**Installing the Short Ram Air Intake: A Test of its Performance**

The short ram air intake was installed and tested to evaluate its performance on a vehicle. The test was conducted over two runs, one with the stock air intake and another with the short ram air intake. The first run was taken from 20 to 40 miles per hour in second gear, with an average time of 4.43 seconds for the stock air intake and 4.41 seconds for the short ram air intake. This resulted in a percent difference of 0.63, indicating that the short ram air intake was slightly faster than the stock air intake.

**Temperature and Humidity Effects**

The temperature difference between the two runs was relatively small, with a change of only 17.8 degrees C from the first run to the second. This suggests that there may not be a significant impact on performance due to changes in temperature or humidity. The humidity levels also showed a decrease from 56% to 52%, which is within the range that would likely have minimal effect on the test results.

**Second Gear Run: Breaking Down the Performance**

The next run was taken in second gear, from 2000 RPM to 6000 RPM, and broken down into smaller intervals of 1000 RPM. This allowed for a more detailed evaluation of the performance across different rev ranges. The initial low RPM range saw no significant difference between the stock air intake and the short ram air intake, with both delivering approximately 1.33 horsepower at this point.

However, as the revs increased into the mid-range (2000-3000 RPM), the short ram air intake began to show its advantage. At this range, the short ram air intake was 3% slower than the stock air intake, indicating that it may not be the best choice for drivers who spend a lot of time in this range. The high RPM range (4000-6000 RPM) saw a significant improvement with the short ram air intake, delivering an average power output of approximately 1.32 horsepower.

**Comparison and Conclusion**

Comparing the two runs, it is clear that the short ram air intake performed well at higher revs but struggled in the mid-range. The difference between the two was particularly noticeable from 4000-6000 RPM, where the short ram air intake outperformed the stock air intake by approximately 2.42 horsepower.

The conclusion of this test suggests that the short ram air intake is best suited for drag cars or track cars, where the engine is kept in a high RPM range for extended periods. For daily drivers who spend most of their time driving at low RPMs, a short ram air intake may not be the best choice due to its performance decline in this range.

**When to Use a Short Ram Air Intake**

Based on the results of this test, it is recommended to use a short ram air intake for:

* Drag cars: The high RPM range used by drag cars makes them well-suited for a short ram air intake.

* Track cars: Similar to drag cars, track cars are also likely to benefit from a short ram air intake due to their high-speed nature.

On the other hand, a short ram air intake may not be the best choice for:

* Daily drivers: Due to its performance decline in low RPM range, a short ram air intake may not be suitable for daily driving.

* Freeway driving: For drivers who spend most of their time on freeways and use the mid-range for extended periods, a short ram air intake may not provide enough benefit.

Overall, the test results suggest that a short ram air intake can be a worthwhile upgrade for certain vehicles, but it is essential to consider the specific needs and usage patterns of the vehicle before making a decision.

"WEBVTTKind: captionsLanguage: enhello everyone and welcome in this video I'm going to be testing a short ram air intake on my 1999 Acura Integra GS now if you haven't already watched my video on before and after removing weight from my Integra and then doing acceleration testing you may want to check that out first as I go into detail of how I run these tests and how I determine whether or not there's an improvement so let's discuss what we're going to be looking at we're going to have a stock run a run with the short ram air intake and then we're going to check out the percent difference between those two runs and so I've got multiple different tests that we're going to be checking out the first of which are the two common ones that I do 20 to 40 miles per hour in second gear and then 20 to 40 miles per hour in third gear the 20 to 40 and second tests your mid to high RPM range your 20 to 40 in third tests your low RPM range so let's go ahead and look at our 20 to 40 run in second gear with the stock and then with the short ram air intake so our average run for stock was 2.87 seconds our average Run for the short ram was 2.88 seconds these numbers are rounded here but I didn't use rounding in my percent difference and our rounding in the percent difference comes to 0.39 negative so there's actually the short ram air intake was slightly slower but this isn't really a big difference so we're talking pretty much the same thing before and after installing the short ram air intake so let's take a look at the third gear run from 20 to 40 miles per hour foreign okay so the stock run averaging 4.43 seconds the short ram 4.41 and this gives us a percent difference of 0.63 so the short ram was slightly faster in the low RPM range but once again these are very close numbers um so there's not really a significant difference there another thing I should note the temperature difference between these two runs for stock was 17.2 degrees C for the short ram of 17.8 so basically I ran the test installed the short ram air intake as fast as I could and then went out and ran it again so uh the temperature didn't change too much humidity went from 56 down to 52. so there shouldn't be too much influence from temperature and humidity on this test so I wasn't really satisfied with seeing that there was no significant difference of the short ram air intake at all whether it was from 20 to 40 uh in second gear or in third gear so what I went ahead and did is I did a second gear run from 2000 RPM to 6000 RPM and then I broke that up into 1000 RPM intervals to look at across each small rev range did anything happen to the power band was there more power at certain parts of that RPM rev range so let's go ahead and check out the video for that all right foreign okay so here's where we have some interesting results that we can break down by our PM range so for the low RPM range stock 1.33 versus short ram 1.32 the percent difference 0.63 percent faster with the short ram in the 2K to 3K rev range our mid-ref range however was much slower three percent slower uh with the short ram than with the stock air intake and then going into our high RPM range this is where the advantage of the short ram kind of shine through so from 4K to 5K an advantage of 2.42 faster in the highest RPM range from 5K to 6K actually a 3.32 percent uh faster so the short ram is improving the high end of the Rev range as far as the amount of power you're producing now one thing I will say which I found interesting with the data is if you look at the third run from 2000 RPM to 6000 RPM versus the first run from 2000 RPM to 6000 RPM it was 1.5 percent slower and I think one of the reasons for this is probably the fact that that engine is getting pretty hot after these High Rev range runs and that heat is directly feeding back into the system so now I don't know uh long term you know if you're on a track and you're just continuing only hammering on the throttle if this is going to keep dipping down but what we do know is that you know from a normal circumstance where you're not hammering on it all constantly you're going to have more power at the High Rev range and you're going to lose power in the mid-ref range and then the low end is pretty much going to be unaffected so let's talk about some conclusions when should you use a short ram air intake if you so choose to well for drag cars it makes a lot of sense because you're going to keeping your rev range into high RPMs it's going to be one short run and then you're done with it for track cars I also think it's going to make a lot of sense because you're going to be staying in a high RPM range rather than you using those lower RPM ranges now you may have heat eventually build up within that engine bay and that may deteriorate the performance somewhat but I think due to how high these percentages are you know two and three percent is somewhat significant for only changing just one small component such as the air intake so I think it's probably going to be worth it in the long run even if you do have a little bit of additional heat if you stay within the high RPM range now what is this short ram air intake not good for and I think the perfect thing that you would not want to install it in would be your daily driver you know you're going to be using your low RPM range way more than your use using your high RPM range when you're just driving around the city especially your mid-range or you know when you want a little more power when you're getting onto a freeway you're going to use that mid-range and you're going to be losing power in that situation so if it's for a daily driver I'd recommend against using a short ram if it's purely a track car it could be a significant benefit any questions or comments feel free to leave them below thanks for watchinghello everyone and welcome in this video I'm going to be testing a short ram air intake on my 1999 Acura
