CALLOUT: DYNO CHALLENGE EVAN , MOSELY and KIZDAWAY

[chunky]

Oh yay this is back and kicking again... So what started all of this was that the dyno tests were poorly executed. So let's stop all the BS and talk about why. Here is the graph:


1st run: Was a shakedown, ok
2nd run: Wasn't reved out all the way, but who cares. It made it's power, the torque curve shows everything. it consistently made 4-5 more torque across the board.
3rd run: Look, another 4-5 torque all across the board. This usually happens when the car is still warming up.

That was all the info I had at the time, 3 pulls were done, each one showed an increase of 4-5 lbs of torque, so why was there not a 4th pull? On top of that... the runs on mike's header were done open header. You can claim it makes no difference but that is just speculation. There are many reasons why unbolting the exhaust can affect the power levels of a car. Running open header vs. full exhaust just adds in more variables to the equation. So from my point of view, this was a bad comparison because...

1) Never seeing the SSR pulls stabilize into any sort of consistency
2) Running one header without an exhaust bolted up

That is all I was trying to say from day 1. I never said the tests were rigged so I don't know where all of that came from.

Lately there's a lot of reassuring that there was a 4th pull made but it was deleted for the purposes of building the overlay. I find that funny because there was never any mention of that 4th pull until I layed out exactly where the problem was in the SSR pulls. So here are all of the pulls:


You know what is funny? If Mike had deleted the 4th pull for the purpose of building the overlay, wouldn't RunFile_004 be missing from the sequence?

HP also picks up as IATs stabilize. IAT has a big influence in ignition. There are multiple scenarios that could result in power output increasing until things stabilize.

Regarding missing plots, if they're deleted before the next run is made, then the numbering resumes from the highest number present in the directory.

In my experience, I've seen zero gains on k-series motors going from 3" exhaust to open header for an all motor or supercharged car making up to 300whp. I tested this multiple times on the dyno, and I'm confident enough in it that I pretty much never bother tuning motors open header if they have a 3" exhaust. Otherwise when I'm tuning I'll do a few pulls open header to see what the max potential is w/o exhaust restriction.

I can testify that there were in FACT ONLY 3 PULLS done on the SSR header while it was still bolted up to the car. The last pull was the pull that made 194.

But anyways, that's all in the past and that's all said and done. I unfortuntately have began working the evening shift at work for the summer and have been swamped with getting into the summer groove at Conference Services. And as Mentioned before I only finished finals 2 weeks ago and now I am beginning to see where I will have time in my schedule.

If you pick a point some time this week we can get together and get this all finalized and sorted out for the last time so that everyone can be done with this.

Also funny things to note is the fact that the Torque spikes were clearly not tuned out of my header like they were supposed to be and should have looked more like the graph of the test header run... Which doesn't make much sense because the SSR Header was TUNED on that map, not the Test header.... and also a problem was recently discovered that has led to me only having 75% throttle this entire time. So... with some quick fixes and tweaking hoopefully everything cab be settled by the end of this... and we can just all agree on everything lol



Anyways Again I AM pretty much free for the most part this week so what days work best for everyone?

From the last time we spoke, I think you had mentioned that the tune for your SSR header left a lot to be desired. The throttle plate is an issue that should be fixed, but I wouldn't expect big gains from it. It's actually a common problem on k-swaps b/c there's no really good solution for the throttle cable bracket. Whenever it's fixed & the TPS is scaled properly in k-pro, the gains are minimal. The % reading of the TPS sensor is not linear, so 70% is really almost all the way open. Still, it's probably an easy fix and should be done.

I could probably make it there tomorrow in the afternoon....

edit: Luis can probably make it then too. Who else is coming and is tomorrow afternoon even available?

You guys are all adults you pick a time and tel me when and I'll set it up. Tomorrow afternoon is fine only times I canT make it are wed afternoon and Friday afternoon/night

but tonight, tues all day or night, wed night Thursday day and night are all open

I'm available tomorrow afternoon. Tell me what time and I'm there. Tomorrow will actually be a good day for me b/c I'm getting new wheels/tires mounted up & I'll probably be meeting up with matt earlier in the day.
