EFI vs Carbs: Which is better?

red82gt · 03-15-2001, 05:23 PM

One thing about carb is its easy to make changes and you don't need any aftermarket electronics to tune them. If I had the dough though, I'd go to fuel injection in an instant, I get jumped on from a role (single plane intakes are a bit of a liability in this department) but from a dig that little bit of torque missing down low allows a better hook and (my car's relatively light anyways) is not missed once the tach spins past 6000 and since I drop to only about 4500 in second I'm still in the fat of my powerband.

However, for power adders tha accurate measuring of air and fuel in fuel injection is the way to go.

Here's another interesting tid-bit...Did you know that on a centrifugally blown, non intercooled motor, A carb application can run more boost because of the endothermic reaction of the wet fuel mixture atomizing can cool the mixture up to 50 degrees F. making the car less prone to detonation.
