I'll be in the Lexus, Fred and Clu will be in their Miatas. Fred and I will be out there around 9am.

#111657 1999 Lexus SC400 - I messed up good this time

Posted by robertcope on 07 January 2019 - 09:53 AM

Well, I got the car back together this weekend. It seems to be working correctly now. ABS pump isn't running when the car is off. ABS seems to kick in when the brakes are slammed. We'll see what happens this weekend at MSRH!

#111469 Goals for 2018

Posted by robertcope on 31 December 2018 - 07:45 AM

I hope to get to the track some day. And get my Lexus running again.

 

I _did_ get to the track this year, but not as much as I had opened... only 22 days at the track, which is the same as 2017 and the lowest number of days on record. I'd hoped to make it 23 by going yesterday, but...

 

I did get the Lexus running this year! Running and even well prepared for the track! Yay. Ironically, as the year comes to a close, it is broken again!

My last outing, I had disabled the ABS because after the outing before that, when I got home, the ABS pump was running constantly when the ignition was off. The car was not very drivable without ABS; the rears locked up very easily, and in fact, I ruined a nice set of tires while making a lot of smoke! I put the car up on my lift and began trying to figure out what was going on.

 

It took me far too long to sort it out, but eventually I found the problem:

On the plus side, I have a very good idea how Toyota writes services manuals, electrical diagrams, etc now. And the damage isn't _that_ bad. Wiring is definitely not an area of expertise for me, but I think with a little patience I can fix this up.

Hi Robert, you going this weekend?

 

I don't think I'm going to make it out this weekend... if I do it'll be a spur of the moment deal. Next scheduled date is 1/13.

What are the respective lap times for each in this data? Looks like the NSX dominates on corner entry, which isn't very surprising, but they're neck and neck on corner exit. Makes sense, given a FR car gets super stable once you get it turned and on the power. I'm a little surprised the NSX doesn't use the tires a bit better under braking by having a more rearward weight bias, but I suppose there are a ton of variables there. 

 

Do you notice lines and style being very different between a FR/MR car? I would think Gut Check would favor the big Lexus a bit more by being a tad more stable there as long as she could turn in, but the Carousel likely favors the NSX due to the weight distribution and lower CG. 

 

If I'm reading it right, it seems the NSX was quite a bit better through Gut Check though? 

 

NSX runs is 47.5 or so, the Lexus is high 48s. I wouldn't put too much stock in the specifics, I don't drive either for it to be accurate, certainly not the Lexus which I've only had out a few times now. I think the two big gaps are the sweeper into bus stop and gut check, yeah. I would expect the NSX to outbreak the Lexus, but actually... the Lexus has Supra brakes on it and that was the best stopping car built for a number of years, supposedly. I think the Lexus will out perform the NSX once I've learned to drive it and done a bit of tuning.

With that said, gotta install the new shim when it arrives and get an alignment...then drive 5 hours to the track.

 

FWIW, there is a shop at the track and they do good alignments. I'd probably call and let them know you're coming if you decide to do that.

Is there a certain time we need to arrive at?

 

Track goes hot at 9am. It's open a bit before that. I try and arrive 8:30-8:45 so that I can BS and be ready to go. But you can arrive anytime, there's no driver meeting or anything you have to make. Unless there's a special schedule, bikes will run the top half of an hour and cars the bottom.




#111162 How to increase seat bottom cushion height?

Posted by robertcope on 18 December 2018 - 09:51 AM

This looks like it would work. Is it worth the $75 price tag?

 

This is what I made the bottom of my NSX driver seat out of. It's pretty nice and comfortable. Worth $75 is subjective, but given the overall cost of our hobby, it's below the threshold that I personally care too much about. I certainly haven't regretted the purchase.

I hope it goes to a good home that will leave it as is and enjoy it!

Did a few small thing today. Set front sway bars to heavy and rears to medium. Installed new trunk struts so that the trunk doesn't try and kill me anymore. Also put the car on scales on level ground and was pleasantly surprised at the perfect cross-weight:

Ever wonder how an SC400 compares to an NSX? I did. Black line is the NSX, green line is the Lexus. The obvious issue is the sweeper into bus stop (CCW) on this lap. I bet most of you didn't think it would be this capable :)

Took the car out to MSRH today. It did great. Here's a decent lap in it:
