Working on the rear end with @istoptofly. I had a nut broken off in the frame rail so he cut the T-brace off and then cut a chunk out of the frame rail to get the nut out and do the repair. He'll have to rebuild that section and then we'll be putting in his less rusted T-brace (with upgraded bushings) as well as an r180 and DSS rear axles.

The bolt repair is completed and the new T-brace, r180, and DSS rear axles are installed.

Here's an updated video. Changes since the last speedo video:

• Retarded Timing by 1 Tooth on Intake and Exhaust
• Enkei RPF1 17x9" +45
• Federal 595 RS-R 255/40R17
• R180, DSS 800HP Rear Axles

50-100mph (2nd, 3rd, 4th): ~3.5 seconds

Doesn't quite make it to 130mph, but it looks like 60-130mph would be the in 6 second range.

Here it is plotted out against my 10.9 @ 128mph log from Rock Falls last year.

My brother and I went out to Rock Falls today. I drove the car there and ran on the street tire setup. The car was run in full street trim and 3/4 to 1/2 tank of gas.

There were long lines in the staging lanes so it was about half an hour between passes. I ended up making 5 passes. I wasn't hooking up well and kept putting down 1.7s 60' times and 10.4 ET in the 1/4.

My best pass ended up being a 10.3s @ 139mph. It did 110mph in the 1/8th mile. Other than spinning a lot in 1st and 2nd the car did great and was feeling strong well into 5th gear.

I am hoping to be back again soon on slicks and maybe a little more boost and try for 9's. I think I have the trap speed to do it, I just need a good launch and the times should drop.

I have a few photos and videos from the day that I will try to get up later. My in-car camera didn't work but I have the speedo videos and my brother's track side videos.

Some better photos from at the track.

Best pass was a 10.3 @ 139mph.

Video from my 10.3 @ 139mph pass today. Spins through 1st and 2nd.

Here is a plot of the datalog from one of the passes.

0-100mph: ~6.1sec
50-100mph: ~3.6sec
60-130mph: ~6.1sec

Here's the same plot compared against my 10.9 @ 128mph pass from last season.

I got an alignment this week and during the alignment it was noted that one of my calipers was leaking fluid. I decided to go with remanufactured calipers, new rotors, and StopTech Street pads. I also picked up a vacuum bleeder to bleed the fluid after.

Old vs. New

Old pads had plenty of meat left but were developing a lot of cracks.

The removal and install went off without any problems. All bolts broke free without any issues. I put it all back together and went to use the vacuum bleeder. I started on the first one and it was pulling a small amount of fluid but 90% air. This went on for half an hour or so while I hoped it would get better. I was poking around trying to find a leak somewhere in the system but I couldn't find anything.

Then I looked online and found other people have had similar issues if the bleed fittings leaks around the threads when loosened. This is exactly what was happening to me. It was just pulling in tons of air right at the fitting even thought fluid was filling the lines all the way back to the caliper.

I'm not really sure how to prevent this. Maybe thread sealant on the bleeder fitting? I ended up enlisting my wife to push on the brake pedal and did it the old fashioned way. That worked without any problems because it pushes air out via positive pressure instead of pulling it out through the fitting.

I have had ongoing issues with the coolant overflow reservoir overflowing on high speed pulls. It wasn't a lot, so I don't think my heads are lifting, but it was enough to be noticeable. It was using the small coolant reservoir that comes with the eBay FMIC kits. It is a small cylinder.

The Treadstone FMIC kit comes with a larger, rectangular overflow so I got that out and mounted it next to my slim battery. I dumped the nearly full cylindrical overflow into the new one and it barely filled it (maybe 1/2" - 1" from the bottom. I measured the dimensions and the cylinder has about 25 in^3 of volume and the new one is around 72 in^3. So I should have a lot more room for expanding coolant. I will see if it helps...

Coolant overflow.

After I got that buttoned up I went and did half a dozen 50-5mph hard stops and then some more driving to cool it down and a couple 3rd gear brake boosts. The brakes seem to be working fine (the other ones seemed to be working fine too, but I believe they could have failed eventually due to the leak).

I've had various people comming on the stopping power from stock brakes (not just you), so I made a video. I will considering the larger rears once it's time to replace them, though.

Here's an extended cut of my 10.3 @ 139mph pass from Rock Falls last weekend. For anyone concerned that stock brakes aren't enough stopping power check out the video.

It is ~10 seconds from 140-40mph and another ~10 seconds cruising at 40mph before turning to head back. Probably no more than 1/3 to 1/2 braking at any point.

Yesterday Nuke and I took my car to do some dyno tuning at MAP. Since the last time at the track we switched it to an EBCS to be able to ramp up boost at the top end, and also put in a Boost-A-Pump because it was leaning out with the higher boost levels.

The car ended up making 666 WHP at 35psi, but we were seeing spark plug blow out on anything over 33 or 34psi so the plot breaks up at the higher boost levels. You can see the car spitting flames when it misses in the video. New plugs should be going in tonight.
