Will probably be faster now that there will be less wind resistance

Ok I am still battling my brake feel issues that I need to troubleshoot, but some good news came in from the latest oil analysis.

Around 4800 miles on the car now, but the oil is looking great. I think I am going to continue to run the Castrol GTX 20W50. I have been changing the oil in the pan every 2 track days. I have been seeing some oil temps in hot weather that we're starting to give me concern, but clearly the oil is holding up with my current change intervals. This sample was from 2 track days where the temps were above 95 degrees. Oil temps in the pan hit 270 F when it's that hot.

An update for 2016.

I had the car out at Willow Springs yesterday, and overall had a very good day. The brake issues I was having are now resolved, so I can get back to where I wanted to be 3-4 months ago and make the car faster. I had ran my personal best at Willow almost exactly year ago, and that day was nearly ideal conditions. If you have been following along, there have been some changes since then, mostly around spring rates and tires and I have been hoping to see what kind of improvement I could get out of myself and the car. Aside from  20-30 MPH constant winds, conditions were again ideal. It was about 60 degrees, sunny, but mild.

I did lower my personal best time to a 1:33.9 with a mistake coming out of turn 3. My rolling lap time from turn 3 to turn 3 was 1:33.4, which is right where I caught the s2000 in the end of the video below. I think the slide may have cost me closer to a full second in total had that s2000 not been there and I got through turn 4 cleanly. Plus the headwind shaved off about 6 MPH on the long front straight. Considering all of that I am very happy.

In looking at the data, I am getting out of every corner faster, and getting back to the gas sooner than i was previously. Yesterday I was more conservative under braking and corner entry than usual than due to the wind, and that showed in the lap data.  I have a pretty good handle on the new setup and the pressures the Maxxis tires like to be run at now. As Joel will tell you and you can see on the previous videos, the car was a lot of work to drive fast, and I spent a lot of time waiting on the car before getting on the throttle. Now there is some more consistency and the times are even better, so I know there are some gains yet to be realized as I push harder.

And a couple pictures of the car as it sits in its multicolored state. I will be working on getting the hood and fenders painted pretty soon. I really don't like how crappy the car looks, but people take the car even less serious now than when it was all red. After every session several people come over to see WTF is going on. Lots of amazement that an old POS looking car is that fast and/or passed them. I met a couple guys that followed the build here or have seen me post on the club who were pretty cool as well.




Issue report:
My Accusump seems to be working intermittently. I think it is a known issue with the coil on the valve, I will call Canton tomorrow, and it should be an easy fix to swap the coil on the valve.]

My ignition switch is going south and running the starter when it is not supposed to. This looks like another pretty easy fix to swap the switch electronics.

Passenger outer CV is still venting grease when it gets hot. I have no idea why, I will have to pull the rear hub and check it all out back there.

The type of grease can make a big difference.
Try a higher boil point grease

Agreed.I have some NEO CV grease to repack them with if it comes to that.

The weird part is that the CV boot is vented. The grease is not even coming out of the vent side, it is coming out of the large stub axle side and flinging on to the inside of the wheel. The left side did this once and I vented it and it has been fine ever since. I am wondering if this right side has too much grease in it.

Good stuff Ash! 
I definitely recommend changing grease to NEO and too much grease will sling worse.  I put about 6 oz per boot and use the wd40 straw on the small end of the cv. I  re-pack them once a year during my winter re-fresh.  :cheers:

Thanks Erik. I will get it figured out one way or another. I have to take the rear hubs off for some service and modifications anyway.

you should go fancy and drill all the way through your halfshafts and diff stubshaft and vent through the diff breather.

Worked on the car a little bit and have my starter issue diagnosed. I ordered a new solenoid for the starter. I also got the nuts for the halfshafts broken loose so I can pull off the rear hubs for service and new PBM solid upper rear upright bushing I need to press in. I had to take the car down the street to the local tire shop to get the passenger nut off.. I broke a Craftsman 1/2 extension trying to get it off with a breaker bar. The guy blasted it off in 2 seconds with his impact gun. Now I need to go to Sears to get a new extension.

I have one of these.  6:1 reduction on a 3/4" output.  I reduce to 1/2" but always use impact sockets & extensions.

Yea it was my bad using the Craftsman extension for this. Oh well.. Sears is right next to my office, so it is not a huge inconvenience. I was going to fill the compressor and try my impact, but I do not have a 32mm impact socket. The quick trip down the road was worth it to get it off at least.

 I should buy one of those reduction units.. pretty cool.

Have you done more research on grease?  I know in the offroad world they use this stuff and it works great.  http://www.kartek.com/parts/bel-ray-anit-seize-cv-grease-compound-123-lbs-grease-gun-tube.html?Session_ID=c2468b0517b8588bd29ae1c30bb5c5ae

I have some Neo CV500 grease that is good to 1200 degrees. It is about the same price as that Bel-ray grease. A lot of off-road racers use this Neo product, or the one below.

They also offer HPCC#1 but it is around $60 and offers better protection in extreme temps, which I don't think is needed in this application.
