The one with less is of course lighter but I believe it will have less roll resistance. Which is what I would rather have.

also i been told the new head on the flash makes it run alittle hotter if u have the old flash head better to use it..
Myself and some others Factory Novarossi drivers have tested this head for both sedan and 1/8 scale since the last summer. There is absolutely no problem with reliability, temp and performance of the engine. We even use this heads in Houston, last summer in the sedans!! The BIG advantage is the lower CG. The Head of the engine is a heavy part of the car that sits high (after the body shell, of course). By Lowering this one, the handling of the car improves a lot. |

Wrong, it does not run hotter. It read a higher temp because your temp probe is closer to the glow plug. Actually the lower heads have an extra fin.

the head being lowered that little, really effects the handeling that much??
As alot of people have said, the lower you can get the CoG, the flatter and faster you can go through corners (being within all the limitations) |

The few holes Novarossi is drilling in their previous heads are just a few gram. I have drilled 16 holes of 4mm into a head and it did save just 5 gram. |

Maybe for the top 30 world class racers as with electrics those guys can notice a difference if the electric motor is placed a few mm forward. The avarage racer will not notice a thing.....
As for a lower head, I doubt you would feel the difference but it may make a very small difference on the watch. Of course most drivers are not consistent enough to be able to find that slight difference in times in all the background noise of poor driving :D |

In 1/12th I can feel the difference in just a 6 tooth difference in spur, and subsequent pinion change, which moves the motor forward maybe 2 or 3mm.

New lower head. Holes. This. That. The plus 35 was a killer motor as the kangaroo. Prices were on the money too. Now a kangaroo is 449.00. And these new motors are over 700 or close to it. Crazy.

In my opinion, the new head is just a selling item to show the market improvements and I do wonder when they do run out of ideas, to me it is still a 2-stroke engine based on an ABC construction. |
I still think that the 35+21 and +12sct tuned motors are just as fast as the newer nova engines and are a better buy for your money. And they can take alot more abuse. I have seen many pro racers use the 35+21 and +12sct with flash and 353 heads on them to promote the newer engines. If you have the money great buy the new stuff if you don't buy what you can afford it will still be fast.:nod:

A pro who can bust off 10 laps all within .2, small changes become quite noticeable in his laptimes. |
