Default At what point are we too big bore?

I am curious, at what point do we hit the sweet spot on "big bore" shocks? Or, are we eventually going to be running LST shocks on our Buggies?

Curious, anyone try that?

You know, i wouldn't doubt that shocks from a Honda Civic would fit on a Truggy, hell, Civics are practically toy cars anyways!

Bigbores are a cunning way for manufacturer's to sell more shock oil, I am not convinced they are any better than standard shocks. Going any bigger than 16mm is definitely a waste of time and would just add weight.

the only thing LST shocks are good for are Tank like MT's.....LST's Savage's Cen's.

Xray XB808 with LST shocks coming soon.....

That would look freaky....

Hey do they have softer springs for the LST shocks.....?

I think there is some merit to a big bore shock set....more oil volume means longer for the oil to heat up and thin out while the greater surface area of the body also helps with heat dissipation. Those I know who've run big bores say the only place they see any real gain is on ultra rough tracks late in long mains which tends to support the above.

Increased oil volume is also a very neat way to get a noticeable change in shock action by simply going up or down a few points on oil viscosity rather than the time consuming task of actually tuning your shocks by reducing stiction, playing with piston hole sizes and oil/spring combinations, etc.

If you subscribe to the KISS principle, it's a much more practical solution to more consistent shock action over long run time duration than the remote reservoir concept, but I also think shock size will (if it's not already) reach a point of diminishing returns due to the added weight, but this is America, where if bigger is better, MUCH bigger must be much better. Time will tell if the big bore concept moves from the practical to just another marketing tool designed more to hook racers on a car than hook cars to the track.

I guess until shock systems employing oils which change viscosities in reaction to electrical impulses like those being used in top end 1:1 off road racers become practical for toy car use, big bores (within reason) are the simplest, most cost effective solution to mass production of prebuilt shocks that actually work.

thinking on this idea, big bores thinner side walls more susceptible to outside temps, plus once the oil has thinned theres no extra material to transfer heat or maybe the thinner side walls will work faster, standard shocks possibly thicker walls maybe not if they do better heatsink and less prone to air temp plus a std shock if designed longer in the body can hold equal amounts of oil also but still have the advantage of more material, who knows as for the original question i think any bigger will be silly really

I saw a set of 17mm big bore shocks. They were being sold on ebay.

Big bores made me 1/2 second faster....................




In the 40 yard dash................




B/C my pocket was lighter!!!

lol
Actually I will get them for my rc8 soon. Gotta pay to play,
and I doubt anybody will just let me borrow them to try out.

Thinner walls also mean weaker shocks more prone to being damaged in a crash.

I personally have never seen a shock body damaged from a crash. Its normally the tower and shock ends that give.

I went from 13mm shock on my mbx5r to jammin 16mm shocks. I noticed that my car felt more stable later into 20 minute mains. It didn't seem to bottom out as easy, and was more predicable. Here it is easily 100 at 9pm, so the heat is an issue. With the 13mm i was running the 1.4 pistons with 650 oil, but with the 16mm, i can run the 1.4 with 450 and keep a more consistent feel.

You should temp your shocks after a 20 minute main to see how hot they are. Compare it to a temp before you start running.
