Thanks guys, good info on the overdrive issue!!

Next question

Can somebody explain the differences between the Nova Rossi S1, S2 and S3 engines and parts interchangeability.

This is becoming confusing and the NR website dioesn't provide any insight.

Thanks

Talking More Overdrive talk!

Recently had a small chat with another member of this thread (here's a hint: his handle starts with a P and ends with a T)regarding overdrive for an MRX-3. I thought I might post his reply because it applies also to the MTX-3:

My q:
Recently I began using the overdrive 25T pulley, but I think I may be stressing my front belt more now than before, because I've been stripping teeth lately. I normally run with about a 6mm split. Should I be using a different split with this pulley? The car doesn't seem as out of whack handling wise with the overdrive pulley in comparison with my sedans, but the stripping thing is bugging me. I've even got a front belt tensioner on the car that I devised, but it's not helping right now.

He replied:
"...regarding your MRX-3, great car! We have been running these for the last 1 1/2-2 years and I have to say it is one of the easiest cars to build and work on that is on the market. Running the 25T pulley allows you to run smaller front tires i.e. larger splits (@9mm) while still maintaining an overdrive ratio of 1 (aproximate numbers here). The reason that you would do this is primarily that it raises your roll axis on the front end. Raising the roll axis means the car stays flatter through corners puts more weight on the inside front tire when cornering which is not necessarily bad as the outside tire is being loaded by the G's of cornering so it argubly makes the car corner more efficiently. Having said this, when you start talking about roll axis things are getting realy complex and it's difficult to do without drawing out diagrams to show the geometry of the suspension and how the pivot points intersect. This is best done talking face to face with some one. However I hope this gives you an idea at least of what running in the case of the MRX-3 a 25T pulley and on the MTX-3 an overdrive pulley does and why it does it.

Regarding the belt stripping you probably have an overdrive chart for the car. If so then looking at it you should be running about a 9.5mm split. With anly a 6mm split you are running a massive amount of front overdrive (basicaly off of the chart that I have). Try running something like 74/64.5 which gives you a ratio of 1.004 to start. Also try running a couple of washers or shims under the mid bearing block to raise the pulley which should tighten the belt a little."

I've been schooled...

Cartman mentioned about how to avoid the tank from leaking. He said around the fuel tank area on the upper deck, there are 2 round edge which could cause fuel tank leakage when crash. you might want to file the round edge by 0.5mm (YES 0.5mm) to give more clearance for the fuel tank when crash.

as for mending of a leaking fuel tank, use a soldering iron to do the job.
Thanks heaps manti, u know your shit

I asked rody on the RB forums and he said with 20% it should be fine to not add a shim but if i wanted to go to 25% i would need a head shim

and i will remember when im building the kit to do that little fix so i dont bust the tank

Here a thought.... If I can get PMT to set up my car, Dennis to tune my motor and Kevin to paint my body...

Manticore.

While it's true info is out there...PMT seem to have a way to make basic info basic...

RCLover

Kevin
