View Full Version : Riddle me this ???

It's that lovely time of year up North again. The snow has finally stopped, so I ventured out to the parts shed and grabbed my JLT intake. I cleaned and oiled the filter element and waited for the red to creep in.

I disconnected the battery, removed the OEM intake, cleaned the MAF sensor and wiped all the winter grime away.

Re-installed the JLT and, just as before, I get this weired bog.

This be my riddle:

With OEM intake, tires broke loose all the time from a standing start.
I put on The JLT intake, and I get no tire spin and it seems to take way long for the engine to build up.

No doubt it makes lots of noise, which is all well and good, but why is everyone else getting such great results/experience, and I don't? It has been on for a week, with 350 miles of use thus far.

Yes, everything is pluged in correctly. Yes, the orientation of the MAF sensor is correct. Yes, I have a tune, 4.10 gears and Steeda pullies.

I really want the extra 10 to 15 HP from this, but it has been eluding me since I got it.

I have heard some really great improvements out there, and wonder why I don't experience them.

Any answers to this riddle? (Not sure weather I should duck or jump)

My Kooks Headers are coming soon, and then I can get this Biotch set up on a Dyno maybe.

Update the Tune.

I know you've gone through just about everything trying to eliminate the "bog", you are right maybe a dyno tune with the Kooks will yield some good results.

Have you thought about this possibility though...perhaps there IS no bog.

Perhaps the car is performing as it always did in most of the RPM band (where you feel the bog) and when you feel the power come on it's just really waking up the powerband?

If I recall when I was NA and installed mine I didn't notice the oomph all that much compared the sound, but it DID make a difference in the higher RPM ranges.

I know beyond SOTP feelings you do have the data of tire chirping before and after too, so I know this may not explain everything, or be the answer, just a thought.

Honestly until you get the raw data, i.e. a before and after dyno to show the two power bands, you may never turly know what is up or if what you feel is normal and just your interpretation of what everyone else feels...

fro a dead stop my K&N has the same bog, and my brothers whos has the stock box doesnt really. but at higher rpms i cna feel the car kick in and pull.... build up the revs before you go lol, even from that red light

Clean the MAF.
The filters are full of oil when new.
Mine developed a bog - cleared right up after cleaning.
The re-tune from PSP has it ripping now!!!

Remember, the intake on this car was massaged by Roush and is one of the most free-flowing of any Ford to date.

The stock MM airbox is considered an upgrade to the CVN boys...

Try cleaning your MAF...newly oiled filters are famous for depositing "new" oil the your MAF...

Oiled filters are a PITA w/ mafs and I won't use them.

Some people may have missread his original post...he did clean everything...am I right? And all this happened AFTER he cleaned. He wanted to know why. I can't answer this, and no one here has yet.

As far as dyno results on a CAI. I did a pre-CAI dyno run, and a post-CAI dyno run immediately after the CAI install. I did 3 pulls, with a max of 9RWHP gain, and a min of 7RWHP gain.

I have the K&N, and I've never had a bog.

How about a poem instead of a riddle:

Is there a plastic cover,
that needs to be removed?
If it isn't then the other,
will bog it down and it won't be moved.
This other could be wax
or oil once removed for Max
Performance can be seen
if you but learn to ween
for perhaps he needs to learn better how to clean

???

I have no idea.

mpearce...He said he cleaned the MAF BEFORE putting on the "newly oiled" filter...Therefore, my assertion is that the "newly oiled" filter deposited "new" oil on a previously clean MAF...Hence the bog...

+1 even if you are careful about oiling there is still a little extra left to get on the maf if you lay into it. Try cleaning the maf again after a few days. Also what are you cleaning the maf with?

The horse power gain is at about 5000 rpm's, at low end probably next to nothing.

That seems to make sense.

Maybe my MAF Sensor can't take any more air. Do any after market sensors have a greater capacity.

But I'll go home and clean my MAF sensor AGAIN with the can of CRC MAF Sensor cleaner I have been using.

Just out of curiosity, what is the CFM range we cover stock?

You MAF should not be overtaxed while N/A.

Joe, I think its you air/fuel mix. A dyno tune will help as will the headers. I'd wait to see what she does once the headers are installed. More in = more out.

I just feel like such a fairy. Makes lots of noise, but can't even do a friggin' burnout.

Might as well put a "fart can" on it and call it a day....

I dont understand the whole retune idea. I've talked to DR, Lidio and Darrin and not one of them says a car has to be tuned for a CAI.

Why not take the CAI off, drive it for a week or two and see if it still bogs down. Then you know what isn't the problem.

Unfortunately, I have done that about 20 times over the years. Seems My Marauder just doesn't like the extra air, at the low end. (Qualifying Statement there)

I indeed was told no re-tune was needed. Was just wondering what I might be missing.

I did like the Poem though.

Thanks for the clarification Local Boy. This HAOLE wasn't paying attention.

All you "MAF cleaners" and "filter oilers" always have issues! :D

My car is a garage queen and only has 11,000 miles. I guess thats why I've never had any problems.

Maybe it doesn't HAVE to, but it certianly couldn't hurt?? I had a re-tune when I had my CAI done. In fact, IIRC, I've had retunes after every mod that I've ever had done, just for my own peace of mind. That's probably another issue as to why I've never had a problem? :dunno:

Last night, I disconnected the Battery, pulled the MAF Sensor, cleaned it, waited ten minutes. Then re-hooked the battery and went off.

WOW! ------ No difference at all.

On a good note, my Kooks came. May all the extra air in can't get out. At least that's what the car feels and sounds like.

When you have your exhaust done...get a fresh dyno tune?

Should solve your problems.

You guys near tuning places are lucky. For me to get dynoed means a day off, a long drive and $300. So I've never had it done.

Yes. I feel your pain.... A local shop said they could dyno tune my Marauder, but had to send the data to someone in MI to write the tune.????

I'll just go see Lidio when the time comes.....
