Not seeing the gain I expected. :-( What's going on?? **solved**
To avoid wasting anyone's time, I copy post 18 in here:
Quote:
I did 4 pulls today on as perfect flat road as they get - 2 in each direction. I loaded the logs with Virtual Dyno, compensating for IAT and ambient pressure as read out from the logs at 4000 rpm. Compensated for wheel size (own measurement) to compare with my old logs (winter wheels). So here are the results: - Red, blue, dark green, yellow (first 4, are todays pulls). This is with a Gruppe S header and Wayno's most recent stg 2 tune and OFH timing. The light green: - A bit unreliable from when everything (incl tune) was stock but the best I have and fairly similar shape and number as an actual real life dyno pull I had made during a dyno day. Here is the bummer: - The purple pull is one of Wayno's most recent stg 1 tunes, with some extra timing. I don't think that it's more power than some of todays pulls as virtual dyno suggests. But just the fact that it appears to be in the same ball park I find truly disappointing. I was expecting a 10 hp gain from installing the header. While the 4000 rpm torque dip improvement is nice, I'm not sure I think it can be right? Butt dyno says there is more power obviously especially in the torque dip. But now I am starting to doubt if the rest perceived improvement is placebo? I'm a man of science, I tend to believe more in number than feelings. Don't know if it's screwing up because of the wheel sizes? The old pulls where with AD08Rs in 225x40R18... Todays pulls with stock Primacys 215x45R17. I'm close to putting the AD08Rs on to see if it makes a difference, though it might not be the best idea with temperatures below freezing at the moment. If these are indeed true numbers, the header is being put up for sale! Edit: Here are the logs in datazap (3 logs): http://datazap.me/u/tor/ft86club No IAM drops in play or otherwise strange. As mentioned IAT taken from 4000 rpm and pressure from an average of the highest and lowest in the logs, wheel sizes 24.88 for the old pulls, 24.6 for todays pulls. 2769 lbs weight for the car and 165 for the driver.

I can't... Living in Germany. It's fucking monopoly here.
There are only 2 legal kits. A turbo and HKS, and they can only be installed by one of the 2 companies that provide them respectively. Naturally they charge a shitload of money. Converted 8000$+. No fucking way I am going to spend that much money on a car that's worth 15-20000$. Then I'd rather buy a Porsche.

Technically I'm not even allowed to swap the header.
But a header I can swap back in 30 mins every 2 years when the car has to get it's mandatory TÜV inspection. I'm not quite sure about the orgins, but I think they introduced TÜV in the 1940'es.

So stock was 156 hp/170 Nm, and pull 4 was 175 hp/190 Nm with a catless UEL header and tune. You gained 19 hp/20 Nm overall, and a lot more area under the curves. I'm not sure I understand the problem. Most UEL headers and tunes will get you in the 175-185 range. If you want to push 200 hp you need one of the nicer EL headers such as PTuning or ACE. Or go with E85, but I don't know how feasible that is where you are.

You can also use E85 to lower your emissions if necessary and E85 gives you a nice bump in power also.

Sure there is under the curve improvements but only below 5000 rpm. I track the car, I was hoping to see improvement on the top as well. I was hoping someone would post that Virtual Dyno is shit, but seeing the consistency between pulls I don't believe it can be discounted totally. I don't want it to sound like I am bitching. Rather, I just don't get it! I run 5 deg more timing up top. What's wrong here?? Also, I am not bitching about the tunes. Rather I'm surprised how good and sorted Wayno's most recent stg 1is. If it outputs similar numbers at the top with 5 degs less timing that's truly astonishing. The gained torque in the dip is nice, but I'm not sure I'm going to bother putting it back on next time I have to take it off for TÜV inspection. Quote:
I seriously doubt the 200 hp claim of the Ace headers. That's nice marketing from CSG. Probably they are max 190. 5 hp more wasn't worth more than double the price for me.

Well I will only be selling one header. And because people here are scared of ordering overseas I could probably sell it with a profit even after using it a year until the next time the car needs inspection and I have to take it off.
