So to start off with, I picked up the 07 GTI right from VW as a CPO. It drives great right out of the box, but that's never really good enough :-)
After a little bit of research here on the Vortex, I opted to replace the factory engine cover/horribly restrictive airbox, and chose BSH as the source for my new intake components. They are another company that started from scratch and still run everything in house.
The first order was for:
BSH FSI True Seal Intake
BSH FSI Heatshield
BSH FSI DV Kit for TS Intake
BSH FSI Integrated Throttle Pipe
BSH FSI PCV Fix
New South Performance MKV 2.0T Vent Mount Boost Gauge w/ BSH Billet Boost Tap
Obviously giddy as a school girl, I installed the BSH FSI True Seal Intake as soon as it arrived last weekend. The install itself was pretty straightforward, although it took some head-scratching to get the rear-engine cover mounting screws/brackets off. (Video coming soon)
The sound of the BSH True Seal Intake is only slightly louder than the stock airbox system. With the metal piping and cone filter, you can hear the turbo and DV a little more, which is always a plus.
The next piece I opted to install was the vent-mounted New South Performance Boost gauge, so I could get an idea of where the factory system registered on a daily basis before we got into the build. I chose the vent-mount for the cleaner-looking install, versus a pod-based setup. To each his own. (video coming soon)
To get this gauge to work with my near-stock system, I opted to use a BSH Billet Boost tap, instead of screwing and tapping into my intake manifold like some installs. This was also a super-easy install, sitting right in between the intake manifold and related PCV hosing. (video coming soon)
I can see now that all day long, every day, the stock 2.0T FSI seems about 10-12psi stable (dropping 5-8psi at high-rpm) and pulls nicely.
The next step in the build is to free up some of the back-pressure with a new exhaust system. The stock MKV GTI exhaust looks to be a little less than 2.5", and without running a big-turbo, high-pressure system, 2.5" seems more than satisfactory.
I've opted to go with the stainless Techtonics Tuning 2.5" catted downpipe and matching 2.5" stainless cat-back system with a single Borla muffler and twin tip. (video coming soon)
The suspension mounts underneath the car make a great spot for jack stands. This ended up being quite useful during the install.
The Techtonics downpipe is considerably less restrictive than the factory DP and mated to the 2.5" Borla exhaust system, frees up some noticeable horsepower and an awesomely sporty sound.
To suit more of the aesthetically anal person inside of me, I've gone ahead and also removed the oil filler expansion, since I don't plan on re-installing any engine covers. Be careful when you remove this...plastic shards in the engine are not conducive to performance :-P
I stuff the filler neck with some non-pilling shop rags, and gave the neck a few whacks with a rubber mallet. This is attached with some glue that just needs to be broken free.
The next step in the build process was to install the BSH PCV Fix. This was a pretty simple install as well, the worst part was actually getting off the old PCV hose. The factory PCV system on the 2.0TFSI left something to be desired, especially when you start modifying the motor. Where I've already installed the BSH Boost Tap, this saved me one step as the block-off mounted right to it. (video coming soon)
I've gone ahead and scheduled an appointment for Monday for a Stage 2 APR Flash. Since the business hasn't yet had the opportunity to get an agreement setup with APR, I've scheduled the tune with Banchworks out of RI.
Since the new wheels and tires showed up from TireRack, I went ahead and mounted them up as well. :-)
I've chosen the new Sparco Assetto Gara (manufactured by OZ) as I think they look uber sexy and the black wheels will make a nice contrast against the Reflex Silver. I've opted for 17s, as New England is horrible for 18s on a DD.
And yes I know.... NEED MOAR LOW The Konis/Vogtlands should take care of that in a couple weeks.
The next logical step in the build is something to manage all these fun parts I'm adding to the car. Thanks to the fellas over at Banchworks , I am now running the APR Stage II+ @93 Octane.
People aren't kidding when they tell you that this is a game-changer folks. All these mods have felt great so far, added some liveliness and so forth, but this APR reflash is the icing on the cake that made all these parts so far worthwhile.
Now that I'm pushing some more pressure, it made sense to clean up as much airflow as possible, so the next install was the BSH FSI Throttle Pipe. (video coming soon)
It actually seems like I can hear the turbo spooling a little more and quicker. I opted to keep the noisepipe hookup, as I'll be doing the BSH DV relocation kit w/ Forge DV next.
Tbh, this install was a little bit of a pain in the butt. Getting the factory throttle pipe out was a wild pain. Tip #1, disconnect the noisepipe hookup from the noisepipe itself, not the throttle pipe, as it'll be easier to swap later. Tip #2, when installing the new throttle pipe, install the coupler on the throttle body first, then squeeze the pipe up from under the car and get the alignment setup from there.
I also lifted the car up again and did some tweaking with the exhaust clamp setup, as I had some contact rattling and a weird exhaust tip angle (as previously pointed out), so I went ahead and cleaned that up as well.
Once the weather cleared up, I opted to install the BSH Bulletproof DV kit next (with the Forge recirc. DV). The install was pretty straightforward, and reused almost all of the factory noisepipe hardware (video coming soon)
Took it for a little run afterward and ran some VAGCOM logs (rpm/boost) to see what she's doing after the APR Stage 2+ and the rest of the mods. I'm seeing some pretty decent mbar #s, but I'm going to graph it out before posting it up to the thread.
Here's the log (graphed from csv, thanks to my lovely lady):
Everything seems up to par, but I think I might do a few more logging runs, maybe through ALL the gears.
Next install we're looking at is a set of Vogtland 40mm drop springs along with Koni Yellows (adjustable)
After what felt like a couple of fuel cuts at WOT the other day, I decided to a few log runs with Boost/RPM/Fuel pressure to see what was going on.
Sadly, as you can see by the following graph, the stock HPFP can't handle the work the APR Stage II+ is throwing at it.
Now APR states pretty clearly that an upgraded FSI HPFP is needed for the Stage II+ and they were 100% correct.
< follow link to APR for more details.
I've already ordered an AutoTech FSI HPFP rebuild kit as I haven't been able to find any gripes about it (versus KMD for example) and the APR HPFP is a little out of the budget. Should hopefully see that in a week or 2 and we'll continue with the installs.
The Koni/Vogtland setup is now installed and it looks great.
While I have been doing all of the installations myself thus far and recording them all for some DIYs, I did not have many of the tools needed to properly install this suspension.
I opted to call up the guys over at Banchworks again for the install. Quick install and great price.
I know there will be some of you out there who are going to say MOAR LOW, but I don't care. This car is still a DD and where I went static, ~40mm is a sufficient drop for good handling.
Now I just need to wait for the AutoTech HPFP rebuild kits to come back in stock, since they are nowhere to be found and I'll be all set to make a few dyno runs and a trip to the drag strip for fun
AutoTech HPFP kit finally came back in stock and just got delivered. Now I gotta plan some time for the rebuild.
Also swapped out my "red" tails for oem/votex smoked tails.
I Fiiiinally got around to installing the AutoTech 2.0T HPFP rebuild kit. Install was pretty smooth, although I had a few bolts that didn't play along nicely.
I plan on getting in a few logging runs tomorrow so I compare the before/after VAGCOM graphs and make sure the HPFP is performing adequately.
I also installed some R-Line textured mirror caps and a full Euro GTI front lip to complete the package for now.
So I finally took the GTI to the drag strip last weekend to get in some runs and see if all these parts are doing anything for my numbers.
First run down the track...I forgot to disengage the traction control and it was horrible. Ran a 14.8@93mph lol. . I let my wife take a run down, since I would have one more run for qualifying, and about 3/4 of the way down the track, a cloud of white smoke blew out from underneath the car :-(
The coolant sensor flange on the drivers side of the block cracked and blew out, draining all of the coolant out of the block. I ordered the replacement parts and attempt to repair it this weekend, only to find the VW gave me the wrong part(s). I called them up to gripe, and come to find out...it's covered under my CPO warranty :-P
So needless to say, the car is at the dealer getting repaired.
While doing the flange repair, I installed a euro Audi S3 shifter (from this guy)and it's pretty tight. Haven't been able to drive it yet, given the circumstances but the feel is snug and the install took minutes.
Hoping to feel a difference when I get it back from the dealer and take it back to the track in 2 weeks.
So I picked her back up from the dealer last week after the water pump started leaking. Thankfully I still had 1800 miles left on my CPO warranty so they covered the service. With about 73k on the clock, I opted to have VW do the Timing belt service for me (at a discount, since they had to rip half the stuff off to get to the pump.)
I also decided to swap out my BSH PCV Fix plate in favor of a Forge Catch Can (Thanks IDRIVEFAST). Scored a nice deal and I'm hoping it'll help with all the excess vapors that keep clogging up my Forge DV. (mentioned in later posts in the thread)
Super easy install and it should help out quite a bit. I'm thinking about dropping her off to have someone (maybe even the dealer) walnut blast the intake valves, etc and getting on a good SeaFoam regiment. the Catch Can should help out the process even more after that.
Stayed tuned for more...
