Superjet engine in x2

Location
V-town
62t, SBN 46 single carb- coffman pipe cut 3"(bought it that way) - stock water box, stock head, stock porting, c 75 9/17 (beat up a little bit) bored x2 plastic nozzle

The 750 makes more HP, but its when it makes it. This little 701 hits hard right from off idle.

My main riding buddy just did a super fresh small pin 750- ada high comp head (91 oct)- sbn 46, vforce reeds, westcoast exhaust mani, coffman pipe, coffman water box 8/16 c 75 with a stuffer, 87mm pjs ripturn nozzle and MSD 750 electronics and a newmiller lightened flywheel.
His ski has 1-2 mph more top end than mine. I take him off the line every time- and I weigh a good 40lbs more than him.

So it really depends on what you want the ski to do. I am floored by how hard the little 701 hits.
