I am sure most of you have been following moacur's as well as flyboy's build-up threads, well now here's another. It seems C2 Motorsports has really been up and coming with their R32 turbo kits. At Waterfest this year, I was lucky enough to meet Jeff. After talking with him and seeing the quality of their 24v VRT kit, I knew I had to have their (in production) R32T kit. Jeff was very informative and knew what he was talking about. This again made me confident in C2. Then H20 came around with C2 announcing the release of their C2.400 kit. Moacur was lucky enough to pick up the "first" kit. After following his thread, reading the reviews, seeing the car in action, My mind was made up. The order was placed and production had begun. This was the first "new" C2.400 kit. I believe Flyboy had placed the order for his kit around the same time.
The Wrap Sheet:
C2.R32.400 Turbo Kit:
PT35R turbo
SS Tubular Turbo Header
Tial 38mm WG
SS 3.00 Down Pipe: V-band Equipped
SS 3.00 Mid-Pipe Kit
-Connects to DP
-Retain Stock Mufflers
-3.00 SS Hi-Flow Cat
-Mid pipe (~40.00 long)
-SS Couplers
SS Intake Pipe: Turbo to TB
R32 Fuel Kit
-6 Larger Injectors
-6 Injector Harnesses
-4.00 Open-Element Filter
-R32 Turbo Flashload
SS Lowered CR Spacer
-T304 Stainless
-Laser Cut for Factory Fitment
-OEM Crush Gaskets
Raceware Head Studs
“The Bat” 4.00 SS Intake w/MAF
Forge DV
The Installation:
http://www.apextuning.com took care of the build. I have known them for almost 3 years now and I knew they were the guys for the job. They were just as excited as I was about the build. The first plan of attack was to tap the oil pan and put in the new lowered cr spacer, but C2 had told us they could produce the kit quick enough to try and get it done all at once. There were some loose ends due to the rush delivery of the kit, but Chris at C2 was very helpful with making sure we got taken care of. The guys at Apextuning really put an effort into the build. They did run into some snags, but they stuck with it and really pulled it off. Words cannot describe what really has been put into this build. I can say all the aggravation was worth it in the end

The Performance:
Image
was my first expression. Everything from boost coming on to the idle is perfect. The car runs so smooth yet produces enough power to keep you in the seat. There is no little noises or rattles. The GHL cat-back really helps the .:R open up and the sound is fantastic. C2 have really produced an awesome kit. The kit seems to be very reliable for the daily driver and provides great power. The .:R has been on the road for about 2 weeks now. When I get on it, full throttle scares the **** out of me. The .:R alone is a great car but this kit makes it that much better.
In the weeks to come I will be putting it on the dyno. After that I plan to do water/meth as well as a clutch and throw it on there again. It will be great to see what moacur's numbers as well as mine turn out to be. Sorry for the crappy right-up I have been short on time. Here's some crappy pics (I hope they work). Please excuse the engine bay as things still need to be cleaned up. I will also try to get some video up asap so keep an eye out.

This is the kit for $6999 with no intercooler?
How much boost does that kit run? What RPM do you get full boost?

Correct. The C2.400 has no intercoller. Kit produces 11 pounds of boost.
Here is the Dyno of the C2.400 at H2O.
368fwhp
333.2fwtq

Re: C2 Provided/Apex Tuned. (flyboy3069)

more pics will be on the way soon

the only major issue the guys at Apextuning faced were rerouting the coolant lines. while moacur's kit came with necessary lines, Apextuning had to come up their own solution. remember these kits are fresh off of C2's shelves and I am sure a solution is already in place with any new kit that leaves C2. All in all it is an amazing kit with a great tune which is sure to put a smile on anyone's face.

Re: (moacur)

1 athmosphere + 11 pounds of boost = 1,75x240 = 420Hp
420Hp-15% = 357AWHP is what 11 pounds should give you.
420Hp-EIPliketrannyloss20% = 336AWHP
Image

Check with Jeff C2 if you need to do any adjustments and get the last 30hp back thats missing on 11 pounds http://****************.com/smile/emthup.gif

Or if its just dyno error with incorrect tailsniffer

I think you and Ian (Daemon42) are tied for "most knowledgeable about the MK4 R32"

so 15% is the accepted drivetrain loss for our cars now? if so, they aren't the only company missing hp

Since I believe most of Foffa's experience is tied to the 12V VR6, not the R32, I'm pretty confident that Ian is still clearly in the lead...

I think that 17-18% on an awd dyno has proven to be accurate for the R32. http://****************.com/smile/emthup.gif

No we acctually started of with the 24v back in 2001 and then we started to work on my VR.
So its basicly 50/50% wotk on both 12v and 24v.
And for the figures of drivetrainloss it is 15%
And with the guy dynoing back to back FWD vs AWD and providing the R32 forum with even more info of that if you sell a product that dont deliver just add some more % to drivetrain and you have som AIR-Hp to add to you list
Image

All engines are the same.
Its basicly a air pump.
All calultions for gas speed still applies , port size calc , runner calc and other stuff still applies.
And best of all ...... Athmostperic pressure is also the same on both Honda and VW
Image

But lets do this again
240Hp - 15% = 204AWHP
Just like most dynos they get 205-225awHp depending on model and what spec software you got.
204AWHP x 1+0,75 = 357AWHP is what you should get at 11psi.
Back in the days my VR5 HGP/HPA kit said 280Hp at 0,9bar
And fast calc on 150Hp x 1.9 = 285Hp
So it wery easy to see if product can make claimed target .
And it acctually dynoed dead on. http://****************.com/smile/emthup.gif

But call Jeff and C2 and make a pressure test of piping system.
Small leak and hp goes down quick.

your calculations do make sense, I am sure every C2 kit will differ a little. I can sure vouch for the kit producing more than 320 awdhp http://****************.com/smile/emthup.gif

yes , small difference.
Some will actually give you ~ 224Awhp x 1,75 = 392Ahwp
But this car need to get pressure piping system checked because its basicly under the lower limit because if it only had 220Hp to start with its way low.
So do a pressure test.
Go to atleast 2bar to find all leaks http://****************.com/smile/emthup.gif
