Tiguan IS38 and Big turbo upgrades

I've started the parts collection - Racingline R600 intake on order...

Yes Haines use Motul and there's a big plus for doing everything under the one roof as 100% accountability with the workshop. You don't get one workshop blaming the other workshop for poor workmanship and be the guy stuck in the middle.

RD Technik will do a remote dyno session so it will get dyno tuned and they are one of the few people that write DSG files locally to match with your torque/power curve so that gear changes keep you in the power band. Plus can add in crackle maps and DSG farts to customer preference

Sounds good, make sure they enable boost on launch to optimise take off.

I’ve only read good things about this intake. Are you getting the intake elbow and turbo inlet to maximise flow? Also you might need a kit to re route the coolant hose, unless you can live with the hose coming over the top of the box.

OK so 30psi requested boost with launch @ at 4,000rpm??

There's also a bit of a compromise between super fast shift speeds and DSG farts as the faster you shift the less farts you get.

LOL - not sure I’d have it that high....just enough to have the perfect launch..if not you will just be roasting your tyres!

Enable crackle and pops for some added pops and bangs.....unless you have a cat....it might fry it with the fuel over run.

Rather have fast shifting...

I haven't ordered the other bits. I'll have to check what parts the new turbo comes with. I may just need the silicone intake elbow but not sure how much difference this is going to make.

And haven't done anything about re-routing any other lines. Will have to investigate this a little further....

Yeah I'm not going to be doing anything too stupid. I'll be keeping this one for 100,000+km so I need it to be making reliable power.

Yes if I can I'll get some mild over-run crackles in S and M only.

And I'm with you fast shifting > DSG farts. That's why you don't get much noise from supercars on gear changes as they are often shifting too quick.

In the link below you can see the coolant line in the OEM position and sits in the front of the stock air box, with R600 installed it sits ontop of the R600 cover (5th pic in the link):

VWR R600 Part 2 - Install and final thoughts - GOLFMK7 - VW GTI MKVII Forum / VW Golf R Forum / VW Golf MKVII Forum

There are kits that reroute the coolant pipe, underneath the airbox, like the one below:

Spulen MQB Intake Coolant Hose Solution - SE-MK7CH - 5987

I nearly got one, but worked out for my purposes the stock box is well engineered and with additional intake mods, flows well for up to 400 HP. For over 400 HP the R600 would be a sensible investment

Thanks for that. I'll do some more study before getting the installation done.

I was hoping I'd be able to get away with the stock airbox just with a high flow panel filter and some modifications, however I don't think it's got enough flow for stage 3.

Similar with the intercooler. You can probably get away with it on stage 2 or with an is38 but by the time you're heading to stage 3 the stock intercooler just doesn't cut it.

TCU TUNE UPDATE

So I got a bit itchy knowing I had the TCU software file ready on the laptop and snuck to the garage to do the TCU software install.

Connected the battery charger/maintainer and hooked the laptop up to the power, powered on the car (not started), put in the OBD personal flasher and I selected the TCU type and the MOD file. Note, the DQ500MQB BOSCH shares the same circuit board as the TEMIC DQ380.

With a slight hesitation I pressed the “install” button and some lights flashed up on the dashboard and some beeps could be heard. The installation bar came up and said 4 minutes and I saw that the file was being written.......my heart raced then before I knew it another prompt flashed “installation complete.”

I powered off the car, disconnected the laptop and charger and was ready to go. Strapping on the Vbox, I thought “what the heck” let’s go for a run. It’s dry and reasonably cool at 18 degrees c...

Straight away you can feel the clutch grip firmer and stay longer in gears in D. I went to my usual spot, my heart pulpitating like I’ve ran a marathon and waited for my car to reach operating temperature.

Ensuring it was safe, ESC off/sport engaged, gears in S mode....I enabled launch control. “4000 RPM” dialed in - it sounded like a rally car. Releasing the brake and flooring it I was thrown back in my seat.....definitely a more forceful launch. The front wheels spun like a GTI with race gas momentarily then gripped....the gears raced by and changed with medical pin point precision.

I pulled over and looked at the vbox....

0-100km/h 4.1s

I had beaten my pre-TCU tune run of 4.2s. TVS engineering, a bloody good tune. I’ll do a full review once I’ve had to drive it for a couple of more kms in the burbs and on the freeway.

I’m sure with better tyres and less wheel spin I will be able to dip under 4s.

What a night....

Time to eat my hungry jacks and head off for bed.
