Can you put a throttle body on a carb intake?
No. Not the way you’ve written your question anyway – you’re implying that you have a single carburetor, and you want multiple throttle bodies. That’s not how they work.
Can you put a carb on a TBI intake?
Basic Hardware. The most basic things you’ll need to convert from TBI to a carburetor is a carb and a matching manifold. You could try to track down a used stock manifold, but aftermarket aluminum manifolds like the Performer RPM make more power, are lighter and will only run you about $60.
What’s better TBI or carb?
So most TBI systems can tolerate radical cams with durations up to about 250° with much more finesse than a carburetor. The engine will run smoother, idle better, start easier and provide better throttle response and cold driveability with TBI than a carburetor.
Can you cam a TBI 350?
This cam is designed specifically for the TBI 350 small-block and specs at 194/214 degrees of duration at 0.050-inch tappet lift with 0.398/0.442-inch lift. The downside to this cam is that for a tow vehicle, it may hurt the low-speed torque slightly, which might not be a bad thing.
How do I switch from carb to EFI?
How to Complete a Carb-to-EFI Fuel Injection Conversion
- Tools and Materials.
- Remove the Carburetor. Take off the fuel lines and hoses that come from the carburetor.
- Install the Injectors in the Intake Manifold.
- Install the Throttle Body.
- Install the Sensors.
- Adjust the Distributer.
- Set up the Electronics.
Is TBI better than a carburetor?
Even so, a TBI system will start, idle, run and respond much better than a carburetor, and will maintain a near perfect tune over a much broader range of temperatures and operating conditions.
Can you convert a fuel injected engine to carburetor?
Originally Answered: Can a fuel-injection system on a car be replaced with a carburetor system? Yes, it can. This is actually fairly common with General Motors V8 engines in custom cars.
Which is better carburetor or EFI?
Warren Johnson: Properly tuned, carburetors make more peak power than EFI in a Pro Stock engine. EFI performs well over 2,000 rpm or more. On average, if optimized, both systems perform about the same as far as how fast you get down the track. However, the EFI system is much easier to tune than a carburetor.
Why do I have so many vacuum lines coming off the intake?
So why do I have so many vacuum lines coming off the intake manifold? Well, this is because that is where the vacuum is present. Since the intake manifold represents the area behind the throttle plate, the highest vacuum that the motor produces will be found in the intake manifold.
How does the throttle body work on an engine?
On older carbureted engines, the throttle body is built into the carburetor and via mechanical means and engine vacuum, more fuel is delivered as the valve opens.
Why is there so much vacuum coming out of my throttle?
Take that same situation when the throttle plate is closed and the motor will be generating a lot of vacuum as it struggles to suck as hard as it can to pull in air and feed itself passed the closed throttle plate. One thing important to understand then, is that vacuum will only be present BEHIND that throttle butterfly.
How do you tell if a carburetor is vacuum or mechanical?
On a mechanical secondary carburetor, like this Ultra XP 4150 (left), there is an additional pump nozzle over the secondary throttle plates. The vacuum diaphragm housing, like the one on the side of this Street Warrior carburetor, is the giveaway for a vacuum secondary carburetor.
