I have warched quite a few videos on intake design limiting power, and have been shocked at how big a different a proper/improper intake can make. Two that come to mind are the Gears&Gasoline Kseries and the MCM LS3 E30.

DocWalt · 07-26-2021, 11:16 AM

Yep, proper intake design is HUGE. I bet this doesn't gain anything power wise, like nothing really does on the RX-8. Stock is fantastic... it just blocks all of the airflow out of the radiator

DocWalt · 08-02-2021, 01:39 PM

Intake did nothing for coolant temps at autocross.. As I expected

I coned away 2nd in PAX/STX win and Amy pulled off 5th in STX. Lots of distractions with bad course workers not getting out of the way or grossly misplacing cones so we had some re-runs. It was tough to keep the Nankangs cool in those conditions with a lot of hot laps, but oh well! Amy keeps finding little things to improve and she's finding a ton of pace, I'm looking forward to cheering her on at nats!

My fastest coned run:

Back onto the Yokohamas on both cars, hurray! SUPER close results. 40th in PAX was only 1.2 seconds off of first, wild.

Amy's fastest, good for 4th in STX and 40th in PAX:

My fiancée Amy was codriving with Eric Simmons to get ready for nats too! Simmons pulled off the win in STX with Amy not far behind in third. RX-8 is well sorted now too. We're looking forward to killing it at nats!

Another super competitive class. Good luck in Nebraska. Looks like the team is ready.

DocWalt · 09-27-2021, 11:25 AM

Unfortunately Amy & Simmons had issues with cameras/tablet and only really got data from the Pro Finale. No videos to share, sorry! Amy & Simmons both had issues with the christmas tree lights, car setup, and mistakes. Simmons redlit away 2nd place, just not a great event.

Amy and Simmons had a better nats, but had to make car setup changes often too. So weird that the ProSolo setups that worked well were terrible for nats! Simmons finished just outside of the trophies after really struggling with the car setup while Amy finished up second in STXL! Amy worked hard and had a huge back and forth battle with the winner and it was a ton of fun to watch. Amy was leading on day 1 and every run would take the lead back on day 2, but just missed out at the end. She still got a huge trophy and had a ton of fun!

Amy's second fastest West side run (camera issues again):

No video for Simmons (yet more camera issues...)

Saturday, NNJR SCCA had an autocross at MetLife stadium. I had a lot of fun but never *quite* got a run I was happy with. Still, third in PAX so I can't complain! I think I wrapped up the NNJR Driver of the Year too!

https://www.youtube.com/watch?v=uDY14bhTN7o

Philly SCCA had an event at Ripken Stadium in Aberdeen. I designed and set up the course... and then took top PAX by over half a second. Only tiny mistakes keeping me from having a perfect run, but I'm pretty happy with the result! Need another good one next weekend to clinch the Philly SCCA DOTY honors again!

https://www.youtube.com/watch?v=_JzYGoMeY9w

Matt Meyer codrove and did well, coned away 2nd in PAX with this run!

https://www.youtube.com/watch?v=mKGSBVgW_os

Unfortunately in the meantime, I've got a transmission to replace. It's a little crunchy and 6th gear synchro completely died on the way to nats... and now I have a CEL for the rear O2 sensor heater circuit. UGH.

DocWalt · 10-06-2021, 11:30 AM

Great to be back to Warminster with Philly SCCA! A little different format, but still really fun. I ended up wrapping up Philly SCCA's Driver of the Year honors this weekend. Amy ended up third in STX for the year too, really good weekend for both of us.

My second fastest dirty run (weird data issues after having to stop for a downed cone on my first run that set the finish in the wrong spot in SoloStorm):

https://www.youtube.com/watch?v=F3xGQiUZ-wM

My fastest clean run:

https://www.youtube.com/watch?v=slCd0c-NbJA

Amy's fastest dirty run (I don't have a clue which run was her fast clean run due to both of us getting reruns due to poor course working):

Got the water pump underdrive pulley installed easily, just bolted on like stock. I've done some logging too, good temps while cruising around (180F stable with AC on, as usual) and temps so far are better at autocross. They still recover super quickly too and I'm not seeing as wild high temps. I used to see 217F at the end of autocross runs, I've done one event and I'm only seeing 205F as a peak on course even with a lot more rev limiter action at 9800 RPM. No more autocross events planned this year for me, sadly. Might get to do a track day or autocross, unsure though!

Big thanks to Dennis at HGB Motorsports for the pulley and hand delivery at nats!

DocWalt · 10-25-2021, 12:15 PM

I made a spring rate change from 672/448 lbs/in to 800/600 lbs/in (front/rear) after the last Philly event. It was a huge improvement in ease of driving the car, so much easier to place the car now and it even rides better on the street. I need a little bit more front bar, it was pretty loose (especially on exit!) and my front bar is maxed with the rear disconnected. I'm upgrading from Hotchkis RX-8 front bar to Progress Tech, the bar rate change should mean I'll be towards the bottom of adjustment on the Progress Tech so I may add a little bit of rake to balance it

Yoks were really BALD but we did well. Fastest STX car and just about fastest <400hp car at NNJR. John V's car dominated PAX with Evan Schickel at the wheel. Clearly his changes have worked well too, haha.

My fastest run:

https://www.youtube.com/watch?v=dJZ2Trp6vSo

Talha's fastest run:

https://www.youtube.com/watch?v=DsW1rTbM008

Interesting side by side comparison of us. I made a bit of time on the first two sweepers then Talha made it back in the big slalom. I was a little bit out of position for the sweeper after the big slalom putting me out of position for the final turnaround but it wasn't worth more than a couple of tenths.

DocWalt · 11-10-2021, 05:59 PM

Upgraded to a stiffer front swaybar, Progress Tech's RX-8 swaybar.

Cleaned the air filter and added a filter sock to keep water out of it when it rains. If the car was parked and sat in a longer rain storm, enough water would drip on the air filter past the hood seal that it would mess with MAF readings and run poorly until it dried out enough. Annoying!
