I am going to finish modding my blaster tonight, and am wondering how much power increase I can expect. It has a full fmf exhaust already, and I have added a K&N air filter, v-force3 carbon reed kit, and a 28mm d-slide carb with custom jetting.

 

That is about the same setup as we have on our Blaster. Ours has a Pro Circuit p/s and G3 reeds and a round slide 28mm carb with Uni filter. The reeds will help with the throttle response more than over all power. The pipe should be the biggest power adder, which I think yours is more towards the lower end. I honestly don't know if the carb really helps that much but it sure doesn't hurt. (on a basicly stock Blaster) I would also run without the air box lid unless your in alot of water. Overall I'd say your going to gain 3-7 hp over stock. Its not going to be earth shaking, but it should be noticeable.

 

I think the pro circuit and FMF Pipe are pretty close. The 28mm carb adds lowend power and throttle response. &HP is a big gain considering the stock output of the blaster. I think you will be pleased with the results. You also might want to look into a degree key or advance the timing yourself, and milling the head for increased compression. THese are cheap mods that will compliment your other mods.
