Nope, just good ones (ARP) but it only has 16 psi at 6000-6500, so its not excessive boost that created these hp numbers
And on a 103mm bore, which is said to not even seal in n/a aplications...

And cast alu cylinders, stock VW type4 crank and stock rods.

I count at least another 3 myths busted

Good looking numbers! hows the seat of the pants feel between the different turbos, any noticable difference besides lag?

When you say your car is daily driven are we talking like a 40 mile round trip to work 5 days a week or its just street legal?

Funny thing is, there is just 100-150 rpm lag difference! So its hardly felt in real world conditions.

I overlaid the two dyno plots and this turbo is about the same down low, but just keeps pulling more (more torque) from 4500 rpm to 6500 rpm, while the former turbo did not make more power after 6000 rpm.
But I only did two evenings road'tuning' with it, that was it. So there's probably a little more in it I suspect (but not that much)
