2.5 drag timing

[Wild Bill]

Can someone tell me how many thousands before top dead center 25 degrees is. I can't remember. It would be nice to not have to get out a degree wheel and figure it out myself.

25 degrees = 150 thousands. BTDC.

Is there a chart available showing how many thou per degree? Im aiming for 23

[donmac]

why does 462 come to mind, been a while was that the dial indicator setting from tdc for pointer adjustment?

I saw a pic of one someone is making for the 2.5L flywheels. It is a magnetic round with all the timing marks on it for each cylinder. Looked badass. It was motor specific though.

I wanna know what timing people set F1/drag motors at when they lock it out.

[Wild Bill]

I thought they locked it out at max timing

[25two.stroke]

Max? Like 25 deg. ?
20? 30?

I've read 25°, but I've also read where some of the drag guys won't say. I would guess they are closer to 30°.

justa hint.... "COMPRESSION/FUEL"....................

sometimes ya bump it up and sometimes ya bump it down.....

Makes perfect sense.
How nice would it be to hit a button for a different tune!

Buckshot racing...thats it!
That wheel makes me wonder if they did it right or not. Is each cylinder TDC accurate or did they take #1 and then just cut the whole 360 deg. evenly into 6 pieces? Cause the crank journals are staggered slightly this wheel could not be accurate or it could be. I hope they took the time and did it right so each cylinder is timed accurately. Its a nice piece.
