How's your timing map running 28/29psi through the HTA71 with only 91 octane available? I will have to go back and adjust the preload as I like your WGDC numbers way more than mine. I also need to figure out what I did wrong with V7 so I can run gear by boost as well. I don't know how I'm going to fall asleep tonight as I haven't auto-xed in 5 months and I'm giddy like a schoolgirl.

 

Well I had a super humbling day at auto-x. Nothing broke, which was nice, but it was a really tough day. I had an idea in my head of how the car would handle with all the new parts and it definitely was not what I was expecting. I started the day with the rear bar on medium which ended up spinning me in a slalom. I put it on medium/soft which felt better but never went to full soft.

I was able to achieve mild power oversteer with the diffs but as soon as I let off the gas it was straight back to ungodly amounts of understeer. I wish I hadn't done the front and rear diffs at the same time as I feel like the amazing amount of grip the front has masks the extra lockup of the rear. I only got one good run in out of four. There were 188 people at the event so I didn't get as many runs as I was hoping for. It's amazing how different the car is. I couldn't predict it to save my life and the extra power only made matters worse as everything was coming at me faster which meant all of my inputs had to be more upsetting to the car.

There are three events next month and I'm not changing any of the setup between now and then. I need to relearn the car and verify that it's truly spring rates that are holding me back. I have the tire, I have the power, I have the brakes, but I don't feel like I have enough spring to put all of my tires to good use. I've always known that my GTWorx/Bilstein combo was light on spring and was holding me back but now it's readily apparent. So, upon verification, I'll be throwing some coilovers at the issue to hopefully cure the chronic understeer I have. I did ride in a friend's STU STi with ZIIs on it (245s as compared to my 255s) and he was fighting grip the same as I was but he didn't have the understeer issues. In a rare showing of emotion I let my performance affect my driving which didn't help anything. I ended up 45th out of 188 in raw time which bumped to 82nd in PAX.

I also found a couple of issues. When I hopped in my car I noticed my clutch pedal had almost no travel. I thought maybe the lock nut had loosened up but it hadn't when I checked it. I pulled the pedal up and while regaining full travel my engagement point had moved up drastically. I didn't launch the car as I was the only one in SM so I saw no need to beat the car for no reason. The clutch didn't give me any issues during the event but on the way home the clutch pedal did the same thing again, almost no travel. Also on the way home I noticed that with the cutout open I wasn't hitting full boost even with error correction on. I've got a couple of weeks before the next event and will be working on the clutch pedal/wastegate issues.

 

Just saw this. Im running 0 deg at pk tq and 13 up top. Really get on the timing ramp around 5500. Slight sporadic knock on spool up, but clean everywhere else. Now its almost the same timing I was running at 23psi on the VIII 10.5 turbo.




Too bad about your 1st venture out with the new setup. But at least you got it out of the way. Im glad I went ahead and splurged for the coilovers this year, as I feel that was my biggest improvement for a/x. Im sure if you just dial back the right foot a little, it will pick up time. Its amazing how slow=fast most of the time.


Good luck with the clutch. Bleed it and also check the floor mat area for leaks from the master.

 

Do you ever autox in College Station with TAMSCC? Just curious.

 

Aggie - Yes I auto-x in Bryan with TAMSCC. You going to run there sometime or just wondering?

I don't have any updates as I went up north for Memorial Day weekend so it was really hard to work on the car.

 

I did a few times when I was at school there. Haven't been back in forever. I'd really like to when I get everything sorted out.

 

I think I just found some of your YouTube vids while looking at Texas autox Good stuff!

 

The videos should only get better. They're posted by donkey_518 on youtube. I also might have just bought some AST 5100s from a member here. Hopefully I can get them here, installed, and corner balanced before next event. So much for not changing anything. I've always known my suspension wasn't enough so I said screw it and dropped the money.

 

sweet! what rates?

 

Starting out with a square 12k setup. I am also getting a pair of 10k for the front if I wish to use them.

 

Are you still running the Bilsteins and GTWorx now? Lemme know if you're selling them

 

Aggie - Yes I'm still running the GTWorx/Bilsteins/Tein camber plates at the moment. I will be selling them and there's already some local desire for them. I'll PM you when the time comes closer. Plus I think I'm going to go to EvoD to corner balance and align the car so I may be up near you in the next few weeks.

 

Sounds good. We should meet up either way.

 

Do you feel like the 16 plate weir kit would be too aggressive? Was the 12 hard to install?

 

Tunah - The 12 plate wasn't hard to install and I can't imagine that the 16 would be that much different. I went with the 12 due to the warning about the 16 being super serious performance based. I don't daily my car but was trying to keep aggravating noises to a minimum.

Aggie - I'll get a hold of you.
