The 80mm tb gives the car huge low end torque and the transmission will change gear from 1 to third/fourth gear fastly when you accelerate at low rpm but hp talking i went back 6 hp on the same dyno and similar ambient temperature, don't ask me how this is what hapenend with me.

Lenin

Hi Rob, I can confirm the same. Huge low end torque. I love it. Not sure if it's the 80mm TB alone or a combination of the NW Intake, the modified manifolds and the TB, but I like it a lot.

320 dreamer

can you show me a pic of the 80mm t/b and the t/b intake you are using?

Lenin

Here is the TB intake
Don't have a picture of the TB itself but it looks just like any other TB. I used the one from the SLR/CL600. A1371410125. Same setup as RobertAMG had when his car resembled a C32.

Can someone check for me why Jerry is not responding to my mails from 2 weeks, the car is waiting in the garage since, if there is something personal?

Lenin

Jerry must still be recovering from the party they had to celebrate the opening of the new shop.

chris.bachman

Robert, I sent Jerry a text for you. Let me know if he doesn't get back to you in 24 hours.

FYI that's me on the horse.

320 dreamer

is that the oem 74 mm t/b intake housing in red? how will you adapt the 80mm to it so the flow is 80mm?

Lenin

Yes, it is the original 74mm TB intake housing. I ported it to have an 80mm opening and had "ears" welded on to accomodate a different bolt patern. Same setup as RobertAMG, just in red and teflon coated inside. How are you progressing with your 82mm TB?

Nice ride

320 dreamer

in the air for now. the t/b housing is nthe issue and im still working with a new tuner getting the new files is a handful.

Any updates on people that have recently installed the NEEDSWING CAI?

Ken311

i ordered the CAI beginning of last week so it should be shipping out late this next. when i get it installed i will report back with some pics and a video

Anyone have Dyno numbers running fully stock but for the needswings CAI?

Lenin

Why would you do such a thing? For more or less the same money your first performance mod should be a pulley and a tune.

Kreuzfeuer

We've had many members (both SRT and SLK) do the intake-only option with excellent results. It has been long-debated which route is best, but everyone eventually gets the trio (CAI, pulley, tune) within a fairly close time-frame anyways.

Pulley and tune w/o intake mod yields an air-starved (aka rich) motor unless the ~440cfm flow of the stock boxes is taken into account with the tune.

CAI with no pulley, no tune has yielded results as good as .3/.4 quicker ET's, the car runs a bit leaner but the OEM mapping is slightly rich to begin with.

Clearly in either case, a tune is advisable to get the absolute best gains and safest AFR's.

I know right now, I'm between intake setups (was trying another one for a brief spell) and Steve advised me to go easy on the car because it's tuned for a pulley + Needswings CAI and I'm running stock boxes this week until I can iron out the other intake.

Many schools of thought on this, and since EC offers retunes for free, no bad way to go about it.

Lenin

Who needs a dyno. Here is your answer from the track.

If things were just this simple. On a stock C32 with just the NW DCAI you will not do better than 0.2 secs 1/4 mile. The pulley and tune will give you much better results.

Kreuzfeuer

Seems from what I've gleaned from the threads over the last few years, anything done to the C32 yields a (slightly) smaller improvement than if it were to be done on the SRT/SLK. Not sure if this is simply due to the weight, traction, or what...

The previous owner of my car ran a 13.1 bone-stock down to the paper filters in fall of 2010... same owner, same car with just the NW ran 12.7 in very similar conditions, 60' time was within .1s of stock run.

With three mods (intake, tune, pulley), I ran a 12.3 in muggy 82° Alabama springtime weather. So, she woke up well.

Lenin

Yes, that's a fact. C32s are slower than SLK/SRT with the M112K. It's the weight. And in the case of the air intake, it's the lack of space behind the grill that prevents C32s from using the air scoops or the original NW aluminum intake manis. Traction is fine.
As far as the numbers from the previous owner, some slips would help me to believe his story. What I know is that Rob NW stock ran 13.044 and with the NW intake 12.972. Not sure if it was a single or dual CAI but still, not that much faster. And I'm sure that Rob knows how to race. (even his wife know).

BTW, 12.3 is super good time with just your mods.

Ken311

I don't have any quantifiable data on power or 1/4 mile gains for the needswings intake on the C32 however, Rob @ Needswings has dyno tested the single intake on the SRT6 and made 30+ whp and wtq. After talking with him over e-mail, he has said the dual intake should make even more, in the 35whp range. Now I don't know how that would translate into 1/4 mile time differences with traction, as a few of you have touched on, but even 30whp is a BIG difference!

Take a look for yourself: Dyno

Regardless, I should be receiving the intake soon and am planning on hitting the dyno for a before and after.

Kreuzfeuer

I wish I had the PO's slips as well, it would be great to put with the rest of the papers I have on the car. I recall Steve (320_dreamer) struggling with the space issue behind the grille as well.

Thanks for the props on the time! I plan on running the 1/2 mile event in north Georgia this fall... curious to see what she'll do. I do happen to have my 12.3 slip; see attached.

*Steve was in the left lane, he was having some tuning issues that day. He's now running 11.9

link146

Great. Someone correctly responds to simple question. Thanks. When I asked if anyone had the data - I was not looking for someone to remind me that a pump, pulley and tune is the only way to go off the bat. Try to be responsive instead of a blowhard.

320 dreamer

any dyno can be made to show just about any gain you want. all the tech has to do is drop the weight of the car on a load bearing dyno and the # go up.
people find comfort in the dyno #. when i did my last tune the # were actually the lowest i had ever seen and showed virtually no gain in all the mods installed and the tune. yet at the track the et went down a solid .2.dyno # are just a tool like a wrench not the holy grail of power.
if you want to truly show the gains on the car go to the track and run the car. cool it down install the dual and run again

Lenin

If you got offended, I apologize. I interpreted your question as an interest to purchase this intake and install it on a stock car.

Ken311

considering the reputation Rob has with the SRT6 folks, I find your speculation highly unlikely. sure, anyone can fake dyno numbers but any company that does so long enough isn't going to remain in business very long let alone have happy customers praise their products on forums like these. it's much easier and more objective to compare with a dyno than a track test. on a dyno, you don't have to account for driver error.

that's exactly what i'll be doing
