Whats up boys,

Had a chance to get a baseline on the car! Finally went out to the dyno to see what kind of power (if any) my bolt ons were making.

Granted there's not much real world info on some of these parts, I wanted to see for myself if they made some power.

Background stats:
2010 C63 - Non P31 / STOCK Tune
Eisenmann Race Exhaust + Secondary cat Delete
Renntech V1 Intake + AFE Pro Dry Filters
Dyno Dynamics Dyno
Both Runs made in 4th gear (wanted to do a 5th gear pull, but I was already near the speed limiter on the 4th gear runs.

HP - 419 RWHP
TQ - 395 LBFT TQ
Dyno Chart Attached

Figured about 18% drive train loss. Thats right around 500 HP at the crank and 466 LBFT TQ.

I figured the secondary cat delete made up for a great deal of the gains, but I'm convinced the Intake / Eisenmann setup make a few ponies as well.

Pretty happy with the run, was actually quite surprised.

your car looks great mate

Overrated

Clean car Kriston. Good #'s on the stock tune as well.

AMG893

Great looking car!

Petakii63

Strong car with no tune!

Kriston

Fellas, some more interesting facts.


From my experience, the Dyno Dynamics machines read on average 10-12% lower then the Dyno-Jet dyno's (which most would consider a standard in Dyno Machines here in N. America)


If thats the case, This car may actually be making more power then what I dyno'd at this past weekend. Im curious to get the car out to a Dynojet to see what it puts down on it.


Either way, after reaeding through some posts, it seems most members are putting down similar power, after they tune the car. I cant wait to see what it does after my Tune.

yeah see 400whp "stock-ish" isn't unrealistic...everyone thought i was crazy when my car dyno'd 413whp with 2nd cat delete and stock file...car looks great by the way

Wow kristo, that is one strong car without a tune. I got right around the same power with a tune. I cant wait to see the tune go on, this car will be a beast. With headers this would be a rocket

OlegKouz

Great numbers, I am going to be doing some before/after custom ECU tune dyno numbers here on a dynojet soon, will also post a video!

Kriston

Thanks so much guys,
I was very happy with the outcome granted I'm running the stock tune. With Headers + Tune would you all say 500 Wheel is attainable?

Petakii63

In your cars case 500+

shades

Yeah you will hit that no problem. When you get the tune, you should see approximately 460+. That's a very strong car you got bro. We should do a couple of fun runs before you get the tune on. That will tell us where your at real world. I got the tune so that could be fun bro

RuckinAMG

Very nice, congrats!

abcut973

Good stuff man
Lol your car almost ran away in the first vid. Were you inside or outside when it happens? My heart would have dropped if the guys didn't secure the car properly

Kriston

The Tech was driving the car, i was outside.

As soon as i started to see it go sideways on the dyno i stepped forward to let him know.

They used 2 straps to hold it down initially but, it needed 4.

Out of curiosity, to those who may know. How can I access my diagnostics mode on the car? I noticed the tech put it in diagnostics mode in order to get an accurate reading on the car.

CMC-63

Car sounds pretty good! Didn't you have a resonator delete too.

And ditto on the first vid, that would've take a few years off my life!

Kriston

Hey there,

I have an eisenmann race exhaust, which deletes the resonator. I have also removed the secondary cats as well.

Note worthy is the car does not sound like this with the stock air boxes. I swapped my renntech intake out for the stock boxes and immediately noticed a less throatier exhaust tone.

Needless to say the renntech box is back on the car.

Autosport7

Awesome numbers bro!
Looks like secondary car delete may be my next HP mod following a pulley.

I think you mean Dynomom. Test. You can get to it in the same menu as the Service Reset. The PFD below will get you there.
