How about this: 3 port has no carb restriction (anything up to 9mm may be used); more than 3 ports runs a 7mm carb restrictor. Fiddle with the numbers as appropriate to give a slight edge to the 3 port.

Edit: Way back when, ROAR had a restrictor written into the rules. If I recall correctly, it was really small (5mm?). The power was just about right when the traction went away in the heat of the day in Las Vegas.

If the direction is to head toward motor / power control make it simple - restrict carb inlet - Nova has restrictors listed all the way down to 5.4mm , Pipe restrictions work also but with nothing commercially available probably not a good direction to go. Trying to count ports , check sleeve timing , check crank diameter , crank timing etc. means opening motors up and that will collapse under it's own weight just like the well intentioned 1/10th motor rules did.

All I can say is the 5 port turbo plug Nova I ran was great (I used the 7mm restrictor), its $199, and unlike the Basic Competition 3port version ($169), it comes with a better/stronger conrod, which makes its a better deal and more durable, and it includes 4 restrictor sizes in the box. Also, it has the turbo plug, so I dont have to stock 2 types of plugs at a race when running my other car.

I had a discussion with Phil Trotta in New York about running this motor as Spec at our track. He and others already purchased this motor as they are planning to join the class.

Since my only experience with restrictors has been with Veco McCoys and K&B 3.5's, I'm not sure how the "equivalency" will work out. I think Lon told me he was using a 5.4mm restrictor and apparently it did not hurt the top speed of the Kangaroo.

Just saying it may be a bit more complicated than it first appears...


SuperStock was my favorite! In the MWS we used .100 or .125 flat restrictor buttons not "venturi" shaped AND No Nitro Fuel!!! Engines would hardly start at the optimum needle valve settings! You really had to let them warm up!

Due to noise restrictions the Novarossi 5 port basic motor is the clubmotor at my club. (together with Hypex low noise set). It has been tested very thoroughly in the 4wd class and it works very well. Many are impressed by it after getting over the initial hesitation of running a fixed club motor. The consensus from all is that it is a great "budget" motor and makes for great racing. As far as I have heard they check 3 motors after the race and it doesn't take long to do the check. They check the parts from that dissasembled motor against correct parts so checking is very easy.

I have the combo in my gt due but can't give any comments on it in a pan as I haven't driven it yet due to personal things that got in the way this year.

Thanks for the info. What is the "combo" for this motor? I haven't seen it.

Default MOTOR UP or MOTOR DOWN

If you're thinking about one of these cars but live in fear of being out motored, you haven't been paying attention! This is NOT 4wd! The concept that a hotter motored pan car is a better pan car just hasn't happened. Floating around is a thought that we'll take action if this becomes a problem. So get your hot motor and try to kill the class, this class will kill you first. I would suggest that our New York friends don't get to rapped up in too many rules as that's no fun, it's the racing that's fun!

What is the "Hypex" low noise set? I recall there was a bit of concern at the Toledo track this spring.

Thanks,
Ned

Hi Jeff

Nice meeting you at the GLC! It was great racing with Loran, she was drove really well all week. I should have the motors on my site within a week. If you need one right away please send a pm. I am finishing up my site right now.
Thanks, Jason

+1! These motors are basically air pumps, and you can run as many ports as you want but if you limit what goes thru the carb the rest of it means nothing. After driving the car once it was very evident that this is a traction limited class - too much motor will only slow you down.
