all it does is spin huh... maybe you shouldnt go lower with it.
you need more speed not power
bigger front, smaller rear = speed
smaller front, bigger rear = spinny

after you said you spun too much with 45t rear, i figured you had not known the ratio differences
go with 14:40
or even 14:38 with those 18"

We used to run 12:40 with a stock piped engine.
After fitting a KOR ported top end and hemi cut head, my lad took it for a run on bitumen and came back and told me he had no time to change gears.
We will be going back to 14:40.
Word of warning change sprockets and chains and make sure they are all new, especially with a 12 up front.
Chain breakage on mismatched chains and sprockets is all too often with disastrous results.
Dualstroke is the guy to answer your gearing questions, he is the drag guru.

I would do yeh, depends on if you cant shift fast or keep the revs up.
play around with this

try different sprocket sizes and tires.
I wouldnt want to try anything over 65 mph because you still need to be able to start without a slow clutch let out
dont change the gearing ratios, they are blaster specific.

With gearing that low you could run 25s 
Tires are deffinately the problem.
FYI, Sprocket Specialties will make any sprocket you want.

I have a nice lone star ex swing arm on it th
so 22s would be ok with 13t front and 42t rearWith gearing that low you could run 25s

You can run any sprocket 39 teeth or higher on a blaster. Just not sure who would ever use a 51-52 tooth rear sprocket on any blaster motor
14:46 and whats your top speed?
i dont care for much more than 55, but sometimes you need a little speed

240 doesnt mean its set up for rag racing...

on 12:52 gearing with 20" tires
You will hit 40 mph in 6th gear at high revs...
good luck racing
u do remember drags are 300 feet..... right?? hes probably not going to reach top speed in that distance
