You are only allowed to use 3 engines during the Worlds, which are sealed by the tech inspectors. If you want to repair the engine, they will remove the seal, you repair in front of them and the reseal it.

The only two engine rules left are basically displacement and number of ports.

Like with anything you get in life you get what you pay for
You are really making my RC-life miserable with those revelations. I just invested only 280 Euros in a Sirio XXX (full ceramic) engine with 2611 pipe.
Now you are telling me that if it's cheap, it'll be slow.

Holy crap, now I will have to trash that bundle and wait until the prices go back up.

Could you please give us the rest of your wisdom, before I spent any more money....

If anyone thinks they can buy the SAME engine as the worlds was won with, they are wrong.....

Don't look at how fast the top guys engines are, you can't get that.

Look at how fast local guys engines are
on my track
Nova 12-3sct or JP eagle or 12-3SCT full murnan ceramic wins evey race and pulls on every straight

It's really a bit of both, but more driving SKILL than absolute horsepower. If all things are equal skillwise, it may come down to who's a bit faster in the end. But we all know all things are not, and never will be, equal, at least at our level. You very well could have the fastest, most expensive motor in your car and scream down the straight. But if the guy beside you is a better driver, he's going to beat you with that red dot (or whatever lower prices, possibly slower motor he's using). Conversely, if you think his motor is faster than yours, the more skilled guy can switch cars with you and beat you with your own supposedly slower car.

If you can afford to have the fastest, most expensive motor in your car, and love the thrill of blowing past everyone down the straight, more power to you. But if you're lap times are still in the 24-26 second range, there may be some issues. And while that red dot may not be as fast as a MMRBR3, it's far from slow (and I don't even run one, so I'm not a fanboy sticking up for the motor, either).I saw one consistently in the A main last year in a field crowded with nova based motors (stock & mod).

Motoring down the straight is the easiest way to cut down on lap times.....

It's pretty much a given that you still need to drive good...

I believe it's not important to to know how many teeth that are on the belt.
You need to fine out how many pitches(teeth) are per inch. That can be done pretty easily.

Pass you soon...

Factory Racer,

Where are you located - are you within the Socal area?

Anyway, find out if you can fit a REX RER S3 SG Crank on the Non SG motor you have. If the answer is yes, I'll give you an SG Crank (for free) from an RER motor I once race with.

I just want to help you get your new car up and running for now.

You may also PM Stefan in this forum. I'm sure he knows the answer to our SG Crank question.

Let me know!

Just take Ron's generous offer and pay him for shipping.
The extender is not a good way to run that engine in an on road car. They are never straight and will make your clutch wobble, which in turn will cause gear stripping.

Hey Ron, what else do have to give away for free?

From what I understood is that. You can only use an sg shaft type engine with a centax clutch. I had a bunch of sport engines laying around when I first bought my MTX3. So I made of bunch of phone calls and found that to use a centax type clutch you have to use SG style crank
