Nice!

I do know that feeling, rising temps normally cost me a second, or even two. I don't always use my fastest lap as a reference for next time.

1:25.2 at Streets of Willow Springs

Holy sh*t. Mod list? I'm gonna update the original post.

Thank you! All results since 2017 added to the main post. Sorry about that, hard to believe it's been almost 2 years since the last update. I haven't run at all this year, so live vicariously through your posts.

Use to run street willow a lot when I still live in state, Miss it !!

ZOMG, your rear spring rate is too high compared to the front rate!!!!

:rolleyes: :rolleyes: :rolleyes: :lol: :lol: :lol:

Wow, great driving, car prep and video overlay! What software are you using for that?

Looks like I never shared my SoW CCW time from last year. That was my first (and so far only) time there and had a blast.

Streets of Willow CCW - 1:27.64 -- blu3dragon -- RX-8 S1, estimated at 185rwhp and 3000lbs w/driver. S2 transmission & Diff. Race seat, harness & roll bar. APR wing & DIY splitter, Fatcat coilovers, Toyo RA1 255/40/17 tires (previously used as wets).


Now that I've seen RE-Vision's lap,I need more practice, more camber, and maybe CW is faster? :-D

yes my setup doesn't work at all i've been told by many people :smoker:

CCW is supposed to be faster. We'll see, I'm going to do that config next month.

well I’d make a few different choices and cut another 80 lbs off, but overall am fairly impressed with your car. Definitely put you up in the upper elite category as far as STX RX8s that I’ve seen over the years. That’s about a handful or so.

NCM Motorsports Park 2:20.2
Putnam Park 1:16.4

315 Yokohama A052 on all four, a bit over 2600lbs

Car is built for SCCA Time Trial series.

~2700lb
stock motor, lot of custom bits otherwise.
Pulls a lot of G in high speed corners
315 square Yokohama A052

NCM 2:20.2
SCCA Max3 class track record, won at nationals 2019

The car in the same configuration also ran at
Putnam Park 1:16.4

Next year will likely drop a few more lbs and run Hoosiers for unlimited 2.

Oh, nice!

Hit Buttonwillow CW13 this weekend. First time at this track in 4 or 5 years and the last time was just one lap in my Elantra, safe to say it's basically new to me. Got a 2:02.3, lots of little and one very big mistake to fix next time, pretty sure 2 flat or faster is achievable.

2:04.09 at Chuckwalla CW on Saturday. Will upload video when I can.

was in town for 10 days. took RX-8 i bought 2 years ago to drive at street of willow
I think i did ok 1:29.8 desptite using 6 years old Champrio GT that come with car

nice!

Thanks , ur lap time is very fast
How wide of A052 u are using

255/40/17

Here is a 1:38.1 at Gingerman
Stock engine. 315 A7s. Lot of downforce and weight reduction.

that’s smokin’ compared to the other times posted for there :bubbrubb:

gotta watch those rev limiter hits though :suspect: edit: maybe you’re on the gas still when the clutch pedal is going in instead?

have you measured tires temps with a pyrometer? i feel like 315 width hoosiers would take a while to get to temp.

that’s a good thing with the A7 compound, downforce and those cornering speeds are going to warm them right up imo

nice run. is the car tuned or stock ecu.

seems like maybe you’re playing it fairly safe on the curbs?

Tuned, although I've not got further than adjusting the AFR and even that still needs work (I am aiming for 12.5).

I missed the apex of t5 just slightly and I was slightly conscious of not wanting to put any wheels off, but otherwise I think this is a pretty clean lap. Of course there are always areas to improve... Maybe on entry curbs? There's a compromise there as they are so aggressive it can upset the car a little on braking and turn in.

yeah sorry, my reference was for entrance and mid-corner

having never driven there I can’t say, but watching the vid it seemed like there might have been some time charging over them more.

you should shoot for 13:1 AFR on a Renesis.
.

Bolded for truth. Lots more power targeting that, even on the old butt dyno. Remember timing needs to be tweaked too, generally less timing than stock with a tighter split.

Anyway, to get back on topic.

VIR laps. A 2:11.2 followed up by what was on pace for a 2:10.9 or so.

Hi there,

I noticed this post when researching info on engine compression relative to actual power. In your experience how does low engine compression affect your lap times? Do you see lower top speed on the straights? Can you estimate how much of a performance hit there is on track given a specific compression loss. Like say is a 10 psi average loss worth 5 mph on the long straight of your favorite track?

Also what point of lost compression or track performance do you consider an engine refresh?

Thanks,

i don't have a definitive answer... no apples to apples. but i guess at a ~2 minute circuit it was probably 2-3 seconds, although my low compression daily driver feels quite strong even in comparison to my white car so it could be even less.

my new personal best at VIR, 2:07.83. close to previous track record set by s2000 in TT5 class.
car is 2900 lbs comp weight and 195 average whp.

Hot. Flat-out through climbing esses too. As it should be. :ylsuper:

flat out through T9 could get sketchy when trying to come back over to the right for T10 while left foot tap the brakes for pad knockback then get on the brakes quick for T10.

Audio is wind noise because GoPro is not good. Ran a 1:33.6 last night at NJMP Thunderbolt during TNiA. Running Nankang CR-1s instead of Yoko A052s, but no setup changes from autocross.

So I just did my first timing at gratten or ever for that matter. Cold wet day to start track was bit slick and definitely not my fastest time.
131.36
racing beat shocks
ebc rotors with cobalt friction pads front rear
falcon 245/40 rt660 with last bit of life on them.
2010 stock sport
pretty sure I can get under 130 if it want wet rained till 1pm.
I may try and get back in a few weeks. Track will be cold but better than last week.

Here are a few PB as of current

Mid Ohio is always a good time, and had a great weekend in HPDE with Gridlife.

Video should start just before the start of the fast lap:

That's a solid lap, very similar to what i turned in my old white car. nice job.

Thanks! Lots to improve still, but was fairly happy with the progress throughout the day.
