I was there to witness it too. I was shocked as I couldn't believe it myself. It was a friend of mine E63 so I was there for moral support...ordered them instantly for my C63. Will have Dyno results soon for mine too plus some other upgrades I am doing with the guys @EurochargedATX

Be interesting to see more than 1 dyno result to back up these claims....

If one has a strut bar, will it still fit? Are the airboxes actually raised by much?

PACougar

No idea about the strut bar, measure the gap between the bar and the boxes. The spacer raised the Air Box about an 1". Don't forget your motor moves, you've got to leave some clearance for that as well. We did 3 runs before and after. Baseline was 441, 440, 446. After runs were 463, 464, 467. That graph is highest before and after.

shardul if u want to send me a pair I will do a 3rd party dyno run of my car and video it without stopping while I do before and after and only swap out the spacers in between pulls.

I'm running pro drys with row boxes

PACougar

Just to be clear, Shardul didn't ask us or pay us to dyno this car. This was 100 percent customer driven.

Hopefully I can get my C63 on the dyno by late next week as it is still hard for me to believe. The order went in today for the Intake Spacer.

thesaintusa

Impressive.

Not surprised to see some improvement.

Surprised to see that much of a gain, but can believe it.

Nobody would allow somebody to 'obstruct' their intake, so removing an obstruction would only benefit.

As I said, sometimes the most obvious bottlenecks are overlooked. Similar to how the ROW intakes make a difference for the same reason that these spacers make a difference. More flow

I would like to see these spacers on stock intake boxes.

wikiwiki

I have my ROW's sitting next to me and not yet on the car. I will see if possible I can Dyno the car @Eurocharged ATX before I put the spacers on. My plan was to dyno after with the ROW boxes as I have a base already, base+tune dyno'd and soon base+tune+ROW+Spacers. Hell, Maybe I can just rent the Dyno for a day and we can get folks with the M156 engine in to test different configurations? Crazy thought but possible?

I see the filter restricting my eyesight, but air? How is the filter element be retricting the air?
The only way is the material iself.

I'm struggling with this.

Perhaps if you dyno'd before the spacer, then again after the spacer, then once more back to stock it would prove if there was a benefit and not just variance between runs. Also, performance filters don't appear to make any difference either but again happy to be proven wrong with a before/after/before dyno combo.

For what it's worth, my car felt a little low on power at one point, as you generally tend to notice as a regular driver of one car. It wasn't quite due it's air filter change but I did them anyway (stock filters, ROW air boxes - As I live in the ROW anyway). When I checked the filters, they were pretty dirty to be honest so, to my delight when I bolted everything back then car ran like a champ and hasn't stopped since.

There's a lot to be said for keeping your filters clean. This engine like A LOT of air, so as a consequence the debris on your filter is going to build up more quickly, at least more than I'm used to on previous cars, admittedly with smaller engines.

skratch77

if you are going to do this install the row boxes and what ever filters you are using and do a dyno.then only install the spacers after first pull and have the only variable being the spacers.i install the spacers while the car is strapped in the dyno and do another pull

I would also use another dyno as the one you picked is affiliated with the people selling the spacers.again try to keep it 3rd party.

also post all the dyno info like correction factor and all the conditions on each run so we can see they were not adjusted.

forum member with M157 also picked up about 20whp over kn's with this kit

Those sneakers are gone unfortunately.

I'm still super skeptical about this product, but if these dyno results keep coming in (no offense, but I've never seen any of you guys on this forum until you started posting up your unbelievable dyno sheets, so I'm going to hold back my excitement until I see a board vet put up numbers that I trust) I may be swayed... Good job guys.

PACougar

No offense taken. Feel free to look around, I've been on this forum for over 5 years. You can take a look at threads I've contributed to in the past if that helps. Better yet, if If you're ever in the Austin Texas area stop by and you can operate the dyno

thesaintusa

Consider the improvement that the ROW airboxes offer, and how the improvement in design (less obstruction) yields results.

Why is it so hard to imagine that further improving the airflow will yield further gains?

Air still has to flow into the box, and flow will be increased if there is no obstruction. If you can see it, it will have influence the flow. No different than how people just post pictures of the difference between the ROW and standard air box, and we all just nod our heads in agreement and say 'yes i can see the difference'.

I have no stake in the game, do not even have ROW boxes. I am just confused how people accept one thing but not another, when both modifications are improving the same thing -> air flow.

Bigtickets

I'm always skeptical about "bolt on" power gain claims as well. However, I've been around here for a minute or two (been away due to house flood repairs, etc) and I have worked with Shardul before and he's always been spot on. That being said; Jim, I agree with you and the proof is in the pudding. Let's see the dynos.

tpliquid

i went to the site and saw 450 wow

thesaintusa

$450 for that kind of gain is pretty reasonable, as it is just a bolt on.

glennhl

Hahaha, couldn't agree more. It's like the new oil filler cap I got that guaranteed 30 hp gain. I put it on and nothing, but the company told me I had to get a tune to see the power increase. Did the tune and sure enough, that oil cap was worth 30hp!!!

skratch77

can you post the 2 dynos with all the run information for both runs.like temps , humidity, baro ,air fuel and correction factor

PACougar

Here's an Uncorrected graph and the graph that's using STD correction. I added in the weather stations temp that's used as part of the correction. As you can see, the before run benefited from the correction because it was a bit warmer. The uncorrected number shows even bigger gains for that very reason. Of course that's why correction factors exist. Dynojet's software does not allow independent correction factors for multiple runs on the same graph, so you can't cheat by having different corrections for two different runs on the same overlay. I hope this helps you understand how a dyno and the software work.

skratch77

I know how dynos work and I'm assuming it's your dyno?can you load up both runs and overlay them showing all conditions on both runs? here is my e55 vs my c63 and you can see all the conditions for both runs on the bottom of my dyno sheet.

on a side note thank you all for the orders placed today though EC ATX
