Ok - got my UOA back that was actually BEFORE the track UOA - AL went from 3ppm to 5pmm, Iron went from 3ppm to 4ppm.

Silicon (contaminants) was up a little. Curious - what is aluminum in our motors? Will post the actually UOA soon

 

head, pistons, bearing material? don't some oils have trace amounts of certain minerals in them already? i never send oil out, so i'm not too familiar with the process LOL.
just trying to get my learn on.

 

Here it is!

 

back to the subject of awesome WW IX MRs, after swapping the new turbo onto my car, the thing drives absolutely amazing. the boost is damned near like stock. i forgot what it was like to have a car put me back into my seat. i took off from a stop sign at a reasonable RPM and it spooled up fast enough to spin the tires. my old turbo either bogged or i had to slip the clutch quite a bit. it did NOT leap off the line like this.
i think i'm in love all over again LOL.

i can't wait to see what it does with another 3psi and e85?? oh, muh gawd.

 

probably a lot going from 91 lol

curious about a 20-60 pull in 2nd gear if you've got one, and a 0-60. As far as what I've got measured for 0-60s from starts at autox, I think I'm right around 4s or quicker

 

i think the increase on my old turbo was about 80whp! probably close to that now. crazy.

i can get a 20-60 log for you. as for 0-60, i'm not good at launching the car, but that sounds too good to pass up LOL.

i get the car back from paint on Sat or Sunday. i should be able to do it Monday. the car isn't tuned, but it will give you a reasonable idea of what it's capable of.

 

no rush, you can wait til it's tuned.

best thing to do is mount a camera somewhere the tach or speedo is visible, count down and take a video of the run, and upload it and try about 10x with the stopwatch and get some kind of average

 

We'll see how it goes. I have no eta on getting it tuned, so if it's going to be a while, I'll try it as is. At lighter loads, it should do just fine, I'd think.

 

Aluminum is pistons and bearings. Silicon is pistons, iron is the block.

I would say those contaminants are coming from the Pistons and bores. Numbers still aren't high though.

Also, the one with low numbers had .5qt top up, which will dilute the contaminants.

 

True, good point.

Will run another test in the spring with a Purolator Pure1 & same oil, then a new oil I've got in the pipelines and the filter of my choice.

 

morning session over and the car feels pretty good. tires are totally toast but I've gone from about 17 clicks from stiff to about 13 and the car is rolling less and is more neutral than before.

I'll continue cranking up the clicks just to finish testing but otherwise I think the car feels ok. what I'm gonna do I think is stay on 8/10 and switch tires at the start of the year, and run on these rates with the new tires and decide then if I'll want new spring rates.

I may swap the ohlins springs out for swift springs just because though but as of right now, it's ok. weight transfer is less extreme and roll is more controlled. something still feels off about the car.. I'm definitely not as fast in it as I'd like to be. I'm honestly probably only 1s off of my evo in my mini

 

So a few conclusions from today:

1) Tires make most of the data inconclusive
2) Stiffening the shocks generally resulted in less body roll
3) ACD tune doesn't necessarily make the car LOOSER, just turns better

Here's a summary of the runs I did today:
Run Shocks Notes
1 17 All Around Spin
2 17 All Around Drift
3 17 All Around Clean
4 17F 16R Spin
5 16 All Around Spin
6 13 All Around Clean - less roll
7 13 All Around w/ Passenger, Clean, starting to understeer
8 13 All Around ACD Mid, Clean - 47.018
9 13 All Around Near spin, missed gate
10 12 All Around Near spin, missed gate
11 12 All Around Car feeling better
12 12F 11R Car felt good - 46.754, fastest up to that point
13 10 All Around Car bit me
14 10F 8R Car bit me
15 9F 8R Looked decent
16 9F 8R ACD Mid, Clean - 46.462





So, while the shocks resulted in less overall roll and general instability, the car would still bite me from time to time. Granted I was changing shocks every run, so I don't know how focused I was on getting a good, clean run in. The car is:

1) Understeering in tight corners, decreasing radius areas
2) Perfect in sweeper/fast entrances
3) A little loose in slaloms
4) Totally loose in transitions where, car is loaded up on one side then needs to change directions

#4 was 99% of my spins today. I'd be loaded up making a left sweepy turn, then needed to make a quick right - would turn, and the car would spin out. I can't say from this that I want to go stiffer springs. The 8/1 felt okay, I just need more grip I think. I may still get Swift 8/10 springs from MAP, and maaaybe pick up 12s too just to test later, but it could be that with grippy tires the car feels perfect. Obviously the car won't feel perfect in every corner, just need to get it in a good place. Overall kind of odd how loose the car is for autocross. Evos aren't exactly known for being loose here

 

And one oddity with the LCD in the odometer - hit a hard bump and it's like the LCD fluid splashed or something... I couldn't ready any of the numbers in the odometer, every possible area in the "8" was filled out. Eventually it dripped back down to wherever it came from and it's totally normal, but it was weird. I only caught a pic of it as it was leveling back off, and then after. Note at the bottom of the first pic where it was draining back down into or something. Odometer was totally illegible before that:

 

That's how my how my car was when bringin the dampers to nearly full stiff, it would try to bite me on the hard/fast transitions. The stiffer I made the shocks the better it would get, until I noticed it getting skaty, so I backed off one click and left it. So for autox I run 4f 2r clicks out from stiff, and I soften it 4 more clicks all around when I head home.

It could also partly be your tires. I'm willing to bet slow speed lack of grip and decreasing radius issues is more the worn tires.

 

a little confused - your car was like that when bringing it to full stiff, but the stiffer it got the better it got?

and yea I crank all the way down to 5 clicks from soft driving home, it's a pleasant ride. I'm really thinking an FSB would be a nice solution here, but I'm nowhere near ready to take that on.
