Never before has so little power been made from so much displacement! (Page 56 of 57)

oh, here's the other thing. if i were to do it again from scratch, i'd just tilt the motor down a bit, use a single v-drive and a transmission geared for a diesel

there is nothing wrong with the idea, but unless you want to make custom gears, you really need to find something with the existing gears needed already. you could possibly do it with a couple FWD ring gears and output shafts. not entirely sure.

T-55?
1500 rpm's were fun. What you gonna do with 15000?

Oh heck yes

Seems like an appropriate time to lock this thread then, and move on to spinnier, louder, hotter things!

besides, whoever gets this subframe and bits will need to continue the madness.

(and, as far as the concentric shafts go, it's just one: the output of the hydrodrive center section. outboard pump driven by the starter ring loses the need for the third shaft, and the non-existence of planets/sun loses the need for the first.)

sorry it took a few days to get around to this guys, but here's the vomit cam video:

*edit* the video encoding screwed up, gotta re-render it.

obviously the camera angle idea needs a bit of work.

That worked great. Any of the CMOS cameras are going to look like that due to the rolling shutters.

I may rig something like that for our car to put on the webcast for the Fall CMP race.

Time for the final summary.

first up us the goldwing box. i figured this thing would look like it was on it's last leg. much to my surprise, it is showing absolutely zero signs of abnormal wear. the oil came out nice and clean and the tooth faces are still perfect.

this is pretty impressive considering the components were spinning what they would be at about 190mph and more torque than a 1st gear launch in the original application. these cheap gearboxes definitely have a future in my toolbox of fun bits to build stuff out of.

the images are huge so i'm just linking them:

2nd i suspect is the reason for many of my engine issues. i took off a head when pulling the engine and this is what i found:

i needed to run this motor way hotter to burn that stuff up.

If i were to continue this (i'm not, the motor is already sold) i'd do the following:
1)replace the 3000GT box with something else
2)spend time on a dyno to get the motor to run much better
3)better shift linkage

That's it. I suspect with those three changes, it would have raced all weekend at about 3mpg. but certainly if i were to do it from scratch i'd avoid the two 90degree boxes entirely.

it did not feel like the plugs were fouling. but it sure looks like it. i suspect the dual LS1 coils per cylinder were able to punch through that grime without issue.

the other box looked like hell. the face of the gears was not so slowly wearing away. the oil looked like high dollar metallic paint.

the red silicone is just because  it's what i stock at home. the gray/black aren't rated high enough in temperature to be used everywhere, the red stuff is. plus i get it from a buddy that is a lawson distributor in a pressurized bottle: http://www.lawsonproducts.com/webapp/wc … FSILICONES

in short "it's easier".

the other box is now in the great junkyard in the sky. i threw it out before leaving joliet.

but picture what bevel gears would look like if you replaced the oil with a polishing compound and then put a ton of torque through it.

It wasn't pretty and even if the welds hadn't failed, the gears would have failed within 50 laps.

you're more than likely correct about the spark detour. but with 5.5:1 compression ratio and no swirl/squish to speak of, it's not like we're hunting for the last 1-2% of performance here.
