We have the same car with the same engine, trans and turbo so why wouldn’t our 60-120 be similar? The APR 100 octane tune only makes 7hp more than the APR 93 tune. My car may be slightly lighter but he was also in much lower DA with a downhill slope. I bet if he swapped out his aftermarket hardware for OEM, he’d be right there with me. The Golf R DP sure is one nice piece. I bought another one the other day for my second wagon.
I would only accept actual side by side dynos for that proof. I dont think APRs dyno differences are accurate. I've seen your log and I've seen his Uni log. You hit 29 psi in third where he is barely brushing on 23 psi. Your timing is close enough. I know that 5-6 psi difference on my jb4 setting was worth a full second for 60-100. So while APR might claim 7hp, I guarantee it is more. Plus he is on Uni. I guess in reality he only needs to get his weight down to yours

A couple things here.

You’re using his boost numbers on 93, not the E30 he ran these numbers with. No doubt his boost and timing went up as the ECU adapted.

You need to stop looking at peak boost numbers. They’re pretty irrelevant. The only thing that matters is average boost from 4700 to redline as this is the general RPM range our cars see during acceleration.

While the APR Stage 2 tune runs a little more boost than its competitors it also runs a little less timing. As a matter of fact, it runs less timing than the stage 1 tune I used to run.

With that said, if he were to swap his hardware for mine, I see no reason why he wouldn’t be right there with me.
Next time I fill up I'll splash some E30ish and log it...curious as well how it looks. What is your weight complete with you? 3420 is as low as mine is going.

He's not on an e30 file. The only thing the e30 will do is maximize his timing. His boost still was peaking at 23 and tapering to 20. You are peaking at 29 and tapering to 25. His timing is only 2-3 degrees more at most onnthe e30. Yes he ran logs with the e30 and yes I've seen plenty of this file before when helping others stack on it. The APR 93 tune runs a lot less timing, but the 100 octane tune is damn near the stock and Uni timing curve with a lot more boost.
As far as him using your hardware is laughable. You can argue that the golf R downpipe will flow plenty well enough for the is20 on your tune, but you can not say it will be an improvement for him vs the downpipe he is using. A turbo doesn't work on back pressure in these marginal situations. So his will always be just as equal or maybe better.

Oh and Adam must be pretty damn small and light because our cars with us in them weigh virtually the same. Adam, how much do you weigh personally? How much fuel was in your car when it weighed 3420?
I'm 175 and the tank was 1/8 that day. I did the math based on weighing everything I took out as well as the calcs on the fuel and backed it out of my 3620 certified weight with full tank.

My factory OEM wheels and tires saved about 26lbs. The factory OEM battery saved about 8-9. So my total weight reduction is about 35lbs. However, Adam has a DP with no cats so probably weighs a bit less than my stocker with 2 cats. So then it just comes down to how much fuel was in both cars and how much he weighs personally vs me.
My Unitronic DP has a single high flow cat.

My wheels and tires are heavy. VW Blade 17x7 are 26ish lbs ea.

What’s interesting is the published VW specs for the 2018 4Motion DSG put it at a little lighter than the 2017. The same is true for the 6-speed and I think other trims as well. I wonder why the 2018s are lighter? Could be the different bumpers and such.
They started cheating out on sound deadening and stuff like that. Does yours have the under hood insulation? My 16 does, but I heard later years don't

I see 3338 for the curb weight of my 2018.

Yes sorry if I wasn't clear...93 only today. Early next week I'll get some E and send it.
I've seen a bunch of the file on a guy Ryan's car. Older file, but boost seems similar. E30 would only give him perfect timing. Not more boost. They probably work it on a boost target and then adjust timing based on fuel and IAT.

Adam’s car and mine are pretty close. Pretty much validates the whole 1.8T being at least as powerful if not more powerful than the 2.0 with all else equal.

Twindad, have you ran your car on ethanol yet? With the custom tune and two less wheels to drive, your 60-120 should be high 4’s to low 5’s I’m thinking? What’s your best so far on 93?
Still working out the kinks. I know the automatic shift will hurt a few tenths vs a dsg though. I also time 60-70,80,90 as well as 110. So this way I can see how it does before and after the shift. So on 93 with 23 psi of boost tapering to 20, the best was 6.63. The timing is pretty pulled back as well though. Only about 10 degrees total advance. Once we get the little bug worked out with fuel hiccups, he will add more timing and boost. Then we will go to the flex fuel. For that he said he will read the content and then adjust timing. So I'd imagine it will probably end up with something like a 25-21 boost curve at most

I was going to say based on the graph there’s no way you’re losing 2 tenths with the automatic. But I wasn’t expecting to see that kind of dip lol. So yeah, you probably are losing a tenth or two there. I don’t quite understand how you can hit negative g-forces lol but does that dip down to 0 occur at the same time as that weird RPM fluttering seen in your video? What exactly is that? Something related to the auto trans?
Yeah. The shifts are just lazy. In the old days this would call for a shift kit to firm them up, but nothing is available. There are solenoids for each gear. You can adjust a screw to adjust the shifts, but you would have to drop the pan for every adjustment. Go too far and the shift will bang too hard and jerk. So there is no real way to improve it. Just stuck with the factory sloppiness. I watched the APR video of their test car and concluded that the run was done on a dyno and bot real world conditions. I say this because I've gotten feedback from other auto guys and even seen their videos. Same laziness. Even when on a proper tune

This is why I also time the 60-70,80,90 and then 110 when I can. That shift can really affect the time and sometimes be worse than others. I compared those other times to see. These are where I sit with them all. Pulled the ones closest to each other. I did have a 6.43 on the jb4, but it was -.77% slope.
JB4 I Flash
60-100 6.81 6.62 6.47 I 6.63 6.80
60-90 4.33 4.23 4.19 I 4.45 4.41
60-80 2.65 2.62 2.58 I 2.70 2.68
60-70 1.29 1.26 1.23 I 1.28 1.28

Which APR video are you referring to? This one?


If so, that is definitely from the street and not the dyno. All of APR's acceleration videos are from the street.

I'm surprised your buddy Ian can't tune the Aisin trans. I thought he has a solution for everything.
There is no tune for them. It's all fluid and hydraulics. It's an old fashioned torque converter. He can change shift points, but that's it
I doubt the APR is in the street. The are going all the way to 125 on the stock tune. Its 55 seconds of acceleration. They would need a good mile long runway at least. Do they have that at their facilities?

My factory OEM wheels and tires saved about 26lbs.
Again with the misleading info....

I'm very excited to show you the latest OEM addition to my 2017 Golf Sportwagen 1.8T 4Motion DSG! These wheels were manufactured by Fuchs and weigh 14.875 pounds or 6.747 kg. They were only available as an option on a couple different trim level MQB A3s in Europe only. They're pretty rare.
They’re 16x6.5 ET46 just like the “Toronto” wheels that came on my wagon. I run 225-50-16 tires.
Your car was built in Mexico...& you basically admit it was NEVER a "factory option" for YOUR CAR.....

Its exactly like dropping in & claiming a 2.5lt, 5cylinder Audi TT-RS engine is "factory OEM"...Just because its MQB platform...

P.S. VW only run that rim with a tyre size of 205/55R16.....so your tyres, are NOT "factory OEM"....

Stop showing yourself up...

Here we go again with Dave, Mr. Nitpicker.

I never said the tires were factory OEM. I said my “factory OEM wheels and tires saved about 26lbs.” The wheels are what’s factory OEM, not the tires.

The wheels are a factory OEM part. They have a VAG part number.

Were the OEM 312mm brake rotors you have ever an option for YOUR Golf 1.4T Dave? If not, then by your own logic “Its exactly like dropping in & claiming a 2.5lt, 5cylinder Audi TT-RS engine is "factory OEM"...Just because its MQB platform...” 😂
An Audi TT-RS engine has a VAG part number & therefore under your statement of ."The wheels are a factory OEM part. They have a VAG part number"..you would claim a retro-fit as "factory OEM"..

Your wheels were NEVER a factory option for YOUR car & therefore NOT "my factory OEM wheels & tyres"..& if your tyres were factory they would be 205/55R16 size..

This thread is about accurate draggy times & posting up the specs of the cars & what modifications have been done to achieve this...you are repeatedly giving out misleading info as per usual...

As for your last statement of "Were the OEM 312mm brake rotors you have ever an option for YOUR Golf 1.4T Dave?".....

Yet AGAIN proving you don't UNDERSTAND my build thread or how to guides...or read what I have previously posted on this...as someone asked the same question in the other draggy thread....

On my 1.4lt GSW, 312mm front brakes discs were a factory fit option to order in UK, in conjunction with the DCC dampers & alloy hub carriers....However, I have NEVER claimed they are "factory fit"..although they are more "factory fit" than your wheels & tyres...

People have repeatedly asked you to post videos of your GSW, & you have refused...& considering your propensity to mislead people I wouldn't trust the validity of those draggy slips being done in a 1.8lt IS20 AWD GSW...

Here are my calcs on weight. I actually weighed all the "stuff in vehicle" which was primarily my roof-mounted bike racks, emergency/safety gear, personal odds/ends, HD floor mats, cargo mat, etc. My full weight included 14.5 gal of gas. Curb weight should include spare tire and anything the car comes with from the factory - not sure how they deal with fuel. Next time I get excited, I'll actually put it on the same scale lightened-up and verify it - it's $12 and it's right by my client's office in Mexico.
