What was the old engine mount height when the 35.7 mm diameter flywheel fitted fine on the stock chassis?

Data

the bottom surface of the two mounting flanges on the enigne lines up with the center of the shaft. for a set of 14.5mm tall engine mounts and a 3mm chassis, max. O.D. of the fly wheel is 35mm for it to work without any problem. i will cut it down to 34.5mm just to play it save.

The height of the old engine mounts are 16.7mm high. I guess you could take 2mm off but do you have to allow for knurling the flywheel.

InitialD

To get it to where the flywheel would be with reference to the chassis when the new engine mounts are used, you need to take off 2.2 mm off (16.7 - 14.5) from the radius of the flywheel. So your engine flywheel should have a new diameter of 31.3 mm (35.7 - 2 x 2.2).

For the flywheel of the starterbox to crank the engine flywheel properly, you may have to open wider the flywheel opening hole in the chassis. Just double check.

Thanks InitailID for the help

will the hpi .12r ss fit on the v one r?

HEYALIGNMENTGUY

Yes, if it is the non pull start version, Don't forget the Kyosho side exhaust manifold

Any idea when the EVO RR is going be released?

Soon it's all ready released in Japan

Yeah . . the only bit that annoys me is that we are supposed to get a lower CG with the lay-down servo, then promptly give it up by having to use the standard fuel tank.

. . . . hope the front mods work out - we'd be happy to get a bit more steering, also.

The tank is not a big deal when you look at it really. The Mugen and Serpent tanks "look" lower but in fact they have a quite high CG because they have cutouts for the battery underneath them. The fuel sits quite high in both of these tanks because of this hollow, so while the Kyosho tank looks high the CG is probably quite similar. Also the V1R tank is centred unlike the Mugen and NTC3 so the overall effect on polar movement is less.

Taylor-Racing

Yes, your right. I guess I'm just bitching because I'll need to provide the budgetry requirements for a new tank.

Have you had a close look at the new front geometry?
I'm wondering if it's going to correct the F/R geometry changes caused by using the overdrive pulleys and the consequent smaller front tyres.
Any thoughts on this theory?

Hard to say without looking at it in my hand. Longer arms make the car more stable and less prone to roll/pitch. If the upper arm is shorter it will affect the camber change and if the upper arm is more angled it will lower the roll centre. That is all I can say for now

I must say that I am routinely now using lower shore tires on the front and softer front springs than rear (eg. black front and rear rear) This is mainly to try and get the car to turn in hard (note I am going into corners pretty damn hot without brake usage) More front bite I think will balance this car out rather than more rear bite. My experiments with the M1RR rear end proved to be very successful in some ways (rear was more stable in some circumstances) but it actually removed a lot of steering from the car exacerbating the slight tendency to understeer. Bring on the EVO!

Taylor-Racing

Hmmm . . I thought that both upper and lower EVO arms were longer.
Ahhh, I guess we'll really need to see it.

On the set-up front, we haven't used the M1RR rear end yet, partly because there are so many other things I wanted to try in order to get a proper base line. I think I mentioned that I couldn't get the super hard Fantom springs to work for us, and I dare say there are track differences underlying part of this.
We have seemed to have settled on black front and gold rear springs, lately, for Lilydale - some of this was intended to kill a bit of rear grip and, thus get some more steering.

For tyres, we also run softer fronts than rears, and yes, this gets the desired steering. Interestingly, the F/R balance seems better and more forgiving, also. In fact, we ran 35F/35R at Lilydale last meeting, which was a bit OTT but the grip obtained was tremendous, though tyre wear was worse, as you might expect. We run Active tyres, and they seem more forgiving of a "too grippy" tyre choice and the weather differences in Melbourne are more marked than Brisbane and this would account for part of it - the last meeting at Lilydale was only 14º C or something.
With this grippy set-up, I run less rear toe-in (maybe only 1.5º) and it keeps the rear more progressive and less "snappy" - helpfull when you really do have too much grip.

We're also running the car higher than usual - 5.0 front and 5.5 rear, together with more tightly limited droop - I'll need to take a measurement.
I'm pretty happy with this set-up even though it seems a bit strange - and the Mugen's don't seem to have anything on it, any more.

Hey, what about some weekend race reports, guys?

Not much news from me . . . we went to Castlemaine, all fired up . . . RAIN AGAIN . .

. . . but the Mini Z pool was a lot of fun.
OZDC showed all how it is done.
