[Vince@ V K Motorwerks]

I would like to introduce the VK Motorwerks Direct Mount Intercooler for the 135/335i.




Key benefits of the VK Motowerks intercooler:
• Approximately 82% Thermal Efficiency
• 40% increase in core volume over stock
• Installs in 15 minutes with basic hand tools
• No cutting, trimming, or any other modification required
• Bar and plate design for consistent high performance
• Internally staggered core increases the surface area that the charge air passes through resulting in better volumetric efficiency and lowers intake air temperature.
• Utilizes stock plumbing and mounting points
• Aluminum end tanks with CNC machined Inlet pipes
• Precision welded components
• Compatible with any tuning software
• Lifetime warranty against any defects provided to original owner


We had the opportunity to dyno our intercooler and compare it to the stock unit on a Dynapack dyno. You will notice that the stock IC requires and extra psi to achieve the power output of the VK IC. We only had time to do one pull with the stock intercooler and are sure that as more dyno pulls were performed the more boost will be needed to maintain the same power. No perimeters were changed between the two runs. All runs were done on the V3.1 1-05 stage 3 non-doomsday map.

The Car has the following modifications:
-VK Motorwerks Intercooler
-VK Motorwerks catless down pipes
-VK Motorwerks Oil Cooler
-Vishnu tuning Dual intakes
-Vishnu tuning Procede v3.1
-Rennart exhaust with resonators
-50% 93 octane and 50% 100 octane mix


The VK IC is the thicker green line





This Graph shows the boost comparison of both the stock vs VK IC.





This is a hp and tq values of our VK IC runs. I dont know why the graph says: Flywheel hp and tq, the graphs are actually showing at the wheel power.


Here is a video to demonstrate how easy the VK IC is to install:

This IC will be on sale on our website for a short period of time.
Intro priced at only $875!

Preorders will be shipped out shortly.

Glad I bought mine. One hell of an investment.

[lyjw88]

wow that is a true direct bolt on and great price too!

[Tobias1980]

Nice product Vince!

Your first graph confused me first as I did not understand that the point was the same power with less boost due to lower pressure drop.

I don't understand how your couplings are working - how are they sealing?

Nice work guys! Vid was really cool

As for the video did anyone notice the Gold diamond encrusted Liberace ring.........

Posted! sorry, I made this post at 1am.

[Sparky66]

All is forgiven......

[Ghost170]

I do not see the intercooler on your website, just the oil cooler

[Ghost170]

Is it ready to ship right now?

[mwahlert]

better pictures - not camera phone - would be appreciated! looks good though! well priced and direct replacement!

[Robmaster]

did you have a pic from your IC beside to the OEM IC?


and on the dyno sheet i dont see much more power with the VK IC...

They are showing how it makes the same power with less boost. That is the benefit of any upgraded fmic due to the pressure drop. You can then bump up the boost (among other things) for more power (ie. the stage 3 map for the procede)

+1 thank you for explaining.

Hey Vince..I know a few ppl are curious to see the factory IC next to your IC..can you post up some pics ?

But the problem is, I don't think it makes more power than stock on a stock car since it only makes a few hp more on a heavily tuned car ?

The V3.1 has IAT compensation; we ran both the stock and IC with the same map, tq settings, gas, back to back. The tune is set up in a way that it will make consistent power regardless of intake temps. We could have switched the map to the stage 2 for stock and made more power but we want to show you the efficiency of this intercooler versus the stock unit.

The first 3 runs were done on our intercooler which was already on the car when we came to the dyno so it was warmed up. We simply changed to the stock IC and did one pull, the tech there didn’t clip the stock unit right and we kept getting limp mode, so we had to take it off the dyno put the stock one in correctly and redyno we were only able to do this one time because the shop had to close. If we would have done more pulls the IAT's would have risen higher and you would have seen greater variance in the psi required to maintain the same power levels. I will post up some datalogs and dynos done at AMS on another car that we tested it on. Chris@AMS was great. The group that had preordered had already seen this info but we didn’t post it up because we were doing more testing on various IC cores and designs.

In summary, because of IAT compensation our cars will make the same power levels regardless of the thermal efficiency of the core. The gains will come when you install the new IC and turn up the tq values to compensate for the pressure drop. Perhaps, Shiv can enlighten us more about this and the workings of an IC.

[Vince@ V K Motorwerks]

The intercooler and catless downpipes will be available for sale on our website tonight. I will see if I can get my car on a lift to take a picture of the Stock vs VK IC. The cores are to arrive next week then we just have to weld the endtanks and inlet piping. We will ship the preordered units first.

Sorry, I did not understood much Maybe some dyno sheets made with a stock car with stock and the with the VK intercooler would me more meaningful ?

I have to say the direct mount idea is very good. Many people are looking for upgrades that do not require cutting the car. And there are not many alternatives on the market: Code 3 requires cutting, Helix is bolt-on only if you are lucky.

But we need specs and unbiased reviews...

Your still using the stock IC piping and stock boost tube, hmmmmmm........ :l

[Vince@ V K Motorwerks]

Our IC is still sufficent with the stock turbos and 15psi boost pressure we did not see any difference in thermal efficiency by changing the stock plumbing and using hose couplings.

The stock piping is not the problem, the stock IC is! Get that air cooler! Regardless of the piping, the amount and temperature of the air cooled from the intercooler will remain the same through the stock piping. I hope you understand this, and realize what a huge deal this DIRECT BOLT ON intercooler is!

VK Motorwerks does it again! First the oil cooler and now the IC!

[Juicer]

It almost looks like the FMIC is losing 10 to 15 whp between 5800 and 6600 rpm compared to stock. If this is the case it would be hurting 1/4 times on the map it was run on. It is boosting 1psi less which is good.
