercoolers out of junkyards or Ebay.
