How does it work?

[Gaz64]

A carburettor can make more power because the fuel IS vaporised by the time it gets in the cylinder. The whole tract is full of vaporised fuel.
Have a look at individual runner outboard mounted injectors like V8 Supercar, F1, etc. The big horsepower cars run their injectors outside the trumpet.
Fuel ecomony is obviously worse with a carburettor because of wasted fuel going out the exhaust at valve overlap.

The difference may only be 10hp which would not be worth the loss of driveability, cold start performance, fuel ecomony etc compared to OEM port EFI.

I'm been reading a lot this weekend due to the heavy raining over here .

I am a torque guy,hp is nothing whiteout torque.( my opinion)
The car is strictly for street driving so those high rpm hp's aren't useful .
And verry expensive!!!!!( raced with bikes so I know)

As I understand it correctly,
I can mount an other intake manifold just for the air intake( intake has a hole for the maf sensor),and mount an wicked k&n filter on top.
The one I found was a edelbrock victor jr,I don't know about the rpm range.
It was from 2500-6200 I guess.

I know i have to buy an other gas pedal.
Do I then work with the stock gm wire harness and computer?

Or do I have to go to an other compagnie who make there own,and there own
Computer ?

I don't seem to find any pictures of the exhaust sensor mounting on the sidepipes?
The best thing would be to make a 4-1-4 on each side with a mounting hole in the middle I think?(correct me if I'm wrong).

I think some more reading is nessacery

Look at these pages:

These are just an example. You have the EFI intake, throttle body, and ECU. You could also use a FAST ecu computer system which would probably be easier to adapt to the throttle body.

You can also go this route which uses a traditional intake manifold and a throttle body with injectors in the throttle body.

In both the Holley HP and FAST systems, they make kits specifically for a LS engine, so they are relatively easy to install if you know what you are doing.
