Hello, I just wanted to introduce myself and my company. I am Joshua Lockwood and my company is Excelerate Performance. We specialize in performance parts for Japanese and European vehicles. If you need anything please let us know and check out parts available for the MDX at store.excelerateperformance.com

We have ROTORA rotors, UR crank pulleys, and more.

 

any chance that any products can be made for the 2nd gen and 1st gen MDX's since there isn't much?

 

What are you looking for? I'll have to see what I can come up with.

 

Lowering springs!

 

pullies
cats
intake
springs
spacers
exhaust

well anything to help with performance...

 

Would really love:

Mild Lowering Springs (Like H&R or Eibach)
Cold Air Intake (Like the CP-E)
Cat-Back Exhaust (Like ATLP for the RDX)

 

EXCELERATE

I know that this is an old thread but I'm despirately looking for a lowering solution for the 07+ MDX other than bagging it.

I dont undrestand why its so hard to find a way to drop this thing 2 inches or so.

The only options I've found so far is a custom bag setup which would completely and totally kill the ride. Or cutting the springs which I'm not willing to risk the safety of my family over.

I have e-mailed comptech a few times to see if they have anything in the works but haven't heard back.

If anyone else is interested and is having the same trouble, perhaps try contacting info@ct-engineering.com maybe all they need to know is that there is a market out there for it??

 

I don't think you're going to find a company to make springs for the MDX. It just isn't a vehicle that will be modded enough for a company to do all the R&D to make a spring. They will not recoup their costs.

 

I would buy a set it it would lower about 1.5" all the way around. Would be sooo nice.

Other suspension mods I am working on is finding a cross for the eibach front alignment bolt from the RDX...I will let you know if they work.

Also you can run the Sport stock rear sway bar (which is larger) to do away with some of the understeer.....alignment is definitley needed.

I think You know nothing about performance parts for MDX, while you introduce yourself in first post and when somebody asks what yoy have you answer with a question ?
I asked you several times in 3G TL forum and had no answer and we are both from CT
do not wanna judge You but IMHO - nothing special with your offer

 

Easy there guy! Josh knows his stuff. To be honest there is not much out there for the MDX's. Josh was simply asking what people were intersted in so that he can cross reference with other vehicles and possibly get a match with the MDX. Most mods would have to be one offs or modified for the MDX.

 

Huh? You've posted 3 times on this board in the last 12 months. What are you even talking about?

I guess in Europe they don't teach ppl what we say in America: If you don't have anything nice to say don't say anything at all.

I didn't make the assertion that I was an MDX specialist. I simply wrote that I can help ppl with parts.

 

play nice guys...

 

All I see on your website is a throttle body spacer. What is that supposed to do? Any news on anything in development? Would like an exhaust and cold air intake.

 

i would love a (1.5 gen) exhaust that sounds like an fx35

 

+1 and some lowering springs

 

For the MDX we have the TB spacer, UR crank pulley, ROTORA slotted or drilled/slotted rotors, brake lines,

 

Any particular mods that will help my MPG numbers ? LOL ... I know it might be too much to ask for the best of both worlds ....

 

Definitely don't get the TB spacer if you want to increase your fuel economy.. more air.. more fuel. Have you thought about putting the X on a diet ..

InAccurate on the 3G TL side has cut almost 1k lbs off the TL. Make sure the X isn't loaded up. Try to use a tire with a smaller footprint.. and keep it under 65 on the highway and you should be good. Make sure you keep the tires at an appropriate pressure.. but you know all that.

The UR Pulley might help by cutting weight and rotational force. I don't think anyone has done the numbers though.

 

The UR pulley is probably your best bet.

www.unorthodoxracing.com has some more info on the MPG gains.

 

I have not seen this mentioned anywhere so I thought I would ask. Removal of the third cat and replacement with a high flow cat/ test pipe / race pipe. Has anyone compared the OEM third car bolt patterns and length to that of the TL? Thank you for any help.

 

After looking into it further, the TL(04-06) and the MDX(04-06) share the same third cat respective to the MY. So you could use the test pipe or high flow cat in place of the OEM third cat. This will help to increase power as well as improve MPG. I hope to test this out soon.

Just an option for those interested in modding the MDX.

 

^Interesting

I'm still waiting for some sort of suspension so i can lower this bad boy.

 

Something else that will work on the MDX - the pre cat deletes and the Type-S cats from the TL. This will be sure to increase MPG and also give you a few more ponies to play with. I am going to try the deletes to see what kind of MPG increase I can get.

 

deletes & mpg increase.. the theory is sound.. but the application is a contradiction..

 

I did the high flow cats on my car (Acura TL) about a year after I got the car and saw a nice increase (10%) in fuel economy. I see 33-34 mpg on road trips it was 30-31 mpg prior to the cats. My daily driving mileage also went up. The cats are very restrictive from the factory, by increasing the flow on the exhaust side it relieves some of the back pressure allowing the engine to work more efficiently (i.e. better fuel economy). Add the light weight pulley into the mix (as I did with the TL) and you get some more gain. I saw 1 mpg just with the pulley. I have not take the TL on a long road trip since getting the pulley installed so I do not know what my overall highway mpg will be.

But heck, every little bit helps! The bad part is, when you do these parts, you also free up some horsepower, which you now want to play with! So it can negate the MPG gains. This is why I want to do some runs with the MDX under the same conditions at the same speed with each of the mods so I can see what the gain really is. Just have to wait on the deletes to become available.

 

yeah.. I removed my 3rd cat on my TL - stage 3.. although fuel efficiency did take a bit of a bump.. my foot got a little heavier

I'm not sure if I'll do any back end work on the MDX but interested in getting your guys review if you do mess with the 3rd cat & catback.

 

I'd take two sets of lowering springs

 

Ordered the Pulley and it should be here on Thursday. I want to say thank you to Josh (Excelerate). Once I get it in and the wife is home, I am going to do 4 runs without the pulley(2-55MPH and 2-65MPH for ~2 miles each) to get some base numbers of what the truck will get. Once I have that, I should be able to swap the pulley pretty quick and do 4 more runs matching the previous ones. I will post up my finding once I am done.

 

Got the pulley and was able to get it installed this weekend.

I did 2 runs each and these were 2.5 mile runs on the highway. One run was mostly a downhill (- grade less then 2%). The other was going back the same way but with the uphill grade. Each was done at 65MPH with the cruise. No rain, light wind and 80 degrees F.

First set- I did a run with everything OEM:
The down hill was 30.3 MPG
While the uphill was 24.6 MPG

Second set - Was done with just an OEM replacement K&N filter and no ECU reset. MPG went down just a little bit. Only thing I can conclude at this point is that the filter is allowing more air to flow and the ECU is seeing this, therefor dumping a bit more fuel. I do not have the tools to test actual fuel consumption. I believe that once the exhaust components are done, it will balance out.

The down hill run was 28.8.
While the uphill run was 23.9

Third set - after the pulley install and no ECU reset3
The down hill run was 28.8.
I have to think that since there is very little load on the engine while going down the grade, it remained the same.
While the uphill was at 26.9 MPG (This is a 8.885% increase at highway speed)


Even with the K&N it felt a bit more peppy. The pulley feels smooth and really allows the engine to rev more freely. Not as noticeable as it was on the TL, but still worth the $$$$.

My wife's average MPG is around 17.8 for her daily driving, so as she goes through the tank, I will check to see if that has increased. Now it is just a waiting game for the pre-cat deletes.

 

K&N filters aren't the best out there, some simple piping and a CAI filter would do a better job... I'll probably be making something like that for the MDX. Also how hard was the pulley install on the MDX? Also is the steering wheel harder to turn when the car is idling?

 

I could have made an CAI for it, but it is for the wife and didn't see the need for the noise that one makes. The K&N allows for more air flow and will support anything I really want to do. I make take the bottom of the box apart like I did with the TL to create an ICE box style intake.

The pulley was not all that difficult as long as you have the right parts. The Honda crank pulley tool, 2 - 1/2" breaker bars and a good 19mm socket. Sorry, for got to mention a 14mm for taking the belt off. In all it took me about 45 mins to do the install.

I did the stock size pulley, so there is no lose in power steering. Jason

 

Sorry for the noob question, but what does a pulley do exactly? Was the MDX one easly to install? Will it cause any warranty issues?

 

black05TL, I've seen a couple of members post about removing the lower part of their intake down. What does this consist of and what are the benefits? From what I understand you remove the short rubber tube under the box and everything below.

 

The pulley is a light weight version of the OEM one. The stock pulley weighs roughly 7.8lbs if I remember right. The UR pulley weighs ~15oz. The reduced weight reduces the amount of parasitic loss caused by a 7.8lb rotating mass. The install is not hard if you have the correct tools to work on it.

Warranty issues will always be up to the dealer. If you had one on the car and you went in for your door switch not working, then it will not void the warranty, but if you went in with a blown head on the engine, they would investigate and determine what it was. They will a lot of the time blame any aftermarket part for the issue. This is not the route cause but the do not want to accept liability for the issue with any aftermarket parts on the car. Some dealers do not care and will not give any grief about it, as some will actually install the parts for you.

I did a similar thing on the TL before I got the CAI. It is essentially the same as installing a CAI. If you have a K&N and removed the bottom half of the intake, you will see #'s similar to having a CAI. I did a dyno before and after with my car and the #'s were close.

You are allowing the truck to pull colder, denser air from behind the bumper rather then air from under the hood. I have not looked at the one on the MDX, but the thought had crossed my mind for doing this. You will pick up a little bit of intake noise. The bottom half is used to tune the noise signal so it is not audible in the cab of the truck. If you look at the tube that runs from the air filter box to the throttle body, you will see other parts that are used for tuning this signal as well.

Hope this helps.


As for results. After a tank of gas in the truck and the ECM has learned about the extra air, my wife was able to go from the before mentioned 17.8MPG up to 19MPG without changing any driving habits. Not a huge gain, but it is a gain.

I am still awaiting the cat deletes and will order those as soon as they are available.

 

what would be the best intake for a 2002 mdx?
