come up to 1320 dyno day on the 25th. i just got evosport headers and will get my car tuned by LET for them. so it will be similar in mods to yours except my pulley is a 175mm evosport and my headers are evosport, i also have a 80mm tb and a heat exchanger. i am curious to see how my new numbers will compare to yours on same dyno and same day.
Yeah, we dyno'd there on Saturday. You guys are going to be there next Saturday?
Any interest in meeting at Cecil County this Friday? I will be leaving Wilmington about 4:30-4:45.

I also dynoed my car on that dyno before, but we dynoed in 3rd gear because we were told the dyno was a 150mph dyno. I saw your dyno was done in 4th gear that's why I asked.

Here is a close up pic of the inside diameter of the stock pipe. As you can clearly see IT IS NOT 2.75". I hope this clears everything up and proves that I am indeed right (its an ego thing).
For all those math guys out there adding .5" diameter to the pipe will increase the overall volume by 2.16". 4.91" to 7.07" and that's per pipe.
I think that helped bump our numbers up a little as well.

Anthony: Nice job on the upgrade selection
. Give me a call when you get a chance, I wanna talk to you about that thing we were discussing.
Kevin: Congrats on your new power upgrades.![thumbs](https://mbworld.org/forums/images/smilies/thumbsup.gif)
It was nice to meet you at Rob's shop a few Saturdays back.
Let me know when you decide to visit Englishtown, maybe I can tag along and see what my car can run.

It was really nice meeting you to! I could listen to you talk about the workings of these engines for hours!
I am hitting Cecil County Dragway this Friday, but its a ways from you. But you are more than welcome to come. We have a really great group of guys going.
Otherwise, we can certainly set up a day at Englishtown.

The intake tubes have my interest.
I'm curious to know if it's necessary to modify the radiator support for these tubes. I thought the reason for the taper on the stock setup was becasue of the small openings in the radiator support. They simply made the taper smoothly to get down to that diameter hole. I even looked at the SL tube upgrade that's soo populare for the drivers side and couldn't see how it would be of benefit since it still has to be heated to conform to the stock opening in the rad. support.

Hey there Jason,
We are leaving Wilmington about 4:45, so we will get there by about 5:30. The track opens at 5 and racing starts at 6. When I got there at 5:30 last time I was about the 10th car to run, and got a bunch of runs in before it got crowded. Then we hung out for a bit and were out by 7:30-8.
It would be great to meet up with you if you can make it.

The stock Driver's side starts at 3" and tapers down abruptly after the initial S-bend. THe Opening is then restricted to about 1.5". For our intake tubes the radiator supports do not need to be modified at all. The tubes are measured to butt up right up to the factory openings. You could potentially remove the stock openings and get 6" lengths of silicone to go through the opening and hook to the outer airflow inlets.

Also if you look at your stock tubes you will see exactly how a 3" tube will make a significant difference. If you have an E55 just pop the hood and look.

I went to atco last week, and I am going to work on my car sunday - do a thermostat upgrade. I will get retuned for the headers on Saturday teh 25th and go to teh track the following week.
I also dynoed my car on that dyno before, but we dynoed in 3rd gear because we were told the dyno was a 150mph dyno. I saw your dyno was done in 4th gear that's why I asked.

Is there any concern that the intake tubes are metallic and conduct heat more than plastic? Being that colder air into the engine is always the preference, is there a way to measure the inlet air temp of the flow coming through the aluminum tubing versus the plastic. The volume is obviously an advantage, but not at the cost of "colder air". No flames intended, just a question.

Aluminum dissipates heat at a very high and is the main reason it is used over steel for intake piping. After an hour or so of hard track time Aluminum tubing is often warm to the touch, not hot. I've seen this numerous times with intakes for all types of cars.

Here is your original post; the one that I said misrepresented the size of the stock exhaust pipes on an E55:
When someone refers to exhaust pipe size, or goes to buy exhaust pipe, they request the pipe size by stating the tubing's outside diameter. This is why you see stainless tubing offered for sale at various online exhaust dealers (e.g., Burns Stainless, SPD, etc.) in sizes such a 3.0", 2.75", 2.5" and so forth (and why you said your package used 3" piping). These are OUTSIDE diameters. So based on your post above, you stated the stock exhaust is 2.5" piping, which clearly implies OD, and which is wrong. You didn't originally say it is has 2.5" ID diameter piping (which is wrong, too). Then you post the following:
Now, and only now do you start talking about inside diameter of the pipe. In fact, your initial post listed the "3" exhaust your set-up uses. But, now we've shifted to inside diameter? Sorry, let's stick to your original statement comparing your 3" exhaust to the "factory 2.5" exhaust" (see first quote above, again) so we're comparing apples to apples. Nice try, though. ![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)
So now let's take a look at an E55 muffler and it's inlet pipe. First the muffler:
![](http://i513.photobucket.com/albums/t335/morbidcurosity/Exhaust/AMGmuffler.jpg)
The above photo shows a right rear muffler from an E55. The metric caliper is stabilized by the small bottle of water in the photo.
Now, here's a closer up picture showing a metric measuring caliper displaying the outer diameter of the exhaust tubing:
![](http://i513.photobucket.com/albums/t335/morbidcurosity/Exhaust/70mm_1.jpg)
Dang, 70mm!!!! Or expressed in inches: 70 / 25.4mm = 2.76"!!! So, thanks, but I will stand by original statement that the E55 has 2.75" (70mm) exhaust pipes on it.
Anyway, it's all good. Glad to see some other guys are working on making our cars better.

Kevin may post up more pics, but it is basically 2 3" aluminum pipes in place of the plastic inlet pipes. They are attached with silicone couplers. The tubes are Mandrel bent and maintain 3" diameter all the way through.
I'll post pics of all the pipes measured tomorrow.
As noted before, 40 RWHP+ and 65 RWTQ+. Some customers have also reported 10-15 more mpg and a more pleasant mood.
And intake tubes, filters, plugs and wires, and pump. These items are essential for good torque and keeping it in the higher RPMs. The exhaust is what put us over the previous record...
Kevin will be taking it there. If it doesn't put down numbers I like, he will be fired as head driver and we will have someone fill in. Kevin is unaware of this.

Come on 40 rwhp for intake tubes? Even if 15 rwhp is true I am buying them for $200. I would like to see a pic as they exit out into the front grill area. Do the filters remain in the stock location or do they attach at the very end near the radiator. I hope someone does a before/after dyno here.

You do realize that they thickness of the pipe wall makes a huge difference right? The factory pipe is about an 1/8" thicker around then standard T304 Stainless, we're not talking the cheap T409 that some people play off as the good stuff.
But if we are going by your measurments, then our pipe on the exhaust is actually about 3.25"!!! Damn, that makes us look even better. Thanks!
