My dragstrip in Mexico has been full of cops for a while, I've been on the search for a new one ever since. This looks perfect, gonna have to look more in Karstakastahn.

Railway... First clue!

1/8th mile is probably more likely, unless I find a really good straight roads around here that is somewhat secluded for a full 1/4 mile. There is enough farms around here where it's a possibility, which also means some of the roads are pretty garbage. I'm not looking to end up in a tobacco field or blow past residential homes at 100+mph. I know of some places that have potential, just got to find the time to get there.

See if you can at least do 60-100.

So... TLDR I read a few hundred pages, skimmed a lot, but has anyone actually tuned one of these on say a FBO/MPI/E on custom software setup yet?

There's one up on Dragy. Certainly a capable turbo, just doesn't spool all that fast.

I'm curious how this would look on the 1.8s but I think the slower spooling that I'm reading here would be accentuated by the smaller 1.8 without the exhaust cam variable lift the 2.0s get.

Probably 4k which is why I sold it.

Does it really suffer from slow spool, or is that the way APR has the tune set? Stock downpipe maybe? I don't quite get why a small BB turbo would spool slowly.

A lot of things will impact spool. Tuning, lack of DP, yes those. Also design and components as well. I suspect the issue is probably the 9 blade turbine choice. But I'm no turbo guru.

the percieved lag isn't THAT bad, but it is no is38 thats for sure.

the worst of it is when i need to, say, cut across a busy intersection. if i don't launch the car i become scared i'm not gonna make it across lol

That sounds amazing - great to live with on a daily basis.

I can’t speak to your R with fueling upgrades. On my GTI it’s a hair faster than my stage 1 on the low end and gets reckless on the high end.

Yes, @Daks is faster, but I’m way ok with that.

Yeah but how much of that is gear/mode dependent?

I found that in D mode on my stage 1 R I feel the same way crossing traffic. I've learned the car scoots way faster from a stand still in S mode. I toggle regularly from D to S depending on anticipated acceleration.

You know that I may actually be slower right? I'm just typing shit on the internet. But one thing I do know is that my torque curve is leaps and bounds better.
