Novarossi have raised their prices to the distributers 10% this season so look at a 15% price hike to us minions I will only get NR engines if its by far the best.


I have a 35PLUS 21

Any of you guys just run on huge tracks? The track I'll be running at is bridgeport CT, which isn't that big. Figure the top would be enough, but thinking of that RB C3 piston sleeve and if it will make my engine weaker than it is or faster if I put it in. I'd receive a great price on it...less than $100.

Anybody try a sts12 rod in there novarossi's?(rear port .12's)

SalvadoriRacing

maybe the opposite....

but who would spend money in a good and reliable engine and then put a poor spare part when relacement is needed....?

Sal-Any advice on my situation? Should I just get new engine later or something, or try that RB C3 p/s set for like $50 in my top?

SalvadoriRacing

can't tell what difference on performance will be noticed..........

if you're thinking of buying a new engine than stick with your top and enjoy it till you get a new one.......

I noticed that the carb on my old X12 has three adjustments and the new one only has two. Why is that?? Would I be better off using the carb off of the old engine on the new one?

Which ROAR legal pipe/header is recommended for a Rex RER S3 on a fairly large fast track?

Thanks,
jag

Skyline is really good and probably your best bet. Otherwise the Sirio pipe is good too but it's expensive and hard to find.

SalvadoriRacing

any brand EFRA 2601 with short (5 fins) conical manifold.......

Hi all,

I am planning to buy an engine for my new MTX-4. I need some advise for getting the most. Here are the facts:

-IFMAR legal. 3 port carb. 5.5 max
-nitro 20%
-9.252 feet (running in Quito)
-no modifications to piston or sleeve.

Thx.

Awesome the RB p/s set is definately going to be purchased for the top. I'm also going to get the RB pipe later on too.

Hey gang. Gotta question. I ran my car today ( MTX-4 ) at my local track and noticed that my engine ( Rex RS3 ) kept on cutting off at about the 3.5 minute mark. This was after the break-in process. I tried changing the glow plug to a #7 and it did the same thing. These are some of the factors im using for this Rex .12 RS3 motor:

1) Fuel: New Byron 30%
2) Plugs: NovaRossi 6 and 7
3) Motor temps: 210-230 degrees F

The motor is new and I just broke it in today. Break-in process:

1) 2 tanks at idle with factory settings ( 15 minute cool down between intervals allowing piston/sleeve expand and contract ).
2) 3-6 tanks ( drove the car by blipping the throttle around the track never hitting full throttle while maintaining and monitoring engine temps ( 150, 160, 170, 180, 190, 200 degrees F ). 10 minute cool down between each tank.
3) 7-15 tanks: started to lean out needles while maintaining tempertures ( 210-230 degrees )

Any ideas on whats going on ? Thanks guys.

your LSN is probably extremely rich........with your car on the bench start the engine and when it reach its working temperature hit full throttle for 2~3 seconds and let it idle...........if after 10 seconds you can't get a smooth acceleration of the engine stalls the LSN is rich........proceed the same way until you get a smooth acceleration and the engine RPM stay consistent when idling for 20~30 seconds........
