I can imagine there is a difference in timings between machine tuned (Novarossi spec) and hand tuned (Ielasi spec).
Machine tuned exactly same with novarossi tuned?

I do not know... All novarossi (based) engines I have seen have a crank closing at 66 degrees max (most 64~65), the Ielasi 9cl is at 71 degrees which I did not dare to go to with my 5T engines.

But as mentioned I can imagine the machine tuned is lower in specs than the hand tuned. If the machine tuned has the same performance there is no use to create a hand tuned.

The "Spec" version of each engine has a hand tuned crankshaft, and piston/liner as well as the ceramic bearing upgrade, the little extra money for the "Spec" version of the engine is for sure worth it on the 9CL, 7CL & 9XL engines.

The 9CL WC edition only comes in hand tuned version with ceramic bearings, this is the engine I would suggest anyone to buy if you are considering the Ielasi Tuned range of engines, it's an absolute monster of an engine.

As Roelof has stated the crank shaft timing on the 9CL WC engines is very aggressive, much higher than most standard Novarossi engines, a standard Novarossi 35 Plus 21 would normally have around 207 degrees of crank duration, the RB CXR Ielasi Tuned engines were around 211.5 degrees for instance.

The 9CL WC is a whooping 220 degrees of crank open duration, and with the lower rotating mass of the 14mm crankshaft, the spool up on these engines is insane, and they produce a monumental amount of high end power.

Roelof, Can you post pictures of the internals of this engines. Thanks.

Timings:

http://www.euronet.nl/users/tooms/timings/timings.jpg

I placed the engine almost at the top of the list. As you can see compared with many other engines and even my modified 5T the closing of the crank of 71 degrees is insane for Novarossi standards. Also the 2 timings on the exhaust port is different, the large middle port is at 95 degrees and the small side at 90.
Also remarkable is the angle of the port. The upper edge of the port is most of the times with an angle for a better flow of the gasses, the port of the 9CL is straight.

This 9CL engine is in numbers much better than the Ielasi tuned RB CX which is also listed.

+1 I ran it last weekend at our final state series race
Motor runs great really like the feel of the powerband felt similiar to the R2101 but with a bit more all around with tons of rpm

I felt the R2101 pulled better through taller gearing, but didn't reach the same RPM as the Ielasi, so you had to run the Nova engines geared quite short to get them to rev and produce the peak HP, where as the OS allowed you to gear taller and the torque would pull through the gearing.

Very different feelings in my opinion, in fact polar opposites.

Because the Ielasi timings are close to an OS I can imagine that they do feel the same. Yes, a different exhaust or manifold can make a huge difference.

Pipe combo
All depends on tracks were here in the states tons of hair pin turns & tracksize varies we have 2 large tracks Kissimmee 255ft straight leading into sweeper 80ft
Homestead Miami 300ft leading into 50ft sweeper both tracks large gearing
The track I tested a bit shorter gearing 19,24 57,61
