did I miss a thread?
any experiences?
I would consider touching any load maps won't help me improving WOT.
It also seems that narrow band Lambda sensors were used deep in the latest decade.

thx in advance

5 minutes for 3hp

YAY!

I read somewhere that Integrated Enginering made a custom set of cams to convert the 1.8t to NA. I cant find the link though..

Did you not get a naturally aspirated 1.8 20v in the US then?

In Europe we got the ADR 125 BHP (I think) 1.8 20v NA engine.

Volumetric efficiency. The limiting factor is the amount of air you can get into the cylinders. Without a way of increasing that, the best you can hope for is optimizing power output.

I suppose by altering the cam changeover and the hardware you can increase efficiency, but the results will pale in comparison to forced induction engines.

In short, advance the timing to the limit (based on the available fuel) and give it some fuel. I'm sure changing the maps relating to pedal/throttle body could make it FEEL faster, but I doubt that would be worth while.

This is all my take on it, YMMV.

EDIT:

I should note that this is all based on tuning an otherwise stock engine. Obviously optimizing the tune for hardware changes will be more beneficial.

Because the N/A tuner community thinks 3hp is amazing.

Yes first thing would be a cam change because the 1.8t cams are for forced induction only.

Inertia supercharging is a way to get more into the cylinders. You get that with cams that implement  alot of valve overlap and high lift.

Need high compression, 11 to 1 max on pump gas.

I bet you could manip the maps for the vvt in your favor somwhat like the ricers do with their vtec.

I think a N/A  1.8t with stock cams would make like 40 whole hp lol realisticly.

thanks for your opinions!
N/A engines seem to be a lot more aggressive in their OEM KFZW to gain some HP.
It's obviously a matter of dyno effort to get some handful HP, may be together with a good exhaust and fuel.

Adding timing, reducing knock enrich, and giving the motor the fuel it wants rather than relying on an EGT model is good for 15-20BHP on the N/A 4.2 V8s that use ME7. There's definitely gains to be had.
