Today was race weekend #2 on the SD and boy I was in a funk! Got it handed to me today. One of those days where the harder a person works the slower you get...lol I am running a dual diff car at the moment. I am really strugling to get the car to turn in off power...that is killing me. I started of with most of Mo's sheet from speedworld...minus the spool. I tried 7 droop front, pink then orange springs, rear tower on front, 6 droop in the rear, moving bottom of front shock in a hole and nothing would help get any off power steering. Took sway bars off...man tried a bunch of stuff...lol I have always thought I could tune but the car beat me up...lol Running on med to low bite concrete with some pretty good temps. Any and all tips would be great! Liked the car week one and thought today would be the day...did not turn out like that...let the help flow...

[B]Which of the three MIP CVD types do you recommend for the SD?

Aluminum, Shiny or Standard?
Are the the ones made of aluminum durable enough or do they bend easily?

hope it helps,
I noticed some people mentioned they were using larger gears altogether. Earlier in this thread somebody said he was running a spur with 110+ teeth which is around the maximum the chassis will physically allow. Benefits?

110 is a 64 pitch spur, whereas 70 is 48. The only benefit of a larger spur is that is will give you a more usable range of ratios - with the standard 70 you can't fit anything much smaller than around a 23 pinion - so if you're running indoors or with a hot motor, you won't get the ratio you won't. I run a 75 spur, and I've got a 19 pinion on.

As far as any weight distribution aspects, I would rather run gearing that keeps the motor closer to the centre line, which will decrease the torque steer effect. Although a further out motor will help the side to side balance with 3300's...

I was wondering what spur do most guys run when running 64 pitch gears? I have seen a few sizes from 95 to up to 110. I normally run stock?

I'm running a 10x2 motor, and a 20T pinion with the stock 70T spur.

wyd,
We run a 96t spur.

Just bought a pair of MIP shiny steel CVDs for the front after breaking another axle. They seem to weigh about the same as the stock units and should be stronger, especially when using a one-way. The ones for the MR4TC front fit fine.

Hi guys. greetings from Malta.

WYD.

Nice to see you back.

I run a 94 spur. This saves me changing spurs between 12 turn mod motors and 21 turn stock. Pinions - 34 for mod, 44 for stock.

I agree that a smaller spur helps keep the weight more central, that's why the 94 compromise.

As far as breakages are concerned, I have now had 2 really big crashes. The first, which left a big dent in a brick wall, cost me a front shock tower........and the race. The second....NOTHING. Incidentally I am using the old Yokomo alloy drive shafts all round and have had no problem to date despite running at least 3 packs practice a day and 2 full race meetings - both wins.

Regards

Joe from sunny Malta.

I don't know bout you but running a monster motor at that ratio does me no good.After talking with a few motor tuners and Chris Tosolini.I find that running a good! monster motor in the 8's is the ticket.My motor feels warm but not hot enough to toast the com.The comm usualy cuts the fist turn and brushes never look scorched.I know what u are thinking.Just try it it works.And most people usualy say you're cheating and running a 19 turn.

7.0-7.1 is just a starting point for gearing SD, for a relatively small track with very short straightaway yes i will gear my SD around 8ish . My home track is a medium size track with straightaway about 90-100, 7.1 will be perfect.
