Motorman let me address this issue, you claim to work on motors or is it engines? there is a differance. Motor = Electric, Engine = Nitro or Gas. What makes you think that you are boiling alcohol in your fuel tank. Do you realize that the plastic on your fuel tank would melt at that temp. How is the temperature of the fuel reaching p.

So why has a motor bike or motor vehicle not got an electric motor powering it wise ASS?

Motorman, you going to take that crap from someone who, I bet, don't even race? Everyone has an opinion.

By the way, what was the answer to my question abuot how to adjust the two speed with the pipe running down the center of the car. Also, what do you think about mounting the tank on little springs and not orings???

get your facts straight.

1.) Motor is a latin word for setting something in motion. In most other languages motor is used for both, electric and combustion.
Do you know what DMV means? Probably not at your age.

2.) The plastic our tanks are made of is either polypropylen or polyethylene which both have dimensional stability (ASTM D1204 ) of > 1% @ 180F/1hr (82.222 C / 1 hr) This means that PP/PE changes dimensions less than 1% at that temperatur over an hour.


Methanol, which makes up approx. 55% of our fuel does boil at 64.7 C (148.46F or 337.85 Kelvin for a rocket scientist like you)

What else did you want to know?

Default Stop the Turtle!!!

Motorman, I got my car as good as I could ever want in the S-bumps and all by Sunday. I stepped up to 42 shore fronts from 40 and lowered ride height by a half a mm all around. I also widened the track -again!!! All very small adjustments. Basically everything I was doing was to get more initial steering without doing the turtle. What I think was happening was I had a push so I had full lock on the steering wheel over the bumps. When I got car to turn better, I wasnt turning the wheel as much and therefore car was more stable in the S. But thats just my opinion.

I also went with fairly soft springs red/red and I think that helped a lot as well. I could go flat through the S on different lines and car was planted and it would dive tight to the hairpin at the end!!! The other changes kept car from traction rolling so I could use all that traction and grip. I was very BUMMED that we did not get another qualifier. I wanted to prove to myself that I could put it in the middle of the A. Oh well!!!!

Default Dennis, help please!

I got a Collari XS 12 that I ran for the last 2 weeks w/o any problems. It has gobs of power and runs pretty cool.
Yesterday, every time I started it up, it ate a glow plug (MC 8, ambient temp ~95 F, O'Donnell 30%)
The coils of the plugs were all distorted but still in place, so none had fallen into the engine.

It looked to me like too high compression.
I took the head off and found 2 copper shims, piston and sleeve looked good.
I replaced one of the copper shims with a Nova Rossi aluminum shim, to get the same clearance (0.4mm) as with my Mugens.
It still destroyed the next plug.

I took it out and put my RB in the car, which ran fine with the same plugs.

Any idea what could be wrong?
I didn't change the settings and the weather was the same for the last 3 weeks.

Thanks,

Stefan

Hey Stefan , ive been running Collari 3 port "dowunder" very successfully for 5 months, our climate is similar just different wildlife. Try this, with 30%, shim the engine to .5 and run novarossi 6 plug, i have tested plugs and have found this to work well. Ritchen 1/4,run engine and re- tune on track. If you run 16%, then go back to .3 and stick with the nova 6 plug .Try to use collari shims or picco "same", good luck.

thanks for your help.
I actually opened the motor yesterday and found some very small metal particals in the bore of the crank.
No clue where they came from, crank, piston and sleeve are all fine.

Oh well, I cleaned it and will try it now.


EROCK, Huh??????
