Here are the results from testing and tuning of my C63 AMG.
The car had just over 2000 miles on the clock for the first dyno session. Prior to dynoing, the car has had custom tri-Y long-tube headers and full exhaust fitted and made by Gintani (now off the car to finish production jigs).
The car was also previously run at Famoso Raceway, running: header back cat-less Gintani X-pipe with Gintani Full exhaust & Mufflers + OE Tune + Sunoco 104 gas + Continental Sport stock street tires. 1/4mile - 11.608 @ 121.93
Stock headers and exhaust were re-fitted and the ecu flashed back to factory stock, adaptions were cleared with SDS. The car was then driven for 2 days (approx.70 miles) to re-adapt to the stock tune prior to dyno testing and tuning. For the dyno the car was put into dyno mode and tire pressures checked. The front engine cover removed and hood open during each run. Gasoline used: a full tank from empty of Chevron CA91 Premium.

The first test was to record a baseline pull of absolutely “factory stock” vs. removal of charcoal filters and addition of K&N air filters. The results were surprisingly good, with an additional +10wHp seen (dynograph attached). The factory stock run is green and the run with K&N filters is red.

The second test was to run the car "as is" with K&N filters and charcoals filters removed vs. “Off-the-shelf” ecu tune. +54wHp peak-to-peak gain was seen on top of figures already recorded (attached). The factory stock run is green, the run with K&N filters is red and the tuned run is purple. A video of this session can be seen on YouTube: http://www.youtube.com/user/OEtuning...12/z7EQbsgcyw0

The third test was to modify the inside of the stock USDM airbox Ala R.O.W. airbox. (Pictures attached) Gains in low-end Torque were seen on the dyno, peak numbers remaining constant with no further tuning. This run is depicted in Pink on the 3rd dynograph. (Big thanks to Bruce at TTM on Long Island, NY, who has long been doing this mod for many satisfied customers.)

Thanks Jeremy for showing once again that K/N's do work. Although the ney sayers here will find some to deny this yet again.

Oh yeah, nice numbers on the tune as well

propain

Keep up the good work Jeremy. Nice to see the gains from the K&N's and removing the charcoal.

Cant wait for you know who to come in and ask how many CELS you are throwing.



I would have loved to see Gintani on the 1/4 with DR's and skinnys up front before you did this though...

SALES@OETUNING

To my suprise I was not expecting a 10+Hp gain to the wheels with removal of filters and K&N. I did re-run the car over and over to confirm these results. No CEL's BTW .
I will have results from exhaust and headers dynoing on Monday. Stay tuned for the numbers.

Sincity

Yes and no. There have been prior tests by Vadim showing gains with removal of charcoals with stock paper element. There was also a prior test a little more than a year ago that K&Ns only show a 5 hp gain. This confirms that both charcoals and K&Ns work so the 10 whp is not attributed to the K&Ns by themselves.

What would be interesting is a test between TTM's box top intake tube mod vs. a "ROW" box. If the gains are the same, this will confirm that a "ROW" box top is not needed.

What is most interesting is that you are pushing 425 WHP on a Dyno Dynamics.

Jeremy: Thanks for the comprehensive testing. Can't wait to see another header option on the market.

bluejae

is there a thread on this mod to the stock air box? is this a DIY mod, or having TTM do it is better?

BenzoBoi

Good stuff J!

Hey Sin:

I know what you are saying my friend, but I am only trying to point out that for the hundredth time K/N's work.

Many on this site say to them, and I do agree that some of the gain was probably do to the charcoal removal.

Bottom line is I am a K/N fan, and this is yet another thread that shows CONCRETE evidence that they work.

Sincity

I have them on every one of my cars. Incl my lowly 190e 2.3.

_AMG_

Wow those are great gains!!! Awesome work Jeremy.
Cant wait to see what kind of numbers its gonna put down with the whole Gintani setup.

Unbreakable1

when GTPRO dyno'd my car originally, just removing charcoal filters, we showed btwn 8-10 rwhp gain also - no change in filters themselves

im not trying to say k&n don't work, im juss sayn what i saw

I agree. Over the years, I've seen dynos on the E55 platform with and without K&N filters; some dynos showed 2 whp gains while others showed 5 whp gains. And although the gains were minor, they were gains nonetheless. I believe those gains would be greater if they could be somehow measured on the track since it is often hard to simulate 120 mph winds on the dyno.

mthis

Some STRONG numbers you got there
Keep up the good work.

hhughes1

I agree. I think any mod on the intake side will make more power on the road(or track) than what will be seen sitting still on a dyno.

propain

+1

On the top end for sure.

Jons95c36amg

Jeremy is the tune the same file as mine?

Sincity

No. Yours was tuned to be slower than Propain's. J/K! J/K!

I am Jeff

LOLZ

GHAZAN

GO REGGIE!

propain

That extra HP shows up top. (see sig)


Maybe NOW he will get the K&N's and the airbox mod. Somehow I doubt it though. No matter how many people tell him and show him...... Well you know.

ZephyrAMG

The plaque for the alternates is down in the ladies room.

all8up

I wish someone could do a similar test for our cars since we have paper, foam, and fiber available for our cars....

Solid gains by OE nonetheless and thanks for showing us the results. I'm really curious what type of gains they will see with the various exhaust components.

Jons95c36amg

I justed wanted to know since I went with the charcoal delete the CEL came on. Now I have no problems. Propain-lets not get this started again.

andy_c63

Which filters are better oily K&Ns or foam Carbonio?

cls55

i have both , go with k&n the carbonio is too soft, does not seat well.
