I have a savage 25 swapped a lrp.30 into it the gearining is 19/47 i used a garmin gps and i have a top speed of 45 i want to get more top speed anyone Know a smaller spur gear that will fit ive seen ppl run the flux spur but not sure how to get it to fit any info will be very helpfull ps on my current gearing i am able to pop a wheelie when ever i want so i still have a lot of room for top end

What tranny are you using? You need the 3spd with the optional high speed 3rd gear.

There is nothing special needed to mount the 45,44,43t flux spurs.

Heres the catch with trying to go fast...... You need torque. Yes the LRP 30 has torque but its not enough imo.

This is what you need to get your truck fast,

BP 3spd w/HS 3rd gear
Flux 44t Spur
19 or 20t clutch bell
Flux/ XL BP diffs- lowers the gear ratio making them much better for top end unlike the stock 43/13 gears
A nice low snug fit body
ERCM endbleed pipe...... trust me on this
Hpi Phaultlines that are belted

Good luck and Im very curious to hear what you reach

I have the 2 speed I wasnt sure if the spur gears on the 3 speed were mounted different because the owner of my local hobby shop told me that there is no way it will fit .
I think the lrp.30 has enough torque imo
I happy with a top speed of about 55 so i think the lrp.30 will get me there in modded i already have that pipe
and im using e revo tires
Im going to buy the new spur today should i go with the 43 /44//45

My truck is one of the first savages it is barly a 1/8th scale i weighed it and im about 9.3 pounds

The flux spur will fit on any of the savage trannys, there all the same mounting style

Try the 43t spur, but your going to need the 3spd tranny

Good luck reaching 55

Do you have the spur set up that uses the dual slipper assembly? That's the only way that the flux gears wouldn't be compatible.

bertinoj

alright i bought the 44t supr because thats all they had at my hobby shop it fit fine i will try for some speed runs tomorrow if everything is good hoping for around 50
i was doing 45.6 with a 47t so how much do u think a 44t is goood for how many more mph

llkoolskillet

you gain more MPH when you change out the clutch bell vs the spur gear.

Your truck is going to be geared even higher thus resulting in loosing rpm up top. I have a feeling that yor going to actually loose speed

bertinoj

what do u suggest i do?

llkoolskillet

Get the 3spd if you want to go faster IMO

bertinoj

HIgh speed needle and low speed needle
The low speed is right below where the throttle linkage is
the high speed is the screw coming out of the other side
