So whats the point of me posting dyno numbers if they're just going to be discredited? Not worth my time and money if it means nothing.

Noone here has my level of mods on stock K16's. We are in uncharted territory.
I will dyno but not sure if I feel like dealing with the headache of posting it here.

I know my 18G billets are only supposed to flow 43 lb/min so I don't think the 16's flow that much.
Bernard I'm again talking turbocharger flow. New gen billet 16g from blouch is a 41lb wheel.

you can't compare turbos from 5-10 years ago to stuff today. Tech has come so far it's crazy. Even a billet wheel to billet wheel of the same size. One from today very well may flow 5-10% more air than the old design billet wheel from 5 years ago.

I'm talking with what currently availbe produced today.

I'd guess you're getting 15-20 hp from the intake mods, certainly there is even more benefit lower in the power range that helps the car pick up faster that would be really noticeable. That's pretty good for intake mods though, HP is hard to come by without using tons of boost or porting out heads with cams and stuff like that.

Ok, then it would be fair to compare the new 16g to the old 18g, which has done 730 wheel hp or so.

Catless and mufflerless 3" exhaust picks up a bunch. Blowing through 4 mufflers is a restriction any way you look at it. 4.5" intercoolers with proper 2.5" plumbing and not the restrictive "bolt-on" style end tanks also pickup flow.
The filters on turbos made the biggest "feel of pants" difference on my car to date. The difference felt ridiculous.

Here is another example of turbo tech coming a long ways. Here is the 71hta comp wheel.

the inducer is .7mm larger than an 18g and 1.3mm smaller than a 20g with the same exducer size as both. It flows 51lb.

Nice. Is there any tradeoff for spool up time?

was that cast or a billet. A mhi cast 18g flows about 39lb. So a modern billet 16g out flow a cast 18g by about 5%. Looking at something like a cast 20g, they flowed 42lb. Modern billet flows over 50lb.
billet to billet it can be hard to say as it harder to find maps for everything.

it would spoil faster. More efficient design as well as probably lighter than a cast 18g or 20g.

Here is any example of technology. This is garrets 3071 gtx wheel, gen 1 vs gen 2. You can see how much flow is gained. Same size wheel, just better design

I agree, I think dyno would just get people arguing more. Unless it was a known dyno where some other cars have posted up numbers to compare.

I'd rather see some 60-130 vbox numbers. To compare with the other 60-130's listed on here. Even that would probably not be argument free but it'd be cool to see some solid 60-130's from your setup.

No ones arguing you said you can make 530awhp on stock k16. So we all wanted to see it. 60-130 will be around the 9s with stock turbos on a tune.

Take a video with the speedo of you flooring it then we can tell better.

Does anyone near BauerR have a vbox they could lend him? I think seeing a couple (2-3) consistent vbox runs would really be a great barometer here. Honestly, I believe that would really be the best bet.

Lol level of mods? You have intercoolers, y pipe, TB and plenum. Those mods make a tad of hp if any on those stock k16s.
