hopefully it passes tech, but it's 4 bolts to remove if it does not. also i'll add a tether to it in case the glue fails.

We did a mount like that for a car during the One Lap a few years back. The footage was awesome. Up till the mount broke.

Have you seen how good YouTube's image stabilization is these days? It's pretty amazing what it can do as long as it has some object to reference in the shot that is fairly static.

Does it automagically do that?  Or do you have to check a box or run your video through some trick?

nope. i've not uploaded squat to youtube in a couple years, and certainly nothing that was moving in the frame.

i figured stabilization would be built into the camera (within limits, of course), i never figured a hosting site like youtube would add another layer of processing.  good to know.

After you upload a video to YouTube these days it give you a few editing options. One of them is Image Stabilization (and another is exposure correction). What is does is zoom in the video a certain percentage (10%? or less, depending on how shaky it is) and blow it up. Then it finds something in the frame that is fairly constant and locks into it, moving the image to cut off a little at the edges.

Well, it turns out the rest of my video is of more dubious quality than I'd originally thought; first time (and possibly last time) I've used that camera.

Anyway, here are two that are salvageable:

It made it through 8 laps then snapped a shaft in the drive train. I really hope they get it fixed and back out there.

Re: Never before has so little power been made from so much displacement!

Way to go Marc!!  This thing is awesome, it was cool to go by it last year at Gingerman and even better this weekend in Chicago.  It sounds amazing going by when you're a spectator, but driving next to it on the track is truely one of the coolest things i have ever heard.   Congrats on this awesome machine!!!

Re: Never before has so little power been made from so much displacement!

Just got home. The weekend was quite a bit of fun! While it's fresh in my mind, i'll go ahead and post an update.

on saturday i was off to a stunning start, did about 4 laps before she started stuttering. it felt like a severe timing issue. i could not replicate it in the pits, went back out for 2 laps and came in on the strap with the same issue. still could not replicate it in the pits, but decided to take 10degrees of timing out across the board and remove a bit of fuel (10% or so) in case it was a rich miss since i was fairly certain it was rich.

also, i tried messing with the linkage, for some reason i could not get in 4th to save my life. this was a pretty significant problem since 3rd was too short and 5th was too long.

went back out for 2 laps, and the motor started sputtering really badly and one of the hard pulses broke the 3000GT shaft.

i called Adam (adamjabaay on here) up on his offer he made last last week. he dropped what he was doing right away and we drove about 45minutes away to his shop and i was able to use his TIG welder to repair the shaft.

while i was doing this, i sent two other team-mates to search for a replacement seal that was damaged in the incident. i unfortunately thought the number written on the seal would have been enough to cross it but it wasn't. so when i got back to the track about 2.5 hours later with the repaired shaft, there was no seal waiting for me. so i looked it up in the timken aftermarket catalog and found the part number 222830. we then proceeded to go to every parts store in a 20mile radius. the best we could do was order one for 8:00am sunday morning. so we do that, otherwise we would have been back on the track by about 3:30 or 4:00 on saturday.

sunday morning, the seal has arrived, I install it in the car and the car makes it out within a few minutes of the green flag dropping. at first the car is running strong and thankfully there's a full course yellow. still with no 4th gear i spend the next 4 laps balls out "racing" without exceeding the RPM limit in 3rd. this results in the entire field bunched behind me on a full course yellow. top of 3rd gear was about 65-70mph. I'm not entirely sure what caused that full course yellow. there was a truck out doing a rescue but it wasn't in an odd spot and only one truck. either way, 4 calm laps was appreciated.

track then goes green again and the problem comes right back. at this point, i have an epiphany and remember that my coolant temp is actually connected to my oil temperature. it seems that the car was finally going out of cold enrichment mode and probably doing lean misfires. it's not obvious on a 5.5:1 compression ratio. i go ahead and correct that and correct the timing adjustment caused by the same issue.

i go back out for a few laps and then it happens again. apparently i had messed up the fuel curves a bit while hunting for it so i correct them back and it runs great and i go back out again. a few more laps and then it starts missing bad, but now the tach is dropping in and out. that instantly points to a loss of sync issue. so i adjust the hall sensors in a bit and go back out.

at this point, i'm 18 laps in i believe and it's running great. so i decide to go back out thinking everything will be fantastic. sure enough, at that point the shaft breaks again. so i had now made it to 20 laps and no way to move under it's own power again.

i then packed the trailer and wait for the awards ceremony and i end up getting "most heroic fix" which i'm not entirely sure i deserved, but i was happy to accept it. especially since my goal is to win all of the trophies possible.

i now have gotten two with this car:
-i got screwed
-heroic fix

if someone else wants to pick up the flame, i can probably sell the car whole but I think I've done what i can with this motor and it's time for me to move on. i really do want to do a turboshaft in the same chassis but i have to clear it by Jay and such first.

Re: Never before has so little power been made from so much displacement!

Marc, it was quite awesome to see and hear the car run. From my penalty box duties this weekend, I felt like I was in the catbird seat every time you guys fired up the engine (or tried). And then to have the shaft fail and you get it back together again was just splendid. I can't wait to see the videos posted. Cheers!

You know, last time i felt had that they gave it to a pickup truck instead of me even though i only did one lap. but that square back vee dub did deserve it way more than i did. they turned a TON of laps with that thing and it seemed somewhat reliable.

The videos from the rear camera will be posted soon. but i will warn you. it's a bit of a nausea view. the image stabilization is causing a wave through the image.

there's no way i could have gotten it back together without Adam. i greatly appreciate the tools he lent me. That guy has a CRX sickness.

I vote for a Fiat 850 Spider as the chassis for the turboshaft. Mr2 is too big and too easy for you now!

Surely there must be a team that'd want a pre-cut MR2 with a cage for that magical 455/TH425 combo swap?

Re: Never before has so little power been made from so much displacement!

On my way home it finally hit me what your error was.  You really need to study your history.  Mitibuishi in WWII was best known for their Zeros and they were often used for the Kamikazi attacks.  Your engine finally was working (have to say I loved the little puffs of white smoke that came out of each tailpipe as its cylinder fired on your way out on that last trip) perfectly and the 3000gt box reverted to its ww2 setting and took you out of the race.

yeah, this occurred to me a few times during this project. installing an american WWII motor in a japanese chassis seems like something *HAS* to go wrong.

as for that smoke, I'm not sure what that was. i suspect the oil finally got up to temp and i started to burn some of it. i only went through about 3 quarts of oil over the weekend.

the engine head temps were never an issue either. all within 10degrees and around 360F was the max. well within the 600F allowed. i could have probably cut a TON of fuel out of it and gotten more power and more heat.

Re: Never before has so little power been made from so much displacement!

for people looking at taking this task on, a couple questions (and they might well have been answered in this thread already, and i just missed them)....

1) the current order of parts? it looks like Motor -> BMW Guibo -> 3000GT diff -> Goldwing 90* box -> Subaru transaxle (clutch to the front). is this correct? are there any other stockish adapting bits in the drive line?

2) the failure points thus far have been what? the welded adapting bits? all typically due to somewhat erratic and very powerful pulses the motor delivers at lower RPMs?

3) what ultimately kept you out of a torque converter on the flywheel? the need for an external pump and sealing surfaces?


again, not trying to look past your accomplishments on this idea. i was hoping it would run the whole weekend without a hitch. someone wanting to accept your passing of the torch would be best served not making the same old mistakes. they need to get the chance to make all new mistakes.


thanks again for this epic journey....hope it's not over.

thanks again for this epic journey....hope it's not over.

first thing to mention is there already two people in line but on such an epic project they may come to their senses before too long.

1)you have the order right. there's just a bunch of custom adapters and shafts gluing those pieces together.

2)the failure points so far:
a)the CAM sensor needs relocated. i suggest the machine gun cam block off plate and read the actual lobe on the cam. the rocker vibrates too much.
b)the guibo did not fail, but it was on it's way out. it probably would have disintegrated after about 100miles or so. there are aftermarket couplers to correct this, i'd strongly suggest it.
c)the 3000GT box was filling up with metal snarf. the first day was much worse than the 2nd. maybe the gears have taken a new set and just needed to machine themselves to eachother, but likely they would eventually wear through the hardening and then the whole gear would eat itself.
d)i haven't checked the goldwing box yet, but i suspect it's also filling up with metalic snarf.
e)the shift linkage completely blows. I'd suggest a proper linkage instead of this damn push-pull cable affair i have.
f)if you care about your teeth, rubber mount the motor.

that said, overheating any of the boxes did not become an issue. the motor also ran quite cool back there

3)pride. i hate automatics and it just seemed like taking the easy way out. yeah, that's right, i let that get in the way. if you used an automatic torque converter on the motor even if it was still linked to a manual trans with a clutch you probably would have saved everything else.
