1.8T APR Stage II with APR Downpipe Dyno Results

As luck would have it, a local speed shop installed a dyno recently and I went to one of their Wednesday dyno events. My car has an APR Stage II with Downpipe tune. I also have an Injen CAI (never caused any heat related issues) and the Golf R intercooler.

The red line is a fourth gear pull and the blue line is a third gear pull. It was mentioned that there is some compressor surge at low RPMs and it runs a little on the rich side for a DI car. Either way, I have enjoyed the tune and am pleased with the results.

Still awaiting for that IS20 map...

I say jump straight to is38.
Fix that huge drop off after 4.5k

Solid numbers very close to apr numbers if I'm not mistaken

It's actually alittle better than what APR claims, but considering the differences between dynos, it's pretty much spot on. Although an IS38 tune would also be nice, I am not sure how much extra lag it will bring.

Wow, those are MK6 GTI Stage 2 numbers haha. Great stuff. I think the IS20 is a better match to the 1.8T, but that's just my opinion. .2L of displacement makes a HUGE difference in spool time, not to mention you can grab IS20's for ~$200-300 dollars.

Agreed with goingnowherefast. I think the real selling point of an IS20 turbo swap is that a used IS20 is so easy to get a hold of. It would also encourage more GTI's to go IS38 because then there's a better chance that they're old IS20 will go to good use.

Also, the power curve from the few people who have done it makes the IS20 look like a perfect match, with the peak power right at 5700rpm. With the IS38 I'd be concerned that the peak power would be too close to the fuel cutoff and everything before that would just be filled with turbo lag.

Yea, I'm not sure if I would trust their reliability with my car, but at the very least it's proof that it's possible and has very good results!

Good to see this. Still waiting to see if 10whp is worth the price of the downpipe though... Unless it makes significant more top end power over their Stage 1. Looks like you are close to 220whp at 6k, where my Stage 1 is just barely making 200whp at the same RPM.

Honestly, I didn't feel a huge difference with the upgrade to stage 2. It probably shows itself better on longer highway pulls, but I never timed it. It will probably show more of a benefit with an IS20/38 tune.

The acceleration numbers show where that stage 2 is worth it. Take a look at the 0-100 mph times on the 2 tunes and you will see why a stage 2 will walk away from a stage 1. Also, check out the 1/4 mile thread. Stage 2 running a 13.8 with a real bad 60' time. I think the stage 1 cars are over a half second slower than that. Peak numbers don't tell the whole story.

I understand that, but the numbers don't show a 1/2 second faster 1/4 mile times with 10whp. That 13.8 was also a 5 speed manual with DR's, my auto will never see that time.
