Keep in mind that the carbonio foam filters are known for being over saturated with oil. You may have to clean the MAFs again after installing. Just fyi.

Even Money

Thanks..that's what I've been told..

James@ACG

If you ask Wayne, he'll let you know that a few months ago he ordered a euro air box that was used, and had a bad or dirty maf, once he put the maf's that he had from his factory airbox his power was back up.

i'd try the dyno run honestly with the stock paper filters, unless you got the new carbonio filters which are now oil-less filters.

Keep me in the loop Will.

James@ACG

superlubricity

Yep. I think I called James at least 3 times within one hour.

Once I put the original MAFs back in my consistent power curves were back.

Also worth noting that avengerboater and I have tried various filters and none made any more or less power on the dyno. Avenger still runs paper filters because of this.

Even Money

Will keep you advised James, and thanks for all the help. Copy on the filters, but I thought it was worth a shot...maybe my stock filter's bad. These carbonio foam filters, I think they are the oiled ones, seem to be made by pipercross(although they wouldn't confirm that on the phone). They had a really good rep, so what the hell??

We'll know Sat. about 0945!!

Now all I need is a deal on some ADV wheels...

avengerboater

Yup. At least we weren't able to see any gains on the dyno with the k&n and carbonio filters compared to stock filters. Now, will there be any noticeable improvements on the streets or drags with 100+mph wind...who knows?

Even Money - It seems fairly common from others on this forum but I'm just wondering why did you get a Kleeman Tune knowing that you were waiting on MHP Headers? Am I missing something??????

You obviously think that the MHP TLH's are better than others so why not go with the tune as well?

BTW - Cory told me the same thing he told you after I originally got my tune from them however the dyno results (delta's) don't lie. My delta with Kleeman

Is your 1/4 mile time stock or was that with the Kleeman tune?

Even Money

^I got the K1 tune back in February, long before I thought I was getting the LTs. I'm going to try the K2 file, and may eventually get the MHP v3. The 1/4 mile was with the K1 tune, 406 whp on the local dynojet. I don't have a delta as I started with a mustang dyno that has since broken. So, I only have the after. But, based on what others with the same tune are getting on the same dyno, I'm about 15 whp short....so hence cleaning the MAF and trying the foam filters...If after getting the LTs and w/ the K2 file..if still not happy, then I'll try the MHP v3.

Sincity

^ I don have a baseline either. But you do seem about 15 WHP short. I did 421/384 with 70 degree temps and 9% humidity. Those numbers are with ROW box tops and K&Ns (if that made difference).

superlubricity

Like EM mentioned, two other cars on the exact same dyno with the same Kleemann tune dyno'd between 422 RWHP and 426 RWHP.

Not a huge variance but enough that we've been scratching our heads. We've had six different C63s on this dynojet (A MHP-tuned car, a evosport-tuned car, three Kleemann-tuned cars and one P31 car). All of these cars came in as expected except for EM's car.

Sincity

Perhaps it has something to do with break-in? Cory told me to hammer (not my intention to start a break-in debate) the car from the day I got it.

Even Money

I didn't baby it during brea in. Varied rpms w wot every so often.

superlubricity

avenger and I put that to the test. I babied my car, he beat on his during break-in. Our peak HP difference was less than 1%. Myth debunked.

Carbonio foam filter, $80 each, just arrived. These are their new design, NOT oiled. As you can see, there are three layers of foam. The guy on the phone said they switched to dry foam due to customer feedback/complaints about oiled MAFs, etc. He said they work just as well. So, we'll see tomorrow am! You can get these from carbonio direct. Shipping is free, unless you want it faster.

Sincity

To clean, do you just soak it in a solution of Simple Green?

Even Money

I think just soap and water...then dry.

Hans Delbruck

edit: never mind, he has P31!

Wonder if there is any more dyno data about losing HP with the charcoals removed.....

cek

Either way, the actual results with charcoals removed on my P31 car were:

-4.79 (-1%) RWHP / -2.33 (0%) RWTQ (using average across 3 runs)

Given the number of variables involved with doing dyno stuff +/-1% gain/loss is noise. Arguing, based on my numbers, that charcoals make a difference one way or another is without merit.

cek

I babied my P31 and it's clearly pulling VERY healthily. Further debunking the myth.

superlubricity

Agree 100%.

You are also only using peak #'s too. In looking at your graphs without charcoals, you didn't have that same little spike at 6700-6900 RPM that you had when the charcoals were in place. There were even some places in the mid range that you made more power without charcoals.

Fun stuff.

GHAZAN

New dyno today? I'm going to guess <6rwhp difference, no significant change.

Even Money

On my iPhone. Will post graph later. Bottom line, nothing changed!! Must be the ecu, don't know what else it would be....if there was an issue. You'll be able to see from the graph that the ecu appears to pull timing a bit at 4100 and 4500 rpm, also the plot is jumpy compared to others I've seen on same dyno,tune. If not for the anomaly at 4100 rpm the curve should trace to about 420 whp, vice the 405 I got. Did 5runs all very close together. Same type fuel Afr was low 12s. I would try a reflash at this point, were I not getting LTs and anew tune in about three weeks. So after the header install hopefully the new kleeman tune will fix things.

Oh, and I know how toclean the mafs now.

superlubricity

The other explanation (and I hate to say this) is your car may simply not be as strong as others. You could be chasing a ghost.
