No way a blaster with only those mod be competitive to a 400ex With only those mod u cant have 27 hp and the stock power of the 400ex is 29 hp at 7000 rpm

 

Well I dont know about the 400ex, but I haved smoked every blaster that has tried to race me on my z400. Yes you do have a weight advantage against the 400ex and your hp is close to his, but... you have way less torque. This will make a difference in holeshots. Are you running paddles? If so, you will have to fun fewer paddles than the 400ex, thus less traction upon take off. All I can say is good luck, and practice your take offs. You only chance is to get a good holeshot and keep it pinned.

 

Why don't you all just g out and get a z400 LOL. Just as much as a 400ex and 8 more HP stock
