Finally got rid of the last remnants of the early 90's coil hose.
Tried a couple of things with stainless steel but settled on polished aluminum tubing with silicone hump hoses and elbows.







Looks more contemporary, and with the filter change and straighter air flows it performs even better !!

Body mods going out to the painter next week...Wald EX replica front spoiler, bumper inserts, grille shell, grille insert, mirror covers, late model trunk filler, wiper blanks...

When they come back I'll install along with Euro headlights

very nice

Question, if you use narrower pipes(ie: coupled from 3.0" to 2.5") would it make a difference in the CFM's(higher or lower)?

I'm guessing it will increas the PSI's. Why are most TT system made with such large piping systems. It almost seems like it's a tight fit is such a limited amount of space in any W124.

BTW, it looks great? Got any photos of your intercooler?

Thoughts on performance improvements?

myfirstbenz

wow, looks way better. My first thoughts with the original hoses were that you sometimes have to give up looks for performance, but now you get both

A+ for effort and presentation!

Bigpete123

wow, man. you're really going to town on your car!

I have to say, I'm glad you're doing the trunk filler panel (it will look much better than the reflector thing you have on there now! )

Its goes back to the engineering stand point lets say you have a 1 liter piper going to a 1 liter engine(just lamen speak) at 10 psi entering, it would be 10 psi in the engine. Now we have a same opening for a 1 liter pipe but it then goes down to 1/2 liter pipe and then into a 1 liter engine, even though the pipe is smaller it would still be the same pressure entering the engine because the amount of space.(hard to describe without diagrams, now you ask why dont they make the output pipe smaller on a turbo, well it would increase psi but would max out very low. By the way the Turbo system looks real sick......Extra sick after the new piping. Now what would be cool is if you could inject liquid nitrogen into a double piped heat exchanger to truely make cold air induction. I think it would cost a lot but it would help with cooling the air. Any thoughts?

Haven't done a performance run to see if the intake mod is producing more power.

What I have noticed (after checking for leaks and retightening clamps) is that letting off the throttle at low RPM now produces a noise ( wierd chirp ) which I am concluding is that the improved intake airflow has produced better boost levels at low RPM and the noise (hopefully) is bleed off from the boost pressure against the closed throttle plate.

Your nitrogen idea is interesting !!!

Many years ago in a place far, far away those reflectors were the hot mod

Times do change....

I would have to get the car up on a lift....

The intercooler is mounted on the passenger side chassis rail parallel to the engine and under the turbos.

Good position for airflow

Ahh, I was trying to figure out how the piping went. I think if you sent liquid nitrogen in and had the system pressurized I believe it would stay cool for awhile. like say fill a canister and then have like a tire valve to pressurize the system.

By the way I'm a Chemical Engineer too. But not sure what kind of gains you can get. Also that chirp might be cause by the air moving through the pipe from when its going from laminar flow to turbulent flow or reverse( almost like a sonic boom.....If its that then your crazy fast)

It's a low RPM "chirp" or "hoot"....have to figure where it's coming from as the pressure/boost piping doesn't include a blow off valve.

Was able to find enough enough road to do a few 0-60 runs.

The intake piping change added to the previously changed K&N filter and pressure/boost piping was incredible !!!

Using the G-TECH Accelerometer I was able to pick up about 3/10 running 5.46 and 5.57 0-60 times.
Looking at normally aspirated AMG 5.5L V8 fast and closing in on C32 Kompressor numbers.

Launching as I did prior to the intake change resulted in first gear fishtailing and continuing a bit shifting into second.

It increased HP by 11 and torque by 18 which is significant.
Best launch now is gear shift in lowest gear, hold brakes then floor it....produces the least wheelspin and so far the fastest 0-60 times.

Comes down now to learning the vehicle and improving the launch technique.
I believe I can pull another few tenths which should result in consistent 5.2-5.3 0-60 times !!!!

Never, ever expected this......
