It should be quite comperable; if not better, to the other systems since it eliminates almost all of the restrictions and is still grabbing true cold air.

 

i think this is where i'll be also , after george bush free money program come's in.

LET - SL 55 setup

 

I'm finally going to get my car dyno'ed on May 6th, I have the SL55 "Y" & hose's on my car. I wonder if NeedsWings would send me one of his intake tubes to do 1 of the 3 runs with it, just to see how much difference there is between the two.

 

Code3 has an intake mod for less than 100 bucks that's been dyno tested with his pulley it gained almost 20 hp. I'd check it out first before changing to the sl55 intake.

 

Look at the SL55 fact, fiction or myth link. It has the numbers for, BDJ, NW and SL55 intakes.

They all look about the same to me. My G-tech meter will give you HP in a 1/4 mile run. I had ran 4 or 5 runs all at around 12.7, I went and had the resonator removed & installed the SL55 "Y" & hose's. I did not do any runs between the resonator & "Y" mod's, but I dropped to a 12.3 and the G-tech meter showed a 27 HP increase compared to before the two mod's mentioned. That's at the wheels and the wind hitting the front of the car. All of my runs that I have done with the G-tech meter the launch was the same, TC off-small burn out, TC back on and floor it. That type of launch sure does make a bad 60' time, but you are alway's comparing apples to apples that way.

 

Is the LET setup just all of the factory parts from the SL55 to do the conversion or is there something extra supplied as well to do the installation?

 

It's all MB parts - you need to do a few slight modifications to make it fit.

I provided the MB part numbers on the first post of this thread - shop around for prices - for me LET was the lowest cost.

 

the sl 55 amg dcai means is a sl 55 original spare part? not aftermarket? has the same performance of needswings? thanks

 

the sl55 intake is just that, the factory intake on the sl55's. we flow bench tested all of them, the sl55 intake does flow more than the srt6 factory intake but less than our single CAI

 

from here.....although I'm not sure where the SL55 boxes have been tested to 15"WG, if anyone has a loink - much appreciated.

the main restriction on the V6 is the Y-pipe. If you study it closely it nips down quite markedly at that point.
The NW CAI, DCAI and SL55's all have larger Y-pieces.

Based on my engine model....the CAI should give a stock motor
- a 74/155 at redline = +4 to 6rwhp for the CAI and +6 to 8rwhp for the DCAI = very noticeable.
Many have reported better bottom end delivery and throttle response as well.

But if you are going for a pullied setup, the gains are more because the air flow is much more (730 v 580cfm at WOT /w stock air boxes)
- a 62/155 at redline = +7 to 9rwhp for the CAI and +9 to 11rwph for the DCAI = nothing to be sneezed at.

While you're at it Blueyes .....if you want to keep yourself busy....
Try looking around at the 82mm Trottle body and SC intake mods PN 2731410325, or 80mm (easier) PN 1131400104 or PN 1371410125.
Which will give you another 4-6rwph by opening up the throttle gallery and supercharger inlet at the 730cfm levels (62/155 setup)
The Y-piece fits onto the TB, so should be sized accordingly with your intake/filter system, there are many out there.
One thing always leads to another....
All the info is either here or over at mbworld on the C32 and SL55 forums.

Word of caution - If you are going 62mm pulley route instead of the 65mm with the intake upgrade, after the intakes - do the fuel upgrades and get an AFR gauge before the pulley otherwise there is a heightened risk of going way lean (reportedly) and frying your motor.
decision process would go something like......
65mm....happy?>No...DCAI...happy?>No....Tune....ha ppy?>No.....Supercooler, Water Pump, Fuel Pump, Lambda and Logger setup (or at least AFR gauge)>Check!....62mm+ Tune....happy?>No....save more money....;>)...stay tuned for our next episode folks....
happy?>yes...enjoy!

 

All I can say is that years and years later - this is the best performance mod I made.

That is to say - just about any intake mod you do will provide great results.

Second best mod you will make is a pulley - once you give your SC 3.2L more breath... it's time to "force feed" a little more air. And I have my favorite pulley as well...

Third... get a decent tune......

I enjoyed modifying my SRT6 - what?? - going on six years ago now!!

With the exception of the idler pulley failure - I've never had problem one. The SRT6 always passes California smog. I still have both Cats - (but they are hot swappable) I still have the OEM muffler.

That's six years of instant throttle response on the freeway during my 35 mile M-F commute .... and tons of fun in the canyons....

And posting the fastest times ever recorded with a SRT6.. Period...

And my favorite part...

All the mods totaled under $2K....... enjoyed being the first owner to venture out and install each one of these mods.. and enjoyed sharing it with you all...

The SRT6 never grows old with me..... nor will this forum or the members...

 

Literally

Step 1 - put on gloves

 

so basically you're saying that installing only the DCAI that both sl 55 amg or needswings, the power increase is minimal if you do not also mounts the pulley, you suggest to 64.7 mm?

 

installing the sl55 or needswings willmake abig differance in performance. adding the pulley latter on also makes great power.

 

Just wanted to check a couple of things...

1) Does the part number
113 090 01 29
Fit directly onto our stock Throttle body?

I found a
113 094 01 03
and this web site says it fits SL55 AMG 2003-2006
AIR DISTRIBUTOR | Genuine Mercedes-Benz | 113-094-01-03
maybe same part - different car????


2) Can you change the Y-pipe for the SL55 and still use the stock air hoses/filter boxes...?
I'd imagine its a different inlet dia.
Maybe I'd need a pair of silicone reducers.

Thinking of doing a staged install to evaluate improvement.
(seem to recall people only changing the Y-pipe??).

 

The way I've read it, goes as follows:

82mm Y Pipe - Part #: A 113 090 03 29
82mm Throttle Body - Part #: A 273 141 03 25
Throttle Body Gasket -Part #: A 113 141 07 80
SC Inlet Gasket - Part #: A 137 141 07 80

 

looks like one might be broken off.

Anyways - will this click fit straight onto our stock TB?
But...my old hoses wont obviously fit - I'd have to get some matching silicone pipes if I wanted to use the old boxes. Or make the ones shown fit.

 

How I installed mine... clicked right on. No tools needed.

Nice....
stock SRT6 TB?

other - 4" dia pods with 3" IN/OUT?
