Do you have extra head studs on your engine for the boost?

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

that ROCKS Wally

Congrats Wally! Awesome results! It just keeps getting better! Torque just shoots straight up 420NM and only 16psi - fantastic!

I wonder what my 2.8 build would put out turbo'ed?Hmmmm.

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

Congratulations on your 350hp aircooled daily driver

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)

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?

I didn't say and never said that its daily driven... its not

Its also not 'just' street legal. It has the (turbo) power on the official vehicles papers! Furthermore I do track days, runs several laps Nurburgring (15 miles for just 1 lap) and drive to all european drag day events on its own wheels and in germany at sustained speeds of well over 100 mph on the autobahn.
So the car has a worse life than when it would be daily driven
