TD header, tune & afpr question

I use a dog bone, extension, ratchet and torque wrench. Also put nickel antifreeze on threads.
 
You're welcome to drive west and we can put your SW on the track dyno, @Turboflash will tell you you'd likely learn alot.
Tell us more please.
I have used a dyno prior for diagnostic tool, tuning tool and seating the rings on engines.
How close can the clutching setup be done on the dyno?

This past weekend I had an intake temp sensor acting up and showing from -40f to over 400°.
When it was in an open condition it would show the high temp and throw a sd 22 code and go to a fail safe condition.
When it was in a shorted condition it would max out at -40°f and go pig rich, burble and shoot flames out the exhaust.
Have data logging and was able to see what was going on on the logs.
New sensor is on its way.
 
Bad intake air temp sensor...
This did not set code.
Had to have a longer duration of open to set code.
Every time a drastic change in air intake temp would happen the timing would be pulled slightly on the knock sensitivity.

How many miles on the sled?
 
North of 13k
Not that many really. Good to find it though. Seems like we see some random failures on these along the way. Not to bad really considering. I lost a crank sensor a few year back with half of what you have. "they don't make things like they used to" .
 
Data logging...
who needs data logging....

Purchased the data logging last winter.
Didn't drive sled more than twice.

Got some runs on it this year and finding this issue looking at inputs and outputs.

Spend money buying tunes and supporting mods.
Have to see what's going on to get your money's worth...
 
Strangely enough, what I find extremely beneficial while data logging is screen recording my test runs. Later, I play back the test run live and look for any inconsistencies. If any are found, I revert to the data log graph and break it down to the 1/100th of a second to see what went wrong or right.

In addition, let's say while screen recording you break records, you can send the screen recordings to your buddies via text to rub it in!! Lol

I feel I can get you within 200 rpm on the dyno, the biggest thing is we can look at the acceleration rate and RPM graph and see exactly what change did what, much in the same you can with your datalogging out in the field, but when lack of snow or time happens, then our track dyno is very good. @Turboflash went through 98 runs total in about a 24 hour time (3 hours on Thursday and 5 hours on Friday, roughly). We gained 10 hp to the track from our first runs to our best runs on both pump gas & race gas.

Wow, that's awesome!
 
I don't flinch on price gouging, if I need it I need it. But sitting here looking at this small handful of fasteners for $38 has me pulling my hair out hahahaha.....

Ha, I remember the days of changing pistons 2 to 3 times a winter and sometimes a crank on the old triples.
Back then is was $100 a horsepower in the aftermarket world.
We are getting away cheaper....

But fasteners & washers are killing us. Lol. I make a bet, piece by piece a new sled would be 60,000 (exaggerated) but I think you get the point.
 
You must be buying titanium hardware....
That stuff is high dollar.
Don't laugh now. I do have some titanium fasteners in my sled...

To late!! Lol. 650lbs - .002oz = 650lbs.
Just kidding....
