Very creative. Would love to see how it goes.
So, you replaced just the UIM and IIM right? Still have the stock LIM w/ the secondary injectors?
Ported? I would love to see a dyno too.
Also, why shifting around 5k? I know mine winds out to 8k before I need to shift, and it pulls the whole way there.

Na
um how are u going to be pushing 265 on a stock na. Also unless u switch out the internals of the s4 to a s5 you are starting with 146 hp not 160 like the s5 will have.

Yea, I thought that is what he said on the video too. Thought I misheard.
realistically 265 isn't going to happen. Shoot for about 180 or so. 200 if you get a really good tune, and have some porting.
You should get a dyno done, and see what you have now. I would probably guess 130 or so at the wheels. A big part of the S5 was the VDI which added a significant amount of HP. The S5 internals had a bit higher compression, but nothing that adds an insane amount of HP.

so true thanks for agreeing wit me. I have done so much resarch on the stock na and the most any has pushed was 200 with out doing a port job. It is a shame you have at least done a street port. That would have given you a little more power without losing low end like a bridge or higher port. But still looks nice i like ur intake guessing u made it ur self?

I'm sorry to be the realist here, but I don't see that car making much over 220HP, if that.
I think your manifold runners are way too short and the monster loss of low and midrange torque as compared to the S4 stock manifold may make the car slower then it was before. Putting an S-AFC on the car (it is not a "management system", it is a "piggyback fuel controller") is not going to make 265HP even with that intake. While I would think the intake may show some gains up top, did you calculate runner length? If so, where does it resonate? I suspect you will find it's around 10,000 RPM where it comes into it's stride assuming the aux ports are tied open.
Maybe I misunderstood though, because the voices on the video were very low. It sounds like a stock port engine...
