I was wondering how much $ it would take to make my blaster go about 75mph and faster

 

um ct 240 kit with 41hp 14/38 gearing and 22inch tires that should about do it
75mph is a lot for a blaster so good luck....

 

why 22 inch in rear or front

 

i think it is bigger tires = more top speed ? i think

 

Correct Dirtrider.

 

yah bigger tires increase top speed

 

what about little tires

 

Bigger tires will also be harder on the low end, which is why Toomey is suggesting gear and engine changes. Smaller tires will be faster at low end and lose top speed as you work through the gears.[img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-cool.gif[/img]

 

k changing tires sizes is almost similar to changing gears. a smaller tire such as a 18 gears you down meaning more bottome end but less top speed. gearing up with a bigger tire decreases the bottom but increases the top end. now tire size and gearing actually have more of a difference in the top speed then mods does. of coarse this is only not alway true and its not like mods do not increase top speed. A pipe increases the top speed because it revs higher allowing a higher speed. However to get the blaster to even pull a 14/38 gearing with 20inch tires well you'll need more power meaning mods. however with a 240 kit i'm sure you could pull 22inch tires wich would increase your top speed. so as you can see the more power allows you to pull higher gearing or bigger tires to increase the top speed. Also just incase you didn't know stock gearing is 13/40, so bigger on the front and smaller on the back is giving you higher gearing. but i'm going to warn you 75+mph is going to take a lot of money. we had a gun on mine ice racing and it went about 55 with a pipe 18inch tires and 14/38 gearing. i'm not the expert but i hope that explained a bit.

 

btw a lot easier way would be to sell it and buy a shee....
