You have put a great deal of engineering and thought into these intakes. As far as cost even the V4 is well within reason for what you are getting. In my 45 years of modifying every imaginable kind of vehicle I have spent a lot more money for a lot less intake. Looks great and has been added to my list of items to get. When will they begin shipping?

Greg,

The Hp /Torque numbers you show for the air box mods are on a stock engine correct? Also are the euro+drive lite HP/Torque numbers with a stock car...no modified exhaust or airbox? Do you have numbers of the euro+drive lite with the V4 air box? Correct any of the above statements if I am incorrect and thanks for all the information.

Hi Clay,

All the power numbers are on a stock engine. That means STOCK, no exhaust mods, no Euro+Drive Lite. The V1 results are with the stock filter. The Euro+Drive Lite results are with the stock intake system, no other mods. All of the intake numbers we measured on the same day within a two hour period so conditions stayed constant. Same with the Euro+Drive Lite numbers.

At this time we do not have combined results. In other words we don't have Euro+Drive Lite combined with intake numbers.

Greg
That is what I thought...numbers for the euro-dive lite with the V4 air box could be even more impressive.;) Throw in a muffler delete and they may be even better. Thanks.

V4 Ordered

EDL with a V4 and improved exhaust should be awesome. However to avoid confusion we are posting power numbers for individual modifications. On my personal car, I plan to run the EDL "Race" tune and a red V4. We did that in testing and it was very strong, especially at the high end.

In testing we ran the V2 intake with the EDL "Dynamic" tune quite a bit. That's a pretty fun combo too.

Greg
Just ordered the V4 in black. Thanks for all the info Greg.;)

Thanks for ordering, you are the very first!

Greg
Here are some pics of the first V4 install. First pic is what you remove from the car. Once I got it sorted out with Greg it was no big deal to install. First impressions are the fit and finish are excellent. Getting ready to go for a drive . I will follow up shortly.

Thanks! That's the first Black V4 ever on a 124! I think it looks great.



The only anomaly I see is that you have the ram-air tube shoved pretty far onto the factor's fresh air duct. It will line up a little more nicely if it's not on quite that far. No big deal though, it will work fine either way. I'll post pictures of that in the instructions soon.

Greg
Thanks Greg...I thought it was up a little farther than what you said but it seemed to like it there so I left it so I could get out and drive it. I'll pull it back to match the instructions when you get them up.

First drive impressions...

Turbo seems to spool up a little quicker as the power comes on a little stronger. Throttle response seems to be better also. Seat of the pants HP/Torque of 10 or less are always hard to tell but I would say it is there. Important for me is spool up and throttle response plus the cooler charge air meaning you loose less Hp/Torque when it gets hot and the computer starts to pull fuel/timing/boost to protect the engine from detonation. A winner all around.

As far as sound...

I do hear the turbo now when you could not before. You get the typical whine/whistle when the turbo really starts to wind it up. Mostly in the upper rpms. I like it...now I know its not a normally aspirated engine. Not too loud just enough to let you know its there. If you don't like that kind of sound I would go with the V1 and keep the stock air box as it does a fine job of muffling the sound.

Now I can't wait to get the euro-drive lite...should be here tomorrow:).

Given that the turbo has an intercooler and a waste gate, I'm wondering if it actually does matter.

In most cases, the turbo has plenty of spin to get the air to the proper pressure and temperature. Higher inlet temperature means it has to pump in a bit more air, but it should have the headroom to do that. Whenever the waste gate is open, I wouldn't think the inlet temperature is going to make any significant difference.

I guess at lower RPM where the turbo is still spinning up, a lower inlet T could help a bit, but I doubt anyone could actually tell the difference.

Maybe I'm missing something about the way turbos operate. Inlet temperature would seem to be more of an issue for a NA engine than a turbo.
Lets step back a bit. Tell me this...why would any manufacturer of a turbo/supercharged car go to the trouble to duct cooler outside air into it intake. And they all do. They spend time and money to design an intake that brings in fresh air from the outside. I am saying if it did not make a difference i seriously doubt they would spend the money to do it. They would just suck it right out of the engine compartment. Just another way to look at it.;)

Just to clarify, this chart shows air temperatures AFTER the intercooler. Specifically just after the throttle body. They are not the temperatures at the turbo inlet.



Greg
The data is exactly what you need to see. Temps after the intercooler going into the intake manifold. Empirical data that shows the functionality of the intakes versus the stock one.:D

That is pushed up far enough...it does not need to go past the index pin and fit flush to the turbo face...you can actually straighten it up so the gap is equal all the way around..some have removed the pin buy it is not necessary...just a matter of preference...
