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

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.

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?
