I have an Autotech intake and a VWR turbo inlet pipe in a box waiting to install. It should fit fine, I'll let you know for sure next week.

Anyone ever dyno before and after? My money's still on there's no gains regardless of which one you choose. I've seen the flow bench data, I'm still not convinced cuz it's still bottle necked at the mouth of the turbo
I don't think it was posted on here, but Kevin from ESP did a back to back dyno with the stock and cts (I let him use mine) on a stage 2 UM gti and picked up ~ 10 HP throughout the range. This was done on a mustang dyno (my car did 208 whp/228 ft lbs stock there). He posted it in the Facebook group. 10 HP is pretty marginal since run to run can vary that much- so take that how you may. He did 3 runs with each and picked the highest of each setup. All 3 cts inlet runs were higher than any of the stock inlet runs despite being run while the car was still hot from the stock inlet runs.

There ya go fellas. Gains.
Awesome! I hugely appreciate that as I'm expecting my Autotech in the mail this week as well.
AWESOME!!! Which one are you using, is that the CTS?I do. Fits perfect!
I'm not going to flash my car any time soon if ever (even selling my Eurodyne PowerTap flash cable), so all of my mods that add any power will be the old school way of hard mods lol. I don't want much at all because I really enjoy the stock power on the street (I've had tire shredders before, but always been a fan of efficient power over brute power). If I gain 10whp total, I'll feel pretty good about that, if not, I'll still feel good.
Wish I could install a DP without worry of something being damaged, that'd be a no brainer mod for me.

Nice, that's exactly what I was looking for. Probably not very notable but at least a measureable gain

It's overall dia. Regardless of how big the TIP is they still all taper down to the same size

At least we have some 3rd party data for a stage 2 car, good to see. Would love to see a stock dyno before and after and then we could extrapolate the curve for stage 1. All l have been saying is that putting this on a stock car is not going to yield the same benefit. An educated guess would be 2-3 HP stock, 4-5 HP stage 1, 8-10 HP stage 2, 11-13 HP stage 3.
As VWR astutely explains: "The higher your power level, the greater the benefit. That’s why the VWR High-Flow Turbo 90 is included in our Stage 3 upgrade – we simply can’t get to the power levels without it."
If stock, you will NOT gain 10 HP by adding this part. Gains will be negliable. Moving from 91 to 93 octane fuel will yield more HP. Seems promising for stage 2 and 3 cars though. The data so far shows this.

The stock, OEM TIP tapers down to a size that is smaller than the inlet of the turbocharger. This is the bottleneck.
The aftermarket ones are the same diameter as the inlet of the turbocharger through the entire turbo inlet pipe.
This restriction is enough to cause a slight pressure drop which eliminating would allow people to shift towards a higher efficiency operating zone on the compressor curve.
However, I do not believe anyone has the IS20 or IS38 compressor curve.
