Thanks! The shifting issue (though it's 4th this time instead of third) is back after switching to a s1 trans again. I think this proves that I cannot use a s1 trans behind the k without issues.

@@D1sturb4nc3 Yeah, there's another 0.5s in there with cooperative transmission!

@@D1sturb4nc3 Time for a S2000 trans buddy, much better suited gear ratio for K engine.

@@koawang0609 I've been considering it. I drove a s2k not too long ago and the gear ratios are so much better.

Thank you. I left a little time out there, I think. Suspension is the keisler automation Penske setup, 7500DAs. I've got the P2M rear arms, stock front arms with the mazda camber offset stuff.

@D1sturb4nc3 excellent choice with the extra travel rx8 needs

@@ogrigoros131 Yup. I had some BCs on the car previously and it was a handful (see ua-cam.com/video/qHuT3YadOtA/v-deo.html for example)

@D1sturb4nc3 very big difference, with the Keisler coilover is more friendly and seems to be much faster

I think 8200 was too much for a stock bottom end k24. Data looked good, no bearings looked bad so that's the only guess.

seemed to matter less in practice when I did t1 better, which was what I based the shifts off.

@@maximedalens6314 nope, car was loose under power on exit then boom

@@JackieDing86 highlight of the weekend battling with you. Too bad the yellow flag owned me!

Thanks man! I feel like there's even a bit more left in 2. Definitely a 46 in the car.

Car was down some HP over last year at this event for a variety of reasons (false knock, different bottom end). That's been found. Oh and I had essentially no clutch for this TT, RIP third gear synchros.

Thanks! There's a fair bit of time left in the car still I think with some better driving. Car is on the Keisler Penske setup & his front sway bar. Rear bar is the racing beat one I believe. For this lap it was stock arms all around with the Mazda camber offset metal bushings in the front knuckles & delrin UCA bushing. I ended up going to the p2m rear arms this year as they're legal in the class I'm running now.

Thanks man - yeah I was up a half second until I blew 4. Still the best lap, but it was a low 20 not a high 20. Great point on 4. I think you're right that i'm sending it in a little deep there. I've been trying to focus on the exit and I struggle to get the car to rotate on entry there i feel.

Motor seemed to lose oil pressure / overheat and seized. We swapped it that night.

@@D1sturb4nc3 ah crap. You know what caused that?

Driver order was: Bob, vince, Mike, Brandon

Both rx8 gearboxes have a pretty big drop 2 to 3. I'm probably going to try 4.7 gears next year, which will help some. The car has 4.44s now

Won't help the massive loss of revs 2-3, will be the same! I don't get it, how hard can it be for sports car manufacturers to give us decent ratios where 2-5 are super-close, and 1 is granny-gear for getaways and 6 is super-tall for highway mpg. Seems like nobody does this right!

Yeah, the 2-3 and 3-4 spacing sucks. 4-5 and 5-6 spacing in this car is way better. Nothing to be done about it, though I think the taller rear end might be a positive.

Yup, shifts are much much better now!

This is awesome, thanks for the video & doing the comparison. I dyno'd at 220WHP using NASA dyno rules (COM requires the same rules). Turn one is all the driver, the car has significantly more in it there, but I backed it into the tires there a year ago and just never worked up to full pace this event in T1. It cost me a ton of time. I think I'm leaving some corner speed out there in a few other spots too. Specifically, I think I can hustle harder in the bust stop, 6, 8, 9 & 11. Shifting also is killing time, I'm swapping a s2 transmission in before my next event hopefully, if I can make it all work with the p2m kit. Thanks for doing the math there, I knew it was time but that's shocking. Does NASA TT5 allow aero? That might be why my corner speeds are similar on re71rs rather than A7s? Weight wise, I could drop 200lbs without doing anything (ballast, pass seat & not running a full tank), I suspect I could get close to 2800lbs race weight, but I haven't removed much weight due to trying to stay in a COM class. My cage is pretty beefy, so that's a little extra weight over a minimum requirement cage.

@@D1sturb4nc3Can confirm he's got rear wing, no spliter but not sure about airdam

@@D1sturb4nc3 You're welcome man, best luck next event!

If you were using the collins kit, it was constantly walking out the pilot bearing & not letting the trans spin down at high RPM for me. This even killed a transmission input shaft bearing eventually. The PMC one is better. I think I just need to figure out how to get my s2 rx8 trans to work with the PMC kit and it'll be excellent.

Yup, but I missed some more shifts (nothing as dramatic or as potentially expensive as this one) each session after. Didn't go into 4th once during the TT which ruined a lap.

@@D1sturb4nc3 Ah yuck... that's something that'll kill your confidence for sure. After I miss-shifted with you in the car I put in a self centering shifter (don't have to worry about doing detents on future transmissions). Would totally recommend one.

Yup, I fucked up. Trans felt like trash all day Tuesday, but was fine Monday. Maybe it was just the driver.

We were the black honda accord with a chevy grill. Hondarado.

Damn, I didn't think of the dirty air excuse! The flag guy sure could wave it, if it was anyone else I'd have missed the checkered.

I've done very little weight reduction and have a little bit of ballast for classing reasons. The cage is pretty beefy though.

Yeah the infield and the black pavement in a few spots was very slippery. This was on rt660s I think. I switched to re71rs and they were slightly better.

Thanks man! I wish I got some more dry time out there, I think I left some on the table in a few spots.

It's a lot more fun to drive. The saab was fairly well dialed in, but was doing some things that required throwing a lot more parts at the car to fix. Namely it was lifting a rear tire almost everywhere and the WRX transmission couldn't handle that. Setting that rear tire down meant ruining the turn in and front end grip so it was a game of trade offs. The rx8 chassis is just fantastic now that it's getting more dialed in. There's quite a bit more grip and the car is just plain more fun to drive. The saab was a little quicker in a straight line, but I think the rx8 should be the faster car overall this year.
