It will break 70 in 660', I have been drag racing in DSRA and AOF. Was suppose to make all the ODBA races but didn't. Jack Barsh built mine. The 90 is a .020 over and will spin a 20p Yamaha drag to 8000. It is quite a blast. I have seen 79.1 with a big prop. After Jasper it will get a bottle.
The 3 cyl class has been accepted into the clubs. The clubs have joined and have parallel rules across the board on every class. The 3 cyl rules will be posted on the DSRA site real soon.
