Mmmmmm Big Bore Shocks!
 

Just seen Jimmys The Players pre report and see the new big bore shocks and springs!

They look superb! When are they out??

What performance gains will they give? I suppose being big bore you have a larger volume of oil so you can run lighter oils and get a different pack to the shock?

Tell us more!

don't they just look the snizzle, will be down at the players tomorrow spectating for a while and if allowed will get some sneaky pics,

See the pics in Jimmys report! New wishbones too!

It's good the team keep developing the CAT rather than Xray who bring a new car out each year!

In theory, if all things are equal the shocks characteristics shouldnt change too much.

A large shock capacity will help with greater consistency and the oil not having to work as hard therefore lasting longer and requiring less maintenance.

But with new pistons shapes, number of drilled holes, as well as revised springs, I think that some fine tuning will be necessary to get the best from them.

I'm more interested in the tuning springs tbh.. where can i get those from? I like how the weight is etched into the spring.. are any available for the standard shocks?

None of the big bore shocks or springs are avaliable yet.
They are being tested and will be out when they are happy with them.
We all want a set, but only an elite few have had a go, the rest of us must be patient, haha.
And no springs like this have been made for the normal shocks as far as I know.

/sits and waits.

apart from the ones you get with xray tc they have the rate stamped on them the taper is to clear the lower arm seems a bit of a bodge if you ask me.

stu

Run losi shocks....

Stu runs a B-Max now, just ignore him!! :p

Only kidding mate!!!

Not an option for some I'm afraid.......

After seeing the shocks in action this weekend I am very impressed and looking forward to getting my hands on a set. Si and Grant's cars both looked planted, the cars could get over the rumble mat section alot better than most. It also appeared to help the landings from the big jump.

It's hard to tell of course by just looking but both drivers and mechanics were positive enough through their comments concerning the testing, there is still some more testing to do and I'm sure we'll be hearing more about them sooner rather than later

When they are released I'll get a set and try them out, until then Losi threaded shocks at our track.

was si and grant running taperd pistons?

No, the tapered pistons are the next thing they'll try - if they work then I'm sure they'll be included.

Both the drivers seemed to love the new dampers and said it made a real difference.

would be intresting to compare losi springs on them for me the losi springs felt more consitant

I like playing the shock game...

knowing almost nothing about the size of them etc...

a stab in the dark here

6 hole pistons in the front equiv hole size to a Losi black piston, 40wt oil, black springs :P
8 hole pistons in the rear equiv hole size to a Losi black piston, or maybe 6 hole red/orange equiv, 30wt oil, black springs :P

dialled... maybe, I reckon I will be spot on with the springs at least

either way, big bore is the future!

Exactly what a friend of mine says. Losi springs are the best that I have come across.

3 months before we can get our hands on these Big-bore shocks after an email from Schumacher:cry:

the shock never pass the wishbone, dont think it does on any car,the spring taper is so that the std spring retainer can be used im guessing,a large flat sring retainer might catch the wishbone,

i wanna know what size they are.....................

internal diameter?????????????????

they looked to be bigger than the yokomo big bores so im guessing 14mm

what are yok ones????????

im doubting 14mm... 8th big bores are 16mm!

yoko ones are 13 or 13.5mm

Sounds amazing Chris - like your style :thumbsup:

Schumacher Racing have some interesting new development parts on their 4WD cars - sadly the new 2WD was swiftly taken away after some secret testing at the nearby RHR race track facility and won't be run this weekend. We were told by a little birdie that it's as unique as the CAT SX was when it was released.
The big bore dampers are the 'biggest thing' on the cars - and only the top team drivers had the chance to run them this weekend, with only three sets in existence it was a bit of an exclusive club. The dampers are large - possibly not as monstrously humongous as the Yokomo big bores, but maybe that's not a bad thing.
All the springs for the new dampers are black - but helpfully have the weights etched into the top shoulder. The springs are tapered toward the bottom to clear the suspension arms.
The team also have some new suspension arms to test out - and our man Graham 'blitzboy' Smith was one of the few drivers with them, and is sure to give them a thorough strength testing! ;)

highlited in bold!!!! my yokomo shocks dont hit the lower arm and neither do the yokomo big bore as they use the same springs and retainers like i said it seems a bit of a bodge.

Hows it a bodge? I simply don't understand your point?

Since when did the Yokomo big bores use the same spring and retainer? Do you actually have any or are you trying to prove a flawed point?

i dont get the bodge either.

Surely it would be cheaper to put longer ball studs on the wishbones and shock tower to get the clearance, rather than design a tapered spring?

because the springs dont fit the car without being taperd as soon as you change spring diameters it changes the spring tension why cant they simply mould a stand off on the lower arm and use bigger spring retainer and have a true linier spring dony get me wrong im not slatting what they have done just a mere obviouse thought.

Don't get 'bodge' from the perspective that there's no 'bodge' to get? Or are you of a similar mind set? :lol:


Longer screws - ? The closer the shocks are to the wishbones / tower the better. Otherwise - you use the shocks as a bumper, you bend screws, you smash wishbone mounting holes. Using longer screws is a bodge if there ever was one - designing a tapered spring is a smart move, the opposite of a 'bodge' if you ask me. :confused:

No idea what your point is tbh - these are new shocks and new springs. They DO fit the car as you can see? I'm not sure what the problem is. I'm sure they could have made them so they didn't fit and then had to also redesign the entire suspension and drivetrain - but that seems a little silly.:lol:

i stand corrected yokomo big bores springs are diferent

ok let me re fraise this what is the point of putting a taper on the springs and changing the liner profile the spring for the sake of a larger spring retainer and a small amount of plastic moulding on the lower arm no longer screw.

there is no problem jimmy just an obsivation they do fit they say they work and work well and will probably inprove the car which is always good.

Ok, turn it around - why do all that instead of tapering the spring?
Seems like a clever idea to me and I can see absolutely no down sides at all!

except the liner quality of the spring under compresion.

which means when the spring is compressed it compreses at the same tension until the coils become closed which is a major part of how a spring works dont you think

theres more than just liner type spring,theres rising rate and progressive which all have uses and may be the taper is there for more than just your wild guess at missing the wishbone,

yes you are correct but it was not a wild guess about missing the wishbones it clearly says it on the write up obove the pictures so from the information given a linier spring would be the more likly.

i think its clever..........................

Well done schumacher. Not bodged at all.

Yeh, but that's just what Jimmy wrote, and he's not the designer so who know's. In fact he's a bit mad really, and could easily have written - "The spring tapers so that it has more clearance to jelly when racing on that surface." Would that be true also :confused: :lol::lol::lol::lol::lol::lol::lol:
