Hi Jerry,
Yes, I find retirement plays a significant role in "time on your hands". It was either this or take up knitting....I hate knitting....
How are you making out? Ian causing any trouble?
I found out today the property we just bought in Lakewood Ranch did just fine. No power outages, no flooding. They said it was the only place in all of SW Fla where the sun was shining and it didn't rain...but I didn't believe that part.
All the Best,
Acta

We got out fairly well here in Jax.
As of 6:00pm, The wind is still howling it’s still raining but it appears to be letting up and lots of branches are down.
Tomorrow will be clean up day.
Charleston, SC better watch out. Ira is regenerating off shore.

I definitely appreciate everyone’s opinion on this thread!!!
I also like arguing thooo lol
but yes u guys have more expertise than me for sure but I still stick to my view that the eventuri is better then the stock intake…. 🤷♂️
I’ll post some pics wen the install is all done. I just dropped it off today

Be sure and have them produce dyno runs of the before and after.
I found the following video to provide a good info about air filters air flow in general.
I also did my own DIY (very basic) test to find out if the BMC filter I bought is better then the OEM one. IMO, the answer is no. However, the ability to clean and reuse the BMC makes it an economical solution. A pair of OEM filters run for $140 ( one time use) and a pair of BMC filters run for about $160 for multiple use plus about $20 per use for cleaning agent and oil.
With the ability for the OEM to support 680HP with no restriction, one can assume that even with higher HP, the OEM filter will be sufficient, IMHO.

you gotta love his, "looking at it, it's definitely better than stock.". jesus christ. thank god for these kinda guys or the world of aftermarket wouldn't be nearly as full of options as it is lol. the stock system is fantastic for both flow and for dealing with heat-soak. but hey, why not spend 3k on something that you'll rarely see and that will reduce or not improve performance. makes total sense to me. insert eye roll emoji here.

Opinions count! I learned early in life NOT to argue with a “Believer”.
Religion and politics - off limits for me. Lol. Hope you report back on your installation! I promise to appreciate your choice.

You definitely have far too much time on your hands.
You and Stenzel are better at getting to the core concepts than I am. But my assessment would be to:
- -Determine for yourself what the ultimate goal for the change is.
- -Finalize how much you are willing to pay per horsepower gain for the change.
- -Looks are subjective and the value is always subject to debate.
As a consideration, Mercedes has been designing and building performance engines and platforms for many years and is well respected in this area.
As support for Actas position and given the government and regulatory constraints they face, I find it very interesting that the GTBS Nurbergring winner comes with essentially the same intake and filter system.
It works!!

So are we comparing the modified stock system or a plain stock system ?
And I understand that for the price of eventuri you could put your money into something that will increase horsepower dramatically
But I’ll take the eventuri system over stock
Car is still in the shop but I’ve done:
Project gamma downpipes
Renntech blow off valves
Eventuri air intake
Renntech adjustable springs
spacers
carbon fibre downpipe cover
carbon fibre hood
carbon fibre side mirrors
carbon fibre full skirt kit with bigger rear wing
panamericana front grill
Stage 2 tune

One of the more interesting and entertaining threads of late.
Whilst I don't have time to give replies on each post I want to I thought I would summarise our reasons/thoughts:
Whilst I don't have time to give replies on each post I want to I thought I would summarise our reasons/thoughts:
- We don't give a measured HP increase on stock vehicles, sometimes this costs us a sale I am sure. The GT intake stock isn't so bad as say the W205 C63. The convoluted plastic inlet into the turbo causes the most disruption to flow. Nothing measurable on the C190. Hence we won't play that game. If you think you can get 40+hp increase just by just an intake swap as some claim,(c63) purchase their product. And send us before and after dyno figures. I am not prepared to churn out this kind of "data" to get a sale.
- Some HP increase claims are not even within the stated accuracy variable of a wheel dyno/rolling road. Google it. most are +- well over 12hp on the same day with no other variables.
- 12hp is 2% on a 600hp car. Think about that.
- If you are after bang for buck power for $$ get a tune. That's why we offer it with our intakes or even without.
- If you want to future proof your car for planned future mods such as big turbos, e85 etc. This is where the extra flow of an intake starts to make a difference, when you are well outside the factory engineers flow calculations.
- Open your hood and touch it above the airbox, touch the airbox too after a drive or leaving it in the sun. The main issue with IAT on all M177/8 engines is intercooling related. Not the actual intake filter air temp.
- If you want slightly better throttle response and improved visuals. An enjoyable aural experience; intake sound, turbo spool, BOV woosh, and are happy with power of the car stock. Get our intake.
- https://www.zacmotorsport.com/collec...-coldairintake
- If you have a couple grand to spend and want more power too, get the tune.

An interesting and entertaining thread indeed... I certainly appreciate and respect the post from Skilly, Acta and Stenzel .... I found some of the post comments pretty funny, Stenzel wagering a bet with his ex-mother in law as the prize if one is correct... most of us already have one of those and don't need another !! Then there's mouse nut HP at 6,000 rpm from Skilly....and Acta with the Butt Dyno, final and indisputable truth theory ...
I certainly don't have an engineering degree and have mostly survived with a touch of common sense in these considerations... 12hp out of 600hp for a 2% gain fails my common sense scale.. but It sure is a pretty system...Regarding M/B and other manufactures enginerring efforts, I have always thought there probably a touch of compromise that could be exploited for more power, (software, turbo's, exhaust systems) come to mind.. I owned at one time a 360 Stradale and a 360 Spider... Interestingly the intake systems were identical.. always found that strange but maybe not so much now after all this discussion.. but I did buy a GruppeM C/F intake box and it looked really good thru the glass on that 360.... So maybe if the M/B had a glass hood the Eventuri system would be the ticket...
Skilly, my TTS is a 2017...the list of engine upgrades is extensive.. pipes, turbo's, inconel headers and can, Sam's level 3 software, eventuri, intercoolers ++...
AMG-GT-S-2016, the pics of the Eventuri look great.. Congrats....
BTW - my GTR Roadster will be on display at the M/B History of the Roadster display at the Hilton Head Concours... If anyone of you is coming that way, stop by and ay hello....
SLcruzen with $3k to spare !

Eventuri intakes are much better engineered then the open intakes on the market.
couldnt find a video on the v8 but this shows some of the development on the cla 45s system. Lots of other informative development videos on their YouTube for other marques too.

I see the argument "well the stock system can support 1000 HP so there's no point in replacing it" pretty often, but I don't see that meaning a well designed aftermarket one couldn't perform better at the same boost levels / all else equal. Fully understand that testing back-to-back under equal conditions is the only way to know for sure, but maybe there's a piece of theory I'm missing here? Educate me please

After reading this entire thread I just had to chime in. I’m relatively new to this forum but I’ve owned my share of sports cars over the years. My thoughts:
-some people insist on dyno numbers. Others no matter what you show them will never believe. And still others believe anything that’s put in front of them (my wife is a marketers dream)
-I personally feel there is something to be said by improving the intake tract. Be it a free-er flowing air filter or a more elaborate intake system. Now do I have proof?? No. But if a filter flows more air that can’t hurt. I don’t need a dyno chart. It’s called common sense. Intuition. (Apologies to anyone who is offended by that)
How much? No idea. But I think 5hp for anything is reasonable. Anything more is probably BS.
-my son plays baseball. I tell him singles and doubles all day long. So 5-10hp here and there and pretty soon you’ve got some real numbers. Is it as cost effective as a tune? Of course not. BUT a tune will most likely invalidate your warranty. Something to think about.
-as for this hot button issue of open vs closed. I think it’s overblown. If you search the web regarding IAT at the air filter the difference between the two is 2-3* at most. Now if you use the rule of thumb of 1% horsepower increase for every 10* then we are talking about 0.2-0.3%. That’s 1-2hp at best. Well within the margin of error. I feel the intercooler is more important here. After all, that air still has to go through the turbo.
-so what does this all mean? Go with whatever one you like. Filter, open system, closed system. What looks good. What sounds good.

Flat gains, 5hp gains, or 5hp lost, its money spent on a PREFERENCE, and should not be further justified with some dubious performance gain statement (it looks performant...wait, what?!). What makes this more entertaining is the cost - $3,000 USD for the debatable performance gain is akin to lighting up money in your fireplace, literally. Much easier just to do it because you like it. Being confused with the facts and deciding that this is for performance and you've wasted your money, The forum is really build on sharing ideas and choices (look what I did!), but just as important, is the information sharing needs to strive for accuracy. In fact, most of the data that I have collected for the steps I have taken with my cars is often rooted in reliable information coming from these posts. So, we all celebrate choice and individuality here, but not 'alternative facts' to justify a decision to purchase something.
This debate going on...its like this: I have these awesome exhaust modifications for sale - found them at Walmart. You add them and they add 5hp. Its real because I can hear them working.

“Flat gains, 5hp gains, or 5hp lost, its money spent on a PREFERENCE, not because it provided a performance gain.”
Basically the same thing I said. You get it because you like it. Obviously the most economical way is a simple filter swap. Anything beyond the involves dropping some $$$ and just deciding what you like.
TO EACH THERE OWN.

You can go and fuel your fireplace with $100 bills if you want. I think the hundreds will burn just as well as the local newspaper. This debate is very VERY weak.

- The argument stating "the stock intake is able to handle 1000hp and is therefore fine" is very much valid, and akin to "newspaper burns great, so there's no practical (non-preferential) reason to use $100 bills"
- The pro-aftermarket intake argument is akin to "but using $100 bills burns a bit hotter [practical], and it looks better [preference]."
These 2 arguments clearly conflict re: practicality.
Translated back from the analogy, the argument of "stock intake can hold 1000hp and is fine" to me does NOT invalidate "aftermarket intake makes slightly more power."
The seeming confidence with which the 1000hp argument is posed as invalidating "aftermarket intake makes slightly more power" makes me wonder if I'm missing something about this line of thinking.

I think the debate is a bit different than how you've framed it. IMO it's more like:

The 1000hp argument isn't to sway someone from purchasing it. Rather its a cautionary note that is saying "if you are buying it for a performance advantage, you are wasting your money". That I can get behind.
