    Mark Sawatsky WSCC 1598 and I'll keep #69

    I have #69 reserved with the WSCC but am #99 at Nationals. I'll just run #99 here unless the real owner shows up, then I'll break out the painters tape

    Can we switch to #99? I see that somebody has it but they haven't been to any events this year.

    when is the first autocross event?

    Good plan to call it Autoslalom, I really hate the follow up question when I say I autocross "Is that on dirt?" UGH!!

    Spring Nat's 2018

    We are definitely going, and I plan to do better than the 3rd place I got last year.

    At the last TNT, the car felt better than it has ever felt before (new springs and diff) but after my 2nd run it was overheating. It made no sense because the week before I had it on the dyno and it never overheated. I got it back home and checked the usual things and it should not have overheated. I did a leakdown test and it passed with flying colors, and did a pressure test on the cooling system and that checked out, too. I finally pulled off the front cover and discovered that the chain that runs the water pump had snapped-problem solved. Here is video from the Test N Tune And this week I ported the head

    2017 SCCA Nationals

    We are registered and our hotel is booked. I am shooting for top 3 in EMod and think I have a good shot at it, or the new diff and stiffer springs will be a complete disaster and I'll be lucky to get in the trophies-one way or another

    So the last event was a bit of a disaster for me. On the Friday before I was on the dyno to try to get more boost at low rpm because I had been making zero boost below 4000 rpm. During testing, my 69,000 mile fuel pump (the one that is supposed to pump 2500 psi) failed, which would explain why the engine kept running lean. I put another fuel pump on Saturday and came to the Sunday event. During my first run the car felt good at first but quickly started to break up at high rpm and was way down on power. On my 2nd run, it felt like it was running on 3 cylinders and on my 4th run it felt like it was on 2 cylinders and I had to shift to 1st gear where I should have been able to leave it in 2nd. I got it back to Speedworld and performed a compression test and discovered that 2 of the cylinders have only 30 psi compression. I stuck a borescope down there and the video clip of that is included here:

    Craziest dyno experience happened today. I need to remind or share a little background info first. This EBay engine has been randomly going into a limp home mode, which means no boost. And neither the old engine or this one would make any boost at all below 4000 rpm. The wastegates on these engines are set for a really low opening pressure (6 psi) so for the last event I just added a spring to the arm of the wastegate and it upped the opening pressure to almost 9 psi and it made boost at 3700 rpm. For the dyno session, I added more spring pressure and it now opened at 12 psi and was fully open at 20 psi. They strapped my car down like normal and I warmed it up then shifted up to 4th gear and mashed the throttle. The car started to rev then violently went to redline, like the tires were spinning or something. It turned out that my new for 2017 ceramic clutch was slipping under load in 4th gear. Right there on the dyno, I removed the trans to adjust the hydraulic release bearing and put it back together. This changed nothing, it still slipped like mad (see YouTube video) so Brian Wall suggested I try a pull in 3rd gear. Since this was just a test to see if the clutch would hold, I didn't start the GoPro, but I sure wish I had because it would have made for an unbelievable video. I stomped on the gas in 3rd gear, boost came up, the front tires came right off the ground and the car danced around the dyno-it was crazy!! While they double strapped the car down, I looked at the data logs and the car was making 10 psi by 3000 rpm and peaked at 31 psi. On the next run, when I was actually able to go all the way to redline under load, the car was breaking up from being too lean. Jerry from Bad News Racing was hooked up remotely to my laptop so he looked at the logs and saw that the throttle was actually opening just 50%. I was making a lot of power for just 50% throttle opening. Just to be sure, I disconnected the extra spring on the wastegate and we tested again. It wasn't as lean as before but it also wasn't making the boost and the throttle was still only 50% open. Jerry made more changes and we tested and re-tested but only had moderate success with the throttle opening problem. Then the fuel pump solenoid, which controls the high pressure fuel pump, failed and put the car into limp mode. We found our problem. There was no point testing further because data logs showed that the solenoid was not allowing the fuel pump to get to the pressure it was supposed to. Fortunately, I have a spare solenoid, and I have another clutch so I hope to make it to the next race event. I would link the video but this site won't let me.

    Whatever is causing this problem sharing videos needs to stop. Who can look into this?

    Event #5

    A great course, I enjoyed it. I bounced against rev limiter (70 mph) for a lot of my 1st and 2nd runs. For my 3rd run I shifted to 3rd and was really flying but didn't slow enough for when the course tightened up and spun it good. Similar problem in 4th run, using 3rd gear but not checking up enough when I needed to. There were low 55's for the taking but I couldn't pull it off.

    We loaded the new tune for day 2 and Briget came back from her first run reporting that the car was "F%&King Fast!". I went out on my first run and didn't push hard because the course was really confusing on the course walk and I wanted to make sure I knew where to go. My time was slow and I dropped a number of positions but felt I could make that up on my 2nd run. Sadly, I had no boost again on my run and was really slow, and only Briget was slower. She was having her own issues with not pushing hard enough and braking too early, a result of the car being a lot better this year but our brains haven't quite realized it yet. I re-loaded the new tune for her 3rd run and logged the data. She had boost for her final run but as a precaution, I cleared the DTCs and loaded the tune again. I felt immense pressure because nearly the whole field was ahead of me and I had to pull one out on this last run, and hope I had boost for all of it. I took off from the start and boost was definitely there, I tried to take my mind off what the car was doing and just drive it. I felt like it was clean and I rolled to the scales to get my weight. I had no idea if I had a good enough time to get 3rd place back and didn't know until a competitor came over to congratulate me on my 3rd place. I was surprised and pretty happy about it. These were the top drivers from EMod and I managed a 3rd, despite my problems.
