great product...great results...love it

Anybody local that has this box wanna let me test fit this on my car before I waste my money?

E55 RUSS- Target AFR doesnt change with mods.

I think you have a valid point here about the air box not helping a stock car. Last fall during a local track day event, I raced another E55 with a VRP air box. He was stock otherwise and I was completely stock. My car was definitely faster. I beat him twice by at least a car length, maybe more. I would think that the cars should be close in stock form and if the air box was to help, he should have beaten me.

Nice numbers!

In order to better understand the true effects these air boxes brought to jakpro's car, we would need to see the associated A/F chart as well.

My car is currently being dyno tuned and after some experimenting we noticed that when we leaned up the fuel maps we experienced a 12rwhp gain from that alone.

Although, about a year ago I did a dyno after I replaced the stock HPS air box with the AMG55 boxes I noticed a 26rwhp gain. So out of experience I can confirm that: Yes it is possible to obtain this level of power with boxes alone.

It'd still be nice to see those dynos with their appropriate A/F ratios attached.

Mind telling me where you are getting dyno tuned on the east coast? Did you see a gain form the 55k airbox to the 63 airbox?

You're getting dyno tuned at a location so secret that it can't be revealed in public?

E55 RUSS

Are you serious..How come is that...Car with extra promised power from VRP AB and tube should have been faaaster may be it had 20inch wheels or something was wrong with it...

Tech-Tune

The tuning facility currently houses over 30 tuned Ferrari's, 2 Lamborghini's, and 3 Benz's. My tuner had asked me to refrain from disclosing it's location publicly for security reasons.

Besides, this is Vadim's thread and I prefer to keep to the discussed topic.

ProjectC55

I believe and Alex could tell you that the 55K boxes and 63 boxes are basically identical.

ProjectC55

Well Alex I guess we'll be talking at the meet,beecause I'm interested in finding out if they could tune the Bosch ME 2.0 computers.

We did not perform a scientific test with a before and after comparison. It certainly could have helped his performance and there could have been a bigger difference without it. I am thinking that if the situation ever comes up again, we could run, swap air boxes (mine and his) and run again. That should be a fairly accurate comparison. I will say one thing about it, the quality is definitely first class. It is a thing of beauty.

Tech-Tune

OK, I cant stop thinking about the HP gains. Those gains are just too big for a simple airbox swap.

The only way the VRP airboxes could add that much power is if he was running the 74mm splitter, AND THEN you guys upgraded him to the 80mm version of the VRP Boxes. Otherwise, please explain how the heck they made that big a difference, because it just doesnt make sense to me.

Vadim @ FD

Tech-Tune: Tech-Tune: I do not understand what you are asking.

Jakpro1

I don't have half the expertise that many of you have on these issues, but I can tell you this. (not that any of you are saying contrary to this at all, but I just feel it needs to be said)

Vadim has been around for quite a long time and has proven to be a man of integrity to me time and time again. I have always been a big fan of Vadim and if Vadim says he put the airbox on the car and it made the hp claimed, I take him at his word.

We do not have much information on our motors with ported and polished heads with higher lift cams. Not sure if I was the very first to "street" ported and polished heads but I certainly was near the top of the list. I noticed and still maintain that the car ran more responsive with the mods, but when we ran the car on the dyno we noticed that she was running ultra rich and was throwing a sporatic CEL light for MAP sensor. Perhaps this is what the car was struggling with. The lack of required intake air combined with an ECU that was freaking over the amount of increased flow already coming in.

I still have a dream of opening up the Y pipe as wide as possible and plumbing an intake straight up to a cutout in the hood for near perfect cowl induction point. Just a dream right now.

chiromikey

although it gets glossed over every time i mention it, i've been babbling about this for a long while but no tuners have really paid it any attention. you better let me in on it if you're doing this behind my back!!!

Tech-Tune

Vadim, I experienced a extra 26rwhp after my swap from stock HPS boxes to the AMG55 boxes.

To me, this gain seemed enormous.
So I later removed the AMG boxes to compare the duct openings from one box to the other. I found that the HPS boxes were 6mm thinner in diameter than AMG's at the TB port. Thus my enormous HP gain was contributed by the extra 6mm in intake diameter.

This is why I'm guessing jakpro had a 74mm splitter prior to your air box swap. Because he experienced the same increase in power as I did when I swapped boxes.

Look, the maximum amount of airflow is equal to the intake system's thinest passageway (especially when discussing forced induced systems)

So I guess what I'm asking is:
How did you get such impressive HP gains on boxes alone?
Are the intake ports on both boxes the same diameter?

Thanks.

Havoc

Perhaps the reason JakPro is seeing such high gains from a simple air box swap is because of his stage II heads.

Jakpro1

Hopefully I will hold the title for highest hp 5.5, til the Hav monster emerges.

It'll be the greatest 2 1/2 weeks of my life.

That bout it Havoc? How close are we now?


**********

EDIT, Heyyyy, wait a sec. You're car is NOT gonna be a 5.5 anymore, it'll be a 5.7. WAAA WHOOOO, I'll still be the champion in the 5.5 class.

joshd

I'm definitely going to be purchasing one at some point, but it would be nice to see the associated AFRs as Tech-Tune mentioned for the above chart just to see how much power was gained (if any) due to a leaning of the AFR versus elimination of airflow restrictions.

Havoc

Hey Jim, Your 5.5 has waaay more hp than I currently have. I don't even have 1hp and I can't even drive up onto a dyno!

Yeah, I'll give you the 5.5 title.
I'll be in a class of my own until someone else steps up to the 5.7. But even then, Good Luck to whom ever will follow me cause Victor, Vadim, and I will not stop until we reach at least 900hp!

Vadim @ FD

No, both cars have 80 mm TBs. It was a very straight install.

I was actually hoping for more. Stock air boxes are ok on a stock car, but once you add another 140HP, they will not have enough capacity, even with K&Ns.

Screw type blowers are very touchy to inlet restriction, they make boost right off idle, so they need all the air you can give them.

I am thinking of making a new type of intake that can feed the blower even better than CF intake. I will post more pixs once I am done.

Havoc

Thanks for looking out Vadim!
..So this new type of intake will be more efficient for when the twin turbos kick in from the rear at high end...
