is the plus series the latest from novarossi?

yes it is :sneaky:

What engine do you use now ?

Looks okay to me the last last time we met.

The plus series are definetely faster at top speed.

at the moment im using LL5, i bought it 2nd hand tho...
thinking to order a new engine for next year race season. so yeah, im doing some research about engine.
any recommendation?

Go with Nova Plus 12-5ct

MOSMO is the way to go, its the best of the moded novas.

You mean MasMo = Massimo Fantini Modified = Novamax = Max Power Engines

yep the Fantini job is my favorite. I prefer the 3 needle carb and for some reason its just a bit faster than my tuned nova and shows less wear after twice as much use.

Do anybody know how many additional head shims are needed for the 12+3ct?

Yes M. Fantini mod is good, but very pricey and rare.

i have the plus 21-3c i hope it will run good next season :)
is it possible to buy new heads?

depends on what % of nitro you are using

AFM

You do not need any more head shims to run 16-20%. If you want to run 30% you should add at least one .1mm head shim. You may want to add a total of .2mm depending on the weather, and powerband wanted. This is a total of .4-.5mm of total head shims. This should get you close. ;)

I am new to 1/8th and I have something that I have been wondering about and would like to know what you guys think about the subject.

My first and only race with the car on the first qualifier the car was stock with mid to large size tires ( not sure the exact size) and I just made time, came across the line and ran out of fuel.

After that run I put a one tooth smaller spur on second gear because I thought that the car was topping out early on the straight. The car ran out of fuel even earlier. I also put a little more wing in the car so I think that I was getting in the throttle a little bit harder and earlier then in the first qualifier.

For the third round I thought that the tires where getting small so I put the stock spur back on and put a one tooth larger pinion on second and it ran out of fuel even sooner then the other two rounds. I don't know what the over all roll-out was to really be sure.

Is it possible that the engine is more efficient geared higher like in the first round? I do know that I had a faster qualifing time each round untill I would run out of fuel on the last two rounds.

Okay Mark don't get carry away :nod: Not everybody can pay the price :sneaky:
