Roma
 

At close to $400, I would hope the Roma can refuel itself..

:ha::ha::ha:

Ran a 20 main saturday with my P5 in an MBX6T, pitted at 9:55, ran til the 20min mark and had a half track left to go. Finished my lap and ran 3 more laps and it ran out just after the start finish line. Lap times about 27 seconds...so i got roughly 11.5 minutes on a tank with it and they are stump pullers in a truggy. This was with a 7mm venturi and a 2084/21 combo, Werks lightweight clutch with alum shoes and 2 .9s and 2 1.0 springs, 13T bell

Great setup but change the pipe and you will be mo' happy

2096? what will i notice by switching to it?

Better mileage is my guess.

Wat are the needle settings for the Roma guys ( I know there all different). I am only getting about 7.5 - 8 mins, running 2069/21, 6.5 venturi, standard losi clutch. 2 Ali 2 comp. I think I have about 5 or 6 litres through it now. Also running 48 - 15 gearing.

I've been running a "clocked" Roma for half the year (switching between the Roma and the Bonito) and have had no problem getting between 10-11 minutes runtime in the 8T 2.0
I'm using the Nova 9886 pipe and an M2Clutch system and #8 venturi. The gearing - 50T spur and 15T bell. The motor seems deceivingly slow cause it hits top speed so quickly but she's definately not lacking.

Roma/Bonito
 

Besides displacement, what characteristic differences are there between the two engines?? In a truggy

fuel mileage,
torque monter (hard to control, violent)


Thanks

Roma needle settings

Stock 3 1/2 top. 5 bottom

How big is the track you race on? 48-15 is a little odd, why did you go with that gearing?

It tames the bottom end just nicely and has plenty of top end.

Do u know what altitude your at as these are miles away from my settings. I think I'm about 80 - 100 m above sea level


What size Venturi r u using

Those are the stock needle settings.

You can't use other people's needle setting, they have to be tuned to your specific area, humidity, temperature, glow plug, engine age & sleeve wear, and altitude.

Start at the stock needle settings. Lean the bottom until you have a stable, consistent idle, where its doesn't two-stage (idle high, then start idling lower). Once thats done, drive the car and lean the HSN until you get a good top end, but keep it 1/12 turn rich on the HSN just to stay safe.

Where do you live?
