Ok, I have them installed, not the only one here, I have not given a review because the car has not been fully mapped by Henk.
They went in a fit perfectly, so that is one important thing. No problems there. Second doubt is about the quality of fabircation so first thing to check was hardness, I tested them and the lobes are 55RC so they do suit the job. The other concern related to the quality over all would be durability, but there is only one way to find out at this point. I have had them in for about 300 miles so there is no way to report there. However, I checked and the cam shows not a single mark at this point, which is expected, as some said, if they were made from cheese by now they should be at least color marked. But as said, no way to report on that with only 300 miles
To the way she drives. They give an erratic idle, I am really picky and that was an "issue", henk has sent me a second version of the map and bettered a bit, but by no means will be close to stock. It idles at 1100. There is a video of a 182 with colombo at fire up, well, look it and you will see what is like, as they are same spec and my car does sound the same as the one in that video.
Low down power delivery is... not smooth, the car doesn't like the 1 - 2K range, some will say I am being gay, but when you drive in a 22million city... well, that is where you are 60% of the time, think of drving around London's downtown if not worst. As soon as you pass the 2K mark it is very close to standard, at 2.5K you feel there is more than before and so it keeps to 4K where the engine comes to live and pulls really hard, you really feel the difference. I have race another mate's 172 and I was faster off the line and on the roll test I was also faster, so as long as it is over 2K rpms there is more of all all the time, get caught lower and you fill like driving a 1.2. The car likes pulling all the way to the redline without the vanishing feeling beyond 6.5K and crashes on the limiter with anger.
The other thing I noticed is the tappets are noiser, not in a clunky or metalic tapping way, but sound more like an injector due to the higher lift, or may be they are the inyectors. So the idle is a bit crappy and the delivery very low down is the trade off, but I think they are a "good" compromise for the gains. Next will be how best it gets once the map is complete and how long they last, the stock cams came out unscratched, only visual marks from the journal contact but by touch you can not feel them, only visual. Hope these last as long (70,000), if so, they have been a very nice purchase.
206hp, don't know, I will measure it once it is completely mapped, as referece, mine did 150 to the wheels before cams. Will see how much it does afterwards.
