Default another design by me

     

Got brakes???

340 CC 2 stroke engine- 2.5" stroke x 3.25" bore (63.5 mm stroke x 82.55 mm bore)

manual clutch

6 speed Dual OD transmission

3:1 chain ratio (14/42)

22" tires

Here's the shocker: speed:

Speeds at 6000 RPM

1st: 3.38.....38.73 MPH
2nd: 1.98....66.12 MPH
3rd: 1.39.....94.18 MPH
4th: 1.00.....130.91 MPH
5th: 0.82.....159.64 MPH
6th: 0.75.....174.55 MPH


amazin, huh? all from a little 340 CC motor. Those speeds are at 6000 RPM, while the redline is from 7200-8200 RPM.

Here's another one:



It takes the power of a 2 stroke, mixes it with the added power of a HEMI cylinder Head, and finishes it off with dual spark plugs, all meeting the above 340 CC limit. If you can see all the little red dots, the space between each red dot is 1 inch. So it's a fairly small motor. I didnt go into many details. Everything is to scale except the spark plugs. It's based on the image in the next post:

I found an error: i mis-expected the TDC posistion of the piston, and had the heads at the wrong place. As shown up there, it had 4.2-4.6:1 compression. I redesigned it so that it has 18-20:1 compression.

Got race fuel?

I guess the best thing to do with all that engineering, would be to build a WORKING proto type, and RUN IT. then post pictures and results, from THAT data. Otherwise, it's just theory.

everything in the design is already used.

HEMI: Drag racing, newer Dodge vechicles
Dual Plugs: Drag Racing
2 stroke: well duh....

I would build it but i dont have access to a CNC machine...nor does my dad.
