Big Turbo MK7 Golf R taps out.

We get our salvage MK7 Golf R on the dyno. We make the most power we have on a stock engine MK7 R but things take a turn for the worst.
Next video will have more details of what took place.

This car engine its overdue 160k miles lol

[@4BillC]

I currently have an 01 Audi A4 1.8T with a K04 20psi and methanol injection that has right about 200,000 miles on it. I drive it every day and not all that nice to it. I have a gt28 for it but I also have everything I need to rebuild it, which is getting done soon.

[@UngluckInc]

@@4BillC 260k miles over 14 years making 500whp in a MK1, 1.8BT ftw. drop in rods(aged arp 625 fasteners), re-used pistons with fresh rings and a light hone. OEM bearings.the amount of track time I have on it is crazy, as well as daily duties and cross country. Def an incredible engine the 1.8t20v, but my '17R has been incredible for it's 75k miles so far.

[@4BillC]

@@UngluckInc that's what's up! That's basically my plan! H-beam rods, stock pistons new rings and bearing. Going to keep the stock valves but upgrade the springs (only bit I don't have yet) just so I can rev a bit more. I currently have the rev limited to 6800 just because I'm scared of valve float. I want to be comfortable at 7500.

[@BrodeyDoverosx]

Methanol for everyone.

We already talked about it. Lol I'm gonna sit and chill on it for a bit before I make any decisions. This was supposed to be a quick go have some fun project and It's been a huge undertaking and it's time we could have been working on the drag car.

[@IcanDriveIt]

I love turbo 4 cylinders but damn we ask a lot of them. Sometimes they hold up, sometimes they don’t. Metal fatigues.

[@COMotorsports]

I think this one was partial part failure (sensor) and greed that killed this one. More in the next video.

[@walls430]

How much boost were you running when it let go?

[@hellaflushhonda]

Dang about 169,000 miles I bet refreshing the motor a little and changing the oil would’ve helped! Good content tho!

Cant let all those goodies go to waste!!! Spare motor with internals for the redemption!!! Did u guys use pump gas or a mix of e85? I love this channel for vw content!!!!

[@COMotorsports]

This was e70. Much appreciated.

[@itschefff]

The bad O2 sensor and cutting out you mention, is that common? I seem to be running through O2 sensors fairly regularly (three in the last two years) and no one has been able to figure out why the car will just give up mid-pull. We’ve replaced my wastegate actuator thinking that was the problem. The turbo itself doesn’t have a ton of miles (under 10,000) and the internal wastegate still seems good but when it’s deep in a pull it will just release all pressure like the wastegates opening. If it matters I have a fully built bottom end but the head was rebuilt with stock parts at the recommendation of the shop that did the rebuild. Prior to the rebuild it made 458whp on 91. Now it’s making 375whp on E85 and it’s stumping everyone.

[@andyk1882]

sounds like you have been shafted bud

[@MeltingRubberZ28]

Damn that's frustrating. Idk what that could be. Hopefully it's not the same issue this one has/had heh

[@COMotorsports]

Not typically but like anything in a car things fail. What vehicle are you referring too?

[@itschefff]

@@COMotorsports 2016 Golf R. It has a pretty extensive build sheet but not everything is meshing together for some reason.

[@COMotorsports]

@@itschefff You shouldn't be eating through sensors, especially if you have an OE frame style turbine housing. If you have something aftermarket and the sensors in a weird location or getting water on it then that will take them out.

[@workingemail2218]

How did you guys like the boss750? Considering picking up a used R early 23 as these prices start to drop. Thinking of doing a "low budget" R build with a stock/catted downpipe, stock motor, stage 3 clutch, boss750, MPI, and an LPFP. I once had an IMS710 R with a DQ500, but that was completely unregisterable and it broke axles constantly (and a lot of other shit). Looking to build something more tame, manual, and daily-able. 500ish whp and 420ish torque.

[@COMotorsports]

I think for 500whp, Go smaller.

[@workingemail2218]

​@@COMotorsports hybrid? Personally not an EQT guy, but have been looking into TPC as a potential option. APR offering is okay, the garret unit has a ton of surge down low.. I assume you recommend the XL?

Hello CO Motorsports! My name is Timothy and I have a minty mint 2016 Jetta Sport 1.8T completely stock. I want to build my car up towards Stage 2/3. Is it possible to start with a stage 2 tune, intake, exhaust and then later install a big Stage 3+ Turbo Intercooler setup. I am 34 and I am currently fighting severe skin cancer and I would love your help/guidance. Please get back to me. Tim H.

[@COMotorsports]

Sorry to hear Tim, typical turbo upgrade for these is GTI or Golf R turbo. Whatever software you start with just ensure they offer a turbo file for those turbos so you're not purchasing different software down the road.

[@Sirclaude82]

can u show result in NM sometimes?

[@COMotorsports]

Not the standard here in North America. Just do the conversion if you're curious.

Just because yours busted it’s garbage?😂😂😂😂

Very much disagree. I have several customers running 500+whp daily. If your engine crapped out, there was something else involved (bad tune, bad maintenance, bad parts, etc.).

@@deciplesteve agreed

Definitely disagree these guys pushed a high mileage dirty engine oil car. This happens. These engines are super strong an exact 500hp big turbo build is definitely a daily for this car. Being able to add 200 hp and stay dependable is definitely a thing for these cars

Bullshit. Have literally hundreds of customers with GEN3s running my tune, 3xx, 4xx, 5xxWHP, all for years and no issues at all. Tune these engines daily and no issues at all, have owned 3 GEN3 cars, Cupra 265, S3 8V, A1 1.8TSI GEN3 and all of them with upgraded turbos and making hundreds of horsepower more than stock with no issues at all
