Truck blowing it's transmission has pretty much killed racing budget for the year. Any monies needed to properly prepare the car for a 24hr race are pretty much gone at this point. It also killed most of my motivation...

The truck pictured earlier in this thread...1998.5 Dodge Ram 2500 Cummins. Trans is a 47RE with ~20k miles on a documented rebuild.

One of the main reasons I bought this particular truck was because it had paperwork for a recent transmission...

Oh well...you gotta pay to play.

Slow pit stop...






We had some mechanical issues and the car wouldn't take fuel worth a d@mn, ended up finishing ~40th out of 105ish cars.

Cool! Looks like you were out there with the GRM Miata project car. Love the Gulf livery 944. That color scheme never gets old.

You know, I've been following the GRM Miata project car in the magazine, and I never thought to look for them at this race. It makes total sense they would attend that race considering they are based in Daytona. Honestly, there were 105ish cars registered...I forgot to look for them specifically.

And yes, Gulf liveried car looks awesome, that's why I included that picture.



As for the car, it's been bashed up quite a bit the last two races, and used up quite a bit too. The car needs some fixing up and some wear and tear items replaced. It's kind of sad because the car was SO clean when I bought it, but ~40 hours of enduro racing later and it's showing it's battle scars.

The motor I built has lasted the 28 hours I wanted it too, but the valve stem seals I never replaced seem to be leaking more and more. The car still runs fine and seems to make decent power (by decent I mean about 50hp less than most competitive ChumpCars), but I think it's time for a change.


ENGINE SWAP COMING...

Some ChumpCar video from this last weekend.

Not my car, I was guest driving. It's a K24 powered EK Civic with a 6 speed Civic Si transmission. Motor is bone stock internally; just intake, header, exhaust and tune. This car races in the "EC" class i.e. the Exception Class i.e. the cheater class.

Transmission ate 4th gear after about 70 minutes.



Seefo's car makes an appearance at 6:15 and hangs around for a while. We had some pretty good "racing", even though his car completely meets the rules and the one I was driving doesn't so much...

Doh! Let me look into it.

I don't think the sound worked for the entire video anyway. I may have to re-upload it altogether.

Why do I suck at linking YouTube vids?

Also, not my car, not my mirror. I was fixing it...three times a lap

seating position looked a bit uncomfortable, or is that just the angle of the camera?

also what happened with that pass on me in T7 (~20 minute mark) I remember being confused there. Or was that courtesy slow down on the miata to help me out

Seating position is very uncomfortable. I can't remember what brand/type of seat is on the car but it's garbage. The side "bolsters" on the seat don't fit me at all and they force my elbows up quite a bit. The steering wheel isn't good either.

If you watch any other videos of my driving, I never take my hands of 9 and 3 (except to shift, wave to corner workers, make rude gestures to other drivers, adjust a mirror, get a drink, play with a lap timer,etc., etc.) and I don't do any steering wheel "shuffle". In this video I'm doing all those sorts of things and it all has to do with the driving position in this car.

I've communicated my displeasure with the driving ergonomics to the owners, but I think durability and reliability is current their top priority.

As for the pass going into T7, there was a yellow flag. A standing yellow at the corner station for the stalled BMW off the track. It was there the lap earlier and I forgot about it until I was side by side with you. I didn't want to get blacked flagged so I slowed way down to let you past ASAP. Apparently it worked as I was never black flagged...

Hmm, I had a hard time with that one. Technically when are we past that incident? on Sunday the Integra passed me after a yellow right out of hogpen. I was playing it safe, but he didn't (and was not black flagged, not that chumpcar really blackflags that much for passing under yellow).

This one was hard to tell because technically once you turn in, you are past the incident...Any wisdom there?

This one was difficult to determine when you were technically past the incident. I'd say your interpretation of any point after turning in basically being past it. The safer assumption would be at any point past the apex of the corner maybe?

My understanding of ChumpCar rules, at least those enforced by the Eastern ChumpCar region, is that you are under yellow flag rules if you can see the flag station with the yellow shown. Basically line-of-sight, within reason. Since there's basically a straight for quite a ways before this corner station, there's a fair distance of line-of-sight. I would say well before the bridge.

Since I initiated the pass and mostly completed it all within sight of the corner station I felt, by Chumpcar Rules, I was pretty clearly passing under yellow.


SCCA rules (and IMSA and maybe NASA?) are that the yellow flag is enforced from the corner station showing/waving the yellow until you are past the incident. In this situation the yellow "area" would be really short, if not almost non-existant. Under SCCA rules, if you complete the pass before you reach the corner station showing the yellow flag, then you have not passed under yellow and you have the right to track position. In this case, if this was an SCCA race, I would probably have done the exact same thing and erred on the side of caution even though it could be argued that I completed the pass before reaching the corner station.


I've been passed under yellow countless times, and have seen the offending cars black flagged maybe a dozen times. In my experience, all of the organizations I've raced with (SCCA, NASA, ChumpCar, WRL, IMSA) have been about the same as far as enforcing PUY's. I'd guess about 10% of the time the penalty gets appropriately enforced. In IMSA we would immediately radio in any PUY's, and even with video replay available, IMSA missed them more often than not.

Still racing this.

Motor I built before Daytona last year is still chugging along. Approaching 40 race hours on that motor.


Raced at Road Atlanta a week ago today.


Looked like this:











Rotor shouldn't be that hot...not on street tires. Front left brake pads failed twice in a 14 hour race. I assume something was causing the left front caliper to drag leading to overheating. Still a little stumped by it all.


Big changes coming for this car...may involve a certain K20A2 that is sitting in my garage.
