Thats why MAX is still using 14mm crankshafts and not the 14.5mm
Actually it does save time and tools to create such a shape directly in the crankshaft. Producing in large numbers (60.000 a year regarding their promo movie) a short machine time and less maintenance and recalibration is wanted

If you want to lighten a shaft for less mass rotation you must take it from the outside and not from the center....

As far as saving tooling. how is that possible it requires more programing additional cutters and time aslo machine servicing to cut the shape direrectly
calibration is required for both methods .
Max power used the 14mm crank because they required more mass on the delivery end so that there efforts to balance the crank was easier to achieve .

An object traveling in a circle behaves as if it is experiencing an outward force. This force, known as the centrifugal force, depends on the mass of the object, the speed of rotation, and the distance from the center. The more massive the outer object, the greater the force; the greater the speed of the object, the greater the force; and the greater the distance from the center, the greater the force.

I don't really care about ramp vs. no ramp.... these engines make more power than 95% of drivers can use. My point is that if the silicon comes loose while running- kiss your engine bye bye....it will hose the p/s and likely the rear bearing at least.

I agree with you there ive repaired engines where thats happened but if properly maintained it shouldnt happen.

lets end all this speculation and theorys on why Novarossi use this silicon in the shafts. To quote them on their web site, The inlet has a silicon filling to reduce the weight of the crankshaft to improve acceleration. Go to Novarossi site click on Nova Flash engine then click features and this is under crankshaft. Regards Martin.

As also they let you think you need 9 intake ports to go fast.......
Yes, they never gonna tell they have found a cheaper production to make more profit. No, they tell you the new piston is better and the filling works better.....
Ok, lets end this but Alex Siddique is right about rotating mass....

Hello guy's and gal's, I have just opened my 353 09 for the first time since running the car last summer. I found that when turning the crank by hand it seamed a bit notchy, so I tore it completely apart. I found there was a large amount of orange residue on the conrod and at the top of the piston along with a black center on the piston, it also seems that the front bearing is a bit gritty, can I clean the front bearing with brake clear or something to that degree to get the grit out? or is this a sign that a new front bearing is needed? the main bearing still seams smooth with no roughness to it at all. I have pics and will post but the battery on my camera just died LOL.(Charging now) I run the engine with Byrons 20% Race 2000 Gen2 fuel and keep the temp between 240 deg and 280 deg when racing. I did not find there to be any slop in the conrod to crank bushing but I am just a bit worried about the orange colour.
Thanks guy's

Wow! of the 9 years I've been doing this I've never seen a engine internals look this bad... I've ran about 3 gallons of Byrons Gen 2 in my engine and it looked nothing like this. I'm surprised there isn't more damage ..
