*** VRP Intercooler Package for V12 BiTurbo ***
After many months of testing and revising we have finally come to the production version of the intercooler upgrade package for all MB BiTurbo cars.
The original prototype pieces that were created and fitted onto the CL65 were a bit too big and had clearance issues. They also had very square edges and introduced some issues with respect to bleeding the intercooler circuit.
Below is a pic of the original design for reference:
The new design introduces round edges for better clearance and flow. In addition there were CNC'd intercooler nipples and turbo discharge flanges which mates everything up very nicely.
Here is a closeup shot of the CNC'd turbo discharge flange that we created.
Here is a closeup of the Y-pipe which has rounded pipes to allow a smooth merging of discharge air from each turbo. The stock "Y-pipe" is better described as a "T" rather than a "Y". The discharge air meets in abrupt 90deg angles.
Just to give you an idea of the difference between our upgraded coolers and the stock ones, I have included a picture which shows a comparison of the 2.
And finally, here is what the new design looks like when they are mounted to the car.
These pictures are of a kit that is going out to a board member here.. This first kit we are hoping to ship out mid next week once the new intake pipes and filters are fully assembled.
I am also happy to announce that we were able to shave off a few more bucks from the kit price
This upgrade package will include:
Priced at: $7,495
If you would like to order a package we require a $1,000 deposit to secure your spot. I am making 10 sets and they will ship out in the order the deposits are received.
Deposits can be sent via Paypal to: sales@vrptuning.com
If you do not have a paypal account please send an email to sales@vrptuning.com and we can make alternate arrangements.

Very nice Victor.
Maybe you could help clear up some confusion that was started in another thread.
What is the power output of this package on regular pump fuel? In the first post you mentioned you were calling this the 825HP package with 692rwhp. In another thread someone mentioned that was running on 110-103 octane. A figure of only 571rwhp was thrown out there running on the intercoolers and intake setup.

The coolant tank we're referring to is a small overflow tank which converts the current system to a pressure less system. It is going to be mounted in the engine bay.
The only Dyno I am aware of with this version of intercoolers is my 692RWHP. There is a 571rwhp dyno out there that was done with something completely different than either of our two versions.

A small overflow/fill tank that will be in the engine compartment. This makes the system more user friendly and helps prolong pump life. It eliminates the need to bleed the system at the dealer.

& do you have any idea of what the upgraded IC's alone made on the dyno? RWHP/RWTO or/and Scorpion Intake? I'm going to be buying this kit in stages
Lastly since this 692/912 Dyno was on 100+ Octane, any dyno while using only 93 Octane?

Vadim, is the IC install EZ for a do-it yourself job as it looks? I don't wish to compromise my 100k mile DC Warranty, so I'd be swapping the stock IC's back on for Warranty work. About how long would you guess this part flipping to take? What about fluid draining/filling? (I've done plenty of CAI, throttle-body, MAF, radiator, A/C, Alternator, serpantine belt, replacements in my time, on various auto's but never InterCoolers?)
Also could you send me a PM on various Stage pricing for IC's & Scorpion CAI alone? This will make it easier to digest than doling out the full amount in (1) lump some, & possibly a bit more fun seeing how much HP Torque each part adds... Thank you for your time!

Hey Rob!
Marko runs 100octane in the car all the time. BUT, its not to say that he has a perfectly dialed in 100octane tune in his car. He is still running conservative timing even for a 93octane car and his A/F is out of whack. Saying all that, he still managed a 692rwhp 912rwtq dyno pull.
To be honest, we really dont know what Marko's car will do on a 93octane tank of gas on the dyno, but, I can tell you that we were "racing" it in Detroit when we got together down there and he was running 93octane in the tank. He still managed to put buslengths on a Kleemann tuned CL600.
The 571rwhp dyno that Vadim did was with an entirely different setup than this one. Different intercoolers and tuning.
Its a small coolant overflow tank that you can mount somewhere in the engine bay. I was considering just using a small 2gallon remote mount reservoir and trying to fit it in the engine bay or inner fenderwell area... Still tossing this idea back and forth.
Nick.. Let me know when you are ready.. The initial run is being limited to 10sets for now.
You are next Marcus.. 
It includes the downpipes.
You cant buy the intercoolers without the intake setup. Those 2 have to go together because once the coolers go on, there is no hope in hell of keeping the stock airbox. The only thing you can separate is the tuning from the price. Even then, I havent tested the bolton kit on a stock tune to make sure A/F are safe.
The install is VERY easy.. 2 - 3 hours with basic hand tools.
Thanks bud!

Does your 692rwhp 912rwto dyno include the exhaust work you had done? IE (1) off Cat-less Down-pipes
& do you have any idea of what the upgraded IC's alone made on the dyno? RWHP/RWTO or/and Scorpion Intake? I'm going to be buying this kit in stages

Once again, great job guys! Unbelievable HP gains, this will scare away even the F-cars now, I just wish I had a V12 to play with, with this much power what else do you need?

Hey John!! I was hoping they were going to be able to get you over but I know your schedule didnt coincide..
We will be making another appearance in the near future so I look forward to seeing you!
Make sure you are available for the spring gathering at the airfield!!
Marko's CL65 and a bunch of other quick ones will be there.

Jury's out on this Q: I think they're listed under different part #'s but Turbo sizing looks to be the same
If my memory is faulty please correct me? & I'll edit my post VRUS
But from my own research the extra .5 Liter displacement advantage the 65 has over the 600/5.5 Liter ---- 65/6.0 Liter would be negligible, it's all up to Turbo sizing.....Just as I remember VRUS saying..

Who's Intercoolers are these? Are they RENNtech? What's the major diference from yours besides the cool piping? What is that piping supposed to do vs VRP plain box-style?
I would imagine the VRP basic box-style must have more total coolant capacity?
Also are those Scorpion Intakes, VRP? or RENNtech? they look identical
& Where do the bottom of the Scorpion CAI connect to? in your close-up picture it is hard to tell or see any mounting point? (I've never completely taken off my stock air-boxes & looked under them..
These pix are from an SL65

It was a valid question, I only wondered whether the cooling setup was going to be modified for our cars as well. Had no idea it was the highest traffic area.

@The ricker
The three airboxes are all VRP. Those are different prototype built before the finish product shown in this thread.
The airboxes are connected to the turbochargers who aspire the air . The compressed air flows through the coolers to get cooled and then in the engine itself.
On this pic you can see clearly the airboxes connected to the turbos
