Anybody swapped from an airgap to a victor on 360
10-4! FWIW, that’s exactly what I thought too until in a similar discussion with someone here on the forum that picked up .3 on an 11:1 340 4 speed, 4.30 gear Duster over an air gap. He said they compared it to a TM5 and it was similar except the TM5 was deeper with slightly taller runners. But I won’t deny that the pinch points make both designs extremely dated and inefficient, and it would probably be worth a few more tenths to use the Torker II or Xcellerator. In the great tests of intakes, I have never seen a TM5 dyno’d. But I have noticed that there is always a ton of the manufacturers advertising for the airgap which always comes up as the second coming...
In my opinion the Air Gap is overrated.
First I agree with flyfish.
Nailed it!
And, well, here is my take.
Each new intake design is an improvement over the last. The product would be worthless if it didn’t do so.
It is not the case of not being able to produce decent power or run fast with any old intake but a matter of choosing the right intake for the job, new or old.
The RPM is not over rated IMO but correctly inserted in the pecking order via reputation and time slips to where it should stand. This should not discredit the older LD-340 or belittle the basic Performer. The RPM simply performs better.
From this site alone, there have been a few members posting there slips with there equipment. If you read them carefully, take into account the cars weight and the overall build, coupled with what category the car fits in, the RPM is normally a GREAT choice for most of us here down to about the mid to low 11 second zone.
The more “race oriented” rides benefit from the single plane.
The question now becomes, Is the car more of a race car? The question of weight comes into play. As well as converter, launch RPMs, torque needed to leave the line at the quickest it can, etc....
