Revision to New Era OTR intake make more horsepower!!

[mike@newera]

In an effort to continually improve our products through research and development, we made some minor changes to address the inconsistant driveability issue with our kit on the stock tune almost a year ago the MAF sensor location, and have since then not had any feedback reported with stock calibration installs. However, we still reccomend a custom tune because every vehicle responds differently and it will maximize efficiency, and anyone that is a tuner should reccomend a tune with any intake install if they are doing their job.

So, how could we continue to further improve this unique product? Well, not only did we make an improvement that gained 2-4 rwhp in back to back testing on the same car today on 4 dyno pulls all done within one hour for accurate testing, but our current customers that already own one of our OTR intake systems can also do this themself! A simple change to the air filter position, by taking out the air filter and reassemlbing it installed in the opposite direction, it increases airbox volume by over 15%! And allows more direct airflow from the air filter to the eliptical tube entrance.

Here is a picture of how the air filter is now positioned, protruding outwards instead of inwards:


Here are the dynographs of the testing:


The testing was done with our shop project car which is an L99 with cam and heads, here is what the graphs represent:

Runfile 001 = We installed a brand new production OTR intake off the shelf, and dynoed it
Runfile 002 = We reassembled the intake with the air filter in the opposite direction
Runfile 003 = We pulled a different production OTR intake off the shelf (for sake of comparison and consistancy between production products) and installed it the way it was
Runfile 004 = We then also reassembled this kit with the air filter in the opposite direction

All testing was done in the exact same conditions, same car, within about 1 hour of time, so the results are very accurate, AFR did not effect the power increase.

For our current customers that are using one of our systems, if you are going to do this alteration, please either clean the filter extensively, or purchase a new air filter for your kit to prevent debris entering the engine.

Even though I run a different OTR, it's nice to see any vendor listen to the customer and make improvements. Kudos

I agree! I had one of New Era's early production units last year and I returned it due to drivability issues. I didn't want to tune and it became apparent that a tune was the only thing that would help. Mike & I didn't quite see eye to eye at the time but that's water over the bridge! I'm really glad he's working out the bugs and passing on the improvements to his customers!

I'm planning on upgrading to a 102mm throttle body eventually. If I buy this intake with the OEM TB will it still fit when I make the switch?

Its between this and vararam- What was the baseline of this car with mods besides the intake? trying to gauge what gains the intake sees.

You will just need to change the silicone coupler, that's it.

Ummm, Vararam is in your sig already...

So, almost a year ago, ya'll changed the position of the MAF sensor? Do you have any before/after pics of that change? I'm sure I have the earlier version, but would like to see what the difference is. I haven't had any drivability issues that I have noticed, but then again, I am still using that airflow plate thingy too that sorta blocks some of the direct airflow. Maybe that's why I haven't seen any issues. I will definitely flip my air filter around, thanks for the tip, this is the first I've heard of that!!!

Edit: Actually, according to the dates, that MAF Sensor change would have been almost two years ago now!!! I'm curious which one I have, maybe I do have the newer version?!?!?

The MAF location change was so minimal, you would never be able to tell by looking at a picture. The prior driveability issue was only noticed by about 1% of our clientel, a certain driving condition would have to be met for it to happen. We did further testing to find out it only occured in Jannety's test because his fan generates a 65mph wind. This is not a variable speed fan in comparison to the mph in which the vehicle is travelling at which made the throttle transients and load , in comparison to vehicle speed not have an accurate effect on our intake, causing the airbox to somewhat have air forced in faster than it was taking it in with hardly any throttle, and create air turbulence at very rarely seen engine load in correlation to front grill air speed. This effect would take near like hurricane conditions to be duplicated due to the very light part throttle scenario at such a high wind speed, or just the right driving habit with incorrect calibration. Not trying to take anything away from Jannety's power findings, just that we figured that out after it was brought to our attention from his test, so we made a very slight change to try and get rid of this so called issue that was reported back to us on only a few occasions.

Sig hasnt been edited- had bought one and it wasnt made to fit the 2012, which wasnt told until after the purchase was made....

anyways thats besides the point.........can you answer the original question..?

It wasn't tested with the mods and a stock intake, this car made 479 rwhp last time it was on the dyno with NEP OTR intake, NEP VVT cam (found some more power in the calibration with this too a few months ago, as we are constantly trying to improve), Darin Morgan ported heads, ARH 1 7/8 with cats. So, I am sorry I can not truly accurately answer your question because I don't have real data. It will most likely be a rare occasion you find a vehicle making 100 rwhp+ over stock with a stock intake, not saying it is impossible, but I doubt it.

Understandable. I was just curious how this stacked up against the vararam. Same concept- I just like the look/ design of this better. Is it available in different colors, or do you guys carry just one color?

[mike@newera]

Raw finish (which can be painted or powder coated whatever color you like after you receive it), flat black, or black chrome (gun metal like finish).

[mike25]

Sounds good. Do you know of anyone who might have done a seperate dyno on this intake by chance?
