17/47 or 19/47 ???

[Jeff@TheNetherlands]

I`m running the stock 17/47 gearing in my SS with K4.6 motor and was wondering if anyone has experience with the 19/47 gearing setup. Can you still wheelie from standstill with that setup?

My ideal would be to be able to wheelie from standstill but have more top end speed than with the 17/47 setup (I find top end a bit dissapointing, low end grunt is very nice).

Oh hell yeah U can much easyer I had to softin up my rear shocks a little cause to much wheelies but I can still pull them easy but I went both metal and the racing clutch bell with the vents. Top speed is a lot more but I also have the 3-speed trans so that also might have something to do with all this.

I have not found a gear set up that my hpi 4.6k wont wheelie with......lol

go for it bud.

Hey Jeff, Do you have a 2 speed or 3 speed? What tires are you running? these also make a difference in gearing and what cb/spur you can run. Personally I have found the the 16/47 or 17/47 to be the best overall performing combo with the 3 speed on stock size tires. If you go to tall on your gearing, it can actually hurt your top end. Meaning the engine cannot pull to much gear once it passes its torque curve, especially with stock mill. Now saying you put a more powerful mill in, you could definitely jump up on the gearing.

19/47 is too tall of a gear foer the mill to handle over a period of time. I would go no bigger then 18/47. Get the 3 speed tranny upgrade to the taller gearing

Hi,

this is probably what you will want to try if you have the 3-speed trans, http://www.horizonhobby.com/Products/Default.aspx?ProdID=HPI77065

it is for higher top end, you will only be changing the the gears that effect 3rd gear and not touching the 1st and 2nd gears.

I don't know if these are available or if they are just sold out everywhere, but for th parice it is worth a try.

here is the link to them on HPI's site http://www.hpiracing.com/products/en/77065.html

i run 17/49 with my os, liked it better than 17/47 plus gained a little speed

[Larsenracing]

I don't know if 19/47 is a good choice. You will loose alot of bottom end as you are going to 2.47:1 gearing from 2.76:1. It may lift the wheels yet but im not sure what you all do. If you race you may want to stay 17/49. The Savage isnt ment for speed. You can try it and see what it does. CB's are fairly inexpensave. Good luck.

Im running the 47 / 19

it wheelies in the power band not off the line, it will flip over on its lid in the powerband if i dont back off

[Larsenracing]

There is no dought in my mind that it wont wheelie but you will loose a quite a bit of low end power going with this gearing. As for me it would never work as i really like to climb huge sand/rock piles and want good power but not to much. I really like 17/49 which is 2.88:1.

[Crash]

my other savy 52 / 17 = 3.05 I have run the 52 / 15 but, alittle too low. lol

talk about lowend power it is sick

[Shaun]

man im still learning new things! lol im still running the stock gearing that came with my 4.1 which is 15/49 and it wheelies nice lol

my truck came with the 18t clutch bell as a extra in the box so im just curious how that setup works (18/49) anyone run this gearing?

[Larsenracing]

I tryed it right away. I liked the gain in speed. but missed the low end power, the truck would still lift the front wheels off the ground. I decided to go 17/49 to be in the middle. It worked great.

I have run the 17/47 (stock), 17/49, and am currently running 18/52 with the 3 speed.

The stock X gearing (17/47) works really well.
The 17/49 offers a bit more low end with a small sacrifice to top end.

The 18/52 with the 3 speed has INSANE bottom end
(requiring some suspension tuning) with a top end comparable to the 17/49.
If HPI ever gets their high speed 3rd gear setup out, I am guessing I can match the 17/47 top end, while retaining the crazy bottom end torque.

[Larsenracing]

I believe the stock X gearing is 16/49, The later kits like mine came with a 18T CB just thrown in along with aluminum Diff cups and a few other extra parts.

[Double-O-Zilch]

My X came stock with 17/47. I have the RTR version though. I dig it but I need the 3 speed! Hopefully the high speed setup will be out by then.

[MotoPsycho]

The stock X gearing (17/47)

Sorry, this is stock on the 4.6X RTR

[Larsenracing]

O ok your right I was refering to the F4.1 RTR version never even thought about the new 4.6 RTR.

What you need is a engine block .... lol sorry had to say it

[Shaun]

my x 4.1 rtr came with 15/49 gear setup as stock!!! thats weird !!!!

[Larsenracing]

my x 4.1 rtr came with 15/49 gear setup as stock!!! thats weird !!!!

Gee sorry my bad, I cant believe I did that. Thanks for correcting me it is 15/49 for the F4.1 RTR, I just ran down and looked at my old CB.

[Shaun]

to be honest i went to check as well cuz i thought i might of been wrong!! lmao ya that gearing has awsome take off and wheelies but u loose top speed!! but im never on a track or anything so i dont need the extra speed!!!! thats why i havent put the 18t clutch bell on that came as a extra in the box!! lol
"gotta love them wheelies............"

[Larsenracing]

I may be going back to a 15 or 16T CB as I have recently put on the FLM Extended chassis, but ir really depends on what I do with a motor from here on.
