I know I had issues with a new timken bearing replacement on my RX8 earlier this year, Was odd being as I've never had any issues with them before.

Good luck!

Switched to national which is federal mogul which is a rebranded NTN which is OEM. however when leaving today my cheap main circuit breaker took a dump on me today, I don't think it likes being in the sun all day when its 90 degrees outside with no shade...

popped it after a few cranks of the starter and now it mechanically re-sets but doesn't electrically give my continuity... FML

Why do you have a circuit breaker between the battery and the starter. Nobody does this, and for good reason.

safety? But now in hindsight it seems with the master cut off switch its like belts and suspenders...

Damn, no idea how I have not been following this thread, having actually raced against this car when we were both rallycrossers....Hope to see you out there sometime soon on the stages - you should come to Black River...me and Nonack and some other GRM'ers will be running there :)

its for sure on the list! However this September is a bit busy for non car events and summer sno*drift is this weekend and if all goes well I will be at LPSR. Still need to fix the tow vehicle too which is another project now... until then I am mooching my co-driver's new f150

lol nice. well, look at the BRS entry list right now and you may change your mind. OVer half the field is RWD (including two RX7s)

two e30s, an M3, two RX7s, an XR4Ti (Nonack), a Mighty Max, a Ford Ranger, a Mk1 Escort, a Starion, two Porsche 944s, a Volvo 240, and a Lexus IS350......

trust me I wish... GF's birthday event among other things and we decided to visit NYC. Personally my first visit to NY would be upstate but pick your battles, am I right? haha

real wheel drive! We have good turnout this event for RWD too: Datsun, 1st gen rx7 (G5), my rx7, old school celica, mike hurt's cosworth powered capri, E36 3 series and I think an E30 as well

Is that the RA64 Celica with the Marlboro colors on it? If they so much as hint that they might sell that thing you have to let me know

Yeah that's the one that's the Andersons', they're good friends of mine. I'll be sure to drop the hint but I don't think they are selling it any time soon.

No, you don't need to harass them about it- but do tell me if they say they're thinking of trading it for, say, a turbo Ford product...

You can tell them I said thanks for helping us get our RX7 out of the stage at Magnum Opus, though!

Summer sno*drift is over and it was a complete & utter failure. Some minor tweaks to get through tech (no big deal) and then we were ready but the 1st stage was boulder city - just stones and loose sand everywhere the car shut down about 5 corners in, something with the fuel pump relay - jumped it and kept on going.

about a mile later the exhaust fell off at the v-band due to rocks or something, the car is too low when a full tank of gas and added spare + tools etc with too low of a vehicle to begin with. I will have to upload some video of it - if it was recording... because an open header rotary is loudest thing on the planet, it physical hurt it was so loud but POR! I literally could not hear the co-driver over the volume of it.

Shortly after that the engine died again and sweep had passed us so we we handed in our time card and we were done for the today. Verified spark/air/fuel and determined it must have been an ECU issue. Luckily the exhaust was dragging behind us hanging on 1 rear hanger. Tossed the exhaust section in the back of heavy sweep and the towed us about a mile to a recoverable area as the the stage was about to be re run shortly.

Found the issue by wiggling the connector and the car fired right up, better than push it up the trailer:

so we bust ass in service and get a new v-band on the exhaust, weld the 3 pieces together so they don't pop off and help seal some of the exhaust leak as well and fix the connector so that its properly installed. good to go after service and get to start last but we get to start. 1st stage out we get held up by an accident (spun blocking the road) then we basically transited behind 3 other cars to the end.

After that head to stage 6 and it was a blast! saw coolant temps as high as 220F but I didn't care it was running great and we were having fun. Tulips were virtually useless I don't think my co-driver said anything productive on stage all day. Then we got lost heading to stage 7 because we turned on hardwood hills not hardwood road and then got stuck in the sand, giving us a DNF for the day.

We had issued with tulips on prior transits and caused me to doubt my co-driver. I thought this was the wrong road and we saw some familiar tracks so others made the same mistake but didn't go as far as us, so I went in reverse and kept going the whole way back (1/4 mile or less) then decided to listen to my co-driver once more and went to turn around at a spot but when I lost momentum we were done and just sank.

We missed stage 7 & 8 and didn't even go to parc ferme and did not participate in awards, beaten and ashamed we headed back to camp

but well that's racing... next steps for LSPR? probably not competing - I need to raise this car in the air to gain ground clearance and the proper tow truck needs the engine replaced/rebuilt. it was awful being crammed into an extended cab f150. Probably just going to spectate this year.

Here is the video of stage 1 after I got the car running again, the exhaust falls off - it gets SUPER loud and then the car dies down the road later for unrelated exhaust reasons.

Sorry to hear about your challenges.

Re: LSPR - don't spectate - volunteer. Rallies always need more workers and its a way to give back to the sport.

If I get the truck ready in time I would love to be apart of heavy sweep. I haven't spectated a rally in years either so it would be nice to do that again.

APB to the MS guru's out here,  I am having trouble re-producing this but I have logged the issue. Its like it fuel starves kind of misfire. It  ran fine when parked but then after sitting for a few months this issue started to occur. Any help would be appreciated. The last 2 rallycrosses (most recently this past weekend) have been interesting with an intermittent miss...

 

Here is some background:

  • I have tried a new fuel filter and new spark plugs are on the way but cleaning the existing ones yielded no benefit to the situation.
  • At first I tried adding a ground to the CAS and it seemed to help so then i tried cleaning the CAS body to ensure a better electrical ground but this had no affect either but i wasn't getting a sync loss error so it didnt seem to loose RPM signal.
  • ECU connector is on tight, gave it the wiggle and screwdriver test.
  • fuel pressure does not drop when misfire occurs
  • typically re-created when trying to launch by raising the RPM or mid RPM range
  • Lap times were roughly 45 seconds, when the misfire occurs you can see a lot of off/on of the TPS but RPM is low considering, most noticeable at start line or midway point.

I wish I could help, but I have no idea. Is the tps going crazy because of your foot? Or is it or it's wiring at fault?

No thats my foot... when it misfires I go zero to wot and everywhere in between just to try to get it to unhiccup.

 

 

I gotta try to re create the miss then log just that because right now that s a lot of data from 1 rallycross run lol

looks like I found some poor connections near my fuel pump relay and a relay not consistently switching so it should be all better now! really on the fence about sno*drift
