Just wondering if anyone here run the Needswings intake on their E55? Any before and after dyno testing?

99lightning

be nice to see dyno and drag times on that. maybe they can send me one to dyno test but no one likes that idea ever

SavMan

I had before and after dyno's and runs but difficult to compare the actual numbers for the CAI due to other mods at the same time

I went from this

176mm Crank Pulley, 82mm TB, PLM Headers, Kleeman Cams, Ported Heads, X-Pipe, Secondary decat, Eurocharged HE, Eurocharged ECU, Renntech V3 DLM

to

176mm Crank Pulley, 82mm TB, PLM Headers, Kleeman Cams, Ported Heads, Needswings CAI, TTM Scoops, 3 inch Exhaust, X-Pipe, No Cats/Resonator, Eurocharged HE, Trunk mounted tank with spray bar and 2 pump system, Eurocharged ECU,Renntech V3 DLM.

So basically lost primary cats and Resonator with 3 inch exhaust, trunk mounted tank with split and Needswings CAI with TTM Scoops

I dropped 0.3 secs on the 1/4 and gained 35 RWHP, most of this would have been decat and split cooling, what I can directly contribute was that before the CAI I had a 0.1 bar / 1.5 PSI vacuum intake depression which was the reason for getting the CAI. With the CAI I no longer had the depression.

Was that gain under the curve or peak, that is substantial and your drop in ET backs up the HP increase.

The split cooling may not have made a difference on the dyno because if you guys waited a while in between pulls, the IATS may not have gotten that high, and timing might not have been pulled.

Now at the track, having the trunk tank would have played a big role.

I have the NW Intake, but have not dyno'd since install, last dyno was after headers.. However, after I buy your TB I will re-dyno.. One thing I can say is SC whine is more readliy apparent and on the open road response seems quicker...

SavMan

Previous dyno runs and 1/4's runs were affected by heat, IAT's would hit 170-180F in 8-9 secs. They spent 2 days on the dyno measuring airflow/temps and coolant flow/temps.

They identified 3 things

1. IC Pump was working but flow was poor they also suggested to split cooling and run trunk tank.
2. Exhaust had 4.5 PSI of back pressure this was taken after primary cats
3. Stock intake resulted in a 1.5 PSI vacuum

Gain was under the curve and also resulted in 3 to 4 mph increase in trap speed.

At the time the guys that did the tests suggested I had at least 50 bhp peak to be made.

I have one on my E55 motor, I don't have dyno test but i do have 1/4 mile track test.

This was
I was running 11.5 to 11.7 @ 116 to 119mph with stock intake
the next week i got the Needswings intake.
I now run 11.2 to 11.4 @ 124 to 126 mph.
there were no changes to the car other than the intake.

as for as trying one at the track or Dyno,, I will have a Needswings intake that fits the E55 and or the SL55 at the Dyno day Dec. 1 in south fl

you want to try it come on down I have the Y fitting that fits the stock throttle body and i have one that fits the 82mm throttle body. Jim

You had a change of up to 10 mph in the 1/4 with just an intake?? There has to be another varible in it than that I would think. My evo runs 11.20's at 122 and hitting a 75 shot from 60 ft on only gives me 5 mph. At your weight thats another 66-74 hp. That would be pretty awesome from an intake. Are they the guys who use to make srt4 parts?

PACougar

I've got to agree with Jason, those kinds of increases in trap speeds are what we would expect to see claimed on a Honda site about an intake I'm not suggesting you're misleading us, I simply believe some other variables were at work between the two track days.

Kreuzfeuer

The 119-124 gap seems more believable, it's hard to speak in absolutes when comparing the two extremes. I've ridden in Jim's Crossfire when it had the OEM Mercedes intake on it, and while still a beast you could definitely tell it was choked back a bit (we don't have the same core support design).

Answering Jason's question, yes -- this is the same company that made a slew of mods for the SRT-4 platform. They also blew up big when they started tuning for the SRT-6/SLK32 crowd. They've helped put nearly a dozen Crossfires in the 11's.

Previous owner of my car ran 13.15 @ 106 (bone stock). With a NW single, he ran 12.89 @ 109.5.

With the addition of 65mm Eurocharged pulley and ECU tune, I ran my fastest official time (12.3 @ 111.9). I've since installed the NW dual intake, good for another ~200cfm and tons of low-end grunt. Haven't been to the track since the upgrade, but the car feels STOUT.

During the summer, I was playing around with another intake mod, and I lost (as in, ran slower) 3-4 tenths in the 1/4 mile by removing only the NW intake and replacing it with stock boxes and C3 rear intake mod. So, there's definitely something to it.

All the best,

John

PACougar

John, are you saying that the core support is the main issue on your platform for the intake? If that's the case then I could believe if you had some huge restriction that perhaps we don't have you good see much bigger gains.

99lightning

id like to get my hands on something like this but not for that money oh i can have that done wayyyyy cheaper and at least give real results

Kreuzfeuer

Yes and no. I probably did a poor job of explaining that, haha.

Factory setup (on the Crossfire) has two 2.5" tubes leading to a 1.5" elliptical opening that passes through a baffle in the core support. Combined with the stock paper filters, the net flow rate is ~440cfm. The Needswings single 3" CAI (routed through RH side of core support) flows ~600 cfm with the K&N filter, and also eliminates the restriction on the core support. With the baffle removed, the 3" diameter fuel hose used to join the filter to the intake tube passes through cleanly -- it is deformed slightly in the pass-through, but not pinched down in any way. Think "ellipse" versus "circle".

With the dual CAI, the effect is repeated on both sides of the core support, yielding an additional ~160cfm over the single (depending on the filter you use). This is why the gains are so huge on the Crossfires. With a dual CAI, we nearly double the supply of cool air that the blower gets.

Ignoring core supports, the SL55/E55 AMG intakes only flow ~525cfm (many of the Crossfire guys use them as an inexpensive upgrade). Jim was using this intake when the V8 conversion was first done...

So, the NW intake is a definite increase in cfm over stock E55 boxes, even with the E55's superior OEM core support pass-through. Throttle response is improved, sound is improved, and the air travels in a much straighter path. Many people even see IAT's go down with the NW intakes, an unexpected benefit.

The hassle-factor alone was worth it for me -- factory boxes get clogged with bugs, leaves, other debris -- and the only way to clean them is remove the intake system. I run the K&N dry sock on the front of my filters (they only steal 1-2cfm from the flow) and the filters stay pristine, even though they're mounted directly behind the grille.

Cheers,

I am looking forward to this. Hopefully someone will take you up on the offer and put it on their car to see the gains.

It's not that hard to swap the stock air boxes back. Ten minutes top for me.

Denroll

So, what is the best intake option for the E55?
This looks like a decent, well-made kit, if not a little on the expensive side. I'm looking at the intake as my next mod.

Hammer Down

Some say the stock box is more than fine, some swear by Renntech's box while others including myself have custom setups. From what I have seen most them produce the same amount performance on the track.

amx1397

this is the Needswings intake on my car.
the filters are in the large bulge next to the manifolds

RedBullJnky

I'm going to do a pull with out the NW intake and then one with it. Just so that we can all see the difference.

Hammer Down

Elliott what type of box are you running now? EC or RT?

Triman2008

I personally am woking on a custom intake setup similar to the NW. I am making mine of 4 inch pipe from inlet to TB. The TB will will be the bottle neck area.

Hammer Down

Interesting, I think 4" may be too big given the size of the opening at the radiator but the again you never know keep us posted and run it down the track to see how it performs

SilverStrk

RedBull,

Post your results from your pulls.. I'm curious, because my butt dyno says something is there, how much, just can't tell.

RedBullJnky

I have the Carbino python tubes and air box. Got them from another member.
That's why I'm doing it. Will do.

abl2fly

I am doing a 3" setup on my CLS55. It will be similar to the needswings, however I have had to modify the radiator inlets heavily to fit the three inch setup. With that said, it should make good power. Will post before and after dyno when it is complete.
