So did he explain the difference in the car reaction between the 2?

Not bad D

I have tried various car setups and tire combo's with the 16T and I found softer springs are the best for this combo, but I can get faster lap times with a 17T and Harder springs.

I do run soft tyres at my track 35 speedminds on front 37's or 35's on rear depending on the grip on the day.

Guys

Sparksy is correct it hit on both our cars and my friends as well.
When i installed it last week I spent all day checking the car over to work out why, as sparksy has said it is nothing to do with the steering throw. For some reason the new part must sit slightly lower than the old one, but it is a very small amount to cut.

No doubt lower front roll center gives more on power steering but higher front roll center makes the car's transition changes from left to right etc better.
Exactly D. This is what I have found as well and what I have been saying. I also run the high front roll centre and the car feels fantastic IMO

All that is left to do is find the best dampening combo (spring and Oil). Your running Red and Yellows arn't you D?

So Pyramid, this is a good point.

As a guideline, what oil do you use for which springs?

The kit comes with 30 - Yellow.

Following on from my previous question, isn't the 35W Serpent oil more suited for the Red springs?

Trinity 40WT is the equivalent of which Serpent oil?

Sow, I've been running 16/61 for the past 20 tanks without stripping or modding. I can't seem to figure out what i did wrong in the past but it seems to work fine now.... Mebbe it's better meshed with a smaller 2nd gear pinion. 16/61 and 21/56 is my current combo. Oh yah, I've tried it on both blk and bronze pinions and they both work....Strange but true...
Crashed, I must say that I did have one particular set of 16/61 that went on for a while but finally the 61 stripped.

As for the smaller 2nd gear pinion, that's what I used anyway. Always 16/21 and 61/57. So I don't think that
s the issue. I think Julius expalined it best ... its got to do with the 16 teeth being on a larger than ideal/optimum diameter.

I just looked again at my new set of pinions and gears ... when the one tooth is perfectly centered on the spur, the next tooth on the pinion is actually not quite in and "rubs" a lot as it tries to engage the next tooth on the spur.

One can imagine that at high speed, AND when the pinion teeth is sharper, the tooth will bite into the spur tooth and starts the stripping sequence.

This therefore explains Pyramid's solution of meshing the two as lightly as possible but moving the engine further forward. Remember ... his mode elongates the engine mounting holes towards the front of the car.

Correct ... its different because of one word .. its called "pack".

Onkel Sow, if you have to use 16T pinion, you could use 16/60 combo which gives 7.03 FDR. 16/61 combo gives 7.15 FDR. You will note that if you want to get the same rollout as using 16/61 when using 16/60, you need to use 1 mm smaller tires all around when you're on 16/60 to achieve the same kind of acceleration.

Yes, actually I tried this. I found that for my previous set up I had to use the same shores all round and this split did not last. At some point the split disappears (rear tyres worn more than front) and I find myself losing time.

Recently though I've found the setup I like with the front on softer shore than the rear and this split lasts longer. I should therefore try your suggestion,

Quote:
Making 61T larger would defeat the purpose I think since you'll have meshing problems with other 17T and 18T 1sy gear pinions.
I wasn't implying that ... I wa merely making a suggestion. Look at the previous to this one (I was answering Crashed). I've not seen what Julius means ... the 16T pinion should actually be on a smaller diameter body altogether. The current diameter is a little too large.

Restecpa! That's what I thought too. Actually old Desmond once produced a chart he found somewhere and it pretty much showed that the Trinity numbers are double that of Serpent's if I remember correctly.

40Wt Trinity is closer to the equivalent of about Serpent 20-25Wt.

OK, I'm not sure about your driving style but my local track has a fast chicane. You can see many videos of it at my site 3hobby.com.

To get a fast time on this track you definitely need to be able to transition quickly on this chicane and for me the best I've found is to use 35Wt on Red springs all round. At the moment I'm on 4 holes (stock sized holes) in front and 3 in the rear.
