Thats because this is for a side exhaust engine, so how far do you notch the sleeve? 45 deg to line up the exhaust port?

Oh, I got the side one? Easy fix right?

From what I understand you will just need to line up the exhuast port and then notch the sleeve to seat with the locator pin on the block. Basically you are going to turn the sleeve 90 deg and then your good.

Hope this helps

Oh okay, but is it 90 deg. turn? I'll just make sure that the exhaust port lines up.

This weekend we had our Region 4 Championship. I want to say thanks to Novarossi for providing such great products. I was able to TQ sedan and 1/8 scale and win the Sedan main. I had some issues in the 1/8 scale main, but had the fastest lap and fastest car. Thanks again Nova.

Apart from the aesthetics, what is the difference between 35 Plus 21 and the Cordoba Edition.

I read from earlier post in this thread, the conrod & crankshaft are different for 35plus21, 359 and LC Cordoba.

35plus21 get the biggest conrod's hole diameter, while 359 get the smallest conrod's hole.

can someone share their knowledge/experience on the effects or performance of using the different manifolds on your nova engine?

type - performance
short (3-fins) - ???
medium (4-fins) - ???
lonog (5-fins) - ???

which manifold is best for
12-3SCT
LS3
LL5

A longer manifold will give a longer exhaust system what will result in more bottom power and less top RPM. This is basic 2-stroke theory.

asw7576

Do you know why long manifold would result in more bottom power but less on maximum rpm ?

Roelof

It is all about resonation, the shockwave comming back to the engine act like a exhaust valve keeping the fresh fuel in the motor. Shorter exhaust will give a shorter resonation time which will give the better timing on higher rpm's

All you want to know about 2 stroke engines, their exhausts and tuning:

Okey, thanks..... I know that too. I was testing your education skill.

Roelof

yeah...right.....

Hi guys!

One of my motors is the Collari (1) version of the Nova 35 plus 21 mill. Whatever I do, I can not get the temperature below 120 deg. C. A little bit richer on the HSN needle and the car wont even go into second gear. The motor smokes like a steam train, which is telling me that it is still to rich. Performance is close to other engines on the track, even that rich. Piston/sleeve contact area is smooth with no scratches and compression is very high (hard to turn flywheel over hot and cold). Standard head gap with 0,7mm shim stack. 25% Nitro, Orcan/Serpent fuel (Jonker Netherlands).

I know how to tune an engine, and I ran other engines leaner with temps around 110 deg. C, so I think the Collari "likes" or needs higher temperatures.

Any thoughts or advise on this?

Many thanks in advance!

Regards Stefan

It can be the exhaust, the Sirio 2013 exhaust can make the engine 15 to 20 degrees higher.
